Plastic Products Company, an employee-owned injection molder founded in 1962, provides design-to-delivery manufacturing services for customers worldwide. The company, founded in Minnesota, has expanded into thermoplastic, metal and ceramic molding and operates nine production sites running automated lines around the clock.

PPC traces its origins to the 1950s, when founder Willard “Smitty” Smith worked as a mold-making specialist at Minnesota Mining and Manufacturing, or 3M. In 1957, he established Smith Metal Products in Lindstrom, Minn., concentrating on tooling and metalworking.

In 1962, the company added injection molding machines and began contract assembly of molded components to serve 3M, a step that marked the formal founding of Plastic Products Company. PPC says it remains employee-owned and has since built a manufacturing network spanning nine facilities.

PPC’s production capabilities cover injection molding in thermoplastics, metal powders and ceramic powders. The company operates nine manufacturing facilities worldwide, using highly automated 24/7 lines to balance industrial-scale output with close customer service.

Its service model includes project management across the full cycle, from design and development through final production. The company presents the model as a way to manage programs across different materials and production volumes.

PPC follows international quality management standards and says its products are designed to meet regulatory requirements across industries. Its principal certifications include ISO 9001:2015, Underwriters Laboratories certification at all production sites and NSF certification for products, materials and components used in specific sectors.

The company also states that it complies with Section 1502 of the Dodd-Frank Act, which requires supply-chain disclosures related to conflict minerals. PPC says its supply chain does not include tantalum, tin, tungsten or gold from the Democratic Republic of Congo or surrounding areas.
