Silicone Overmolding Half Mask PA Insert Mold

The silicone overmolding half mask PA insert mold is designed for producing high-precision thermoplastic and LSR components used in plastic half mask respirator assemblies. 

This mold adopts a 1-cavity hot runner system, which ensures stable material flow, efficient cycle times, and reduced waste compared to conventional runner designs. Each mold is manufactured with high-grade tool steel for durability and precision, offering a service life of over one million shots with proper maintenance. Various surface finishes including polished, textured, or matte can be applied to meet customer preferences. When paired with a silicone mould making machine, the mold enables stable silicone overmolding and efficient production for protective mask components.

Plastic and silicone components are critical elements in respirator mask assemblies, providing structural integrity, filter housing, and secure attachment features for protective masks. Manufactured using engineering-grade thermoplastics such as PC, ABS, or PA, these components deliver strength, durability, and chemical resistance for long-term use in industrial safety environments.
TYM’s silicone overmolding solutions ensure high dimensional accuracy, consistent quality, and seamless integration of plastic parts with silicone sealing components.

The hot runner system minimizes material waste and enhances part aesthetics by eliminating gate vestige and flow marks. Combined with silicone overmolding making machines, the resulting products are durable, lightweight, and compatible with a wide range of plastic half mask respirator designs for occupational safety and personal protective applications.
