Headquartered in Butler, WI, MRPC is a family-owned, single-source provider of medical device components and assemblies. The company began in 1921 during major industrial growth in Milwaukee. MRPC supplied rubber and thermoplastic components for some of the world’s leading producers of small engines, power tools, plumbing supplies, electrical systems, and brewing and bottling equipment.

As business grew, so did MRPC’s reputation for quality, service and delivery. In addition to industrial products, the company also produced rubber and plastic medical device components early on. Realizing the medical market was a significant opportunity for the future, company leaders gradually shifted focus toward medical components.

By the 1980s, MRPC began converting some of its molding facilities into clean room manufacturing environments to support the medical device community. In 2012, MRPC acquired ETI, a silicone molder in Largo, FL, now known as MRPC Southeast Division. The addition expanded MRPC’s capacity and widened its presence in the southeastern and eastern U.S.

In 2016, MRPC acquired Johnson Precision (JPI) based in Hudson, NH, a global supplier of plastic injection-molded components and assemblies. Now known as MRPC Northeast Division, this acquisition added mold-making capabilities, more clean room capacity, and expertise in thermoplastic molding and assemblies for medical devices.

In 2021, MRPC celebrated its 100th year in business. Now a full service medical device contract manufacturer, MRPC offers services that extend the full life-cycle of your medical device, instrument and disposables projects.
