What Core Sample and Core Sampling Boxes Are

Core sample boxes and core sampling boxes are dedicated containers for recovering, holding, logging and storing drill core in geological drilling. The core brought up from a hole is first-hand evidence of strata lithology, mineralization and structure, and once it is disordered, damp or broken, later assays and reviews lose their basis. The opening conclusion is that the value of a core box is not merely holding rock but keeping core in depth order without mixing or contamination, loggable and storable long-term. From mineral exploration to engineering geology, a proper core box directly affects the credibility and re-check efficiency of drilling data and is basic equipment for geological archive management.

Digital asset ledgers shift management from reactive to proactive. Give core sample boxes a unique ID and record location, owner and maintenance history, made visible with labels or codes for stocktaking. Accumulated data reveals failure patterns that inform selection, spares and replacement cycles. For multi-site organizations a common ledger also enables cross-region transfer and sharing, raising overall utilization.

Supplier assessment should rest on evidence rather than marketing. Check for citable test reports, liner tooling and whole-case configuration capability, and batch records plus spare supply for core sample boxes. Procure by sample verification against dimensions, sealing, load and appearance. Writing key metrics and acceptance into the contract effectively reduces lot variance and later disputes.

Interior location and zero-clearance retention are the first line of defence. The liner and the item should not shift relative to each other, with extra cushioning at corners and protrusions and cells sized to the largest outline with assembly tolerance allowed. Where core sample boxes carries irregular or fragile items, do a trial fit first to confirm load points and ease of access. Loose filler alone still shifts and collides under sustained vibration.

Requirements for Core Logging and Storage

Core logging and storage impose clear requirements: order by run and depth with legible slot numbering to prevent sequence errors; sufficient load capacity, since core is dense and a full box is heavy; moisture and contamination control so mud, rain and debris do not affect assays; easy handling and stacking for both field and warehouse; and material that resists damp and UV over long storage. A geological core box should cover all five rather than being a simple wooden crate. Missing any one can rob valuable core of its value during storage.

Sustainability and recyclability are long-term trends. Prefer recyclable materials, replaceable parts and standardized structures to reduce whole-case scrapping. core sample boxes should be easy to disassemble and service, with gaskets and liners supplied separately as wear parts to extend the main body life. For export projects, also watch restricted substances and packaging recycling rules, bringing environmental compliance into selection.

Common procurement traps include judging only on unit price, ignoring mould ownership, omitting acceptance criteria, spare shortages and vague lead times. For a long project, lock process and material and agree annual supply for core sample boxes; for custom work, define drawing approval and change control. Putting risk clauses up front costs far less than fixing things later, and volume projects also need sampling ratios and non-conformance handling in writing.

The transport mode changes what matters. Road traffic brings road vibration and frequent handling, sea freight brings salt fog, humidity and long stacking, and air freight brings pressure change and tighter weight limits. Select core sample boxes for the actual mode mix and tighten for the harshest leg where needed. Writing the mode and route into the requirement beats copying a generic specification. See also IP67.

Structure: Slots, Dividers and Load

The structure centres on slots, dividers and load. The usual approach is evenly spaced slots sized to core diameter and length, one piece per slot, with dividers splitting the box into run sections for logging. The base and walls must be strong enough not to collapse when a full box is lifted, and the top should bear stacking load. Slot spacing and depth must match core diameter, since too wide lets core roll and too narrow can pinch and damage it. Where core is boxed right at the wellhead, a core sampling box can be a portable design with handles and label positions to shorten field work.

Standards and compliance are the basis for acceptance. Beyond general protection standards, watch sector-specific rules and transport regulations. Write the applicable standard numbers, test methods and pass criteria into the technical agreement and check them item by item at acceptance rather than substituting experience for evidence. Where core sample boxes is used in a regulated field, complete compliance documents often matter more than the parameters themselves.

Technology moves toward lighter, smarter and more circular products. Structure seeks more stiffness with less material, function adds temperature, humidity and location logging, electronic labels and condition monitoring, and material emphasises recyclability and replaceable parts. core sample boxes selection can reserve upgrade interfaces while meeting current needs, avoiding early obsolescence and easing later digital management.

