Custom Rubber Covers Made With Versatile Processing Capabilities
1. Liquid Injection Molding
The Liquid Silicone Rubber (LSR) molding process meets the manufacturing demands of silicone rubber sleeves with complex structures and high performance requirements. It offers high precision, excellent consistency, and design flexibility, endowing the product with outstanding sealing performance, durability, and batch-to-batch stability.
Precision molding
LSR molding can achieve micron-level structure replication (such as 0.1mm thin wall) and can perfectly reproduce the fine texture of the product surface;
Zero pollution in production environment
Automated cleanroom production prevents external contamination and complies with medical-grade sterility standards.
Mass production
Rapid prototyping cycles with high product consistency.
2. Silicone Compression Molding
Compression molding of silicone rubber is well-suited for producing custom large-size or thick-wall silicone parts. It features low mold costs and supports small-batch customization with various rubber materials, hardness levels, and multi-color blends—ideal for manufacturing custom rubber covers, custom silicone grips, customized connector rubber boots, custom EPDM rubber covers, and custom rubber bellows.
Fast Mold Making with Competitive Pricing
The mold processing cycle is short and the cost is low, which is suitable for small batch production.
Wide Material Selection & Customization
Wide range of material selection, solid silicone (HCR) with different hardness (Shore A 10~80), customized color and performance (high temperature resistance, UV resistance) can be used.
Customized Large-Scale Production
Suitable for large-sized silicone products.
3. Overmolding Capabilities
Our Overmolding process can seamlessly cover silicone or rubber on the surface of engineering plastics, metal alloys and other materials to form an integrated silicone skin with functional integration, structural stability, waterproofness, dustproofness, anti-slipness and comfortable grip. It is widely used in customized rubber bellows, silicone grips and connector rubber boots and other products.
Cost and process advantages
The multi-material integrated molding process can firmly combine rubber with plastic, metal and other materials to create a silicone protective cover with structural integration and functional integration (such as waterproof, dustproof and anti-slip), while reducing the bonding and assembly processes, improving production efficiency and reducing manufacturing costs.
Flexible design
It can achieve seamless covering of complex 3D curved surfaces, meet product design requirements in appearance, protection and ergonomics, support two-color, multi-color encapsulation and complex shapes, and enhance design flexibility and brand recognition.
The Function of Custom Silicone Cover
Using silicone to customize protective covers offers several practical benefits:
We use FDA and LFGB-compliant medical and food-grade silicone materials to customize custom silicone sleeve, medical slicone syringe, and silicone skins for device, including silicone bellows for injectors. These protective covers are non-toxic and low-allergenic, making them safe for contact with food and skin. They are ideal for use in food-related applications, children’s products, and medical devices.
Silicone can operate stably in a wide temperature range from -40 °C to 200 °C (-40 °F to 392 °F), making it suitable for high-temperature and extreme environments—ideal for customized silicone cooking mat, silicone glove, food thermometer,etc.
Silicone material is easy to process complex designs and supports customization in a variety of colors. It has excellent elasticity and cushioning properties, can fit the product tightly, and achieve multiple protections such as dustproof, waterproof, and shockproof, effectively protecting valuable equipment. Common applications include silicone bottle boots, bicycle handle cover, etc.
The EPDM protective cover offers excellent resistance to weathering, ozone, and UV exposure, along with outstanding sealing performance. It is well-suited for high-temperature, humid, and outdoor environments, and retains its properties even after prolonged exposure to the elements. Common applications include rubber bellows, boots for connector, etc.

1. Silicone Protective Cases for Electronic Products
2. Silicone Protective Sleeves for Personal Products
3. Silicone Protective Covers for Medical Products
4. Silicone Protective Skins for Industrial & Automotive Products
Special Properties of Custom Silicone Skins
Silicone protective covers can also be manufactured using the overmolding process, which seamlessly integrates silicone rubber with other materials into a single part or product. This approach combines the structural properties of the base component with the protective benefits of silicone. An overmolding silicone cover helps prevent damage from scratches, dust, and general wear and tear. It can also be customized with different colors, designs, and surface textures to give the device a distinctive appearance.
