RJG Inc. is getting small.
The Traverse City, Mich.-based RJG has introduced a 6-millimeter cavity pressure sensor, and the company claims it is the smallest injection molding pressure sensor of its kind. The sensor is ideal for high cavitation molds with small, tightly-packed ejector pins, the company said.
RJG is offering two models, one rated to 50 pounds for use with ejector pins up to 2 mm in diameter. The other is rated to 250 pounds, for pins up to 4.5 mm in diameter. The 50-pound model was available on April 3 and the 250-pound model will be available in the coming months.
The small sensor pressure sensor works together with RJG's eDart system to help molders diagnose the molding process and automatically sort bad parts.
“Smaller sensors are becoming more popular as part complexity and cavitation increases,” said Mike Groleau, project manager at RJG. “Our new sensor provides an alternative to the current Piezo technology that reduces costs while improving data reliability.”
The 6-mm sensor is part of RJG's Multi-Channel Strain Gage sensor line, which was designed to simplify in-mold installations for molds with four or more sensors and save space in the mold. That multi-channel cavity pressure solution allows injection molders to connect up to eight strain gage sensors to one connection point on the mold.
