Although the computer-controlled injection speed segmented control system has long existed, the advantages of this machine sets are rarely used due to the limited information. This article will systematically explain the advantages of applying multi-speed injection molding, and briefly introduce its use in eliminating short shots, trapped air, shrinkage, and other product defects.
Proportional control of injection speed has been widely adopted by injection molding machine manufacturers. Although the computer-controlled injection speed segmented control system has long existed, the advantages of this machine sets are rarely used due to the limited information. This article will systematically explain the advantages of applying multi-speed injection molding, and briefly introduce its use in eliminating short shots, trapped air, shrinkage, and other product defects.
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 to achieve a smooth transition from one set point to another set point, a stable melt surface speed can be ensured to produce the desired molecule and the smallest internal stress.
We recommend the following speed segmentation principle:
1) The velocity of the fluid surface should be constant.
2) The fast injection should be used to prevent the melt from freezing during the injection process.
