Advantages of low-pressure casting molds

This method can accurately control the filling process. Injecting molten metal in this way can reduce the formation of oxides and reduce porosity, ensuring excellent consistency from top to bottom. Therefore, low-pressure casting molds can produce excellent density and strength values, as well as excellent dimensional accuracy.

Factors to Pay Attention to in Gravity Casting Mold Production

In the actual production process of gravity casting, every link must be strictly controlled. Any mistake in any link can cause damage to the quality of the casting or even direct scrapping. Therefore, it is necessary to understand the areas that need to be paid attention to when producing gravity casting molds.

Application Analysis of Gravity Casting Mold

Gravity casting mold refers to the use of other easily formed materials to pre create the structural shape of a part in order to obtain its structural shape. The mold is then placed in a sand mold to form a cavity with the same structural size as the part. The liquid is then poured into the cavity, and after the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.
