    塑胶模具钢材镜面加工性能的影响因素有哪些吗?

    来源:https://www.jnqhmj.com/ 日期:2021-05-26 发布人:admin


    镜面加工性能,是塑胶模具钢材中的一种加工性能,因为有些模具对于成型的抛光的要求较高,因此在选择模具钢材的时候,对于镜面加工性能也有一定的要求。若是塑胶模具钢材镜面加工性能不好,则会影响到模具的使用,那么你知道塑胶模具钢材镜面加工性能的影响因素有哪些吗?
    Mirror processing performance is a kind of processing performance of plastic mold steel, because some molds have higher requirements for molding and polishing, so when choosing mold steel, there are certain requirements for mirror processing performance. If the mirror processing performance of plastic mold steel is not good, it will affect the use of the mold. Do you know the influencing factors of the mirror processing performance of plastic mold steel?
    塑胶模具钢材镜面加工性能的影响因素,主要有以下方面:
    The main influencing factors of mirror processing performance of plastic mold steel are as follows:
    1、硬度:
    1. Hardness:
    塑胶模具钢材的硬度大小,会在一定的程度上影响镜面加工。因为高硬度有利于镜面抛光,例如像一些塑胶模具钢材,由于在抛光过程中,表面接触应力过高,在热处理后表面出现渗碳或脱碳的话,会导致表面质量恶化,从而影响抛光性能。
    The hardness of plastic mold steel will affect the mirror processing to a certain extent. Because high hardness is conducive to mirror polishing, such as some plastic mold steel, due to the high surface contact stress in the polishing process, carburization or decarburization on the surface after heat treatment will lead to the deterioration of surface quality, thus affecting the polishing performance.
    2、冶金质量:
    2. Metallurgical quality:
    塑胶模具钢材在生产的过程,一般都需要经过冶炼、铸造、锻造……等工序后才可以成材,而由这些工艺过程控制的质量,就称为冶金质量。通过这些工艺后,就可以有用地提高钢的纯净度及其抛光性能。
    Plastic mold steel in the production process, generally need to go through smelting, casting, forging... And other processes before it can be made, and the quality controlled by these processes is called metallurgical quality. Through these processes, the purity and polishing performance of steel can be effectively improved.
    3、组织不均匀度:
    3. Inhomogeneity of microstructure:
    塑胶模具钢材的组织不均匀度,主要是指显微偏析的影响。若是想消 除影响,就要掌握好出出钢后的浇注技术和钢锭的结晶质量,充分锻造,对塑胶模具钢材进行均热化处理或ESR,以其来保证它的致密度。
    The inhomogeneity of plastic mold steel mainly refers to the influence of microsegregation. If you want to eliminate the influence, it is necessary to master the pouring technology after tapping and the crystallization quality of ingot, fully forge, and homogenize or ESR the plastic mold steel to ensure its density.
    以上所介绍的内容,就是塑胶模具钢材镜面加工性能的影响因素。但是,由于影响塑胶模具钢材镜面加工性能因素较多,因此,在实际过程还是需要根据塑胶模具钢材所采用的材质以及其他方面来进行判断。
    The content introduced above is the influencing factors of mirror processing performance of plastic mold steel. However, there are many factors that affect the mirror processing performance of plastic mold steel, so in the actual process, we still need to judge according to the material used by plastic mold steel and other aspects.