Air freight and pressure change need dedicated thought. Falling pressure at altitude creates a differential inside a sealed case, making it hard to open or loading the seal; a pressure-equalisation valve or breathing feature eases this while keeping water out. Batteries, liquids or biological samples also bring dangerous-goods rules. Before export, confirm carrier terms and packaging rules for core sample boxes rather than being refused at dispatch.

Material Selection: Wood, Plastic and Stainless Steel

Material choice follows environment and storage life. Wooden core boxes are cheap, breathable and easy to make on site, suiting short-term and field use; PP or PE plastic boxes resist moisture, clean easily and stack well for long-term warehouse storage; stainless or aluminium boxes offer high strength and corrosion resistance for high-value or long-archive core. In wet, rainy regions, prefer moisture-resistant material and mould treatment to stop wooden boxes swelling and rotting. Also weigh box mass, because full boxes of core are already heavy and an over-heavy box adds handling burden and risk.

Customization and modularity must be balanced. Fully non-standard raises cost and spare difficulty, while fully standard may not fit the process. Use a standard case platform with adjustable liners and modular parts to gain both fit and commonality. Customization of core sample boxes should define drawing approval, first-article acceptance and change control so verbal changes do not create inconsistent lots and unclear responsibility.

Structural strength should balance light weight and stiffness. core sample boxes gains rigidity from wall thickness, ribs and corner radii, with local ribs at load points beating a heavier wall overall, and the parting line should avoid sealing and visible faces. Review whether ribs show stress whitening, whether the sealing face is flat and whether latch load is even. Verifying structure before tooling avoids major mould changes after production and is key to cost and lead time.

Cold-chain handover is the critical break for temperature-sensitive contents. Loading, transfer, temporary storage and opening each risk a temperature rise, so define handover windows, pre-cooling and short-term insulation. Export the logger data inside core sample boxes at every handover and check it, tracing any excursion to the exact step. Assigning temperature responsibility step by step beats watching a single stage. See also [](/news/plastic-protective-box/).

Dimensions and Core Diameter Fit

Dimensions should match drilling diameter and core size. Common core diameters run from tens of millimetres to over a hundred, so slot spacing and depth follow accordingly; box length is set by per-run core length and packing method so the box can be moved and stored as a unit. Dimensions also mean compatibility: one exploration project should use a single box type for stacking, numbering and warehouse management. For a core storage box, standard sizing matters more than per-box capacity because it governs logging, retrieval and transport efficiency overall.

Gaskets and wear parts decide long-term reliability. Gaskets age with ozone, UV and abrasion, while latches and hinges loosen from fatigue. Set replacement cycles by usage frequency and stock spares at a share of case count. The maintenance plan for core sample boxes should include sealing-face cleaning, gasket spring checks and hardware tightening, holding sudden failures within an acceptable range.

Liner material follows the object. EVA cuts precisely with clear tooling, EPP recovers well against repeated impact, PU is soft with strong cushioning, and vacuum-formed trays suit fixed volumes. Where core sample boxes carries precision or fragile items, prioritise zero-clearance retention and washability so it does not crumble or sag over time. Material must also be chemically compatible so long contact does not corrode or leave residue.

Handling discipline directly drives breakage rates. Match handles, castors or lifting equipment to the weight instead of manual lifting, spread the load when hoisting and never lift from a single point. The base of core sample boxes should be flat and wear-resistant for forklift or pallet work. Marking prohibited actions on the case itself reduces internal damage from rough handling.

Handling, Stacking and Transport

Handling and stacking are shared needs in field and warehouse. The box should have sensible handles or forklift pockets so a full box can be moved by two people or machinery, and stacking should use anti-slip and locating features to prevent toppling that scrambles core order. Stack height follows box strength and site conditions, since too high crushes lower boxes and core. Secure boxes with straps in transit to reduce shifting and breakage from bumps, adding soft padding inside where needed to protect fragile sections and key horizons.

Environmental adaptability must be verified against real conditions. Where temperature swings are large, confirm brittle and softening points; in damp or salt-spray settings, watch hardware corrosion and gasket ageing; in dusty settings, keep grit out of sealing faces. If core sample boxes is used in extreme environments, test for them rather than reusing conclusions from ordinary conditions. Put the environment into the selection list to avoid rework.

Sealing-face and latch fit decide the real rating. The gasket should be a continuous loop compressed evenly, the sealing face flat without a parting step, and latches positioned and sized to spread pressure and avoid local under-compression that leaks. core sample boxes maintenance should clean the sealing face, check gasket spring and verify latch torque. Judging by gasket material alone while ignoring compression structure is a common cause of sealing failure.

