Technical FAQ

 

 

Q: Which medical-grade resins are best suited for specific sterilization methods?

A: COC / COP: Excellent optical clarity; ideal for Gamma and EtO sterilization; prone to degradation under high-heat autoclaving.
PEEK: Exceptional mechanical strength and thermal stability; withstands repeated autoclave cycles and harsh chemical sterilization.
Polycarbonate (PC): Good impact resistance and transparency; compatible with EtO and Gamma (slight yellowing can occur with high-dose Gamma).
Polypropylene (PP): Excellent chemical resistance; standard choice for single-use disposable fluid pathways sterilized by EtO or Gamma.

Q: Do you provide validation documentation for regulatory submissions?

A: Yes. We generate comprehensive documentation packages including dimensional inspection reports, material certificates, process parameters, and supporting data for IQ/OQ/PQ protocols.

Q: What is the typical lead time for custom mold tooling?

A: Standard prototype tooling ranges from 2 to 3 weeks. Production-grade multi-cavity steel molds typically require 4 to 7 weeks depending on part complexity, cavity count, and hot runner integration.

Q: How do you control particulate and biological contamination during molding? 

A: Production takes place inside ISO Class 7 and Class 8 cleanrooms. Personnel wear lint-free cleanroom garments, automated material loaders prevent ambient exposure, and finished parts are immediately sealed in anti-static medical-grade poly bags.
