Technical Process
1
Inquiry & Medical Requirements Review
Customer submits medical component drawings with precision and material specifications. Jinlong's team evaluates dimensional requirements, material compatibility for medical-grade plastics, and cleanroom production requirements before providing a quotation within 3 business days.
2
Medical-Grade DFM Analysis
Jinlong conducts a medical-focused DFM analysis — reviewing precision dimensional requirements, wall thickness control for thin-wall sections, material flow characteristics for medical-grade engineering plastics, and ejection strategy for precision components. Emphasis on sink mark prevention and dimensional stability.
3
Precision Mold Design for Medical Applications
Mold designs developed using SolidWorks, Pro/ENGINEER, UG, or CATIA with medical-grade precision standards. Special attention to cavity insert flatness for dimensional consistency, polish requirements for medical surfaces, and ejection system design for precision components. Designs submitted for customer approval.
4
Precision Machining with Quality Verification
Molds manufactured using high-speed CNC (up to 42,000 RPM) for precision cavity surfaces, Charmilles EDM for intricate medical component features, and slow-speed wire-cut for core/cavity inserts. Each machined component undergoes in-process dimensional verification before assembly.
5
Cleanroom-Configured Trial & Inspection
Mold assembled and trials conducted in Jinlong's dedicated production areas configured for cleanroom-compatible medical molding. Samples inspected on CMM and vision measuring system with full dimensional documentation. Material certificates and process parameters documented for medical compliance.
6
Medical Documentation & Approval
Complete documentation package prepared including FAI report with CMM measurement data, material certificates for mold steels and production materials, process parameter sheets, and dimensional traceability records. Samples and documentation submitted for customer approval.
7
Medical After-Sales Support
Ongoing support for precision maintenance, cavity insert replacements, and engineering modifications throughout the mold's service life in medical production applications.
