Question 1

What information do I need to provide to get a quote for custom plastic manufacturing?

Accepted Answer

At minimum, a custom plastic manufacturer needs: the product design (3D CAD files in STEP or IGES format are standard; 2D drawings or physical samples can substitute for initial pricing but are less precise), the material specification (resin type, grade, colour), the production quantity (annual volume and order quantity), the required tolerances (for engineering parts), any surface finish requirements (texture, gloss, colour matching), and the target market (required certifications, food-contact compliance, etc.). For tooling quotes, the CAD model is required. Providing this information upfront avoids multiple rounds of clarification and speeds up the quotation process.

Question 2

Who owns the injection mould tooling?

Accepted Answer

Tooling ownership is a contractual matter negotiated between the buyer and manufacturer. Common arrangements: buyer-owned tooling — the buyer pays for the mould, owns it, and can transfer it to another manufacturer; this is the standard arrangement for established buyers sourcing at volume. Manufacturer-owned tooling — the manufacturer amortises the tooling cost into the per-part price over a committed volume; the mould remains the manufacturer's property. Buyers planning to source from a single manufacturer long-term may find amortised tooling easier to manage; buyers who want sourcing flexibility should insist on buyer-owned tooling with a written agreement confirming ownership, storage, and transfer terms. For buyer-owned tooling placed at a Chinese manufacturer, include the tooling ownership terms in the purchase agreement and retain copies of the tooling design and technical documentation.

Question 3

How do I protect my product design IP when working with a custom plastic manufacturer?

Accepted Answer

Register IP in relevant jurisdictions before disclosing designs — a registered design patent or utility patent in your target market provides meaningful protection. Use an NDA (non-disclosure agreement) before sharing designs — ensure it is governed by a jurisdiction where it is enforceable. For Chinese manufacturers, a Chinese-language NDA enforceable in Chinese courts provides more practical protection than a foreign-law NDA. Consider design fragmentation: disclose only the parts of the design necessary for the manufacturer's scope — avoid sharing the complete product concept if a subset suffices. Work with established, verified manufacturers with a reputation to protect — large, export-focused factories are generally lower IP risk than small, undocumented workshops.
