# Liquid Silicone Rubber Overmolded Housing Part
Product of 橡楚(湖北)橡胶有限公司
---
Liquid Silicone Rubber (LSR) overmolded housing parts are custom-engineered protective components that combine rigid substrate materials (such as engineering plastics, aluminum, or stainless steel) with biocompatible liquid silicone rubber via precision injection overmolding. As a professional manufacturer of LSR products based in 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, 橡楚(湖北)橡胶有限公司 produces these overmolded housing parts to deliver enhanced protection, ergonomic comfort, and functional performance for end-use products across industrial, consumer, medical, and electronic sectors.
Our LSR overmolded housing parts leverage the inherent advantages of LSR material: excellent thermal stability, chemical resistance, electrical insulation, and soft tactile feel, while the rigid core substrate maintains structural rigidity and dimensional stability required for load-bearing or enclosure applications. Unlike separate assembly of rigid housings and silicone gaskets or covers, our integrated overmolding process eliminates gaps between materials, reduces assembly steps for our customers, and improves overall sealing performance. All our production follows ISO 9001 quality management standards, with strict process control from raw material inspection to final product testing to ensure consistent quality for every batch.
We support full custom manufacturing based on customer 2D/3D drawings and functional requirements, with flexible production capacity that accommodates both low-volume prototype trials and mass production orders. Whether you need a water-sealed housing for outdoor electronics, a non-slip grip housing for handheld medical devices, or a impact-resistant housing for industrial sensors, our LSR overmolding solution can be tailored to meet your specific application needs.

Our LSR overmolded housing parts use high-purity raw platinum-catalyzed liquid silicone rubber as standard, with the following core material properties:
Finished overmolded housing parts are tested to meet the following physical performance requirements (adjustable per customer requirements):
Our standard injection overmolding process is controlled to the following parameters to ensure consistent product quality:

Compared to traditional assembly methods that combine rigid housings with separate silicone gaskets or covers, our overmolded process forms a seamless, gap-free bond between the LSR outer layer and rigid inner substrate. This eliminates leak paths that can form with assembled components, delivering consistent IP65 to IP67 level water and dust protection with proper design. The rigid core maintains the required dimensional stability and load-bearing capacity for the housing, while the LSR layer adds protective functions.
We can adjust the Shore hardness of the LSR layer to meet specific touch and grip requirements: soft 10-20 Shore A LSR delivers comfortable, non-slip grip for handheld devices, while harder 50-70 Shore A LSR provides enhanced abrasion resistance for high-wear applications. The LSR material also provides excellent shock and vibration absorption, reducing impact damage to sensitive internal components during use or accidental drops.
Our LSR material retains its flexibility and mechanical properties after long-term exposure to extreme temperatures, UV radiation, and humid environments, with no cracking, hardening, or degradation that plagues many organic elastomers. This makes our overmolded housing parts ideal for long-term outdoor or industrial use, reducing replacement and maintenance costs for end products.
As a dedicated LSR product manufacturer, we have in-house mold design and manufacturing capabilities, which reduces lead times for custom tooling. The overmolding process combines multiple components into a single part, reducing your assembly labor and component inventory costs. We can accommodate production volumes ranging from 100 prototype units to 100,000+ mass production units, with flexible order arrangements to match your project timeline.

Liquid silicone rubber overmolded housing parts are used across a wide range of industries, common use cases include:
---
Choose the appropriate LSR Shore hardness based on your application requirements:
We produce custom-sized overmolded housing parts based on your 2D drawings or 3D CAD models. Our current maximum molding dimension for overmolded parts is 300 mm × 200 mm × 100 mm; for larger parts, please contact our sales team to discuss feasibility. We can accommodate most custom feature requirements, including through holes, threads, undercuts, and surface texturing on the LSR layer.
