W&H announces its latest technological achievement in blown film extrusion, the EASY CHANGE automatic job setting system. Available for use with W&H’s VAREX® blown film extrusion equipment, EASY CHANGE automatically configures new job change parameters at a much faster rate and more efficiently than with a traditional manual changeover. EASY CHANGE is capable of automatically adjusting to new target values the following job parameters in blown film production: * Film width * Film thickness/ layer distribution * Output * Cage height A recent demonstration at W&H’s Extrusion Technology Center showed a product changeover completed in under 3 minutes using EASY CHANGE’s automatic adjustment features that manually would have required 15 minutes to execute. Besides increased uptime, EASY CHANGE also accounts for significant resin savings and reduced energy consumption given a company’s specific product structure. EASY CHANGE is available as an option on all new VAREX® blown film lines, and also as a retrofit for VAREX® lines equipped with the PROCONTROL® TS operation system.
