Vacuum venting keeps molds running longer

Portable Mold-Vac evacuation systems from CAE Services Corp. help Infinity Molding double or triple the time between mold cleanings and also reduce rejects. The self-contained, stand-alone system pulls a vacuum on the vents during injection, and its patented air blowback function assist a in ejection and helps clean and purge the vents and ejector pins after every cycle. The blowback feature helps the tool to stay cleaner longer, and is a real benefit in extending time between cleanings. The microprocessor controlling both the vacuum and blowback functions receive a signal from the injection press. Infinity seals off a particular geometry in the part, or the entire mold, depending on the application.
