Universal Plastic Mold (UPM) is a family-owned custom plastic injection molder founded in 1962 in Baldwin Park, California, operating 30 injection molding machines from 150 to 2,000 tons. UPM is ISO 9001:2015 certified and IATF 16949 compliant. UPM supports OEMs across four primary markets — automotive, electronics, medical and laboratory equipment, and packaging — and takes on selective consumer goods and hardware work, with role-specific solutions for supply chain, engineering, and program management teams.


Procurement leaders are accountable for Total Cost of Ownership, supplier stability, and capital efficiency.
UPM supports this through:
U.S. dollars, U.S. freight, U.S. labor — no tariff exposure, no ocean freight volatility, no currency risk.
Engineering teams are responsible for functionality, performance, and cosmetic integrity.
UPM supports this through:
Most molding defects — sink marks, knit lines, warpage — are determined before tooling is cut. Early collaboration prevents the late-stage corrections that delay launches.


Program managers are responsible for adherence to timelines, issue resolution, and cross-functional communication.
UPM supports this through:
Programs that previously required four or five separate suppliers can be managed through a single Account Manager.

Regardless of role, manufacturing success depends on integration.
UPM combines:
