Rubber Molding Process for OEM & Custom Rubber Parts
Our advanced rubber molding process utilizes compression molding , injection molding , and transfer molding technologies designed to ensure dimensional accuracy (±0.1mm) , stable material performance , and long service life for critical rubber parts used in sealing, protection, vibration isolation, and noise reduction.
By selecting the correct molding method, curing parameters, and rubber compound formulation, we help customers achieve:
- Consistent rubber part dimensions and superior surface quality with minimal flash
- Reliable sealing and mechanical performance under extreme temperatures and pressures
- High production efficiency for OEM mass production with cycle times from 30 seconds to 5 minutes
- Cost-effective manufacturing with stable quality and repeatable batch consistency
- Complex geometries and tight tolerances for precision automotive components
Complete Rubber Molding Capabilities
Compression Molding – Ideal for large rubber boots, mounts, and bushings with shore hardness 30-90A, using precision molds with controlled temperature (150°C-180°C) and pressure (50-150 bar) for optimal material flow and minimal waste, suitable for NBR, EPDM, silicone, and natural rubber compounds.
Injection Molding – High-precision automated process for O-rings, seals, and small rubber components requiring tight dimensional tolerances (±0.05mm), fast cycle times, and excellent surface finish, particularly effective for high-volume production runs of 10,000+ pieces with consistent wall thickness and minimal post-processing.
Transfer Molding – Optimized for complex shapes with metal inserts, multi-cavity production, and intricate details such as rubber-to-metal bonded parts, valve seals, and custom gaskets where material flow control and insert positioning are critical for part integrity and bonding strength.
