The principle of surfacing technology is to weld the filler metal to the damaged part of the plastic mold surface. Butt welding technology is widely used in the plastic mold industry, which effectively improves the performance and life of the mold, reduces production costs, improves work efficiency, and prevents cracks in the mold, ensuring the stability and quality of the mold.

It is inevitable to perform trimming during the mold manufacturing process. The materials used must have good surfacing processability. After the hot forging mold has been used for a period of time, the cavity is worn or even deformed, affecting the dimensional accuracy. Surfacing technology is needed for repair.

Plastic mold

1. The flange of the mold is worn, deformed, cracked, etc., resulting in the failure of the mold to be used. Using surfacing technology to repair all the damaged parts of the mold can effectively increase the service life of the mold and improve the plastic deformation and wear resistance of the mold.

2. When there is a chipping at the edge of the punch and die, use the same welding rod as the chipping base material for surfacing, and then process according to the dimensional accuracy requirements of the drawing

3. When the edge of the cavity is bumped and notched, the repair method can be used. The repair is completed by the fitter using argon arc welding. The rule for extrusion and expansion repair is to drill holes near the notch, and the side walls of the extrusion cavity are trimmed by fitters, and the plugs and parting surfaces should be flattened.

Fourth, the surfacing processability of hardened mold steel is relatively poor. During processing, it is easy to cause cracks in the mold steel due to the too fast cooling speed. Therefore, when welding hardened mold steel, a tempering furnace should be prepared to facilitate preheating of the mold in advance.
