In the injection molding process, it is important that the ejection force does not lead to any deformation of the plastic part.
A stripper plate is distributing the applied demolding force from the machine homogeneously along the contact surface and keep the molded part in a defined position during ejection.
Damage of the part as well as marks on the part will be avoided in this way.
Preferably for parts with a deep core, this method is used.
