The welding material of plastic mold is the most basic condition and the most critical part for welding repair. According to different mold materials and mold welding repairs in different heat treatment states, the most suitable welding material should be selected.

For welding of molds in the annealing state and not yet heat treated, the material and the parent material need to be as similar as possible to avoid cracking during the heat treatment process, which affects the performance. General welding materials should have good tempering resistance and thermal fatigue resistance, and maintain a high hardness after welding.

For molds that have been heat treated, when welding repair, it is necessary to consider that the welding structure can meet the performance requirements of the mold. Generally, welding materials with excellent high temperature performance are used. Even if some materials have different compositions from the parent material, the performance after welding repair is even better than that of the parent material.

Plastic mold

High-temperature areas, diverter cones and other special parts and components of the mold require the use of high-alloy hardness welding materials. While the hardness meets the standard, it must also have good resistance to aluminum alloy erosion.

Preparations that must be made before welding: Cracks and cracks on the mold surface must be removed in time. If the welding groove is a narrow groove, it is very unfavorable for the quality of welding, so the groove needs to be rounded. The reason why pores appear in the weld is that there are a lot of impurities, oxides and oil stains at and around the welding position, which need to be cleaned up as soon as possible.
