Single screw extruder to meet the needs of high speed and high production. Equipped with a cylinder heater, the extruder can be heated in a very short time, the high heating temperature up to 450℃; The cooling design realizes the reverse flow cooling and cooling system. Equipped with the "bow clamp device", the replacement barrel time is faster than the traditional bolted type; The machine barrel adopts the process with high frequency quenching and hardening, which endowing the wear resistance, thus eliminating the need for wearing bushing. In addition, it is equipped with the company's process control system. In terms of functions, extruders are no longer limited to the formation and mixing of polymer materials, and their applications have been expanded to food, building materials, packaging, pulp and ceramics and other fields. In addition, the "one-step direct extrusion process", which combines mixing granulation and extrusion process, is also very attractive.
