What is the reason for the deformation of castings in gravity casting machines?

      The main structure of the Gravity Casting Machine includes five types: main lifting cylinder, turning cylinder, lower lifting and unloading module, turning module and clamping module. The circuit system of the gravity Casting Machine is composed of PLC control mechanical equipment and industrial touch screen, which effectively ensures the reliable operation of the mechanical equipment and improves the reliability of the system. The structure of the gravity casting machine determines its good application effect in actual use.

　　Gravity casting machines can produce various complex castings. Due to the increase in tilt speed during the pouring process, the mold is exhausted and the molten metal is filled more quickly, effectively improving product quality and casting qualification rate.

 

　　When manufacturers are in a hurry for production, some unexpected things sometimes happen. One of them is the deformation of castings produced by gravity casting machines. To solve the problem of casting deformation, we must first know the causes and causes of casting deformation, so as to fundamentally avoid the problem of casting deformation.

 

　　In fact, casting deformation is the result of gravity casting stress. When the casting stress generated during the cooling process is greater than the yield strength and tensile strength, the casting will deform or crack during storage or use. Simply put, the gravity casting machine gives the casting an unbearable force, making it unable to withstand deformation.

 

　　But don’t worry, the deformation of castings can generally be corrected. For example, steel, non-ferrous metals, ductile iron, and even some gray cast iron can be corrected mechanically, during heating or heat treatment. In production, try to make the casting structure reasonable, use reverse deformation to properly control the stress of the casting, and avoid casting deformation as much as possible during the production of the gravity casting machine.
