Plastic mold is a kind of plastic molding, extrusion, injection molding, blow molding and low foaming molding plastic mold. Including the die with variable cavity composed of concave mould substrate, die components and die combination lock plate, the convex die combination substrate, punch assembly, punch card, combination cavity blocking assembly and side cutting plate group...
What are the main processes in the manufacture of moulds?
1, the large section of the mold, steel hardenability is poor, such as the selection of a large mold of low hardenability steel. 2. In the original microstructure of die steel, the segregation of carbide is serious or the structure is thick. 3, the die forging process is not correct, after the forging did not stop very good spheroidizing annealing, so that the mold steel ball bad organization...
What is the reason for the formation of mold hardness with the lack of an average?
1, the large section of the mold, steel hardenability is poor, such as the selection of a large mold of low hardenability steel. 2. In the original microstructure of die steel, the segregation of carbide is serious or the structure is thick...
