High Volume Custom Plastic Injection Molding
Plastic Injection is the most common method for fabricating high volumes of plastic parts and has a long history. Originally used to manufacture relatively simple products, such as toys, the injection molding process has evolved considerably over the years. PM Plastics has been a part of this history since 1946.
During the injection molding process, molten plastic is forced into a mold, called a tool, shaped like the desired finished product. The plastic cools in the mold, taking the shape of the product, and is ejected. The part is completed after minimal secondary processing.
Injection molding allows for the use of a large diversity of materials — plastic pellets can be premixed, or mixed directly into the hopper of a molding machine, to meet virtually any specification. The process can also produce parts of extremely complexity which would be difficult, costly, or impossible to produce by other means.
At PM Plastics, we operate 3 factories and a 165,000 square foot production facility, 24 hours a day, five to seven days a week. Our molding equipment includes 53 injection molding machines ranging in tonnage from 30 to 1,000. Operating this molding equipment is a highly expert team of designers, engineers, technicians, and quality control specialists.
Since 1946 PM Plastics, has remained a family-owned and operated full-service plastic injection molding U.S. contract manufacturer. Because of our 70 years of experience with plastic tooling and injection molding our engineers can help with a part design for manufacturability as well as meeting the structural and design requirements for its intended use.
