“For many industrial manufacturers, honing certain material compositions means putting production on hold to swap out hardware or pumps,” said Robert Delgado, global strategist and product manager for eMobility in Graco’s Industrial Division. “This is especially problematic for electric vehicle (EV) battery assembly and other applications, with constantly changing process requirements and technical specifications.”
While developing EVR technology, Graco also worked with material suppliers about the need to try different ratios and viscosities for research and development purposes, for example, when design engineers write product specifications.
“Whether it’s thermal interface material, epoxy, silicone, urethane or acrylic; two component material uses and requirements are always changing,” said Delgado. “To keep up, manufacturers and suppliers must make adjustments ‘on the fly’ and with minimal capital reinvestment.”
The high flow EVR can move up to 6,400 cubic centimeters (ccs) per minute, while flexing dispense ratios anywhere between 1:1 to 5:1 or 2:1 to 10:1.
When it’s time to try different material, the EVR’s base purge feature conserves the amount of solvent used to clean out the system by independently driving either material side. It also keeps old material from curing, so that there’s no need to replace a static or dynamic mixer because of fast curing materials or intermittent production runs.
