Gravity casting is a metal casting process. There are many kinds of casting methods, and there are many places to use, such as automobile parts, motorcycle parts, motor parts and so on. Many places have good casting methods for us.

 

 

When gravity casting works, we must do a good job of fire prevention measures in the workshop, because red castings and spattering hot metal, once touched the human body, will be scalded; once touched with flammable or explosive materials, the consequences are unimaginable. And in the production process a little careless, there may be melted liquid metal scald. Accidental contact with high temperature castings can also be scalded. The operation of machinery and equipment in the casting process needs to be standardized in order to avoid the occurrence of errors or abnormal operation accidents. In addition, before driving, a comprehensive inspection is needed. Only after the confirmation of normal operation can the grinding machine be used. After the grinding machine starts, it is not allowed to pick up materials by hand and clean up the grinding wheel, and it is strictly forbidden to take sand samples on the grinding plate by hand.

 

The sand box stacking for gravity casting moulding should prevent collapse and injury. The total stacking height should not exceed 2m. When using pit moulding, we should know the water level of the moulding part of the pit, in order to prevent the explosion of high-temperature metal liquid in dampness during pouring, and we should arrange the exhaust passage so that the gas at the bottom of the mould can be discharged smoothly.

 

Gravity casting requires timely cleaning of equipment after work is finished.

 

 

Gravity casting needs to clean up the equipment in time after the work is finished, and do a good job of protection when it is cleaned, so as to prevent dust from being absorbed and causing harm to human body, its high temperature and thermal radiation.

 

 

Injuries also need to wear protective clothing in order to ensure.

 

 

If the complex shape of gravity casting is similar to many other large-scale production methods, the tolerance can be better controlled when using die casting to produce complex shape products. Basically, it can be used without mechanical processing, or the amount of processing is very small, which is more suitable for mass production.

 

 

Dimensional accuracy stability of castings is very high, basically equivalent to 6-7 grades, or even up to 4 grades; it can be increased to 25-30% than the general sand casting, parts size stability, good interchangeability, size stability while maintaining a tight tolerance, especially heat resistance and durability is relatively good.
