Lower operating temperatures are more desirable as they reduce the viscosity making it easier to fill the cavity
This process can be used for both thermosets and thermoplastics as they can both be thermally shaped
This process can only be used for thermosets as they can thermally cure from the monomer state
This process is suitable for rubber, PVC and polymethyl methacrylate
Transcribed Image Text:Compression molding is a manufacturing process in which the molding material is preheated then
