Manufacturing Process of Rubber Molded Parts
Rubber molding typically involves the following steps:
- Material Selection: Rubber compounds are selected based on physical, chemical, and mechanical properties required by the application.
- Mold Design: CAD software is used to design precision molds tailored to the component geometry and tolerance.
- Molding Process: Depending on the complexity, one of three main molding methods is used:
• Compression Molding: Best for medium to large parts with simple shapes.
• Injection Molding: Ideal for high-volume, high-precision parts.
• Transfer Molding: Suitable for producing parts with inserts or complex shapes.
- Curing (Vulcanization): The rubber compound is heated and cured under pressure to set its final shape and properties.
- Trimming and Inspection: Flash removal, surface finishing, dimensional checks, and functional testing are conducted to ensure product integrity.
