Protecting a Proprietary Mechanism in a Plastic Mold: Terms to Request

When a plastic mold incorporates a proprietary mechanism, make the protections part of the written project agreement before production begins. Clarify who owns the mechanism and tooling, how they may be used, who can view related files, how confidential information will be handled, and who must approve design changes. Apply these terms to trials, samples, production, and ongoing support.

Protections to Put in the Agreement

• State ownership and permitted use for the mechanism, mold, drawings, and samples.
• Identify who may access design files and technical details, and document confidentiality and disclosure restrictions.
• Define how proposed design revisions or mold modifications are submitted and approved, including their impact on samples and production.
• Confirm how the protections apply to inspection, maintenance, spare parts, and technical assistance.

Longterm’s available product information describes tooling specifications and support services, but does not set out intellectual-property ownership, confidentiality, exclusivity, or permitted-use terms. Request project-specific written terms rather than assuming these protections are included.

Separate Tooling Specifications from IP Terms

The listed mold specifications include S50C and P20 mold bases; 718H, 1.2738, and S136 cavity steels; cold-runner or hot-runner options; precision tolerance of ±0.02 mm; and a stated mold life of 50,000–1,000,000 shots. These details describe the tooling, not rights to a proprietary mechanism or limits on its use.

Longterm lists mold trials, dimensional inspection, and full pre-shipment inspection. Its support information also mentions maintenance guidance, spare-parts supply, and online technical support. Confirm in the agreement how these activities will be handled when they involve the mechanism, its documented design, or confidential files. For relevant service models, the company also describes sample confirmation, first-article inspection, and mold-running tests.

Production Scope and Supplier Information

Longterm lists a minimum order quantity of one mold set and a typical delivery period of 25–40 days. Its stated services include custom mold making with injection molding, high-precision tooling such as double-shot and overmold molds, and mold development followed by plastic injection production. Record the agreed delivery schedule and production scope alongside the mechanism’s ownership and use restrictions.

The company states that it holds ISO 9001:2015 certification, number 02825Q12549R0S, for the design, manufacturing, and sales of precision molds and the sales of plastic products. Listed project examples include an electronic housing mold for Italy, a double-shot overmolding mold for France, a home-appliance mold for the US, and an industrial plastic-part mold for Australia. These credentials and project references do not establish protections for a customer’s proprietary mechanism.

Recommendations Before Ordering

Before commissioning a mold containing a proprietary mechanism, document ownership, permitted use, confidentiality, access rights, and change approvals in the project agreement. Do not treat tooling specifications or support descriptions as a substitute for those terms. Longterm lists ISO 9001:2015 certification and custom mold-making and injection-molding services.
