How does PET injection molding machine work?
PET injection molding machines work by using a screw-type plunger to heat and melt the PET resin. The plunger then injects the melted plastic into a cooled mold, where the plastic solidifies into the desired shape. Once the plastic has solidified, the mold is opened and the finished part is ejected.
There are several key components of a PET injection molding machine, including the injection unit, the clamping unit, and the control unit. The injection unit is responsible for melting the PET resin and injecting it into the mold. The clamping unit holds the mold in place and applies pressure to ensure that the mold is properly filled and that the finished part has a good surface finish. The control unit monitors and controls the various functions of the machine, such as the temperature of the mold and the injection pressure.
