What Milwaukee Precision Casting does

Milwaukee Precision Casting, Inc. (MPC) is a family-owned investment casting manufacturer founded in 1993 and headquartered in Milwaukee, Wisconsin. The company operates a single facility and uses the lost-wax (investment) casting process to produce precision components for defense, medical, oil & gas, petrochemical, food & dairy, agriculture, power transmission, construction, mining, machine tool, and other industrial end markets. Its regulatory credentials — ISO 9001:2015 certification, AMS 2175 compliance, and ITAR registration — qualify it for military weapons systems and defense work, which is a primary commercial focus.

MPC's core capability is the lost-wax casting process, executed with proprietary in-house robotic shell room automation built around Fanuc and KEA Automation equipment. The company casts a wide spectrum of alloys — carbon steel, alloy steel, stainless steel, tool steel, nickel-based alloys, bronze, and aluminum — with cast weights ranging from a few ounces up to 30 lbs. Compared to conventional tool steel tooling, MPC's use of aluminum tooling reduces per-piece tooling cost and lead time, supporting competitive pricing in low-to-mid volume runs.

Revenue mechanics are project-based B2B manufacturing. MPC earns revenue through tooling charges and per-piece pricing on custom cast parts, with go-to-market driven by direct sales, engineering engagement, and trade show participation — most notably SHOT Show for firearms and defense OEMs. The customer base is industrial and diversified across 15+ named verticals, with documented work for military weapons systems and the New York City Transit Authority. Pricing is part-specific rather than subscription-or-volume-based, and the business model is fundamentally a custom specialty foundry competing on regulatory qualifications, in-house automation, and engineering responsiveness rather than scale.

Core offering

Milwaukee Precision Casting is a custom investment (lost wax) casting foundry that produces precision metal cast components in a wide range of alloys for industrial customers. The company manufactures cast parts to customer specifications and complements this with secondary manufacturing services (machining, finishing, and assembly) to deliver ready-to-install components. It serves industries including firearms/military, medical, oil and gas, agriculture, food and dairy, construction, mining, and the automotive aftermarket.

Product overview

Milwaukee Precision Casting is an ISO 9001:2015 certified investment casting manufacturer providing end-to-end precision metal component solutions since 1993. Their core offering is investment casting using the lost-wax process, supplemented by CNC machining, heat treatment, surface finishing, and comprehensive NDT inspection services (X-ray, MPI, FPI, HIPing). They work with a broad portfolio of alloys including stainless steel (304, 316, 410, 416, 420, 15-5, 17-4 PH), aluminum (A356), carbon steel (4130, 8620, 4140), cobalt alloys (6, 12, 21), brass, bronze, and tool steel. Their products range from miniature parts (1/10 ounce or less) to large castings up to 50 pounds. They serve demanding industrial markets including commercial firearms and military (ITAR registered, AMS 2175 compliant), medical, oil and gas, petrochemical, food and dairy, agriculture, construction, mining, power transmission, utilities, waste management, logging, machine tool, and automotive aftermarket. They recently introduced Fanuc and KEA Automation technology for improved shell processing and surface finish quality.
