American Leistritz Extruder Corp. is calling its personal-computer-based controller for twin-screw extruders, the Macromatex TSCS.
The system, with Windows 2000 software, eliminates the need for a programmable logic controller and discrete temperature controls. Auto-tune temperature control for the barrel sections and die is performed within the PC software itself.
The operator uses a keyboard or a touch screen, or both.
Leistritz, headquartered in Somerville, N.J., said the controller can store an unlimited number of recipes. It also easily exports run information into a spreadsheet.
The TSCS can be retrofitted onto existing Leistritz twin-screw extruders.
