What a mold is, and why ownership matters
A mold is the tool that shapes a model: a metal or resin form, machined from an approved prototype, into which material is cast, injected, or pressed, figure by figure, until the order quantity is made. The mold decides the model's shape, detail, and consistency, because every figure from that mold shares its shape, and because a mold made well produces consistent figures, while a mold made poorly produces inconsistent ones. Ownership of the mold decides who controls that tool: who may use it, who must maintain it, who stores it, and what happens to it when production ends, or when the relationship between buyer and manufacturer ends, and because those decisions affect the buyer's design, its exclusivity, and its future, ownership matters as much as the mold itself.
A buyer who does not confirm mold ownership has not confirmed who controls the tool that makes their products, and a buyer who pays without that confirmation has paid for an order whose design protection is unknown, which is a design at risk, however good its production appears. Confirm ownership, in writing, before payment, because ownership confirmed before payment is ownership that can be relied on, while ownership assumed, or left unstated, is ownership that will be decided by whoever holds the mold, when it matters, which may not be the buyer.
The Car Models family example, marked
For the car models family, the representative description states that everything related will be used for your company only, as stated on the official site's representative page for that family. That statement is a family example, marked as such, for the car models family only, and it must not be read as a site-wide mold rule, because each family's mold terms are confirmed per family, in the inquiry, and because a mold term stated for one family may not apply to another, however similar the families appear. For the motorcycle, space and airplane, and cartoon character families, the representative descriptions state that molds will be your property, as stated on their respective representative pages, and those statements are likewise family examples, each for its own family.
A buyer who wants another family should not assume its mold terms from these examples, because families differ, and because a mold term that fits one family may not fit another, and a buyer who reads a family example as a site-wide rule will order on a term that does not apply to their design, and will face correction, delay, or dispute, when the order arrives, while a buyer who confirms mold terms for their design, in writing, before payment, will receive the terms that design carries. Confirm mold terms per design, not per site, because mold terms, like every commercial term, are per-design, and because a per-design confirmation is a confirmation that can be relied on.
What ownership should cover
Mold ownership, confirmed properly, should cover: who owns the mold, in name, so there is no doubt; what it may be used for — the buyer's products only, or any purpose the owner allows — so there is no reuse beyond agreement; where it is stored, so the buyer knows where their tool is; who maintains it, and at whose cost, so it stays usable; what happens when production ends — stored, returned, or destroyed — so the buyer knows its fate; and what happens if the relationship ends — returned to the buyer, or retained by the manufacturer — so the buyer knows whether their design's tool survives the relationship. Each answer changes what ownership is worth, and a mold term that answers some but not others leaves the unanswered to be decided later, when it matters, by whoever holds the mold.
Ask for all six answers, in writing, before payment, because a mold term that answers all six is a mold term that can be relied on, while a mold term that answers only ownership — 'the mold is yours' — without use, storage, maintenance, end-of-production, and end-of-relationship, is a mold term that leaves the most important questions unanswered, and because a buyer who accepts a partial mold term has accepted a partial protection, which will fail at the unanswered question, when it arises, however well the answered questions were handled.
Use restrictions: your products only
The most important mold restriction is use: a mold that belongs to the buyer should be used for the buyer's products only, and not for another buyer's products, for the manufacturer's own products, or for any purpose the buyer has not agreed to, because the mold embodies the buyer's design, and because use beyond agreement dilutes the design's exclusivity, competes with the buyer, and betrays the trust on which custom manufacturing depends. Confirm the use restriction, in writing, with its wording — 'for your products only', or equivalent — because a restriction stated vaguely, or not at all, is a restriction that cannot be enforced, however well intended, and because a manufacturer who reuses a mold beyond agreement, even innocently, harms the buyer whose design it is.
A buyer who values exclusivity should insist on a use restriction, and should check it, because a design produced exclusively is a design whose market is the buyer's alone, while a design produced for others is a design whose market is shared, however exclusively the buyer believed it to be. Check use restrictions before payment, in writing, because a restriction confirmed before payment is a restriction that can be relied on, while a restriction assumed, or left unstated, is a restriction that will be decided by whoever holds the mold, when reuse is proposed, which may not be the buyer.
