Various methods are utilized by metal casting machinery to handle the removal of excess sand from the castings. One commonly used method is shakeout, which involves shaking or vibrating the castings to dislodge the sand. This can be accomplished using a vibrating table or a mechanical shaker. The shaking motion aids in loosening and breaking up the sand, enabling it to separate from the castings.
Another method employed is sand blasting or shot blasting. During this process, the castings are subjected to a high-pressure stream of abrasive material, such as sand or steel shot. This abrasive material forcefully blasts off the excess sand from the surface of the castings. Sand blasting is particularly effective for eliminating stubborn or hard-to-reach sand particles.
In addition, some metal casting machinery may employ gravity separation or gravity settling. In this method, the castings are placed in a container or tank filled with water. The heavier castings sink to the bottom, while the lighter sand particles float to the top. The excess sand can then be skimmed off or drained from the tank, leaving behind clean castings.
Moreover, advanced metal casting machinery may utilize automated systems, including robotic arms or mechanical conveyors, to handle the removal of excess sand. These systems can be programmed to carefully manipulate and transport the castings while simultaneously eliminating the sand using any of the aforementioned methods.
Overall, metal casting machinery combines shaking, blasting, gravity separation, and automation to effectively handle the removal of excess sand from the castings. These processes guarantee that the castings are left clean and free from any remaining sand particles, resulting in finished products of high quality.
Metal casting machinery uses various methods to handle the removal of excess sand from the castings. One common method is called shakeout, where the castings are shaken or vibrated to dislodge the sand. This is usually done using a vibrating table or a mechanical shaker. The shaking action helps to loosen and break up the sand, allowing it to separate from the castings.

Metal casting machinery handles the removal of excess sand from castings through a process called shakeout. After the metal has solidified, the castings are shaken or vibrated vigorously to break apart the sand mold and separate it from the metal. This process helps to remove the excess sand and prepare the castings for further processing or finishing.
