How long should a submachine gun storage case quote stay valid?

Answer: Twenty to thirty days. Resin prices move, so longer validity carries an index-linked adjustment clause.

The MOQ is 200; can we start with 80 units?

Answer: Yes, but unit cost rises 15 to 25 percent because colour change and first-article approval are fixed.

How is tooling paid for and who owns it?

Answer: Often half on contract and half after first-shot approval, with ownership passing to the buyer on final payment.

When does the lead time clock start?

Answer: On the later of sample sign-off and deposit receipt, never on the deposit alone.

Three colours in one release — how is MOQ counted?

Answer: Per colour, then summed. Each colour still needs 200 pieces, so three colours at 200 run as one batch.

Submachine Gun Storage Case Procurement: Price, MOQ, Lead Time

Quick answer: A submachine gun storage case is quoted from three blocks — tooling, material and finishing — while MOQ follows the tooling route and colour count, and lead time splits between sample approval and paperwork.

FAQ

1. What a Submachine Gun Storage Case RFQ Must State

A thin RFQ produces quotes nobody can compare. Given only an outside dimension and a quantity, a supplier guesses wall thickness on the safe side, and every extra millimetre returns as a heavier part.

RFQ field	What to state	Cost of omitting it
Internal cavity	L × W × H with tolerance, insert included	Cavity inflated, weight added
Stacking tiers	Storage height and direction	Base ribs and corner blocks dropped
Annual volume and colours	Year total, batch size, units per colour	Amortisation base unclear

Stacking tiers and annual volume are skipped most often. Tiers set base thickness and corner blocks, so a case designed for two tiers but stacked four high is thickened everywhere.

2. How to Read the Four Cost Blocks

Ask for tooling, material, machine time and finishing as separate lines. A rotomolded submachine gun storage case at 820 × 360 × 180 mm with a 6 mm wall weighs 6.8 kg: resin at 11 CNY per kilogramme is about 75 CNY, an 18-minute cycle on a two-cavity arm adds roughly 30 CNY, and four latches with a gasket run add 25 to 35 CNY.

Tooling is the only block that shrinks with volume. An aluminium mould at 35,000 to 60,000 CNY spread over 2,000 pieces is 18 to 30 CNY each; over 200 pieces it is 175 to 300 CNY. A high quote is usually a different denominator, not a fatter margin.

3. MOQ Set by Tooling Route and Colour Batch

The minimum order quantity for a submachine gun storage case is arithmetic rather than negotiation, and the three routes differ by an order of magnitude.

Tooling route	Upfront cost	Typical MOQ	Best fit
Welded steel	Fixtures 2,000–6,000 CNY	30 pcs	Cases over 1 m, low volume
Rotomoulding	Mould 35,000–60,000 CNY	200 pcs	Mid to large batches
Injection moulding	Mould 120,000–250,000 CNY	800 pcs	Small cases, tight cosmetics

Below 30 pieces, welded steel wins because no mould is needed. Colour is the quieter constraint: a change needs a 40-minute clean-out and 3 kg of scrap, so one colour starts at 200.

Room to negotiate sits in batch splitting: 2,400 pieces a year as three batches of 800 keeps tooling spread across 2,400, while a first batch of 200 only moves cost into wall thickness.

4. Samples, Sign-off and Golden Units

Sampling runs three rounds. A printed prototype takes 5 to 7 days and proves outer form and lid feel; the first moulded part takes 8 to 12 days and exposes shrinkage and wall distribution; the signed sample carries colour chip, marking and latches as the production reference.

Keep three golden units from one mould and one resin lot, tagged with date and mould number. Measure wall thickness at six points, accept nothing under 90 percent of nominal, and keep latch force between 30 and 60 N on the loaded submachine gun storage case.

5. Lead Time Milestones and Shipping Documents

Ask for lead time node by node, because sampling and inspection are the stages most often compressed by a verbal promise.

Milestone	Working days	Output
Enquiry to quote	2–4	Quotation and tooling proposal
Prototype to first shot	10–16	Samples with dimension sheet
Sign-off to first batch	25–35	Batch and inspection record
Drop and stack tests	7–12, in parallel	Test report

Paperwork is where schedules quietly die. A sea shipment of submachine gun storage cases needs material certification, an inspection record of measured wall thickness and latch force, IPPC-marked pallets, and a packing list with carton marks.

Testing runs only on real cases, and samples travel to the lab and back in 7 to 12 days, so the test must overlap with production. The model and quantity on the report must match the shipment.

Conclusion

Procurement comes down to three numbers: how many pieces carry the tooling, where the MOQ sits, and how many days paperwork consumes. A complete RFQ makes quotes comparable, and a test schedule running alongside production protects the delivery date. What survives an audit is a submachine gun storage case with measured wall thickness and a full document set.
