简体中文The working surface of the bimetallic screw barrel has a hard protective coating (usually 1-2 mm thick), which enables manufacturers to extrude pipes of difficult-to-process materials while providing a lasting and reliable production experience.
Using recycled plastics or unqualified plastics to produce plastic pipes may cause damage to the extruder. When buying a new extruder, your best choice is to choose an extruder with a bimetallic screw barrel, because it allows you to use a series of cost-saving materials, such as recycled plastic or unqualified plastic, without sacrificing the health of the extruder machine.
Bimetal screw barrels can achieve the best extruder performance, strength, fatigue resistance, and enhanced process control. During the whole service life of the extruder, several factors will bring extra pressure to the extruder, and the following are the most important factors.
Buying a durable extruder has economic and quality advantages. First of all, such an extruder will require less regular maintenance, thus saving production downtime and the cost of maintaining spare parts. In addition, a solid extruder can easily handle recycled materials or unqualified materials, thus saving raw material costs.
Extruder is the core of the pipe production line, which has a greater influence on the quality of finished products than any other machinery. If properly operated, high-quality extruders usually require less maintenance, thus reducing production downtime, replacing parts, and energy consumption, and allowing you to use recycled materials or unqualified materials without causing damage to finished products or extruders.