Storage, maintenance, and end of production
Storage and maintenance decide whether a mold remains usable: a mold stored poorly rusts, warps, or degrades, and a mold maintained poorly produces figures with flashing, warping, or missing detail, however good it was when made, so a buyer should confirm where the mold is stored, in what conditions, who maintains it, at whose cost, and how often, because a mold stored and maintained well will produce consistent figures for years, while a mold stored and maintained poorly will fail, when it is next needed, at the cost of remaking it, or losing the design's production entirely.
End of production decides the mold's fate: stored for future orders, returned to the buyer, or destroyed, each with its own implications, because a mold stored for future orders allows reorders without remaking, a mold returned to the buyer gives the buyer control, and a mold destroyed ends the design's production definitively, and because a buyer who does not confirm the mold's end-of-production fate will discover it when production ends, when the options have narrowed, and when the mold may already have been stored poorly, returned late, or destroyed without agreement. Confirm storage, maintenance, and end-of-production fate, in writing, before payment.
End of relationship: the hardest case
End of relationship is the hardest mold case, because a relationship that ends — by completion, by disagreement, or by insolvency — leaves the mold in someone's hands, and the hands that hold it decide its fate, unless the terms decided it in advance. Confirm, in writing, before payment, what happens to the mold if the relationship ends: returned to the buyer, within a stated time, at whose cost, in what condition, or retained by the manufacturer, with what use restrictions, because a mold term that does not cover end-of-relationship is a mold term that will be decided by dispute, when the relationship ends, at cost, delay, and effort, and because a buyer who confirms it early has protected their design, while a buyer who leaves it has left their design's tool to chance.
A buyer who values their design should treat end-of-relationship mold terms as essential, not optional, because relationships end, even good ones, by completion, by change, or by circumstance, and because a design whose mold terms survive its relationship is a design that can be produced again, by another manufacturer, while a design whose mold terms die with its relationship is a design that must be remade, at the cost of a new mold, a new prototype, and a new timeline, however good the original production was. Confirm end-of-relationship terms early, because early confirmation is cheap, while late dispute is dear.
Mold costs: who pays, and for what
Mold costs decide who pays for the tool, and for what: the mold's making, its maintenance, its storage, and its return, each with a cost, and each with a payer, because a mold cost that is not agreed will be charged somewhere, sometime, to someone, and because a buyer who does not agree mold costs early will face them later, as an unexpected charge, a delayed order, or a withheld mold, when the cost is finally stated. Ask, in writing, before payment: who pays for making the mold, who pays for maintaining it, who pays for storing it, and who pays for returning it, because each answer changes the order's total cost, and because a mold cost agreed early is a cost that can be planned on, while a mold cost agreed late is a cost that surprises.
Mold costs also affect minimums, because a mold's cost must be spread across the order quantity, and because a small order spread over a dear mold costs more per unit than a large order spread over the same mold, so a buyer who wants a small order should ask how the mold cost affects the unit price, and whether a smaller mold, a simpler mold, or a shared process could reduce it, rather than assuming that mold cost is fixed, regardless of quantity, because mold cost per unit falls as quantity rises, and because a buyer who orders a small quantity without understanding mold cost will pay more per unit than expected, however reasonable the mold cost itself appears.
What to confirm, before ordering
Before payment, confirm the mold ownership terms for your design, in writing, with their meaning: who owns the mold, what it may be used for, where it is stored, who maintains it, what happens when production ends, and what happens if the relationship ends, plus who pays for making, maintaining, storing, and returning it. Name the design, the material, the scale, the quantity, and the market, so the supplier can confirm for your design, and so the confirmation you receive is the confirmation you can rely on, and so the payment you make is a payment for an order whose design is protected, not merely produced.
A buyer who confirms mold ownership fully — owner, use, storage, maintenance, end-of-production, end-of-relationship, and costs — in writing, before payment, has protected their design, not just ordered it, and a buyer who confirms it partially, or not at all, has ordered a design whose tool is unprotected, however good its production appears. Protect the tool, because the tool makes the design, and because a design whose tool is protected is a design that can be produced again, while a design whose tool is not is a design at risk, however good its first order was.
