Can the 300-unit minimum drop to 100?

Answer: Only with a single-cavity tool: 90,000 across 100 units is 900 each, more than double.

Which audit items matter most?

Answer: Mould ledger, material traceability and first-article records, without which process control leaves no evidence.

Can 49 days be compressed?

Answer: Only the tooling stage, from 16 days of roughing to 11 with pre-hardened stock, adding 22,000.

How should payment terms be negotiated?

Answer: Trade retention and repeat-order pricing before monthly terms, which carry a 1.5 percent premium.

Protective Case Manufacturer Sourcing: Quotes, MOQ, Lead Time

Q: Why do Protective Case Manufacturer quotes differ by 30 percent?

Answer: Tooling and inspection. The same 260,000 mould is 260 a case at 1,000 units and 52 at 5,000, and per-unit inspection adds 6.

Quick answer: Vetting a Protective Case Manufacturer comes down to three numbers: tonnage and cavity count set the minimum order, mould ownership sets how fast a change runs, and the audit score predicts batch consistency.

FAQ

1. What a Protective Case Manufacturer Quote Contains

A quote is six lines under one total: material, machine time, tooling, hardware, inspection with packing, and overhead. Buyers compare only the total, where the soft lines hide.

Material is net weight times resin price: glass-filled polypropylene at 12.8 a kilo, 5.4 kg a case, gives 69. Machine time is 190 an hour on an 800-tonne press at a 13-minute cycle, or 41.

Cost line	1,000	5,000
Resin and colour	73	70
Machine time	41	35
Tooling	260	52
Hardware	24	22
Inspection and packing	9	7
Overhead and margin	45	20

Tooling drives the spread: the same 260,000 mould is 260 a case at 1,000 units and 52 at 5,000, a 208 gap. Inspection on its own line is 0.8 a case; one bundled quality fee adds 6.

2. Checking Capacity and Machine Data

Do not ask how many cases a month a plant makes. Ask for nameplates and cavity counts: output for a Protective Case Manufacturer is daily output per press times running days.

Protective Case Manufacturer: one blue closed case on a pale blue gradient, ring ribs across the lid, three latches at the front, folded handle

A plant claiming 13,000 a month runs an 800-tonne, a 1,300-tonne and a 2,500-tonne press: 101 cases a day from a single cavity at 13 minutes, 176 from two at 15, 240 from four at 22, or 13,400 across 22-hour days over 26 days. Two presses claiming 20,000 would need a 9-minute cycle or a 30-hour day, and a 2,500-tonne press shared across three case types loses a further four hours per change plus 40 minutes of purging.

3. Mould Ownership and Audit Scores

Mould ownership decides how fast a change moves. Of 54 moulds in use, 38 owned and 16 outsourced is 70 percent; an owned mould turns a revised rib in 1.5 days, an outsourced one in 5 to 7 plus a 3,000 fee.

Ask which mould a case number runs on and when it was last serviced. A supplier without an asset number is borrowing capacity.

An audit scores six blocks out of 100, 82 being the usual pass mark: mould 20, equipment 15, traceability 20, process control 25, inspection 12, despatch 8.

Process control is where questions belong: a CPK under 1.33 will not be recovered by tighter sampling.

4. MOQ Follows Cavity Count

A minimum order is arithmetic: tooling divided by the amortisation ceiling, so 260,000 at 800 a case gives 325 units.

Protective Case Manufacturer: four-tier steel racks filled with black closed cases, three timber pallets stacked three high in front

Cavities	Press	Cycle	MOQ	Daily output
1	800 t	13 min	300	101
2	1,300 t	15 min	800	176
4	2,500 t	22 min	1,600	240

More cavities means a higher minimum, because four hours of changeover and six reject shots cost 1,900: 1.2 a case across 1,600 units, 6.3 across 300.

Small volume has two routes: a single-cavity tool at 90,000 brings the minimum to 300, or an existing mould re-coloured for 500 at 12 more a case. Three colours of 200 each count as three purges: quote 600.

5. Lead Time, Batch Consistency and Terms

Lead time is credible only in five stages: 3 days sign-off, 25 tooling, 5 first trial, 12 production, 4 inspection and despatch, or 49 in total.

Stage	Days	Typical slip
Drawing sign-off	3	Two design rounds, plus 4
Tooling	25	Slide rework, plus 3
First trial	5	Colour rework, plus 2
Production	12	Press queue, plus 3
Inspection	4	Third-party slot, plus 2

A repeat order runs 18 days. Batch consistency rests on a 12-point first-article CMM report, wall spread within 0.25 mm and colour within Grey Card grade 4.

Payment is 30 percent deposit, 40 at trial approval, 25 before despatch, 5 retention for 45 days; monthly terms cost 1.5 percent more, or 18 percent annualised.

Conclusion

Buying from a Protective Case Manufacturer is less about the lowest number than about who opens the six cost lines, reconciles cavities with the minimum order and writes audit scores into the contract. Fix mould ownership, amortisation base, inspection frequency and the cost of credit, and the long-run price has somewhere to fall, which is the real test of a Protective Case Manufacturer.
