Professional Compression & Injection Rubber Molding Service
Oil-resistant, wear-resistant, high-temperature resistant elastic rubber parts full customization
Overview：We provide one-stop custom rubber molding solutions for seals, gaskets, and O-rings, with full mold design and maintenance support. Our high-performance rubber parts meet the oil resistance, durability, and precision requirements of harsh industrial and automotive applications.
Rubber molding is an industrial rubber manufacturing technology that vulcanizes natural rubber and synthetic rubber into finished products via professional molds under high temperature. It is widely used to produce seals, shock pads, anti-slip parts and wear-resistant industrial rubber components with high elasticity, toughness, corrosion resistance, insulation and flame retardancy. We support non-standard special-shaped custom rubber products for various industries.
Compression Molding
Ideal for large, thick and hard rubber parts. Suitable for low-to-medium volume production.
Injection Molding
High efficiency for complex, precise parts. Perfect for mass production with stable quality.
Transfer Molding
Balances precision and durability, widely used for industrial sealing and insulated components.
Custom Rubber Molding
Tailored products per your drawings, samples and special performance requirements.
Main Rubber Molding Processes
Put mixed rubber material into mold cavity, then vulcanize and shape under high temperature and pressure. It features low mold cost, ideal for simple structure and thick-wall rubber products, flexible for small and medium batch orders.
Rubber Injection Molding
Automatic high-temperature injection vulcanization molding with uniform feeding and stable curing. Finished products own high dimensional accuracy without burrs, high production efficiency, perfect for precision small parts and large-volume standardized rubber components.
Custom Rubber Molding
Custom exclusive structure, hardness, color and functional rubber products according to customer drawings and samples. Support insert embedding and hard-soft composite molding to meet special working condition demands.

🚫 Air bubbles and material shortage
✅ Optimize mold venting, adjust vulcanization temperature and feeding volume
🚫 Uneven shrinkage and deformation
✅ Balance mold temperature and extend constant temperature vulcanization time
🚫 Surface whitening
✅ Use pure rubber material and clean mold cavity oil dirt
🚫 Unqualified hardness
✅ Precisely adjust rubber formula and vulcanization parameters
We operate both compression and injection molding lines under one roof, covering small-batch prototyping to high-volume mass production. This end-to-end control ensures stable lead times and consistent quality at every stage.
We stock and formulate a full range of rubber materials (NR, NBR, EPDM, Silicone, FKM, etc.) to meet your exact needs, from oil resistance and high-temperature tolerance to FDA/ROHS-compliant food contact safety.
Our mature vulcanization and molding processes are paired with rigorous in-line testing, ensuring every part maintains stable elasticity, consistent hardness, and reliable anti-aging performance over its entire lifecycle.
We design for manufacturability, using integrated molding to reduce assembly steps, eliminate secondary operations, and cut overall production costs without compromising quality.
We provide rapid mold design and prototyping based on your drawings or samples, with fast turnaround times to accelerate your product launch and reduce time-to-market.
From raw material inspection to final product testing, we implement full-process quality control. Our one-stop service includes material sourcing, molding, secondary processing, and delivery, simplifying your procurement while guaranteeing traceable, high-quality results.
Compression molding is more cost-effective for simple thick-wall parts; rubber injection molding is better for precision small parts and high-volume products.
We produce food-contact and medical eco-friendly rubber products with relevant test reports available.
Yes, we supply various solid rubber and liquid silicone rubber raw materials separately with favorable bulk price.
Custom integrated logos, grains and scales are available, as well as post silk printing and laser engraving
We accept sample development, trial orders, mass OEM orders and rubber raw material procurement
