FAQ
Q: What medical standards do your raw materials meet?
A: All utilized polymers comply with USP Class VI, ISO 10993 biocompatibility requirements, and FDA food/medical contact regulations where applicable. Full material certs are provided with every lot.
Q: What is your typical tooling lead time?
A: Standard prototype tooling takes 2 to 3 weeks. Production-grade multi-cavity steel molds range from 4 to 7 weeks depending on part complexity and hot runner requirements.
Q: Can you handle mold transfer projects from existing suppliers?
A: Yes. Our engineering team manages full tool inspections, dimensional audits, first article inspection (FAI) reports, and parameter matching to ensure seamless production continuity.
Q: What sterilization methods are compatible with your molded parts?
A: Our materials and processes support standard medical sterilization methods including EtO (Ethylene Oxide), gamma irradiation, electron beam, and autoclave (material-dependent).
