Consistent output starts with a consistent machine. For low pressure molding operations, that means staying ahead of maintenance.
LPMS USA is highlighting the critical role routine equipment maintenance plays in long-term process stability. In low pressure molding applications, carbon buildup and material degradation can gradually accumulate in melt tanks, hoses, and system components during normal operation. Left unmanaged, that buildup leads to shot inconsistency, cosmetic defects, and unplanned downtime.
How Often Should You Be Cleaning?
LPMS recommends purging and cleaning low pressure molding systems every 80 to 300 hours of heat cycles, depending on production volume and material usage. Higher-throughput operations will need to clean more frequently.
The Right Tool for the Job
LPMS offers SPECTRA-MELT® OMEGA PURGE 200 and 225, thermoplastic polyamide purge materials engineered specifically for low pressure molding equipment. These materials provide a controlled purge process that removes carbon particles and residual material without disrupting flow consistency.
“Customers often focus on the molding process itself, but the condition of the system plays a major role in production consistency. Preventive maintenance is one of the simplest ways to improve part quality, reduce variability, and maximize machine uptime.”
— Brian Betti, LPMS USA
