Precision Engineering • OEM-Level Rebuild • Performance Optimization

Reliable blown film production depends on dies and die plates running at exact tolerances. Heat imbalance, contamination, wear, and flow restriction reduce output and film quality. Industrial Maintenance Rebuilders (IMR) provides complete OEM-grade repair, rebuild, and flow-path optimization for all makes and models of blown film dies and die plate systems.