Front-line training often matters more than the equipment. Even a good core sample boxes loses protection if staff do not understand cell purpose, latch sequence and stacking limits. Turn the procedure, checklist and common mistakes into simple graphics and retrain regularly. Recording training and assessment makes it far more likely that equipment is used as designed. See also [](/news/case-seal-materials/).

Moisture, Contamination and Long-Term Storage

Temperature and humidity are hidden risks for many high-value items. Passive protection can rely on sealed moisture barriers, desiccants and insulation, while active control needs phase-change materials, coolant plates or heater pads. Where contents are temperature-sensitive, define the allowable range, hold time and verification method, and place a temperature logger inside so the whole journey is traceable. The thermal plan for core sample boxes should match transit duration and ambient swing rather than simply adding thicker insulation.

Safety and ergonomics affect daily use. Carrying weight, handle position, pushing posture and opening height should follow ergonomics to reduce strain and drop risk. For heavy core sample boxes, provide mechanical handling or castors rather than relying on manual lifting. Round handle and latch edges to prevent cuts; these details directly shape operators acceptance and disciplined use.

Drop and vibration tests should match real transport. Drop uses corners, edges and faces, increasing height while watching deformation and contents; vibration and stacking simulate long haul and storage. Acceptance of core sample boxes should combine simulated transit testing to confirm contents survive rather than testing an empty case. Write test conditions into the agreement instead of letting a one-off result cover every scenario, tightening for the worst case where needed.

Insurance and claims rest on complete evidence. Handover notes, image records, seal numbers and temperature and humidity data together form the chain of responsibility, and a missing link weakens a damage claim. Keep a full trail for high-value lots and secure evidence the moment an incident occurs. The more complete the usage record for core sample boxes, the smoother the claim and the better the feedback into packaging design.

Labelling and Logging Management

Test documentation underpins traceability. Buyers should ask the supplier for material statements, IP test summaries, drop and vibration records, and batch numbers for gasket, latch and hinge. For core sample box, core sampling box, geological core box, drilling core box, core storage box, also keep inspection and sealing-record templates for handover and audit, closing the loop from order to operation. Aligning that evidence with equipment calibration or stocktake cycles makes management smoother.

After-sales and spares are often neglected in selection. Confirm the supplier can supply liners, gaskets and hardware long-term and can support repair and refurbishment. For critical equipment, agree a spare supply period and response time. If core sample boxes can be serviced locally, downtime falls sharply, which is worth more than a one-off low price.

Temperature and humidity control with recording is essential for sensitive contents. Passive designs rely on sealing, desiccant and insulation, active designs on phase-change material, coolant plates or electric control. core sample boxes should define allowable range, hold time and verification method, with a logger inside for traceability. A case only buffers; long storage still needs a stable store, so the two should connect rather than replace each other.

Environmental and compliance demands keep tightening. Materials should be recyclable and easy to disassemble, avoiding mixed-material designs that are hard to recycle, and exports to the EU must watch RoHS and REACH limits on hazardous substances. For a long supply programme, confirm material declarations and a recycling plan for core sample boxes early so rule changes do not cause shortages or returns.

From Downhole Recovery to Surface Boxing

Boxing core from downhole to surface is one continuous flow: after the drill string is pulled, recover core in order, clean and describe it, place it by run into the matching slots of the core box while filling in labels and the logging record, then seal the box and move it to the core library. The key is synchronizing order and labels, because a mismatch or missing tag can almost never be reconstructed later. The core sampling box acts as both temporary bench and transport container here, so it should open easily and allow fast placement to cut field stoppage.

Acceptance and sampling methods should be agreed in advance. Inspect the first article fully for dimensions, sealing, load and appearance, then sample volume lots proportionally with records kept. Sampling should cover the metrics most likely to drift, such as fit dimensions and sealing. Acceptance of core sample boxes should also include simulated transit or drop testing to confirm contents survive real conditions rather than testing an empty case.

Tamper evidence matters just as much in the transfer chain. For high-value items, use one-time seals, serial numbers or electronic labels so that opening leaves a trace and responsibility can be traced. The closure of core sample boxes should work with the seal so the case cannot be opened without damage; at handover, match seal numbers against the manifest with two-person confirmation. For samples or artefacts kept long term, log environmental data inside the case to build a full evidence chain. Writing seal and numbering rules into the procedure sharply cuts substitution, mis-issue and loss, and eases later tracing and accountability.

