Precautions for die-casting forming conditions
2023-06-08
Die casting machines, die-casting alloys, and die-casting molds are the three essential elements of die-casting production, and none of them are indispensable. The so-called die casting process is the organic and comprehensive application of these three elements, so as to produce qualified castings with good appearance, internal quality, and dimensions that meet the requirements of the drawing or agreement in a stable, rhythmic and effective manner, and even excellent castings.
Material melting temperature, mold temperature during injection molding, and melt temperature;
Then, the condition of the die-casting product needs to be adjusted in order to obtain a complete product. The selection principle of working temperature for die-casting molds:
1) The mold temperature is too low, the internal structure of the casting is loose, and it is difficult to discharge air, making it difficult to form;
2) The mold temperature is too high, and the internal structure of the casting is dense, but the casting is prone to "welding" and sticking to the mold cavity, making it difficult to remove the casting. At the same time, excessively high temperatures can cause the mold itself to expand, affecting the dimensional accuracy of the casting.
3) The temperature of the mold should be selected within an appropriate range. Generally, after appropriate testing, constant temperature control is preferred. The precautions for die-casting forming conditions can be simply summarized into the following two aspects:
*Material melting temperature, mold temperature during injection molding, and melt temperature;
