厂家常见的压铸件表面缺陷之一，厂家对于把这种常见的缺陷都会有一套实用的预防方案，进而生产出优质的压铸件产品，那么网状毛刺是什么引起的呢？ Die-casting mesh burrs are one of the common surface defects of zinc alloy die-casting manufacturers. Manufacturers will have a set of practical preventive measures against such common defects, and then produce high-quality die-casting products. What is the net-shaped burrs? What caused it? Please see below.
厂家从生产经验上总结出引起这种压铸件表面不符合要求的原因有以下七种：压铸模型表面龟裂；压铸模材质不符合要求或者成熟处理工艺不正确；压铸模冷热温差变化太大；浇注温度过高；压铸模预热不足；型腔表面粗糙；压铸模壁薄或有尖角。 Zinc alloy die-casting manufacturers have summarized from production experience the following seven reasons that cause the surface of such die-casting parts to not meet the requirements: cracks on the surface of the die-casting mold; the material of the die-casting mold does not meet the requirements or the mature processing technology is incorrect; The change is too large; the pouring temperature is too high; the die-casting mold has insufficient preheating; the surface of the cavity is rough; When the manufacturer finds that there are net burr defects in the die-casting product, then it is necessary to determine which surface defect caused by the cause, and then take the corresponding solution. Of course, for senior die-casting manufacturers, they Relying on your own experience and advantages to quickly find out the cause, greatly saving time.
厂家对于压铸件网状毛刺是如何解决这一难题的呢？ How do zinc alloy die-casting manufacturers solve this problem for the net burr of die-casting parts? First of all, they correctly choose the die casting mold material and heat treatment process when die casting, and control the pouring temperature in place during pouring, neither too high nor too low, especially for high melting point alloy molds, they will carefully preheat to ensure that Preheating is sufficient. Secondly, the die-casting mold is annealed periodically or after a certain number of times, and the surface of the formed part is polished.
