Collection of plastic injection mold repair methods

★ Padding method
Add a backing plate to the parts with serious wear on the large area plane, and then process to the original size for repair.
★ Surfacing method
The surfacing repair is to use low temperature argon arc welding, electric welding, brazing and other methods for surfacing and then repair.
★ Replace with new parts
This method is mainly applied to the repair of broken or severely worn movable parts such as rods and tubes of injection moulds.
★ Insert method
Cut the seriously worn or damaged part of the injection mold in a large area, and then make a new insert to insert the part.
★ Electroplating method
Use electroplating technology to make new inserts to insert the worn or damaged parts of plastic injection moulds.
★ Knocking method
For small and shallow scars on plastic injection molds, use a hammer to knock around or back to make up for the scars.
★ Grinding, grinding and polishing
This is a necessary method for plastic injection mold repair. This method is mainly used for repairing "bite" parts and surface rust removal.
★ Framed reinforcement
This method can be used to repair cracks in plastic injection mold when formed parts are subject to long-term alternating heat and stress.
★ Hole expansion method
When the fitting holes of various rods of plastic injection moulds are deformed due to sliding wear, the repair method of enlarging the hole diameter and correspondingly increasing the diameter of the matching rod is adopted.
★ Borehole column inlay method
When the parting surface and other parts of the plastic injection mold are damaged and cannot be repaired by knocking, it is necessary to consider the use of drilling insert column grinding for repair.
