About Lmc Industries Inc
LMC Industries was founded in 1945 in Arnold, Missouri, by toolmaker Fred Suellentrop, Sr., who set out to build high-quality equipment that would improve the manufacturability of essential products. The company remains family-owned today, operating from a 240,000-square-foot facility in the St. Louis metro area. The company operates as a contract manufacturer specializing in precision metal stamping — including progressive die stamping, in-die tapping, and in-die assembly — and plastic injection molding, insert molding, and overmolding. It also maintains a 14,000-square-foot tool room equipped with CNC milling, wire and conventional EDM, water jet machining, and TIG welding for in-house die and mold fabrication, repair, and maintenance. Additional in-house capabilities include welding, riveting, chemical passivation, and assembly, supported by partner networks for heat treating and metal finishing. LMC serves OEMs and tiered suppliers across automotive, agricultural, consumer products, medical device, and hand-tool markets. Its components appear in every major automotive program worldwide, in harvesting equipment and livestock feeding systems, in medical device grips, and in everyday items such as screwdriver handles, toothbrush handles, and the press-down valve on whipped topping cans. The company differentiates itself by housing both metal and plastic production under one roof, enabling single-source accountability, compressed lead times, and integrated design-for-manufacturability (DFM) reviews across materials. Its quality system follows APQP and PPAP protocols with first-article inspections, and its transfer-tooling process allows it to take over existing programs with minimal disruption.
