Detail Information

Introduction:

Liquid Silicone Rubber (LSR) Injection Molding is one of the most advanced manufacturing processes for producing high-precision, high-performance silicone rubber components. As an experienced silicone manufacturer, Siliconeplus.net specializes in custom LSR injection molding solutions designed to meet the strict requirements of medical, food, automotive, electronics, and industrial applications.

LSR injection molding uses two-part platinum-cured liquid silicone rubber that is automatically metered, mixed, and injected into closed molds.

This process enables exceptional dimensional accuracy, excellent repeatability, and clean production environments, making it ideal for applications requiring tight tolerances and consistent quality. Compared with traditional compression or transfer molding, LSR molding offers higher efficiency, lower material waste, and superior surface finish.

One of the key advantages of LSR silicone components is their outstanding material performance.

Liquid silicone rubber provides excellent thermal stability, maintaining mechanical properties across a wide temperature range from -60°C to over 230°C. It also offers superior chemical resistance, UV stability, and long-term elasticity, ensuring reliable performance even in harsh operating conditions. These properties make LSR components suitable for repeated sterilization, high-temperature processing, and outdoor or chemical-exposed environments.

For B2B customers, product safety and compliance are critical decision factors. Siliconeplus utilizes FDA- and LFGB-compliant raw materials and follows strict quality control systems to ensure every LSR silicone part meets international standards. Our manufacturing process supports cleanroom production, burr-free molding, and seamless overmolding on plastic or metal substrates, significantly reducing assembly steps and improving overall product reliability.

Customization is at the core of our LSR injection molding services. From mold design and material selection to prototyping and mass production, our engineering team works closely with customers to optimize part geometry, hardness, sealing performance, and integration with other components. Whether you require medical-grade silicone seals, food-contact silicone parts, waterproof electronic enclosures, or automotive silicone components, we deliver scalable OEM and ODM solutions tailored to your application needs.
