• ISO 10993: This is the biological evaluation of medical device certification. It outlines regulations related to biocompatibility and safety of the material used. It helps manufacturers ensure that the materials used must be non-toxic, non-irritating, and allergen-free. ISO 10993 plays a major role for engineers and designers in the DMF phase, in material selection.

• ISO 14644 (Cleanroom Standards): Medical devices must be manufactured in a strict sterile environment with minimal human touch. ISO 14644 certification guarantees your sourced products are made in specialized cleanroom facilities, minimizing the risk of contamination. Essentially, medical injection molding requires an ISO Class 7 or ISO Class 8 cleanroom.

FDA Regulatory Guidelines

The Federal Drug Administration (FDA) enforces strict regulations for cleanliness and sterility of medical products. These regulations ensure products are safe and effective before entering the US market. FDA-compliant plastic injection molding China minimizes risks associated with foreign manufacturing processes. Key FDA guidelines include:

• Materials used in manufacturing injection mold tooling must be biocompatible.

• Rigorous testing and audits are done to evaluate the material for manufacturing. It ensures facilities operate under sterile conditions, relying on GMP (Good Manufacturing Practices).

• Chinese suppliers must provide clear Lot Traceability Certificates and Certificates of Analysis (CoA) confirming the resin contains zero regrind or unapproved additives unless explicitly authorized.
