Plastics fabrication processes

Certain plastics provide higher strength and stiffness a broad range of properties exit. Even though there are literally over 35,000 plastics available worldwide (for all plastic fabricating processes) only a few hundred are used in RPs. In turn only a few of those are predominantly used in most of the RPs. The thermoplastics (TPs) include principally nylons and polypropylenes, as well as polycarbonates, acetals and polyesters. Thermosets (TSs) include predominantly polyesters as well as epoxies, phenolics and urethanes. 

Basically the variable cost elements are those elements of piece cost whose values are dependent on the number of pieces produced. For most plastics fabrication processes the principal variable cost elements are the material, direct labor, and energy costs. 

Inlay or overlay They can be applied to plastic fabricating processes such as moldings during or after molding.

Multilayer coextrusion of thermoplastic film and sheet has developed into an important plastic fabrication process, providing large growth opportunities for the plastics industry. Coextruded multilayer plastics are challenging such traditional materials as metals, glass, paper, and textiles.
