Precision Machining High-Performance Polyurethanes
Machining cast polyurethane requires a thoughtful approach due to its unique material properties, especially its low thermal conductivity and elastic memory. These characteristics can lead to heat buildup and dimensional changes during machining, if not properly managed. Harder formulations (above 70 Shore A) can be machined using conventional metalworking techniques, while softer grades require alternative methods like grinding, sanding, or cryogenic processing. Precision fixturing, tool geometry, and cooling strategies are essential to maintain part integrity and dimensional accuracy.
Turnkey Solutions from MPC:
- Material Expertise: We understand how durometer, formulation, and part geometry affect machining outcomes
- Specialized Equipment: Proper tooling, fixturing, and cooling systems are essential to avoid distortion and surface damage
- Efficiency & Speed: Our experienced team streamlines post-molding workflows, reducing lead times and minimizing rework
- Consistent Quality: Tight process controls ensure repeatability across batches, critical for product performance
Case Study
A global OEM in the food processing equipment industry turned to MPC after persistent quality issues with a no-crush wheel were disrupting their production line. The molded components from their previous supplier lacked the precision needed for consistent system performance, leading to frequent downtime and costly maintenance. MPC’s engineering team reimagined the manufacturing approach, integrating precision machining to create critical features that couldn’t be reliably molded. This innovation not only eliminated the performance issues but also enhanced durability and alignment within the system-keeping the OEM’s operations team running smoothly and restoring confidence in their equipment reliability.
