At N.K. Rubber (M) Sdn. Bhd., we specialize in cutting-edge silicone injection molding technology to manufacture high-precision components that excel in flexibility, heat resistance, and extreme durability. Engineered for both complex prototyping and high-volume industrial production, our advanced capabilities safely fulfill the most rigorous manufacturing standards across the medical, automotive, electronics, and consumer appliances sectors.


Liquid Silicone Rubber (LSR) Injection Molding

Our state-of-the-art facility utilizes advanced automated Liquid Silicone Rubber (LSR) injection molding processes. By precisely dosing two-part liquid platinum-cured silicone systems into heated mold cavities, we achieve flash-free, dimensionally precise elastomeric parts that perform flawlessly in harsh operational environments.

Controlled Environment & Medical Grade Molding

To serve highly sensitive electronics and medical-grade device pipelines, we maintain a dedicated, controlled environment silicone molding layout. This infrastructure isolates automated raw material supply channels from exterior contaminants, guaranteeing clean-surface components that fully meet international safety protocols.

High-Volume Multi-Cavity Component Production

Deployed for ultimate supply chain cost efficiency, our custom silicone molding technology supports multi-cavity automated plate arrays. By integrating modern industrial pick-and-place robotics and cold-runner tool blocks, we accelerate cooling cycles and maximize output capacity without sacrificing strict tolerance limits.

Elastomeric Performance & Thermal Resilience

Our engineering support helps clients formulate custom silicone compounds designed to excel in challenging conditions. Every custom piece is optimized for maximum chemical resistance, long-term biocompatibility, and optimal high-temperature silicone properties, ensuring parts remain flexible from -50°C up to over +200°C.
