The special welding wire is fused to the damaged part of the mold and the original substrate by laser instantaneous high heat. In the electric spark, grinding and other processing into a smooth surface, so as to achieve repair mold. To the mold sand hole, Angle collapse, crack, and wear and other small parts of the precision repair. Small heat affected area, will not cause precision mold deformation. The welding depth is large, the welding is firm, the melting is sufficient, does not leave the repair mark. There is no sag at the junction of the convex part and the matrix of the dissolved material.

Suitable for repair welding of medium and small moulds. Widely used in mobile phones, digital products, glasses, toys and other mold manufacturing and molding industry. All kinds of mold steel, stainless steel, cymbal steel, precious metal and very hard materials. Precision injection molding, die casting, mold repair metal accessories and accessories, precision stamping parts welding, lost wax casting, aluminum casting, stainless steel products sand hole repair.
