Like compression molding, transfer molding also utilizes a press and mold. The main difference is that in transfer molding, a piston forces the material through a passage into the mold cavity. While transfer molding can be more costly and take more time than compression molding, this method produces more complex products with a tighter tolerance control while still maintaining a higher production rate.

Benefits of Compression Molding:

Produces more intricate products

Fewer knit lines

Low tooling costs

Rapid production

Handles high durometer materials

Best Used For:

Low to medium volumes

Bulky products

Large range of materials

Larger products

Gaskets, seals and o-rings
