The revised Alpha line of single-screw extruders from Battenfeld-Cincinnati (U.S. office McPherson, Kan.) are now equipped with a new, extremely compact drive system, which provides a smaller footprint while substantially reducing oil requirements. The extruder line, which is for pipe and technical profiles, also features a redesigned substructure, allowing for even more space savings.
The extruders also now feature built-in high-quality frequency converters for more accurate regulation of screw speed, torque, and temperature control. Temperature controllers are equipped with a fast self-tuning function and have an integrated on/off function as well. The new extruders are particularly user-friendly thanks to a warning light in traffic-light colors. The green light signals that the extruder is operating trouble-free, orange stands for conditions requiring the machine operator’s attention, red indicates a need for immediate intervention.
The Alpha line is available in the sizes alpha 45 (pictured) , 60 and 75 with either smooth-bore or grooved-feed zones.
