Domestic injection molding for OEMs in automotive, electronics, packaging, and non-sterile medical and lab equipment.Industries UPM Serves

Universal Plastic Mold (UPM) serves OEMs in four industries from its 130,000 sq ft Baldwin Park, California facility: automotive aftermarket and specialty vehicles, industrial and high-end electronics, complex and reusable packaging, and non-sterile medical and laboratory equipment. UPM operates 30 injection molding machines from 150 to 2,000 tons, is ISO 9001:2015 certified and IATF 16949 compliant, and has been in continuous operation since 1962.

Automotive & Specialty Vehicles

Structural Performance & Production Stability

UPM supports automotive aftermarket and specialty vehicle OEMs — RV, upfit, service body, and accessory programs. Typical parts include truck caps, service-body panels, RV exterior components, step pads, interior consoles, mobile video and electronics housings, and structural mounting brackets.

UPM’s three 2,000-ton presses, ~540 oz shot capacity, and 94.5″ × 77.3″ platen enable large structural parts to be molded in one piece, in one facility. ISO 9001:2015 certified and IATF 16949 compliant; PPAP Level 3, First Article Inspections (FAI), APQP, and full lot-level traceability standard.

UPM does not currently serve Tier-1 passenger-car OEMs.

Industrial & High-End Electronics

Cosmetic Precision, PCB Integration & Functional Reliability

UPM molds enclosures, housings, and structural components for industrial controls, NEMA-rated equipment, EV chargers and kiosks, professional AV equipment, networking and IT infrastructure, test and measurement instruments, rugged handhelds, and protective cases.

UPM runs UL-listed flame-retardant grades for regulated applications, and integrates customer-supplied PCBs — functional and continuity testing, then installation into molded components — under one ISO 9001:2015 quality system.

UPM does not manufacture or populate PCB boards.

Complex & Reusable Packaging

Durability, Repeatability & Scale

UPM is a long-standing molder for reusable and industrial packaging OEMs — pallets, totes, crates, bulk containers, and transport-grade dunnage. Primary materials are polypropylene (PP) and high-density polyethylene (HDPE), with glass-filled grades for load-bearing structural applications. UPM supports regrind and recycled-content resin blends where program specifications allow.

Programs typically run 5 to 10 years at hundreds of thousands to millions of pieces annually. Tooling stays in Baldwin Park, California under U.S. legal jurisdiction with full customer ownership and IP protection under U.S. law.

Non-Sterile Medical & Laboratory Equipment

Precision, Documentation Discipline & Selective Scope

UPM molds housings and enclosures for non-sterile medical devices and lab equipment — benchtop diagnostic instruments, in-vitro diagnostic (IVD) instruments, lab automation, durable medical equipment (DME), and non-patient-contact components of Class I and Class II devices.

UPM does not produce sterile devices, sterile fluid-path components, or Class III implantables, and does not operate an ISO 13485 cleanroom. Programs requiring ISO 13485 / cleanroom manufacturing are best directed to specialist sterile-device molders.

UPM supports niche-medical economic minimums as low as 100 pieces per release — below the 500-piece minimum on other programs — reflecting typical diagnostic instrument and benchtop equipment volumes.
