Securing Primary Tooling Rights in Chinese Subcontracting Manufacturing Contracts
Securing primary tooling rights in China requires standalone title contracts, clear steel verification, non-lien waivers, and physical shop-floor audits.
Mold Trial Audit
Meaning
Systematic inspections conducted during the testing phase of a new injection mold verify that the equipment meets all technical and quality specifications. A mold trial audit involves observing the performance of the tool under actual production conditions to identify defects or areas for improvement. Engineers check the cycle times and the dimensional accuracy of the parts produced during these test runs.
This process ensures that the mold is ready for mass production before the final payment is released to the toolmaker.
Testing Protocol
Procedures for the trial include the measurement of temperatures and pressures at various stages of the molding cycle. During a mold trial audit, the technician records any issues such as flashing or short shots that indicate a problem with the tool design. This data is used to adjust the settings and optimize the performance of the equipment for the specific material being used.
Quality Verification
Samples taken from the trial are sent to a laboratory for detailed analysis and comparison with the original blueprints. The mold trial audit report documents these findings and provides a list of necessary modifications for the toolmaker to address. This verification step is necessary for maintaining the quality of the finished product and avoiding costly reworks later in the production lifecycle.
Final Approval
Acceptance of the tool occurs only after the manufacturer demonstrates that it can produce a consistent run of parts within the specified tolerances. By conducting a thorough mold trial audit, the buyer reduces the risk of encountering production delays once the mold is transferred to the main factory. This audit functions as the final gateway in the development process and confirms that the capital investment has resulted in a functional and reliable asset.
The formal sign off provides the legal basis for the transfer of ownership from the tool shop to the production facility.
