The quotes differ by 30 yuan. Is travel case production cutting material?

Answer: Ask for a cost breakdown, then check shell weight against a weighing, hardware brand, and how often tooling is charged. If those line up, the gap is terms and volume.

Why is 300 units 54 yuan dearer than 3000?

Answer: Fixed cost has nowhere to hide. At 300 units tooling is 50 yuan and setup with first-off 12 yuan; at 3000 those two lines total 8.1 yuan.

Who should pay for tooling?

Answer: Buyer-funded if cash allows, because title is clean and the moulds can move. For a lower price accept factory funding, but fix the amortisation count and transfer deadline.

How much does a 60-day account cost in travel case production?

Answer: About 1.1% at an annualised 6.5%, roughly 4300 yuan on 3000 units at 132. Compare terms and price in one table, or a cheap price on a long account wins the wrong order.

Which Travel Case Production Quote Is Real at 3000 Units?

Quick answer: The gap is not margin but how the quote is written: whether tooling sits in the unit price, whether regrind is blended in, who pays packing and inspection, and what an open account costs.

FAQ

1. Where 110,000 yuan goes in travel case production

One drawing, one quantity of 3000, and six factories quoted between 132 and 169 yuan a unit. Across 3000 units that is 111,000 yuan. Four things account for the 37 yuan: tooling charged inside the price or billed apart, regrind blended into the shell, packing and inspection billed to whom, and the discount rate on an open account.

Travel case production is negotiated the other way round: settle definitions first, because only about 5 yuan of the spread is real processing profit, and a mismatch leaves the comparison sheet as decoration.

2. Unpacking the quote line by line

A quote has to break into cost lines before anyone can judge it. The table splits a 169 yuan offer.

Travel Case Production: a grey case open on a timber shelf, red-handled tools and a grey meter in foam, cartons and coiled cables beside it

Cost line	Per unit	Share	Where it gets moved
Shell material	59.3 yuan	35%	30% regrind saves 8.4 yuan
Assembly labour	17.6 yuan	10%	Quoted 9 minutes, run at 11
Hardware	44.2 yuan	26%	Trolley tube 1.2 to 0.9 mm
Tooling	6.0 yuan	4%	Charged again next batch
Margin	13.5 yuan	8%	Thin margin, extras billed apart

Material is easiest to check: a shell weighs 2.6 kg net, PC granulate runs 21.5 yuan a kilogram and sprue loss adds 6%, so 59.3 yuan. Blending 30% regrind drops it to 50.9 yuan and doubles corner cracking in a -20℃ drop.

Hardware carries 28 yuan of trolley, 12.8 yuan of wheels and 3.4 yuan of latches; a 10 yuan saving there usually means a thinner tube or a zinc axle.

3. Volume: what separates 300 units from 3000

Minimum quantities are the cost of a changeover that cannot be spread: on one tool set, 300 units and 3000 units differ by 54 yuan a unit, almost all of it fixed.

Batch	Unit price	Tooling	Setup and first-off	Gap against 3000
300	186 yuan	50 yuan	12 yuan	54 yuan higher
1000	152 yuan	15 yuan	5 yuan	20 yuan higher
3000	132 yuan	6 yuan	2.1 yuan	baseline

Tooling totals 180,000 yuan across six moulds, so a single pass-through is 60 yuan a unit; a quote showing 50, 15 or 6 spreads the rest over three instalments. When that line shrinks, the money has moved.

A changeover costs 6 hours, a colour purge 2 hours and 3 rounds of first-off inspection: 12 yuan at 300 units against 2.1 at 3000, which is why small orders in travel case production are expensive.

The deal worth arguing for is a first batch of 300 with a rebate once volume reaches 3000 inside six months.

4. Tooling ownership: who pays and who holds

Tooling is the only asset that cannot walk out with the goods: six moulds at 180,000 yuan, about 80,000 shots, or 26 batches.

Travel Case Production: a grey hard case flat on a grey shelf, two metal catches closed, a folding handle and round vent at the centre

Model	Who pays	Title	On a supplier change
Buyer-funded	180,000 yuan	Buyer	Movable, 30,000 yuan to strip and reset
Factory-funded	Spread into price	Factory	Balance settled at about 60%
Shared	Half each	Joint, in writing	Disposal clause in the annex

Buyer-funded is cleanest but ties up cash and leaves the moulds elsewhere. Factory-funded lowers the price but locks the account for three years.

Shared ownership fails most often: joint title is written, disposal rights are not. Stamp a mould number on the frame, hand over a trial report per mould, and set a 30-day transfer window. Travel case production also hides modification, 4000 to 9000 yuan a change, so put two free changes in year one into the contract.

5. Six milestones inside a 45-day lead time

Travel case production quotes 45 days, and that has to become six checkable dates: sample approval 7 days, tool trial 12, material arrival 7, moulding 9, assembly 6, inspection and despatch 4.

In travel case production, moulding assumes a single-cavity tool on a 78-second cycle and two machines at 22 hours a day, about 5.5 days of net running for 3000 units. Four out of five delays sit in the 12-day tool trial: a failed first shot means a 5-day correction, a second failure another 5, and 45 days becomes 55.

6. Payment terms, samples and audits

Stage	Share	Trigger	Common trap
Deposit	30%	7 days after signing	Written as a token sum, not refundable
Tooling	20%	First-off approval	Folded into deposit, title unclear
Before shipment	40%	Signed inspection report	Inspection at 800 yuan per person-day
Retention	10%	60 days after arrival	No deduction clause, so it is a free loan

An open account is not free money: at an annualised 6.5%, 60 days adds about 1.1% to the unit price and 120 days adds 2.2%. Two quotes 2 yuan apart at 30 and 90 days are not 2 yuan apart.

Samples cost 1200 yuan a design, refundable against volume. Audits come in three passes, and the third, three days before despatch, is the one to attend on any travel case production order.

Conclusion

Of the 111,000 yuan spread, only about 5 yuan a unit is processing profit worth arguing over; the rest sits in definitions, volume, tooling and terms. Fix the quote sheet structure, then the price, then the tooling title and delivery windows in the annex. Reading a cost table saves more than bargaining, which is the part of travel case production worth learning.
