The advantages of the extruder rubber screw: the material of the extruder screw must have high mechanical strength, can withstand huge torque, and will not deform under high temperature and high pressure. The reason is that the screw element of the extruder rotates in the barrel under high temperature, high pressure and high torque. Because the material must be forced to move forward during the rotation process, and it must also withstand the strong friction and corrosion of the plastic decomposition gas, the extruder screw must have advantages in these properties.
The process of choosing the right screw and barrel combination for your plastic application is a critical part of the success or failure of any particular machine unit, and this cannot be overstated. However, most people may not realize that this selection process is often wrong or even incomplete.
Unfortunately, it is more frequent than you think. Hard data can be a bit elusive, because most companies are unlikely to track this particular metric. Just ask any experienced salesperson, and they are likely to think of 5 verifiable stories. It may not be as bad as it used to be in the industry, but in many cases, the barrel and screw are sometimes a secondary topic when buying a machine.
Buying a durable extruder has economic and quality advantages. First, such an extruder will require less regular maintenance, thereby saving production downtime and maintenance spare parts costs. In addition, the robust extruder can easily handle recycled or substandard materials, thereby saving raw material costs.
