Mold heat treatment process

Gummed occurred on the surface, as is known to all, wear, fatigue and fracture also tend to start from the surface, so the quality of mold surface processing requirements are very high. Surface strengthening main purpose is to improve the mold surface wear resistance, corrosion resistance, and lubrication performance. But in fact because of the existence of traces processing heat treatment the surface oxidation decarburization also unavoidable.
generally learn from mould failure analysis, 45% of die failure is due to improper heat treatment, the surface of the mold performance rather than matrix.
the new heat treatment technology is economic and effective to improve the performance of the mold of the important measures. Mold heat treatment process including matrix strength and surface treatment. The strength of substrate is to improve the strength and toughness of the matrix, reduce fracture and deformation. So the following heat treatment process must be done.
