What do you mean by the "starting position and time" of the injection molding machine?.
When injection is converted to holding pressure, it is determined by time or position. If the location, the general set pressure holding position is about 5% of the storage position.
It's the way to switch from glue to pressure. See if it's a shot position, or time, or time + position.
Here's some advice to see if it will help you. Let's first understand the meaning of pressure and pressure. The injection pressure is the pressure applied to the material in the process of advancing. Keep the pressure, that is, after the glue is finished, continue to maintain a pressure. The rubber here is in principle not a force given by the feed. Thus, the position of the dwell pressure is determined by the fact that you are no longer positioned. The effect of holding pressure is to continue to give a force to prevent the return of the glue, so that the product is fuller. The position and time of holding pressure, the design of the machine is usually based on the location, and has not reached the set position of the pressure setting, it starts with the time after the completion of the injection glue.
