MRPC, a contract manufacturer of medical device assemblies and components based in Butler, Pennsylvania, has completed an 11-month, $3 million cleanroom expansion project. The expansion includes five new automated silicone molding work centers, facility infrastructure upgrades, robotics integration, and flashless molding technology to support growing demand from medical device customers.

Why it matters

The cleanroom expansion allows MRPC to consolidate operations into a contained, automated environment, minimizing overhandling and enhancing part cleanliness. This is crucial for customers in highly regulated and quality-sensitive industries like medical devices. The focus on flashless silicone molding also produces higher-quality parts, reduces contamination risk, minimizes waste, and lowers overall product costs.

The details

The new cleanroom space features seven cleanrooms supporting a blend of thermoplastic and silicone injection molding, transfer molding, extrusion, secondary operations and assembly. The automated silicone molding work centers, ranging from 130 to 150 tons, are designed for high-precision processing of liquid silicone rubber and high consistency rubber materials. The project also included facility infrastructure upgrades, robotics integration, and flashless molding technology.

  • MRPC completed the $3 million cleanroom expansion project over an 11-month period.
  • MRPC completed a separate $2 million cleanroom project in early 2024 for device assembly, packaging and other finished medical device assembly processes.

What they’re saying

“Automation ensures a stable and repeatable molding cycle. Robotics perform repetitive tasks with greater speed and precision, while integrated process monitoring systems continuously verify and control molding parameters and part integrity. If validated process limits are exceeded, the system automatically segregates product, protecting quality and maintaining consistency shot after shot.”

The takeaway

MRPC's cleanroom expansion demonstrates the medical device industry's ongoing focus on automation, precision manufacturing, and quality control to meet the stringent requirements of highly regulated markets. The investment in flashless silicone molding technology also highlights the company's commitment to sustainable manufacturing practices that reduce waste and lower costs for its customers.
