How to deal with the plastic injection molding raw material is not filled?
Electric injection molding machine in the production of injection mold will encounter the situation of injection molding is not filled, there is a lack of glue at the bone position right Angle and fuse connection, here to share some experience.
Analysis of glue injection is not filled:
1. The trapped air in the bone position makes the injection molding machine fill up.
2. The filling of the injection molding machine caused by the glue welding line is not filled.
Reason analysis of glue injection is not filled:
When the injection molding machine is working, the mold gluing method is two-point gluing, and the injection speed is too fast, which is easy to cause the gas trapped at the right Angle of the bone position and cause the filling dissatisfaction; If the injection speed is too slow, it is easy to fill the fuse at the end of the flow.
The solution:
Multistage injection molding and position switching.
In the first stage, the medium speed filling channel was used to pass through the glue inlet and switch the position; then, the second stage was used to quickly fill the vicinity of the bone site and switch the position; the third stage was used to slowly fill the bone site to discharge the gas; finally, the speed filling was used to switch the pressure holding position and the pressure holding time was extended appropriately.
