Liquid & Solid Silicone, Rubber & Elastomer Integrated Injection Molding
Food Grade, Medical Grade, Industrial Grade Silicone & Rubber Products with High Temperature Resistance & Waterproof Performance
Overview: We specialize in custom silicone and rubber molding services, covering Liquid Silicone Injection Molding (LIM), solid silicone molding, and rubber compression/injection molding. We offer end-to-end solutions from mold design and material selection to pilot runs and mass production. Our technology excels in high-demand applications requiring flexibility, waterproofing, heat resistance, chemical resistance, and biocompatibility. With in-house mold facilities, we meet precise requirements for part accuracy, hardness, and appearance. Finished parts are smooth, burr-free, and fully compliant with global export standards.
Silicone molding is a manufacturing process using synthetic silicone rubber, known for its wide temperature range (-40°C to 200°C+), non-toxic properties, and excellent UV/aging resistance. It’s ideal for food-grade, medical, and high-temperature applications.
Rubber molding forms parts from natural or conventional synthetic rubbers (like NBR, EPDM). It’s a cost-effective solution for standard industrial seals and parts, though it has lower heat resistance and is more prone to aging than silicone.
Liquid Silicone Injection Molding (LIM)
High-speed, high-volume production for precision silicone parts with complex geometries, ideal for medical and food-grade applications.
Solid Silicone & Rubber Compression Molding
Cost-effective solution for large or thick silicone/rubber parts, suited for low to medium production runs.
Custom Silicone & Rubber Extrusion
Continuous silicone or rubber profiles such as tubes, strips, and seals for consistent cross-section requirements.
Insert & Overmolding
Silicone or rubber bonded to metal or plastic inserts to form integrated assemblies with enhanced functionality.
Custom Tooling & Prototyping
Fast mold design and rapid prototyping to validate designs before full-scale silicone/rubber production.
Secondary & Finishing Services
Including trimming, surface coating, printing, and adhesive backing to meet final assembly needs for both silicone and rubber parts.
Liquid Silicone (LSR) Injection Molding
Short for LSR molding, it has strong fluidity and fast molding speed with high product precision and no peculiar smell. It is suitable for medical supplies, baby products, and precision waterproof parts, and can realize ultra-thin wall complex structure molding.
Solid Silicone & Rubber Compression Molding
For HCR silicone and conventional rubber compounds, it offers high cost performance, a wide hardness selection range, strong toughness, and wear resistance. It is mostly used for industrial seals, home appliance accessories, and outdoor wear-resistant parts.
Rubber & Silicone Injection Molding
Automatic injection production with high mass production efficiency. Finished products have smooth, burr-free appearances and stable, unified dimensions, suitable for standardized mass production of both rubber and silicone accessories.
Custom Silicone & Rubber Molding
We support custom special-shaped structures, special colors, and special hardness silicone and rubber products according to drawings and samples. We adjust production technology on demand to meet the needs of non-standard products.

Product Air Bubbles
Multiple grades meet international testing standards, including RoHS and REACH compliance. Medical and food-grade options are available for devices, baby products, and food-contact applications, ensuring reliability across consumer, industrial, and medical use cases.
Delivers excellent sealing, shock absorption, and anti-slip properties, providing reliable protection and grip in harsh environments. Ideal for industrial seals, dampers, and non-slip components.
Silicone maintains stable performance at extreme high and low temperatures, while rubber performs reliably in common industrial ranges. Both materials feature strong anti-aging properties, preventing deformation and cracking even after prolonged use.
Streamlined injection/compression molding eliminates secondary assembly steps, reducing costs and improving manufacturing efficiency for complex, one-piece designs.
Custom colors, hardness grades, surface textures, and dimensions are available to match your brand aesthetic and functional requirements, with no extra fees for basic adjustments (excluding specialized tooling).
Liquid silicone (LSR) offers high precision and fast cycle times for complex, medical/food-grade parts. Solid silicone (HCR) is more cost-effective for large/industrial components. Rubber provides excellent wear resistance and cost performance for general industrial use. The best choice depends on your application requirements.
Liquid silicone has higher cleanliness, suitable for high-end medical and baby products; solid silicone has higher cost performance, suitable for general industrial daily necessities, choose according to demand.
Yes. Both materials can be engineered to provide excellent sealing, waterproofing, and electrical insulation, making them ideal for electronic, automotive, and outdoor applications.
Absolutely. We offer custom colors, finishes, and hardness grades for both silicone and rubber to match your brand specifications and functional needs.
High-quality silicone and specialty rubbers (like EPDM, FKM) are formulated for excellent UV, ozone, and heat resistance. They resist aging, cracking, and discoloration far better than many other materials when properly specified.
