YIVAHUBWho Owns the Mould? Tooling Ownership, Release and How to Move It to Another Factory
2026-10-20 · YIVAHUB Team
Every buyer knows they should own the tooling. Few end up owning all of it, because the mould is not one asset. It is three, held in three places, and the one most buyers secure is usually the least useful when they try to leave.
The three assets are the steel, the programs and the process. The steel is the physical tool: a die-cast mould for a housing, an injection tool for a diffuser, a stamping die for a metal shade, a welding fixture for a furniture frame. The programs are the digital half: 3D files, electrode drawings, CNC programs and EDM settings that cut the steel. The process is the knowledge: the machine, the tonnage, the temperatures, the cycle time and the small adjustments that make a tool produce good parts rather than merely close ones. Buyers pay for the steel, forget to ask for the programs, and never think about the third until parts off a new machine do not match the samples.
A mould paid for by the factory is the factory's asset, whatever the conversation was. This is the most common failure and it is rarely a trick: the buyer asks for a price, the factory quotes a unit price that absorbs the tooling, and everyone moves on. Lighting and furniture tooling sits in a wide band. A small injection tool can be a few thousand renminbi; a mid-complexity die-cast tool for a housing typically runs 20,000 to 80,000; a large multi-slide tool or a glass mould for a specific profile can pass 100,000. If the tooling is not a separate line on the invoice with your name on it, you do not own it, and you will find that out at the worst possible moment.
Make ownership a document, not a sentence in an email. Three things make it real. A separate tooling invoice in your name describing the tool, its dimensions, its weight and the part it makes. A signed ownership letter from the factory stating that the tool was paid for by you, is held on your behalf, will be maintained in working order, and will be released on request once open orders and any tooling balance are settled. And a line in the purchase order referencing the tool number. Add an asset tag stamped on the mould base, a photograph of the tool with the tag and a ruler in frame, and a yearly refresh of that set so you can see wear and modification. Without these you have a commercial understanding, and a commercial understanding is not something a lawyer or a new factory can act on.
Where the tool physically sits is a trade-off, not a formality. Factory-held is normal, cheapest and usually correct: a tool that lives where it is used gets maintained, and transport costs money. Two alternatives are worth it for high-value tooling. A third-party tool room holds the tool between runs and is paid to maintain it, which costs a little logistics and removes real leverage from the factory. Your own premises is the third, and almost no overseas buyer does it, because the tool then has to be shipped back for every production run.
The lock-in nobody mentions is machine compatibility. A mould is built for a machine class: a tonnage range, a platen size, a sprue position, a maximum daylight. A tool built for a 160-tonne press with an unusual platen will not run in the next factory down the road, and moving it means finding a matching machine or paying for a modification. The fix costs nothing at the design stage: specify a standard mould base and a common machine class in the tooling order, and name the machine class in the ownership letter. The same applies to the digital half. If the factory will not hand over the CNC programs and electrode drawings, the steel you own is a paperweight only they can reproduce.
Moving the tool is a procedure, and doing it out of order causes the damage. Settle the tooling balance and any open orders first, because a factory holding an unpaid invoice has a legitimate reason to keep the tool. Get the release letter in writing, listing the tools and their condition, before anything is crated. Book transport yourself or through your agent rather than letting the releasing factory arrange it, and photograph the tool loaded and sealed, because the most common dispute in a move is the condition on arrival. Domestic freight is a few hundred renminbi for a normal tool, more for a large one needing a crate and a truck with a crane. Then re-qualify rather than assuming it will run.
Re-qualification takes four to eight weeks and is not optional. A moved tool needs a trial run, a first-article sample compared against your retained sample from the previous factory, a dimensional report against the drawing, and a small pilot batch inspected before the full order. Tooling that has been idle or transported can shift alignment, and a factory receiving a tool it did not build will not know its quirks. Budget four to eight weeks including the trial, the sample and one round of adjustment, and make the first order at the new factory a smaller one.
Keep a tooling ledger and treat maintenance as a line item. Record the tool number, the part, the cavity count, the tool life rating, the cumulative shots if the factory will report them, and the last maintenance date. Standard steel tools typically run 100,000 to 500,000 shots before they need real work; hardened tools go well past that. Ask for maintenance every 20,000 to 50,000 shots or annually, whichever comes first, and agree the cost in advance rather than discovering it when a tool starts flashing. A maintained tool is an asset; a tool run until it fails is a delay you have already paid for.
The hard cases, and what actually helps. If a factory refuses to release a tool you paid for, the levers are the signed ownership letter, the invoice in your name, and any outstanding order you can hold. If the drawings are stale because the tool was modified during production, the yearly photographs are your evidence and the modification is a negotiation. If the factory holds the programs and will not hand them over, you are negotiating for the digital half after the fact, which is why it belongs in the original tooling order.
Where this fits in an order. Tooling is the part of a programme that outlives the order, so it is worth ten minutes at the start: a separate invoice, an ownership letter naming the tool and its machine class, photographs with an asset tag, and the programs handed over with the steel. We write the tooling terms into the order before the tool is cut and keep the release procedure on file, so changing factory is a schedule question rather than a dispute. Send the product, the quantity and the destination, and the tooling plan comes back with the sourcing plan.
