What MRPC does

MRPC (Molded Rubber and Plastic Corporation) is a U.S. medical device contract manufacturer founded in 1921 and headquartered in Butler, Wisconsin, with two additional U.S. production sites in Hudson, New Hampshire (acquired 2016 as Johnson Precision) and Largo, Florida (acquired 2012 as ETI). The company operates as a single-source turn-key manufacturing partner to medical device OEMs, providing integrated services across the full product lifecycle: Design for Manufacturability (DFM) engineering, silicone (LSR/HCR) and thermoplastic injection molding, multi-material/two-material molding, finished medical device assembly (including ultrasonic welding and sterile packaging), sterilization management, and global supply chain services (VMI, MRP, ERP, EDI, Kanban, JIT). Core technical capabilities include ISO 7 and ISO 8 cleanroom manufacturing, scientific molding with RJG instrumented tooling, flashless silicone molding via custom automation work centers, and a proprietary multi-material molding process for chemically/mechanically bonding dissimilar materials.

The company has been family-owned across three generations for over 100 years, achieved ISO 13485 certification in 2009 (among the first in Wisconsin), and earned MedAccred Injection Molding accreditation in 2022 (renewed with Merit status). It sells primarily to enterprise medical device OEMs via a direct field-sales model staffed by regional Business Development Managers covering the East Coast, West Coast, and Midwest. Programs span Class I-III medical devices including surgical implantables, sleep apnea devices, ventilator components, and COVID-19 testing equipment, with multiple programs lasting over 50 years.

MRPC's revenue model is project- and program-based contract manufacturing with quote-driven, multi-year engagements; pricing is set per-project based on design complexity, materials, tooling, volumes, and assembly/packaging scope. In October 2025, the company entered a strategic partnership with private equity firm Vance Street Capital to fund larger capital investments, pursue acquisitions, and expand OEM relationships, while retaining the existing management team (Greg Riemer as President & CEO). The company is actively investing in cleanroom capacity (multi-million-dollar expansions in both 2024 and 2026) and has added automation work centers to support ramp-up of new program wins scheduled for production in 2026.

Functional benefit

Products and services

• Design for Manufacturability (DFM) An early-stage engineering service that helps medical device OEMs design products for ease of manufacturing, improved quality, reduced cost, and shorter time-to-market. Involves a cross-functional team with design, quality, tooling, processing, and assembly knowledge.
• Silicone Molding, Plastic Molding & Extrusions Full-service injection molding of liquid silicone rubber (LSR), high consistency rubber (HCR), and thermoplastics, plus extrusion, conducted in ISO Class 7 and Class 8 cleanrooms using scientific molding techniques and SOLIDWORKS Plastics for moldability design.
• Multi-Material Molding Proprietary processes for molding dissimilar materials onto each other using chemical or mechanical bonding, combining the properties of both materials to enhance product integrity, reliability, and safety for medical device components.
• Finished Medical Device Assembly Total-solutions downstream service covering device assembly (including ultrasonic welding, pad printing, and mechanical assembly), sterile packaging, and sterilization management for finished FDA-registered medical devices.
• Global Supply Chain Development & Management End-to-end supply chain management service for medical device OEMs, including vendor managed inventory (VMI), MRP, ERP, EDI, LEAN principles, Kanban, and Just-In-Time delivery using IQMS/DELMIAworks ERP software.
