Urethane material can be cast using a compression process. The polymers and curative is premixed and poured into a mold. The mold is overfilled with raw material so that when the mold plates are fit together and placed under pressure, the excess material helps to carry out the air. After parts reach a “green strength”, they are demolded and moved to a secondary post cure oven.
Typical Materials used for Cast Molding:
- Filled Polyurethanes
- Epoxy Resins
