American Leistritz Extruder Corp. is using a new servo-motor and drive for its ZSE-18 co-rotating twin-screw extruder.
The brushless AC servo-motor is sealed against water sprays and dust. The motor also is much quieter than standard motors, according to the company.
Servo-motor technology facilitates a 1000:1 turndown, with a speed accuracy of .01 percent, making the extruder particularly beneficial in a laboratory that develops multiple products over a wide range of screw speeds, the company said.
Other features include segmented stainless steel screws on high-torque spline shafts, a torque rating of 72 NM, up to 1,200 screw revolutions per minute, modular stainless steel barrels with a tie-rod assembly for quick change, a gearbox positioning plate, quick connections for electrical and plumbing connections, a side stuffer and a stainless steel frame.
The ZSE-18 uses an Allen-Bradley controller.
The extruder is available for testing at American Leistritz's process laboratory in Somerville, N.J.
