The new 2500G2 continuous, in-line thermoformer from Sencorp Inc., Hyannis, Mass., is a heavy-duty unit for deep-draw packaging. It is claimed to be one of the first inline units to produce trim-in-place parts up to 12-in. deep. Another “first” for this machine is side-load sensors that automatically adjust chain-rail width based on sensing material stretch. This feature minimizes uneven material stretch and keeps the sheet flat. Chain rails are water-cooled.
The oven utilizes quartz and/or ceramic heating elements, which are profiled via the PLC controller. Also standard is Sencorp’s infrared thermal imaging scanner, which automatically scans sheet temperature and adjusts oven zone temperatures relative to preset recipes. The machine has a 100-ton, servo-driven, cut-in-place press with a 32 x 36 in. forming area, 13-in. stroke, 3.5-in. shut-height adjustment, and four hydraulic cylinders. A heavy-duty unwind stand has a roll lift that handles up to 2500 lb.
