If your product is moulded, stamped, die-cast or extruded, there is an invoice that arrives before any sellable unit exists: the tooling. This article is for businesses manufacturing their own product in China in commercial volumes — from roughly 1,000 units per order — who need to know what a mould costs, what makes it expensive, and what happens to it when the relationship with the factory ends. That last part is where the real money is, and it is almost never discussed until the day you want to leave.
What tooling is, and why it is billed separately
Tooling is the set of hard steel parts that shape your product: injection moulds, stamping dies, die-casting dies, extrusion profiles, plus the jigs and fixtures used to assemble and test it. It is custom, it is built once, and it belongs to your product rather than to the factory's catalogue — which is why it is quoted separately from the unit price. It is also the reason the first order and the tenth order have completely different economics: order one carries the tooling, order ten does not. Where tooling sits in the wider chain is in how manufacturing in China actually works.
What a mould costs
Ranges below are what the market typically quotes for a Chinese toolmaker. Treat them as orientation, not a quote:
- Soft or aluminium tooling (low volume, prototype bridge): $800–$3,000
- Simple single-cavity steel injection mould: $1,500–$5,000
- Multi-cavity mould (4–8 cavities), moderate complexity: $6,000–$20,000
- Large or technically complex mould (slides, undercuts, hot runner): $20,000–$80,000+
- Stamping die, simple part: $1,000–$6,000; progressive dies run far higher
- Die-casting die (aluminium/zinc): $4,000–$25,000
- Assembly jigs and test fixtures: $300–$3,000 each
The same drawing can produce quotes that differ threefold between toolmakers. That is not always a scam — it usually means different steel, different cavity counts and a different expected life, which is why comparing tooling quotes without comparing specifications is meaningless.
What drives the price
- Cavity count. Two cavities roughly double output per cycle and add far less than double the cost — but only pay for cavities your volume actually needs.
- Steel grade. P20 for moderate runs, 718 for tougher duty, H13 and S136 for high volume or corrosive materials. Steel choice is the main lever between a cheap mould and a long-lived one.
- Hot runner vs cold runner. Hot runner costs more up front and saves material on every shot; it pays back only above a certain volume.
- Geometry. Undercuts, slides, lifters and threads each add mechanisms, cost and failure points. This is exactly what a factory tries to simplify at the design-for-manufacturing stage.
- Surface finish and texture. Polished optical surfaces and specified textures add real cost.
- Tolerances. Tight tolerances mean slower machining, more inspection, more steel.
How long tooling lasts
Mould life is measured in shots, not years:
- Aluminium or soft tooling: 5,000–50,000 shots
- P20 steel: 300,000–500,000 shots
- Hardened H13 / S136: 1,000,000+ shots
Ask for the guaranteed shot count in writing, and ask who pays for maintenance, spare inserts and refurbishment. A mould that runs continuously needs servicing; the question is whose cost that is. Getting this into the agreement is part of what a contract with a Chinese factory must contain.
The real question: who owns it
Paying for a mould and owning a mould are not the same thing in practice. The mould stays physically inside the factory, and physical possession is nine-tenths of the argument. Three arrangements exist in the market:
- You pay in full and own it. The clean case — provided ownership is documented.
- "Free mould" amortised into the unit price. The factory carries the tooling cost and recovers it across your orders. Nothing is free: you are paying for it per unit, usually with a volume commitment, and the factory owns it. This is the most common lock-in mechanism in Chinese manufacturing.
- Shared or factory-owned tooling. The mould was not built for you at all, or your design ends up in tooling the factory also runs for someone else — which is one path by which your product appears on the market with someone else's brand. Countermeasures are in protecting a batch from counterfeits.
What must be in the contract
- Explicit ownership of the tooling by your company, effective on final payment.
- A tooling list with mould numbers, photographs of the engraved ID, and the storage location.
- The right to remove or transfer the tooling at your request, with the maximum handover period stated.
- Exclusivity: the tooling may not be used to produce for any other customer.
- Maintenance responsibility, guaranteed shot count, and what happens if the mould fails early.
- A condition on the balance payment: photographs of the marked tooling before the final transfer.
Without these clauses you have an invoice, not an asset. Where tooling belongs in your total cost picture is covered in the cost breakdown of a China sourcing project.
Moving a mould to another factory
It is possible, and it is routine, when ownership was documented from the start. Budget for it realistically: dismantling and transport inside China, inspection and often refurbishment on arrival, re-qualification and new samples at the new plant, because no two machines run identically. Plan two to six weeks and a four-figure sum, not a phone call.
Without documented ownership the outcome is different: the mould stays where it is, and the leverage moves entirely to the factory. That is the single most common reason importers stay with a supplier they have already stopped trusting — a trap that starts much earlier, at the point where a trader was mistaken for a manufacturer.
A mould is the only thing in your supply chain that you pay for in full and never physically hold. Whoever holds it sets the terms of every future negotiation — so it is worth spending an hour on the ownership clause before spending $20,000 on the steel.
Getting the tooling question right the first time
We negotiate tooling as a separate commercial item on our clients' behalf: specification and shot count, ownership and marking, storage, exclusivity, and the right to transfer. We verify the factory before any tooling deposit leaves — legal checks and a site visit, the same protocol behind 3,500+ deliveries and 340+ verified suppliers over seven years. Real projects are in our case studies.
Start with product sourcing or a targeted supplier verification if you already have a factory in mind.