The custom workflow decides whether a project lands on time. It usually runs from requirement confirmation, concept design, liner sampling and case validation to volume production and delivery acceptance, each step with clear inputs, outputs and sign-off. For non-standard sizes or dedicated liners in core sample boxes, build a functional sample before tooling. Writing the sign-off flow into the contract reduces rework and disputes.

Typical Application Scenarios

Typical uses include solid mineral exploration, oil, gas and shale drilling, engineering geological survey, hydrogeological and geothermal drilling, and research drilling. They share precious, unrepeatable core that needs long storage and repeated review. In these settings the core storage box is infrastructure for geological archive management rather than a consumable. For long-term library storage, borrow the temperature and humidity thinking of high-low temperature test cases to reduce the effect of thermal swing and damp and extend the years over which core can be re-checked.

Common failure modes should be prevented early. Sealing failure usually comes from gasket ageing or foreign matter on the sealing face; structural failure from overload or over-stacking; hardware failure from fatigue or corrosion. The maintenance and use rules for core sample boxes should set checks against these modes to catch problems early. For high-frequency use, shorten the inspection cycle and record each anomaly and its resolution.

Stacking and transit restraint affect safety and efficiency. The case top should have anti-slip ribs or locating bosses and latches must not pop open under stacked load; transit should calculate gross weight against container limits and secure with straps. If core sample boxes is stacked in layers, confirm lower boxes do not deform under long load. Writing stack height and restraint into the procedure sharply cuts toppling and impact risk.

Tooling and drawing approval is the risk peak in custom work. Freeze key dimensions, material and appearance before tooling and state mould ownership and who owns later changes. Drawing changes for core sample boxes should follow a written process so verbal edits do not create inconsistent lots. Clear acceptance criteria and mould ownership are among the most effective controls in custom procurement. See also [](/news/case-foam-material-comparison/).

Shock and Transit Standards

Shock and transit reliability can reference MIL-STD-810H drop and vibration methods, the ISTA transit packaging series and GB/T 4857. Drop tests use corners, edges and faces and check both the case and its contents; vibration and stacking simulate real transport and storage. Acceptance of core sample boxes should judge case deformation and contents integrity together rather than only whether the shell cracked.

Evaluate core sample boxes on whole-life cost rather than unit price. Unit price is only part of it, while maintenance, spares, downtime and replacement often cost more. Repairable designs with replaceable parts and shared standard components cost less over time. For core sample box, core sampling box, geological core box, drilling core box, core storage box, putting spare availability and maintenance convenience into the tender is usually more economical than pressing the price, especially in continuous or non-stop operations where one failure can cost far more than the equipment.

Opening convenience and ergonomics decide front-line acceptance. Handle position, opening angle and latch effort should suit operating habits and reduce bending and strain. Where core sample boxes is heavy, provide castors or mechanical handling. Round handle and latch edges to prevent cuts. These details look minor but directly affect whether equipment is used as intended and how efficient daily work is.

Delivery rhythm should match the use plan. Beyond unit price, confirm minimum order quantity, production lead time, shipping mode and arrival lots, so a single large arrival does not overload storage and split arrivals do not disrupt work. Where core sample boxes faces a seasonal peak, schedule production early and agree an expedite mechanism. Writing milestones and liability into the agreement sharply cuts supply risk.

Procurement and Volume Customization

OEM/ODM and volume customization greatly improve consistency. JUNZHJIA can customize color, silkscreen and liners to brand standards and configure whole cases to a list, cutting on-site assembly. Agree minimum order, lead time, spare ratio and gasket supply cycle, treat sample-case acceptance as a contract milestone, and inspect volume lots to the same standard. Buy core sample boxes on whole-life cost rather than unit price alone.

Supply chain and lead time are easily the weak point of volume projects. Confirm stock and capacity for key parts such as gaskets, latches, hinges and liner material, and agree minimum order, tiered pricing and delivery milestones. For long projects, lock process and material and agree an annual supply so a material change or production halt does not cut off later supply. Writing key milestones into the contract cuts project risk better than a verbal promise.

