What is the cause of material leakage on the side of injection mold?
The tensile strength of the connecting bolts in the injection mold is not enough, and it deforms under high temperature conditions, causing the melt to extrude from the joint end face of the mold parts.
Parliamentary mould parts are improperly assembled and the binding surface cannot be tightened.
Machining precision and surface roughness of integrated end face of machining tool parts.
Hydraulic connection bolts are not balanced in force.
Flow resistance of materials in the mould is high or the part of the mould lip (mouth mould) is blocked, causing the melt to extrude from the side.
After the bearing mold heats up to a constant temperature, the connection bolts should be tightened again.If the bolts are not tightened again, the bonding strength of the mould parts will be insufficient, and the melt will be extruded from the joint surface of the parts.
