What should I do if the filling of plastic injection raw materials is not satisfied?

The electric injection molding machine will encounter dissatisfaction with the injection molding during the production injection molding process, and there will be a lack of glue at the right angle of the bone and the welding line. Here I will share some experience with you.

Analysis of the situation of dissatisfaction with glue injection:

Bone trapped air makes injection molding machine not full

Insufficient filling of the injection molding machine caused by the glue and weld line

Analysis of the reasons for dissatisfaction with glue injection:

When the injection molding machine is working, the injection method of the mold is two-point injection. The injection speed is too fast, which is easy to cause the air trapped at the right angle of the bone to cause dissatisfaction;

Solution:

Adopt multi-stage injection molding and position switching.

The first section fills the flow channel with a medium speed and passes through the glue inlet, switches the position, then the second section fills the vicinity of the bone position with a fast speed, and switches the position, and the third section fills the bone position with a slow speed to discharge the gas, and finally fills quickly, and switches to the safety position. Press the switch position and extend the holding time appropriately.
