When looking to purchase PET preform or bumper moulds for your production needs, Chinese mould makers offer high quality options at very competitive prices compared to domestic manufacturers. However, navigating the numerous suppliers in China can be an overwhelming task for first-time buyers.
This comprehensive guide provides key considerations and actionable tips when procuring PET preform and bumper moulds from China. Equipped with this information, you can efficiently source excellent moulds tailored to your requirements from reputed and certified Chinese companies.
Clear Out Your Mould Specifications
Having a well-defined set of specifications is vital before requesting quotations from Chinese mould makers. Key details include:
- Part dimensions: Provide detailed drawings of your target PET preform or bumper part design. This aids the manufacturer in properly sizing the mould.
- Material: PET, PP, ABS etc. This impacts mould materials and processing parameters.
- Annual volume: Higher volumes warrant more complex moulds with hot runner systems.
- Precision requirements: Tolerance grades should be established upfront.
- Surface finish: Specifications for polish, texture etc.
Prepare and share as much technical specifications as possible with potential suppliers when sourcing your PET preform or bumper mould. This allows them to provide an accurate quote and delivery timeline.
Perform Due Diligence on Shortlisted Suppliers
Once you have decided to order moulds from China and received several quotes, do your research before selecting a supplier:
- Check certifications & compliance: Reputed mould makers have ISO 9001 and 14001 certificates along with export compliance like ROHS.
- Visit company premises if possible: An on-site tour gives the best sense of production capabilities.
- Ask for customer references: Speaking with prior buyers is invaluable for verifying quality and service claims.
- Review sample moulds: Assessing a similar pre-existing mould firsthand is ideal. Failing that, high resolution images also work.
- Check engineering expertise: Look into the supplier’s mould design skills and past work, especially for complex moulds.
Invest time upfront vetting and choosing your Chinese PET preform or bumper mould partner through careful analysis – this pays rich dividends later with superior moulds delivered on schedule.
Clearly Map Out “Mould Development Journey”
Chinese manufacturers use standardized mould development roadmaps. Having clarity on each milestone upfront ensures alignment and accountability:
- Kick-off meeting: Requirements finalization
- Engineering design: 3D model approval
- Mould flow analysis: Optimization of runner systems
- Mould manufacturing: Step-by-step project updates
- Sampling & adjustments: Fine-tuning of mould
- Final mould delivery: Quality assurance testing
Get granular! Detail out target dates for first article inspection, design changes based on samples, final inspection prior to shipment etc. Account for factors like Chinese New Year holidays in the timeline.
Leverage Escrow Payments for Better Control
To balance buyer-supplier interests, use an escrow PET preform or bumper mould payment system:
- 30% advance for raw materials and processing
- 60% released post-sampling approval
- 10% after final delivery and acceptance
Escrow payments give buyers leverage in case of delays or quality issues, while providing working capital to the mould maker. For simpler or lower cost moulds, 100% payment on delivery also works.
Secure Mould IP Rights Upfront
For proprietary PET preform or bumper moulds with special features, the design IP must contractually reside with the buyer not the Chinese manufacturer. Common agreement clauses include:
- NNN mould design is the confidential information of the buyer
- Maker cannot replicate mould or sell to 3rd parties without consent
- Open-source CAD files cannot be publicly shared
Chinese law supports such IP protection clauses. Acting early avoids issues later – make sure your mould IP is air-tight!
Perform Final Mould Inspection Before Shipping
Before your finished PET preform or bumper mould gets boxed up and dispatched from China, conduct one last rigorous quality check:
- Dimensional accuracy: Confirm adherence to 3D model measurements
- Surface finish inspection: Defects like scratches, sinks etc.
- Mould marking: Rating plates, lifter locations etc.
- Split line verification: No mismatch post assembly
- Process capability: Test runs validating performance
Appointing an in-country 3rd party inspector to supplement your own checks is wise for million+ dollar aerospace or medical moulds. This gives total assurance before shipping.

Be Proactive in Resolving Production Issues
Despite the best made plans, real-world manufacturing issues may still crop up with your China moulds:
- Long debug times affecting output

- Daily check-in calls/messages
- Prompt feedback on samples
- Quick approvals for design tweaks
