The shear performance of the extruder is determined by the screw structure of the extruder. However, the quality of extrusion and the efficiency of extrusion are also due to the compatibility of the extrusion process wit...
1. Thread forming: all are rolled (ie, "thread rolling" in other answers), and no turning is allowed, because the surface of the thread is more likely to have microscopic defects, which will have a large impact on...
The bending deformation of PVC profile is a common problem in the extrusion process. The main reasons are: uneven discharge of the die; insufficient cooling of the material during cooling and shaping, and inconsis...
The plasticizing device of the injection molding machine is generally equipped with an integral rotating mechanism. When assembling and disassembling the screw nozzle, screw and barrel of the injection molding mac...
In the processing of plastic products, many questions are often encountered. One of the common questions is that the screw of the injection molding machine is not fed. This kind of question: The screw is operating...
An injection molding machine usually has three screws to choose from, called A, B, and C screws, with small, medium, and large diameters. Their aspect ratios are about 22, 20, and 18. The screw length and the injection s...
