Polypropylene (PP) is a thermoplastic polymer that can be injection molded into various products. Injection molding machinery
is used to produce parts made of PP by injecting heated polymer into a mold, where it cools and solidifies into the desired shape. These machines typically have a barrel that melts the polymer, a screw that pushes the melted polymer into the mold, and a mold that is clamped shut while the polymer cools and solidifies.
