# Custom Liquid Silicone Rubber Flexible Contact

Custom Liquid Silicone Rubber (LSR) flexible contacts are precision-molded elastic connecting components manufactured by 橡楚（湖北）橡胶有限公司, designed to deliver reliable electrical insulation, mechanical buffering, and consistent contact performance across dynamic operating conditions. As a specialized LSR product tailored to unique application requirements, these flexible contacts leverage the inherent advantages of medical-grade and industrial-grade liquid silicone rubber to meet strict tolerance, durability, and environmental resistance demands.
Unlike standard off-the-shelf contact components, our custom LSR flexible contacts are engineered to match your exact dimensional, hardness, and performance specifications. Whether you need small-batch prototype parts or high-volume production runs, we adapt our compression and injection molding processes to deliver components that integrate seamlessly into your end product. All our flexible contacts are produced with low-volatility, impurity-free LSR raw materials, ensuring consistent performance even in prolonged exposure to extreme temperatures, moisture, and UV radiation.
At 橡楚（湖北）橡胶有限公司, located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, we focus exclusively on LSR product development and manufacturing, allowing us to deliver custom flexible contacts with shorter lead times and more consistent quality than general rubber manufacturers.

Our custom LSR flexible contacts are manufactured from 100% pure addition-cure liquid silicone rubber, with the following core material properties:
Physical performance can be adjusted based on customer requirements; standard specifications are as follows:
For custom molded LSR flexible contacts:

Unlike rigid contact components or generic rubber contacts, our LSR flexible contacts can be formulated to achieve a wide range of hardness from ultra-soft 10 Shore A to moderately firm 50 Shore A. This allows you to match the exact deflection force and recovery rate required for your application, eliminating the need for design compromises associated with standard parts. The platinum-cure LSR maintains consistent elasticity over millions of compression cycles, with minimal permanent compression set that prevents contact failure over the service life of your product.
LSR inherently retains its mechanical and electrical properties across a far wider temperature range than organic rubbers. Our flexible contacts remain flexible at -40°C and do not soften or degrade at continuous temperatures up to 200°C, making them suitable for both extreme cold industrial environments and high-temperature consumer applications. The high volume resistivity and consistent dielectric strength provide reliable electrical insulation, preventing arcing and short circuits in power and electronic applications. LSR also resists UV degradation and water absorption, making it ideal for outdoor and humid operating environments.
Our injection molding process for LSR supports tight tolerance manufacturing for complex custom geometries, including undercuts, thin walls, integrated mounting features, and embedded inserts (such as metal backing plates or conductive cores). We can produce smooth surface finishes without additional post-processing, reducing your assembly costs and ensuring consistent fit when integrated into your end product.
We use high-purity LSR raw materials with no residual harmful additives, resulting in flexible contacts that meet low-volatility and low-leaching requirements. Food-grade and medical-grade material options are available for applications that come into contact with food or biological tissue, with raw material test reports provided for all custom orders.

The appropriate hardness depends on your required contact force and deflection:
We produce flexible contacts to your exact 2D or 3D design specifications. We support modifications to existing designs for prototyping, and can adjust dimensions and tolerances to match your assembly requirements. For components requiring embedded metal or plastic inserts, please specify insert material and dimensions in your design file.
We offer three standard material grades to match different application requirements:

橡楚（湖北）橡胶有限公司 operates a quality management system certified to ISO 9001, with systematic quality control implemented across every stage of production, from raw material incoming inspection to final product outgoing testing. Each batch of custom LSR flexible contacts undergoes dimensional verification, visual inspection, and performance sampling testing to ensure compliance with your specifications and agreed quality standards.
We provide full material test reports and certification documentation with every order. If you require adjustments to performance or dimensions after prototype evaluation, our engineering team will work with you to refine the design and manufacturing process to meet your requirements.
