Our comprehensive LSR overmolding capabilities empower B2B product designers worldwide to develop durable, high-performance, and aesthetically superior products that stand out in competitive markets.
1. Exceptional Durability and Temperature Resistance
Liquid Silicone Rubber overmolding provides products with remarkable durability that withstands extreme environmental conditions. LSR can operate efficiently across a temperature range from -55°C to +300°C, making it ideal for applications exposed to high heat, cold, or rapid temperature fluctuations.
Why it matters:
This extraordinary temperature resistance ensures that products retain their structural integrity and performance stability, even in harsh environments such as automotive engines, industrial machinery, or medical sterilization equipment. The inherent chemical inertness of silicone also grants resistance to UV radiation, ozone, and oxidation, prolonging the lifespan of the final product.
2. Superior Flexibility and Elasticity for Enhanced User Experience
One of the hallmark benefits of liquid silicone rubber is its outstanding flexibility and elasticity, which are critical in applications requiring soft-touch surfaces, shock absorption, or flexible joints.
Key advantages include:
High elongation at break (up to 700%)
Excellent compression set resistance
Consistent tactile feel that enhances user comfort and grip
Impact on product design:
This flexibility not only improves user ergonomics but also reduces the risk of cracking or tearing during assembly or use, especially in wearable devices, medical tubing, or consumer electronics.
3. Precise and Complex Overmolding Capabilities
Liquid silicone rubber overmolding allows for highly precise and intricate designs, enabling manufacturers to produce complex geometries that were previously difficult or impossible with traditional molding methods.
Features include:
Fine detail replication
Multi-material integration for composite components
Thin-walled overmolds for lightweight yet durable parts
Benefits for B2B product design:
This precision facilitates integrated sealing, customized textures, and aesthetic enhancements, resulting in products that stand out in a crowded marketplace.
4. Superior Chemical Resistance and Biocompatibility
Liquid silicone rubber is highly resistant to chemicals, including oils, solvents, and cleaning agents. Its biocompatibility makes it suitable for medical devices, food contact applications, and personal care products.
Key points:
Meets stringent medical standards (ISO 10993, USP Class VI)
Non-toxic and hypoallergenic, suitable for skin contact
Resistant to mold, bacteria.
Implication for B2B clients:
Manufacturers can confidently develop products that require frequent sterilization or contact with sensitive skin, such as medical implants, wearable health monitors, and food processing equipment.
5. Enhanced Aesthetic Appeal with Color and Texture Options
Liquid silicone overmolding offers vast customization options for color, texture, and surface finish, enabling brand differentiation and improved user appeal.
Customization features:
Vivid color matching for branding or functional cues
Textured surfaces for better grip or aesthetic effects
Soft-touch finishes that enhance tactile experience
Market advantage:
This level of customization allows B2B companies to tailor products precisely to customer preferences, increasing marketability and customer satisfaction.
6. Improved Sealing and Insulation Properties
LSR overmolding provides superior sealing capabilities, making it ideal for waterproof, dustproof, and EMI/RFI shielding applications.
Advantages include:
Enhanced environmental sealing to prevent ingress of moisture, dust, or contaminants
Electrical insulation for sensitive electronic components
Vibration dampening for delicate parts
Application significance:
In industries such as aerospace, medical, and electronics, these properties are critical for product reliability and compliance with safety standards.
7. Cost-Effective and Efficient Manufacturing Process
While liquid silicone rubber overmolding may seem complex initially, it offers cost-effective benefits in the long run, including reduced assembly steps, fewer components, and lower material waste.
Manufacturing efficiencies:
Reduced assembly time due to integrated overmolds
Less need for secondary finishing
High repeatability ensures consistent quality across large production runs
Environmental impact:
The process minimizes material waste and supports sustainable manufacturing practices, aligning with global eco-conscious trends.