Labelling and identification underpin management efficiency. Give core sample boxes a unique ID and list, with labels, codes or color coding for stocktaking, retrieval and accountability. Label material should resist weather and moisture so it does not fall off, and mark positions should be uniform for fast recognition. For multi-lot, multi-site management, common labeling rules cut misplacement and loss and feed a digital ledger.

Inventory and turnover reflect management quality. Too little stock risks shortage while too much ties up cash and space, so set safety stock against usage frequency and replenishment lead time. Stock wear parts for core sample boxes in proportion and configure main structures to project demand. Regular counts and turnover analysis reveal idle and lost units and inform the next purchase.

Use, Maintenance and Re-slotting

Maintenance centres on keeping order and blocking moisture. Return each piece to its original slot after review to avoid mis-filing; clean boxes periodically to remove mud and salt, treat wooden boxes against mould and insects, and check plastic boxes for cracked dividers; store off the ground and control warehouse humidity for long-term storage. Folding core boxes into archive asset management, recording box number, hole number and location, raises retrieval efficiency by an order of magnitude. Replace or fully re-slot damaged boxes promptly so core does not scatter and order is not lost.

Quality consistency rests on three lines: process, material and inspection. Lock parameters and tooling in process, control regrind ratio and grade in material, and inspect first article fully plus lot sampling. Batch consistency of core sample boxes strongly affects stacking, liner interchangeability and asset management, so sampling should cover dimensions, sealing, load and appearance rather than one sample. State how non-conforming lots are handled so later batches do not quietly degrade.

Cleaning and disinfection follow the scenario. General settings use water and mild detergent, while clean or medical-related settings need compatible disinfectants and no residue. Liners for core sample boxes should be removable, quick-drying and odor-free. Choose agents carefully to avoid corroding gaskets or reacting with liner material. Writing cleaning steps and cycles into the procedure extends life and preserves protection.

A digital ledger moves management from experience to data. Open a file for each core sample boxes recording ID, configuration, usage, repair and calibration and support scan-to-view. The data can reveal failure patterns, optimise configuration and forecast replacement cycles. For multi-site, multi-lot operations a common ledger cuts misplacement and duplicate buying and eases audit.

Common Misconceptions and Buying Advice

There are four common misconceptions: using an undivided box so order easily scrambles; buying thin wooden boxes for cheapness that fail when lifted full; skipping labels and logging so depth can no longer be matched; and ignoring warehouse humidity so core moulders or weathers. The fix is to write slots, load, labelling and moisture control into the operating procedure and standardize box type for manageability. For drilling core boxes and core storage boxes, a disciplined workflow and a qualified box matter equally, and neither substitutes for the other.

Logistics and storage fit directly affect efficiency. core sample boxes should suit common pallets, shelving and container dimensions to avoid wasted space, stack stably against toppling, and be easy to handle by forklift or hand. For multi-site transfers, a single case type and numbering lets spares and liners interchange and cuts management complexity. Bringing logistics limits into selection early avoids re-tooling the case later.

Spares and repair strategy should be planned early. Gaskets, latches, hinges and liners are common wear parts, so set replacement cycles by usage and stock a share of them. If the main structure of core sample boxes can be repaired and its parts replaced, long-term cost falls noticeably. For critical equipment, agree a spare supply period and response time, and keep assembly drawings for local handling.

Turnaround and reuse decide long-term cost. If a high-value core sample boxes is used one way only, the amortised cost stays high; build a pooling pool, give every case a unique ID and track where it goes so the outlay is spread over many trips. Inspect and clean each unit on return and retire damaged ones promptly. Folding turnover into performance review encourages disciplined use and timely recovery and cuts loss and damage from casual storage.

Frequently Asked Questions (FAQ)

Question: Why must a core box have dividers? Answer: Dividers fix the core and keep depth order. If core can roll freely in the box, it collides and breaks during handling and transport, and depth order easily scrambles, after which assays and reviews lose their correspondence. Evenly spaced slots confine each piece to its own position, reducing collision and letting a logger see horizon order at a glance. Slot width should match core diameter, since too wide allows movement and too narrow pinches and damages. For long-term storage, slots also aid numbering and retrieval, so dividers are not an optional comfort but a basic requirement for data credibility.

