The 16-cavity automotive wire harness seal mold is designed for high-efficiency LSR injection molding of precision silicone seals used in automotive electrical systems. It adopts a cold runner system to achieve flash-free molding and eliminate raw material waste. Each cavity is engineered for long service life, ensuring stable output with minimal maintenance.
This mold can be perfectly integrated with the TYM-W555 injection molding machine and the robotic arm, enabling automatic demolding and part processing. As a result, a fully automated production line can be established.
Automotive wire harness seals are critical components for ensuring reliable sealing and protection of vehicle electrical connectors. They prevent dust, moisture, and contaminants from entering the harness system, thereby safeguarding vehicle performance and durability. Manufactured from high-quality liquid silicone rubber (LSR), these seals offer outstanding elasticity, weather resistance, and thermal stability, with operating temperature ranges from –50 °C to +200 °C.
TYM’s wire harness seal mold solutions provide precision molding of multi-cavity silicone seals, supporting high-volume LSR injection molding with consistent quality.
The cold runner design eliminates waste and lowers overall production costs. Combined with automation compatibility and smooth integration with modern injection molding machines, this mold is an ideal choice for Tier 1 and Tier 2 automotive suppliers seeking efficiency and long-term reliability.
