The general purpose screw is generally divided into three sections: the feed section, the compression section, and the homogenization section, which are matched by a complete set of barrels. First of all, we must confirm the parameters: the commonly used parameters such as the aspect ratio, the comp... read more
There are probably several reasons: 1. Too much recycled material is added to the plastic. 2. The screw and barrel are covered with glue-plastic wraps the screw and rotates together. 3. The screw and the barrel are worn out, or the abrasion of the rubber ring causes the plastic to leak and not be tr... read more
The molding process of the screw and barrel is: first add granular or powdered plastic into the barrel, and turn the screw and heat the outer wall of the barrel to make the plastic into a molten state, and then the machine closes the mold and moves the injection seat forward to make the nozzle Close... read more
Reasons for screw wear caused by bimetallic screw and methods to reduce wear 1. Each plastic raw material has an ideal plasticizing processing temperature range, so the processing temperature of the barrel should be controlled to make it close to this temperature range. Granular plastic enters the b... read more
In the past three years, in order to improve the wear resistance and corrosion resistance of the screw and barrel of the rubber extruder, our company has made great progress in the research on the corrosion resistance of the screw and barrel. The main manifestations are: The development of new mater... read more
