Why is an artillery shell box quote valid for only thirty days?

Answer: Steel and resin move with the market, and thirty days is the longest lock most plants carry; longer projects carry an index-linked clause.

The MOQ is 300 units. Can we start with 100?

Answer: Once the mould exists, yes, but unit cost rises fifteen to twenty-five percent because moulding hours and colour changes are fixed.

Welded steel or rotomoulding?

Answer: Over 1.2 metres and under 300 units a year, steel is cheaper and faster; otherwise rotomoulding wins on cost.

Should the sampling fee be paid?

Answer: Yes, with an offset clause: credited in full when the first order reaches the agreed quantity, tooling passing to the buyer on payment.

When does lead time start?

Answer: At whichever comes later, sign-off or deposit. Starting the clock at deposit alone lets a delayed sign-off slide the date.

Artillery Shell Box Procurement: Price, MOQ and Lead Time

Quick answer: An artillery shell box is priced by tooling amortisation, material weight and assembly; its minimum order quantity follows the tooling route; its lead time splits between sampling and compliance paperwork.

FAQ

1. Six items an inquiry must carry

An artillery shell box inquiry with only length, width, height and quantity returns conservative: the supplier must assume the thickest wall and costliest finish. Six items cut that spread to ten percent.

Item	State this	Risk if missing
Internal size	L, W, H, tolerance, liner	Case oversized, heavier
Loaded weight	Total per loaded case	Wall unfixed
Stacking tiers	Tiers, direction	Base reinforcement dropped
Service temperature	Lowest, highest ambient	Wrong resin grade
Annual volume	Year total, batch size	No amortisation basis

Tiers and volume get dropped most. Tiers set reinforcement in base and corners; volume sets the tooling denominator, and one mould over three thousand units rather than ten thousand moves price by over ten yuan.

2. What the quoted price is made of

A rotomolded case of 900 by 600 by 420 millimetres and 7 millimetre wall weighs 18 to 22 kilograms. Resin at 12 yuan a kilogram is about 240 yuan, the carousel runs 25 minutes a part, and four latches with a gasket add 60 to 80 yuan.

Tooling is the only line that amortises: an aluminium mould at 40,000 to 80,000 yuan over five thousand units adds 8 to 16 yuan a case, over eight hundred units 50 to 100.

Material needs a grade and a weight: resin at 0.92 and 0.94 density differs by three to five percent at equal wall, and antistatic masterbatch adds eight to twelve.

3. Minimum order quantity follows the tooling route

MOQ is arithmetic, not a negotiating position. Three routes differ by an order of magnitude.

Route	Upfront	Usual MOQ	Fits
Welded steel	Jigs, 3,000 to 10,000 yuan	50	Over 1.2 metres, low volume
Rotomoulding	Mould, 40,000 to 80,000 yuan	300	Curved ribs, mid volume
Injection	Mould, 150,000 to 300,000 yuan	1,000	Small, high finish

Below fifty units welded steel wins: no mould, per-piece pricing, but more labour and a twenty unit minimum per colour change. Above three hundred, rotomoulding spreads the mould and the one-piece body has no seam.

Negotiate by splitting batches, not cutting price: three thousand a year in three batches keeps the denominator intact, while three hundred invites thinner walls.

4. Three sample rounds and what to sign off

Three rounds: a foam hand sample in seven to ten days for dimensions and lid feel; the first shot, for sink marks and wall distribution; the signed sample with chip, print, latches and liner.

Keep three signed artillery shell box samples from one cavity. Wall is read at six points, the thinnest at ninety percent of nominal; colour within two Delta E; a loaded 1.2 metre drop onto six faces; latch effort averaged over three pulls. Colour, print and liner layout change with a new chip; wall, parting line and latch model restart sampling.

5. Lead time and transport compliance documents

Ask by milestone, not one number: sampling takes twelve to eighteen days, sign-off to first batch thirty to forty, a reorder eighteen to twenty-five.

An artillery shell box moving by sea needs four document sets: drop, stack and leak reports; mill certificates plus resin batch reports; fumigation proof with the IPPC mark on the pallet; and the UN packaging mark with category letter, gross mass, month, country and maker code, characters 12 millimetres high.

Laboratory slots take ten to fifteen days, so testing runs beside production. A wrong engraving in the mould costs more than the check at sign-off.

Conclusion

Three numbers decide the order: units the tooling covers, the threshold the quantity clears, and days the paperwork is allowed. A complete inquiry makes quotes comparable, a written amortisation rule keeps the price honest, and testing beside production keeps the date. That is what makes an artillery shell box order workable.
