件表面缺陷的表现形式之一，那么压铸件冷豆缺陷是怎么产生的呢？ Cold beans are one of the manifestations of the surface defects of zinc alloy die- castings. So how do cold-bean defects of die-castings occur? Production experience summarizes that cold beans are embedded on the surface of die-casting parts and metal particles that are not fully fused with the casting are called cold beans, which are usually produced in under-cast places. Cold bean defects will occur in the cavity.
厂家时如何进行有效预防的呢，首先厂家要根据具体情况分析引起冷豆缺陷的原因到底是哪一种再进行预防，通常预防的方法有改进浇注系统，避免金属型芯、型壁增大内浇道截面积，或者改进操作，调整泵机器等，从而达到预防的效果。 For cold bean defects, how can zinc alloy die-casting manufacturers effectively prevent them? First of all, manufacturers must analyze the causes of cold bean defects according to the specific situation and then prevent them. The usual prevention methods include improving the pouring system to avoid metal. The core and wall can increase the cross-sectional area of the runner, or improve the operation, adjust the pump machine, etc., so as to achieve the effect of prevention.
过程中遇到的产品缺陷，厂家并不是完全根据书本描述或者知识点描述来预防的，通常都要结合缺陷的程度和厂家的实际操作来进行判断的，故而这就需要讲到厂家的经验了，因为厂家的经验决定着能否快速有效的做出预防的措施。 For product defects encountered in the zinc alloy die casting process, manufacturers do not completely prevent them based on book descriptions or descriptions of knowledge points. Usually, they must be judged by combining the extent of the defects and the actual operation of the manufacturer, so this needs to be mentioned The experience of the manufacturer, because the experience of the manufacturer determines whether the preventive measures can be taken quickly and effectively.
