MPP

What MPP does

Massobrio Precision Products (MPP) is a privately held U.S. custom injection mold manufacturer headquartered in Kimball, Michigan, operating out of a single facility at 82 Airport Drive. The firm designs, engineers, prototypes, and produces single-shot, two-shot, prototype, and production injection molds, and complements mold build with in-house short-run molding up to 528 tons, laser welding repair, full mold teardown and restoration, and 3D-printed prototype parts. It is documented as a pioneer in two-shot molding, having developed some of the first two-shot molds in the industry roughly 30 years ago, and serves tier 1 and tier 2 suppliers across automotive, aerospace/aviation, medical/healthcare, military/defense, and consumer products.

Underlying capability rests on a vertically integrated equipment base that includes multiple Mazak, Makino, YCM, and Fadal CNC machining centers (including a YCM 5-axis), Mitsubishi wire and die EDM with System 3R robotics, an ALM 300 laser welder, an Ultimaker S5 fused-filament-fabrication printer, Haitian injection presses from 101 to 528 tons, and Mitutoyo/Aberlink inspection equipment. The firm is led by Carlo Massobrio as President, supported by six journeymen mold makers with combined experience exceeding 100 years.

MPP's business model is project-based and quote-driven: customers submit part data and specifications, receive an RFQ response, and MPP produces a custom mold or short-run part. Revenue is generated from one-time mold fabrication projects, recurring mold maintenance and repair, and professional services including in-house molding and laser welding. The go-to-market is enterprise field sales with a dedicated customer support representative and project engineer per account, complemented by an owned no-distance-limit delivery fleet for molds up to 18,000 lbs. Named enterprise customers include Cooper Standard, TRW Automotive, AutoLiv, Behr, TI Automotive, Hi-Lex, Raymond Tinnerman, Prism, Atlantic Precision Products, St. Clair Technologies, GVS, Zila, and Orchid. Strategic positioning rests on a regulatory stack — ISO 9001:2015, ISO 14001:2015, IATF 16949:2016 (through 2027), ITAR, with AS9100D in progress — that gates access to automotive, defense, and aerospace customers and on a stated move from pure mold build into molding and automation services.
