Transfer molding can be considered a lower cost version of injection molding. It is one of three process options for custom rubber moldings that Archer offers.
Typically, the mold design requires multiple plates that must be assembled and dissembled between each molding cycle.
Once the mold has been assembled, a charge of compound is placed into a chamber or pot.
As the press closes, a plunger, which is part of the tool design, forces the material through a system of runners and sprues and into the mold cavity itself.
Once the material has been cured, the press is opened and the plunger withdrawn. The mold is then disassembled and the product is removed.
Advantages of Transfer Molding:
- More adaptable to rubber/metal bonding than compression molding
- Creates lower level of flash than other processes
- Better tolerance capabilities than compression molding
- Lower tooling costs than injection molding
Disadvantages of Transfer Molding:
- Greater amount of waste material than other molding processes
- Cost per cavity is likely to be greater than with compression molding
Archer has the capability and expertise to utilize the best molding process for any particular application.
