MRPC has completed a cleanroom expansion and automation project at its headquarters in Butler, Wisconsin.

The move by the US-based manufacturer is aimed at increasing production capacity and advancing its silicone moulding capabilities for the medical device sector.

The expansion adds approximately 10,000 sqft of cleanroom space at the Butler facility, purpose-built to support advanced silicone moulding operations in a tightly controlled environment. 

As part of the upgrade, the expanded cleanroom now incorporates multiple automated silicone moulding work centres, alongside robotics integration and facility infrastructure improvements. 

The inclusion of high-precision automated systems enables more consistent output while reducing the risk of contamination and variability.

The additions also enhance process efficiency, repeatability and scalability across production lines.

MRPC’s Butler HQ facility historically maintained ISO Class 7 and ISO Class 8 environments for medical device manufacturing

The project was completed within MRPC’s existing footprint, with no external cleanroom contractor publicly listed.
