At present, with the continuous development of plastic mold industry, the application of plastic mold steel is also increasing. And a good plastic mold needs not only the quality of plastic mold steel, but also the detection test, so that the plastic mold steel is really high quality plastic mold steel. Last time, Xiaobian has taught you how to identify the quality of plastic mold steel, so this time, let's teach you how to jinan test the plastic mold steel?
