Mr. Chen’s plastic mold core is a thin sheet, which is 6mm high but only 6mm thick. Now using 718H mold steel, it is easy to deform. It deforms after making thousands of pieces, and the parts are scrapped too quickly. What mold steel should be used to solve this problem?
A component, which is both drilled and shaped like a gong, is deformed and scrapped after only a few thousand times of production. Mold steel, no matter how cheap it is, has a high cost. Not only is the processing fee expensive, but the replacement cost is also high. If you keep stopping the machine for replacement, the plastic raw materials wasted in the material barrel will be a lot of money. Moreover, if you have to adjust the machine, the cost of delay will be several times that of mold steel. Therefore, for small parts, as long as the mold steel is useful and has a long service life, mold steel, no matter how expensive it is, is still cheap.
A 6mm thin plastic mold core may deform when the hardness is low, and break when the hardness is high. I recommend LG mold steel with high toughness.
LG is a high toughness mold steel exclusive to Yuhui Mold Steel. LG’s toughness is 8-9 times that of DC53, with a hardness of HRC54-58. Its toughness is so good that it does not break even when bent. Similar to thin sheet working conditions, there have been a large number of successful cases, so you can use it with confidence.
