Die-casting machine, die-casting alloy and die-casting mold are the three major elements of die-casting production, and none of them can be missing. The so-called die-casting process is to organically and comprehensively use these three major elements to stably, rhythmically and efficiently produce qualified castings with good appearance and internal quality and dimensions that meet the requirements of the drawings or agreements, or even high-quality castings.
Material melting temperature, mold temperature during injection and melt temperature;
Finally, the condition of the die-cast product must be trimmed to obtain a perfect product. Principles for selecting the working temperature of the die-casting mold:
1) If the mold temperature is too low, the internal structure of the casting is loose, the air is difficult to discharge, and it is difficult to form;
2) If the mold temperature is too high, the internal structure of the casting is dense, but the casting is easy to "weld" to the mold cavity, and the sticky mold is not easy to remove the casting. At the same time, too high a temperature will cause the mold body itself to expand, affecting the dimensional accuracy of the casting.
3) The mold temperature should be selected within an appropriate range. Generally, after testing, constant temperature control is better.
The considerations for die casting conditions can be simply summarized into the following two aspects:
* Material melting temperature, mold temperature during injection and melt temperature;
