Capabilities of Molded Rubber Parts
To be honest, there is no best processing technology, only suitable technology. Our professional engineering team is happy to discuss your project and share our project experience to save money and effort.
Compression Molding Services
Silicone Compression Molding process is to place the preformed silicone solid silicone (HCR) into a heated mold, and through heating and pressurization, the silicone flows and fills the mold cavity, and solidifies (vulcanizes) into shape. Suitable for products that do not require high precision but need to be durable (such as sealing rings, kitchen utensils).
Rubber Injection Molding Services
Rubber injection molding is a high-efficiency process designed for the mass production of complex, precision rubber components. It involves preheating the rubber compound and injecting it under high pressure into a closed, temperature-controlled mold. This method ensures short cycle times, tight dimensional tplerances and excellent part-to-part consistency.
Overmolding Services
Rubber overmolding is a process that utilizes rubber injection molding technology to bond rubber materials with various substrates (including engineering plastics, metal alloys, ceramics, etc.), creating integrated components with composite functionalities. This enables specialized applications such as shock absorption and waterproof sealing.
Extruded Rubber Services
The rubber extrusion process is a processing method that forces rubber raw materials (solid compound or liquid rubber compound) through a custom mold and design die (die/DIE) under heating and pressurization conditions to produce long strip products with a specific cross-sectional shape. It is widely used in the production of products such as sealing strips, hoses, and light strips.
Raw Materials Of Custom rubber parts
Material selection is critical for project success. Each rubber compound delivers distinct characteristics and we engineer custom rubber parts with application-specific formulations tailored to environmental and performance demands. The optimal material ensures component stability, functionality and long-term durability