Question: Wooden or plastic core boxes? Answer: Judge by storage duration and environment. Wooden boxes are cheap, breathable and easy to make in the field, suiting short-term and on-site use, but in wet, rainy regions they mould, warp and suffer insects, so they are poor for long storage. Plastic PP or PE boxes resist moisture, clean easily, stack well and have moderate weight, suiting long-term warehouse storage and controlled management; stainless or aluminium boxes are stronger and more corrosion-resistant for high-value core. In practice, use wooden boxes for short field periods to save cost and switch to plastic or metal for library storage, standardizing box type for stacking and numbering.

Question: How much load can a core box take? Answer: It depends on material, section thickness and reinforcement, so there is no single number. Wooden boxes gain capacity from thicker side panels and base cross-bracing, plastic boxes from ribs and base structure, and metal boxes carry the most. Because core is dense, a full box is heavier than intuition suggests, so design to the maximum expected load with a safety margin. Verify with a loaded static and stacking test for deformation. For multi-layer stacking, confirm the lower boxes do not collapse or warp under long-term load, and write the rated load and test method into the contract rather than relying on claims.

Question: Can core be stored long-term? Answer: Yes, with the right box and warehouse conditions. Core is an unrepeatable physical archive, and long-term storage hinges on moisture control, contamination control, avoiding sharp thermal swing and preserving order. Use a moisture-resistant box, place it on off-ground shelving, control warehouse humidity, zone the store and treat for mould where needed. For easily weathered or saline core, add a sealed inner bag or protective treatment. Keep a logging ledger and periodic inspection of location and condition. In a damp, uncontrolled store even a good box may not prevent mould or weathering, so box and store must be planned together.

Question: How do I choose core box dimensions? Answer: First fix core diameter from the drilling size, then set slot spacing and depth, and finally set box length and slot count from per-run core length and packing method. One project should use a single box type to avoid unstable stacking and management confusion. Dimensions should also suit the handling method and container limits, adapting a standard box to forklift or pallet where needed. For a core storage box, standardized sizing pays back far more than extra per-box capacity, since it directly affects logging, retrieval and transport. Provide hole diameter, run length and shelf size together for a one-pass decision.

Question: What matters when transporting core in the field? Answer: Restraint, cushioning and order. Before transport, confirm core is slotted by run with labels, and the lid is latched or strapped; secure boxes in the vehicle so they cannot collide or topple; add soft padding in slots for fragile or key horizons. Road vibration is the main source of breakage and disorder, so never leave core boxes loose in a truck bed. For long hauls, use a box with locating features and add second-stage restraint. On arrival, verify order and count promptly and record any problem, so responsibility is not left unclear afterwards.

Question: Does a core box need moisture treatment? Answer: Yes, especially in wet regions or for long storage. Wooden boxes can be treated against mould and rot and should not touch the ground directly; plastic and metal boxes resist moisture but still need attention to internal condensation and sealing. Control warehouse humidity and store off the ground, adding desiccant inside where useful. For saline, sulphurous or easily weathered core, moisture control and isolation matter more, so add an inner bag or zone seal. Moisture protection guards not only the rock but the labels and logging documents, and combining it with store management is what extends re-check life.

Question: How are customization and volume supply arranged? Answer: Define core diameter, run length, load requirement and storage life first, then fix material, slot specification and box size. Volume projects should use a single box type with spares reserved for reordering and stacking. The contract should state material, load, slot tolerance and acceptance method, with sample-box verification as a milestone. Tooling or special structures raise the minimum order and lead time. JUNZHJIA can configure boxes and liners to a hole diameter and run list, but final acceptance still rests on sample approval and lot inspection.

Question: Can core boxes be reused? Answer: Yes, but assess condition and contamination risk. Intact plastic or metal boxes can be reused after cleaning, but check for cracked dividers, reduced load capacity and residue that could affect assays. Before reusing wooden boxes, confirm no mould or insects, and replace where needed. For core with special minerals or strict assay needs, use dedicated or new boxes to avoid cross-contamination. On reuse, re-number and update the ledger so hole number and depth stay matched despite the box change. Folding box condition into inspection balances cost and data reliability.

Conclusion and Related Reading

For Geological Core Sample Boxes, the key is to move use scenario and risk metrics forward into design and to land them through sample-case acceptance and lot inspection. JUNZHJIA can provide material, sealing, liner and whole-case customization to requirement, but final acceptance rests on physical verification.
