How does a private label plastic tool box differ from contract moulding?

Answer: Contract moulding follows your drawing unchanged. A private label plastic tool box lets the supplier modify structure, inserts and marking on an existing tool, so allow 10 more days.

Can a 500-unit order be accepted?

Answer: Yes, at about twenty percent over the 3,000-unit price, driven by tooling amortisation and purging.

Is the tooling fee refundable?

Answer: Half at 5,000 cumulative units and all of it at 10,000 is common, so fix the trigger and the settlement method in the contract.

Why is your lead time longer than others quote?

Answer: The 45 to 60 days include tooling, T1 and correction. A 30-day offer usually means a colour change on an existing mould.

What if the first batch fails inspection?

Answer: The lot is held under an AQL 1.0 plan with zero tolerance on class A defects. The supplier reworks within 7 days, the sample doubles, and load tests repeat.

Private Label Plastic Tool Box: Quote, MOQ and Lead Time

Quick answer: A private label plastic tool box is priced in four blocks: tooling, shot weight against resin price, hardware and packaging. Moulding starts at 500 units single colour, a colour change needs a 25 kg drum, and the calendar runs 45 to 60 days.

1. How a Private Label Plastic Tool Box Quote Is Built

A private label plastic tool box is quoted in four blocks, never one lump: tooling, shot weight against resin price, hardware and packaging. The gap between suppliers on the same drawing sits in how those blocks are bounded.

Tooling is where padding hides. A body mould for a 600 by 400 by 200 mm case costs about RMB 30,000 in hardened steel: RMB 10 a unit across 3,000 pieces, RMB 3 across 10,000, so ask what quantity the price is amortised over. A 1.9 kg PP body at RMB 9,000 a tonne carries about RMB 18 of resin; stainless hardware costs RMB 6 more a set.

Block	Basis	Buyer supplies
Tooling	Mould cost by units	Annual volume, ownership
Resin	Shot weight × 1.05	Grade, colour, rating
Hardware	Per set	Latch material, handle load

2. MOQ Lines for Mould Colour and Packaging

Split the minimum into three lines. Moulding follows the press, where 500 units single colour is the floor; colour follows the drum, at 25 kg minimum; printing follows the plate, 1,000 for screen and 2,000 for pad.

The drum is the line buyers forget: off-white, yellow and olive need a barrel purge at every change, and the purged resin lands on the buyer's invoice. A first batch in natural, colour on the second run, trades one order for one purge.

3. Lead Time from Tooling to Shipment

Seven checkpoints run in series: artwork 3 days, prototype 8, mould 28, T1 and correction 12, production 22, inspection 2, booking 7. That chains to 45 to 60 days, and a slip at any point moves everything behind it.

Stage	Days	Where it stalls
Artwork	3	Cavity or insert pockets
Mould	28	Tool shop queue
T1 and fix	12	Sink and warpage
Production	22	Hardware late
Inspection	9	Space and cut-off

A busy tool shop stretches 28 days to 35, and 22 days of production assumes 1,000 units on one cavity across two shifts. Write the clause as 22 days from T1 approval, not 60 from the order.

4. Cost Items That Must Be Fixed

Private Label Plastic Tool Box: closed grey case on a scuffed bench, recessed panel, moulded handle, one latch, parts bins and a lamp behind

Five items belong in writing: mould ownership, resin linkage, colour tolerance, packing and acceptance limits.

Resin linkage is most often skipped: PP moves twenty percent a year, so price should follow shot weight once the tonne price shifts RMB 500. Colour needs numbers, ΔE within 1.5 inside a batch and 2.5 across. Acceptance is not match the sample: plus or minus 1.2 mm on the cavity, 2.5 mm minimum wall, 5,000 latch cycles, a handle holding 25 kg for 10 minutes.

5. Factory Audit and First Batch Control

Audit five things. Press tonnage first, since a 600 mm case needs 800 tonnes of clamp; then the mould register; lot traceability from case to compound batch; salt spray reports; and a packing line with separate labelling and sealing.

Audit item	Look at	Pass line
Presses	Tonnage, count	Two or more at 800 t
Moulds	Register, log	Numbered and racked
Lots	Traceability	Back to compound batch
Hardware	Salt spray	Grade 9 at 48 hours

First-batch risk sits in colour, assembly and hardware: five cases side by side under one light, 20 for latch feel and lid gap, 10 hardware sets for load and cycles.

Conclusion

Buying a private label plastic tool box comes down to three boundaries: which four blocks build the price, which three lines set the minimum, which seven checkpoints set the calendar. Send the parameters before asking for the number, and the private label plastic tool box project moves faster than any round of price pressure.
