Rubber Transfer Molding combines the advantages of injection molding with the ease of compression molding. Rubber transfer molding is the ideal process for forming parts that require:-
- exact positioning,
- bonding rubber to fragile metal parts,
- mold designs that contain multiple cavities and can trap air
The process of transfer molding involves pushing un-vulcanized rubber through sprue into a heated mold. The rubber is placed in a chamber at the top of the mold then placed in a press. During transfer process, rubber is forced through the mold to prevent trapped air while forming the final product.
Transfer molding offers several advantages over other methods by providing:-
- Shorter production cycles
- Maintains closer dimensional tolerances than compression molding
- Provides uniformity,
- Fast mold setup.
