How does compression moulding work
Did you know?
WebCompression moulding is a rubber moulding process in which the moulding material is placed in an oven (when already been preheated) and heated mould cavity. To ensure that the right pressure can be applied the mould is closed with a top force or plug member. This member forces the material to flow into all the mould areas. WebNov 4, 2024 · For compression molding simulations, a compression zone of 1 mm was defined to model the initial mold opening and loading of the pellets. The initial polymer charge is outside the cavity; hence, the compression zone is necessary to solve the Eulerian equation for the polymer flow. The compression zone was meshed using 3D prism …
