Graham upgrades Revolution MVP rotary wheel blow molder

Revolution MVP Setups for Graham Engineering’s rotary wheel blow molding machine — the letters stand for Modular Variable Pitch — are configurable with 12 to 24 stations, with up to 10 extruders of different sizes in dual-parison setups. 

What’s new? Retrofittable packages that can improve maintenance and the machine’s ability to process post-consumer recyclate (PCR). Available since last year, Total Process Control, for processing PCR, takes advantage of a melt pump that’s added between the extruder and flow head. Meanwhile, the new Preventive Maintenance package, available this year, uses sensors installed in the wheel to provide data for a subscription maintenance service. 

Benefits Precision and flexibility, and with the newest software packages, the ability to enhance packages’ sustainability, and more effective preventive maintenance. Total Process Control allows for the use of more PCR or regrind. It ensures precision wall thickness and provides parison control, and counteracts the variability in bulk density and viscosity that manufacturers often experience when they use PCR and regrind, cutting variation limits in half. The Preventive Maintenance package supports earlier detection of performance changes and component wear.
