Berstorff brings out new ZE twin screws
Berstorff Corp. has added two twin-screw extruders to its ZE Series, the ZE 110 and ZE 155, rounding out its offering.
The ZE 110 fits between Berstorff's ZE 90 and ZE 130. The extruder features splined shafts to boost torque and transit the torque over a larger surface area, working at speeds as fast as 600 revolutions per minute. Also available: A higher-speed version that can run at 1,000 rpm.
For extruding heat-sensitive products, the ZE 110 offers high-torque, high-throughput extrusion at low speeds necessary to maintain low temperatures.
The ZE 110 comes in two configurations, ZE Ultra Torque and ZE 110-R, which has 70 percent higher volume for reactive processes.
The ZE 155 has a round shaft. It can run at 350 rpm.
Berstorff is based in Charlotte, N.C.

Ceramic lining gives barrels longer life
General Plastex Inc. has introduced a ceramic-lined barrel that the Barberton, Ohio, firm said can greatly increase barrel life.
Tests on the new ceramic-lined barrels show their lifespans are as much as 30 percent longer that barrels made from conventional materials.
General Plastex said they are most effective when running highly abrasive or highly corrosive materials. The barrels can be used in injection molding, extrusion and extrusion blow molding machines. General Plastex makes new screws and barrels and retrofits old ones.
