Frequently Asked Questions (FAQs) for B2B Buyers of medical injection molding

  1. How can I effectively vet and select a qualified medical injection molding supplier internationally?
    When vetting international suppliers, prioritize those with documented experience in medical device manufacturing and a proven export track record to your region. Request references, audit reports, and evidence of compliance with international standards like ISO 13485 and FDA or CE certifications. Evaluate their production capacity, quality control systems, and ability to meet your regulatory requirements. If possible, conduct virtual or on-site audits and ask about language capabilities, after-sales support, and responsiveness to ensure seamless cross-border collaboration.

  2. Is it possible to customize medical injection molded parts to local market specifications or regulatory requirements?
    Yes, reputable suppliers offer extensive customization options—from selecting biocompatible materials to modifying product designs and packaging for regional compliance (e.g., MDR in Europe or ANVISA in Brazil). Share your technical drawings, compliance needs, and local standards early in the process. Insist on design for manufacturability (DFM) reviews and demand prototypes or samples for validation before mass production to ensure that final products align perfectly with both regulatory obligations and user preferences.

  3. What are typical minimum order quantities (MOQ), lead times, and payment terms for medical injection molding orders?
    MOQs vary widely based on mold complexity and part size, but for medical applications, they typically range from 1,000 to 10,000 units.
