Frequently Asked Questions (FAQs)

How do I evaluate the quality of a plastic mold factory?
Check for certifications like ISO 9001, request sample products, and review their portfolio. Ask about their quality control processes and visit the factory, if possible, to see their production methods firsthand.

What factors should I consider when choosing a supplier?
Consider their experience with your product type, pricing, lead times, communication skills, and after-sales support. Reliable suppliers should also offer technical assistance and be willing to accommodate small adjustments.

How can I verify a plastic mold manufacturer’s credentials?
Request business licenses, certifications, customer references, and evidence of past export or business history. Online reviews and third-party audits can also help verify credibility and reliability.

What information should I provide when requesting a quote?
Share detailed drawings or 3D models, material requirements, expected quantities, color specifications, and any desired finishing or tolerances. The more details you provide, the more accurate your quote will be.

Is it better to choose a local or overseas plastic mold factory?
Both have pros and cons: local factories offer easier communication and faster logistics, while overseas suppliers are often more cost-effective but may have longer lead times. Choose based on your priorities for cost, quality, and convenience.
