Our Molded Rubber Parts Capabilities
There is no single best processing method for Custom Rubber Molded Products, only the most suitable one for each application. Our engineering team is ready to review your project and recommend the most cost-effective solution.
Compression Molding Services
Compression molding places preformed solid rubber (HCR) into a heated mold, where heat and pressure cause the material to flow, fill the cavity, and vulcanize into shape. It is ideal for compression molded rubber parts and molding silicone rubber parts that prioritize durability over tight tolerances, such as sealing rings and gaskets.
Rubber Injection Molding Services
Rubber injection molding is a high-efficiency process for mass-producing complex, precision rubber components. The compound is preheated and injected under high pressure into a closed, temperature-controlled mold. As an experienced automotive rubber parts manufacturer, we use this process to produce automotive molded rubber parts with short cycle times, tight tolerances, and consistent part quality.
Overmolding Services
Rubber overmolding bonds rubber to substrates including engineering plastics, metal alloys, and ceramics, creating integrated components with composite functionality. It is widely used for custom automotive rubber parts requiring shock absorption, waterproof sealing, or vibration isolation.
Rubber Extrusion 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 for Custom Rubber Parts
Material selection is critical to project success. As a leading silicone rubber products manufacturer and established among epdm rubber products manufacturers in China, we engineer each compound to match specific performance demands, including custom epdm rubber parts for weather-resistant applications. The optimal material ensures component stability, functionality, and long-term durability.
FAQs About Custom Rubber Parts
Can you manufacture custom rubber parts based on my existing sample?
Yes. We can develop custom rubber parts based on your existing sample. Our team can review the part’s size, shape, material, hardness, and application requirements, then support drawing development, tooling, and production.
Do you support custom rubber parts for automotive, medical, and industrial applications?
Yes. We manufacture custom rubber parts for automotive, medical, industrial, electronics, machinery, and other B2B applications. Material selection, molding process, and quality requirements can be matched to your product’s use environment and performance needs.
Can you help optimize a rubber part design before mold production?
Yes. Before mold production, our engineering team can review your design for manufacturability, material performance, sealing function, durability, and cost efficiency. This helps reduce tooling risks and improve production consistency.
What dimensional tolerances can you hold for custom molded rubber parts?
Tolerance depends on the part design, material, molding process, and production volume. We review tolerance requirements during the drawing and tooling stage to make sure the finished parts meet your functional needs.
What quality inspection process do custom rubber parts go through before shipment?
Custom rubber parts can be checked for dimensions, appearance, hardness, material, and functional requirements before shipment. Inspection documentation can also be provided when required by your project specifications.
