Frequently Asked Questions (FAQs)

How do I evaluate the quality of an injection mold manufacturer?
Start by checking certifications (such as ISO 9001), inspecting sample products, and reviewing client testimonials. Ask about their quality control processes and whether they conduct mold trials and product testing before delivery.

What information should I provide to get an accurate quotation?
Send detailed drawings or 3D models, specify material requirements, estimated production volume, tolerances, and any special surface finishes. The more specifics you provide, the more precise your quote will be.

What factors should I consider when comparing different suppliers?
Look at manufacturing capabilities, experience with your product type, turnaround times, communication responsiveness, pricing, and after-sales support. Don’t forget to factor in logistics and shipping costs if they are overseas.

Can I visit the factory before making a decision?
Absolutely! Reputable manufacturers will welcome visits or provide virtual tours. Factory visits let you assess their equipment, workforce skill, and management practices, ensuring transparency and peace of mind.

What are common red flags to watch for when selecting a manufacturer?
Be cautious if suppliers are reluctant to share company details, give vague answers, have poor communication, or provide inconsistent quotations. Lack of quality documentation or client references is also a warning sign.
