Technical Process
Step 01
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.
Step 02
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.
Step 03
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.
Step 04
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.
Step 05
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.
Step 06
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.
Step 07
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.

Frequently Asked Questions
What dimensional tolerance can be achieved for medical precision molds?
Our standard precision tolerance for medical injection molds is ±0.01mm. Utilizing high-speed CNC machining up to 42,000 RPM, precision Charmilles EDM, and slow-speed wire cutting, we guarantee strict dimensional compliance for intricate medical device components.
Which mold steel types are recommended for medical-grade applications?
We primarily utilize corrosion-resistant, high-polishability steels such as S136, 718H, P20, and SKD11 depending on part specifications, production volumes, and polymer corrosiveness. Full material traceability certificates are provided for every mold component.
How are medical molds tested and verified before delivery?
Mold trials are conducted in dedicated cleanroom-configured production environments. Molded samples undergo full dimensional inspection using CMM and vision measuring systems, accompanied by comprehensive First Article Inspection (FAI) reports and process parameter sheets.
What is the expected production lifespan of the precision molds?
Depending on the selected mold steel and maintenance regimen, our molds provide a shot life ranging from 100,000 to over 1,000,000+ cycles. We also provide long-term after-sales support, cavity insert replacements, and mold maintenance services.
What plastics and polymers can be processed with these molds?
Our molds are engineered to process PC, PP, PA66, and a wide variety of medical-grade engineering plastics. DFM analysis and Moldflow simulations are conducted early in the design stage to accommodate unique shrinkage and flow characteristics.
What maximum mold sizes and clamping capacities can you support?
We manufacture molds up to 3,200 × 1,800 × 1,600mm. Our facility is equipped with over 150 injection molding machines ranging from 45T to 1600T, enabling validation and pilot production for components of all sizes.
