1) The mold temperature is too low, the internal structure of the casting is loose, the air discharge is difficult, and it is difficult to form.
2) The mold temperature is too high, the internal structure of the casting is dense, but the casting is easy to be "welded" attached to the cavity, and the mold is difficult to discharge the casting. At the same time, too high a temperature will cause the mold body to expand itself, affecting the dimensional accuracy of the casting.
3) The mold temperature should be selected within the appropriate range. Generally, after the test is appropriate, the constant temperature control is good.
