The influence of position control on product quality during injection molding
June 28, 2022
Position control: Some injection molding machines have mold shift position, die position, stock storage and injection position control.
The position of the mold is from the mold opening to the closed mold to lock the entire moving distance called the mold shift position. The best position for mold shifting is to remove the product smoothly. The mold opening distance is too large and the molding cycle is long.
The position of the die can be easily removed by simply controlling the position of the die from the mold.
Storage position: Firstly, the amount of plastic injected in one time of the molded product should be ensured, and secondly, the amount of storage in the barrel should be controlled. The storage position control is more than one injection, and the product is easy to fly, and the product is insufficiently formed.
The amount of material stored in the cylinder is too much, the plastic stays in the barrel for a long time, the product is easy to fade, and the strength of the molded product is affected. On the contrary, it affects the quality of plastic plasticizing, and it is not added to the mold during the pressure keeping, and the product is not formed with dents.
