In some cases, die casting molds are defective. At this time, it is necessary to check the die-casting mold by some methods. What is the inspection process of die casting mold? Let us injection mold processing manufacturers take a look at the inspection process of die casting molds.
(1) Macro-corrosion inspection: mainly inspect the porosity, segregation, cracks, cracks, non-metallic inclusions, hammer cracks and joints on the surface of the material. (2) Impact resistance inspection: check the ability to resist crack expansion and extension, and avoid the overall cracking of the mold; (3) metallographic inspection of die-casting materials: check the segregation, distribution state, crystallization degree and grain size of carbides on the grain boundary of the material Inclusions, etc. are recommended for mold production. The microstructure determines the performance of the steel, not just the alloying elements. The finer the metallographic structure, the higher the impact energy. On the one hand, the metallographic structure depends on the characteristics of the material itself, and on the other hand, it depends on the heat treatment; (4) Ultrasonic inspection of the internal quality of the material: professional mold production and production know the defects and sizes inside the die-casting mold material, and find and avoid micro-cracks in time .
