Polymer molding process
WebThe repetitive nature of the compression molding process makes the molds to be damaged. This molding process is not suitable for making complex parts. The labor cost is higher in this molding process. The wastage of thermoset plastics is more compared to thermoplastics. Applications of Compression Molding Process: Webpolymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or …
