Medical Grade Plastic Materials
Selecting the correct material is critical in medical injection molding. Medical components must often meet strict requirements for biocompatibility, chemical resistance, and sterilization compatibility.
Common materials used in medical injection molding include:
Polycarbonate (PC) – high strength and transparency
Polypropylene (PP) – widely used for disposable medical products
Polyethylene (PE) – chemical resistance and flexibility
POM (Polyoxymethylene) – high precision and low friction
Medical-grade ABS – good mechanical performance
TPE (Thermoplastic Elastomer) – soft-touch and sealing applications
Material selection depends on the specific medical application and product requirements.
Precision Medical Injection Mold Design
Medical parts often require extremely tight tolerances and high dimensional accuracy. Our mold engineers carefully design each mold to ensure optimal performance during production.
Key aspects of medical mold design include:
Mold flow analysis for balanced filling
Precision cavity and core machining
Optimized gate and runner systems
Efficient cooling channel design
Reliable part ejection systems
These design strategies help reduce defects such as warpage, sink marks, and short shots during production.
Clean Manufacturing Environment
Medical products often require a controlled manufacturing environment to ensure product safety and quality.
