7 Key Advantages of Plastic Medical Components
1. Lightweight Ergonomics
Medical-grade plastics reduce device weight by 40-60% vs. metal alternatives, decreasing user fatigue during prolonged procedures. Our gas-assist molded PA6+30%GF components maintain strength at 30% lighter weight.
2. Engineered Durability
Withstands 1,000+ autoclave cycles (134°C/273°F) without deformation
Impact resistance: 6 ft. drop-test certified for handheld devices
3. Cost-Effective Manufacturing
Family molds allow simultaneous production of related components
Overmolding eliminates assembly steps for multi-material devices
4. Sterilization Compatibility
Validated for all major methods:
| Method | Material Suitability |
|---|---|
| Autoclaving | PC, PPSU |
| Gamma Radiation | PEI, PEEK |
| EtO Gas | ABS+PC, PA6 |
5. Design Versatility
Micro-molding for components <0.5g with ±0.01mm tolerances
Living hinges in PP for single-piece assemblies
6. Clinical Transparency
Optical-grade PC with >92% light transmission for:
• IV fluid monitoring
• Endoscope lens housings
• AR/VR surgical navigation components
7. Chemical Resistance
Resists:
• Isopropyl alcohol (100% concentration)
• Hydrogen peroxide vapor
• Glutaraldehyde-based disinfectants
