Adapting to High-End Needs of Smart Wearables and New Energy
Keywords: Precision Silicone Rubber Accessories, Liquid Silicone Rubber (LSR) Injection Molding, Dimensional Accuracy, Extreme Environment Adaptability
Core Summary: On March 29, 2026, Zhongshan Dongsheng Zhenxiong Silicone Rubber Products Factory launched a new generation of precision silicone rubber accessories. Adopting Liquid Silicone Rubber (LSR) injection molding process, it greatly improves product
dimensional accuracy and extreme environment adaptability, and has successfully supported high-end fields such as smart wearables and new energy vehicles.
With the development of terminal equipment towards miniaturization and integration, the requirements for dimensional accuracy and structural complexity of silicone rubber accessories are becoming increasingly strict. The precision silicone products launched by Zhenxiong Silicone Rubber this time target scenarios such as smart door lock fingerprint recognition modules and 3D face recognition structured light modules. By introducing high-precision multi-cavity molds and CAD/CAE simulation analysis technology, and optimizing product structure design, the flatness of the produced silicone pads can be controlled within ±0.05mm, and the key dimension CPK value is stable above 1.33, ensuring stable contact with sensors and improving equipment recognition accuracy and speed.
For extreme environments such as outdoor lighting and automobile engine compartments, the special waterproof ring material developed by the enterprise has a compression set rate of less than 15% after 1500 hours of ultraviolet accelerated aging and high-low temperature cycle test from -40℃ to 120℃, which is better than the industry average. In addition, the products have passed biocompatibility, non-toxic migration and other tests, and can be adapted to sensitive scenarios such as medical treatment and food contact, realizing the upgrade from "general parts" to "high-performance functional parts".
