Technical Capability at ScaleWithout Operational Risk

UPM is built for hard-tooled production programs that require both press tonnage and integrated downstream scope.

Equipment

30 injection molding machines from 150 to 2,000 tons, including 5 presses at 1,500 tons or higher and 3 at 2,000 tons — among the largest tonnage capacity on the U.S. West Coast.

Engineering and DFM

UPM does not build new molds in-house; new-mold builds are managed from design through sampling with established mold-builder partners. UPM’s own Baldwin Park tool room handles mold maintenance, repair, and engineering changes on the tools UPM runs — under the same ISO 9001:2015 quality system as production. UPM engineering supports Design for Manufacturability review on new programs, with material selection, gate placement, draft, and cycle-time analysis completed before tooling cuts.

Quality system.

ISO 9001:2015 certified (Certificate #1715, issued by Amtivo); IATF 16949 compliant. PPAP Level 3, First Article Inspections (FAI), and full lot-level traceability are standard documentation. 5.4 Sigma DPMO on a 12-month rolling basis.

Volume range.

500 pieces per release through annual volumes in the millions, with 2–3 week production lead times post-tooling.

UPM, Inc.One Facility, One Quality System, One Point of Contact

Every step of program execution runs through one ISO 9001:2015 quality system in one Baldwin Park facility:

Kitting, packaging, and drop-ship
Injection molding (150–2,000 tons)
Painting, silk-screening, hot-stamping
Mechanical assembly and PCB integration

Single point of program ownership. The Account Manager who quotes the program is the same person who manages it through tooling, PPAP, production launch, and ongoing supply. There is no handoff between sales and program management.

Direct executive access. New customers receive a welcome letter from UPM’s President with direct email and mobile phone contact.

Executive Business Reviews. UPM holds Executive Business Reviews annually with all active customers — attended by UPM’s President, presenting on-time delivery, RMA, and corrective action data.

In-house tool room. Mold maintenance, repair, and engineering changes are performed in UPM’s own Baldwin Park tool room rather than outsourced — keeping tooling on-site and under the same quality system for operational control and production continuity. See In-House Tooling Services →

U.S.-Based Production and Customer-Owned Tooling

All production runs in Baldwin Park, California. Customer-owned tooling stays on-site under U.S. legal jurisdiction and transfers to the customer upon payment in full. The customer retains tooling control regardless of supplier relationship outcomes.
