When it comes to precision molding in the medical and electronics industries, choosing the right silicone matters. Liquid Silicone Rubber (LSR) is rapidly gaining popularity due to its ability to handle complex, high-volume production with consistency.
Key Molding Methods for LSR:
🔹 Ordinary Molding Machine
- Manual process, low cost, minimal waste
- No runners required, simple mold structure (2–3 layers)
- Ideal for parts like SIM card trays, watch gaskets, and electric toothbrush seals
🔹 Vertical Liquid Silicone Injection Molding
- Best for overmolding/secondary molding
- Supports large parts and complex inserts (metal, ABS, PA, PPSU)
- Used in medical devices, maternal care, and kitchen products (e.g., silicone toothbrush, baby spoons)
🔹 Horizontal Liquid Silicone Injection Molding
- Supports full automation and high-precision control
- Automatic demolding boosts efficiency
- Ideal for liquid silicone breast pump, straws, sippy cups, soothers, teethers and so on.
✅ Compared to solid silicone, LSR offers faster cycle times, higher consistency, and better scalability for modern manufacturing.
