Molding Process
- LSR Injection Molding: High-precision molding process for mass production of liquid silicone rubber parts.
- LSR Transfer Molding: Suitable for small-to-medium volume silicone parts, inserts, and complex geometries.
- LSR Overmolding: Molds silicone over plastic, metal, glass, or other substrates for sealing and soft-touch functions.
- Insert Molding: Places metal, plastic, or electronic inserts into the mold before silicone molding.
- 2K / Multi-Shot LSR Molding: Automated multi-shot process for LSR + plastic, LSR + LSR, or multi-color silicone parts.
- Prototype and Small Batch Molding: Flexible tooling and molding support for samples, testing, and low-volume production.
- Selected Compression Molding: Used for selected silicone parts with simple structures or lower-volume production needs.
