Quick answer: A reliable ABS trolley tool case supplier itemises shell, hardware, foam and packing, bills tooling separately, and starts lead time at sample sign-back.

1. How an ABS Trolley Tool Case Supplier Builds a Quote
One number on a page leaves nothing to argue with. Ask for four lines: shell, hardware, foam, packing, with tooling and freight outside them.
The shell is priced by weight: 3.6 kg times the compound rate times a 1.05 loss factor, so every 1 CNY per kg of resin moves cost by 3.8 CNY. Put the grade and the pricing date in the quote.
| Line | Basis | Typical share | What to pin down |
|---|---|---|---|
| Shell | weight × resin rate × loss factor | 45 to 55% | grade, loss factor, resin date |
| Hardware | handle, wheels, latches, hinge per set | 25 to 32% | tube diameter, wheel size, bearing |
| Foam | EVA or XPE by area and density | 8 to 12% | density, cutting die included or not |
2. MOQ Tiers and Tooling Amortisation
MOQ follows tonnage and cavitation. An 800 mm case needs a 650 tonne press and a 75 second cycle: about 960 shots a day, below which changeover time has nowhere to go.
Three steps are common at an ABS trolley tool case supplier: 300, 1,000 and 3,000 units. The 300 step costs most; a colour change eats 40 minutes of purging and the first run loses about 3 percent.
| Step | Price index | Tooling | Lead time |
|---|---|---|---|
| 300 units | 100 | billed in full | 35 days |
| 1,000 units | 92 | half absorbed | 38 days |
| 3,000 units | 85 | absorbed, 22.7 CNY per unit | 45 days |
A 68,000 CNY tool over 3,000 units is 22.7 CNY per case; buyer-owned tooling and three free corrections outvalue another 2 CNY off the unit price.
3. Lead Time from Mould to Shipment
Thirty-five days is a sum: 18 of tooling, 3 of trials, 14 of production. What slips is bought-in parts. Masterbatch, hardware samples and the foam die each need 7 days of buffer.
An ABS trolley tool case supplier works backwards from the ship date: loading at seven days, production at fourteen, trials at three, tooling takes the rest. State that the clock starts when the signed sample returns, or courier samples eat two weeks. A 20 ft container holds 480 cases, so 3,000 units ship in three waves.
4. Samples and Pilot Runs
T1 from a temporary tool proves outline and hardware fit. T2 from production tooling proves dimensions, wall, drop and salt spray, with three T1 units and five T2.
Approval numbers: cavity within ±1.0 mm, wall 2.8 mm nominal and never under 2.5 mm, handle play under 8 mm, a 25 kg load held 24 hours must not sink the base past 2 mm. Drop is 1.2 m over ten impacts after four hours at minus 18 °C; salt spray is 48 hours neutral on hardware. A 50 unit pilot needs sign-off in 72 hours.
5. Contract Terms and Shipping Papers
Thirty percent deposit and 70 percent against a bill of lading copy is what an ABS trolley tool case supplier will accept. A deposit under 20 percent reappears in the unit price; over 50 percent and the buyer finances the factory. Quotes hold 30 days, re-openable at 8 percent resin movement, written both ways.
| Clause | Wording to aim for | Note |
|---|---|---|
| Deposit | 30% advance, 70% against B/L copy | below 20% returns as price |
| Price | re-opener at ±8% resin movement | two-way, with grade and date |
| Tooling | buyer-owned, no recharge | three corrections free |
Four documents travel with the goods: packing list, invoice, certificate of origin and a material declaration naming the ABS grade. Keep the description identical to the customs entry, since tool case and plastic box classify differently. Ask which machine ran the last 3,000 unit lot.
Conclusion
Buying ABS trolley tool cases comes down to three sheets: the itemised quote, the quantity ladder, the backward schedule. The supplier worth keeping hands over all three unasked, and that is the test of an ABS trolley tool case supplier.
