1. How do you prep a Thermoplastic material for compression molding? a. Thermoplastic resins may be loaded into the mold either in the form of pellets or sheet‚ or the mold may be loaded from a plasticating extruder. Thermoplastic materials are heated above their melting points‚ formed and cooled. For both thermosets and thermoplastics‚ the better the feed material is distributed over the mold surface‚ the less flow orientation occurs during 2. What are the advantages‚ Strengths
