After the screw barrel is used for a period of time, the screw edge and the nitrided layer of the barrel (when making a new screw, both the screw and barrel will be subjected to nitriding heat treatment, so there will be a nitride layer of about 30-60 filaments on the surface ) It is worn in both di... read more
How to maintain and repair the screw? ①It is not allowed to start the screw rotation when empty. Empty car inspection before driving? It should be started at low speed during trial operation, and the rotation time should be as short as possible (it should not exceed 2~3min. If everything is checked,... read more
During the extrusion process, the surface of the screw and the inner wall of the barrel are affected by material wear and corrosion. The gap between the two increases, which reduces the extrusion rate and seriously affects the service life of the machine. This article mainly introduces the measures ... read more

The close relationship between injection speed and product quality makes it a key parameter of injection molding. By determining the start, middle, and end of the filling speed segment, and realizing a smooth transition from one set point to another set point, a stable melt surface speed can be ensu... read more
