Several Factors Affecting Die Casting Process

(Summary description)Due to the high melting point of some alloys, the service life of the matching die-casting mold is too low and the cost is high, which is difficult to apply in actual production.

1. Limiting factors of die-casting alloy types:
Die casting molds are limited by operating temperature. Due to the high melting point of some alloys, the service life of the matching die-casting mold is too low and the cost is high, which is difficult to apply in actual production. At present, the alloys used in die casting production are mainly non-ferrous metals such as zinc alloy, aluminum alloy, magnesium alloy and copper alloy.

2. There are often pores on the surface of die castings:
The gas expansion in the pores at high temperature will cause bubbles on the surface of the die casting, which will seriously affect the appearance of the die casting and reduce the overall quality of the zinc alloy die casting. Therefore, die castings generally cannot be heat treated and welded, nor should they work at high temperatures.
3. Restriction of die casting size:
The size of the die-casting mold is limited by the clamping force of the die-casting machine and the size of the mold, so the die-casting process is only suitable for the production of small and medium-sized castings, but not suitable for large-scale castings. Likewise, for die-casting parts with complex concave surfaces, die-casting production is also more difficult due to the limitations of die-casting molds and principles.
