Design Notes for Production
- The product is produced through a precision two-step injection molding process:
- PC Injection Molding Medical-grade polycarbonate is molded into the structural base, forming the rigid housing and internal flow channels.
- LSR Overmolding Liquid silicone rubber is injected onto the PC substrate, forming soft sealing structures and functional interfaces.
- Permanent Bonding Formation Under controlled temperature and pressure, LSR chemically or mechanically bonds with PC, forming a durable integrated structure.
- Silicone rubber has natural chemical inertness, making adhesion to PC challenging. This is solved through:
- Self-bonding medical-grade LSR formulations
FAQ for Engineering Buyers
What is the benefit of LSR overmolding compared to traditional assembly?
LSR overmolding eliminates separate sealing components such as O-rings, reducing leakage risk and improving long-term stability.
Is the product suitable for repeated sterilization?
Yes, it is designed for repeated autoclave sterilization between 121°C and 134°C without performance degradation.
Does the silicone become hard or degrade over time?
Medical-grade LSR maintains elasticity and mechanical stability under long-term use.
