Talking about the factors affecting the quality castings

Product quality has a direct impact on its use effect. Poor product quality may cause many follow-up problems, especially die-casting products. Do you understand the factors that affect the quality of die-casting products? Based on many years of industry experience, magnesium alloy die casting manufacturers will introduce you from the following aspects.

1. Mold temperature

The temperature of the mold is an important factor affecting its quality. If the temperature is not appropriate, it will not only affect the internal and external quality of the die-casting, but also affect the accuracy of its size and even cause deformation, causing cracks or cracks on its surface. The formation of network burrs that are difficult to remove, thereby affecting the appearance quality of the die casting.

2., the determination of the size of the molded part

When calculating the size of die-casting parts, the shrinkage rate of die-casting materials should be selected to be in line with reality, otherwise the product will be unqualified.

3. The location of the parting surface

The position of the parting surface will directly affect mold processing, exhaust, and product demolding. Thermal oil heaters usually leave a trace on the parting surface of the product, which will affect the surface quality and dimensional accuracy of the product. Therefore, when designing the position of the parting surface, in addition to the product release, mold processing, exhaust and other issues, the parting surface position can be placed where the product surface quality is not high or the dimensional accuracy is not high.

4, the mold cannot be deformed

Generally, due to the unreasonable mold structure or improper selection of mold materials, the heat-conducting oil oiler will cause the mold to crack and deform during use, resulting in unreasonable products.
