To handle the removal of sand from castings, metal casting machinery utilizes multiple methods. One commonly employed technique is known as shakeout, which involves shaking off the sand from the castings using either a vibrating table or a conveyor belt. Through the vibrations, the sand particles become loose and separate from the castings.
Another approach is called blasting, where either high-pressure air or abrasive materials are utilized to eliminate the sand. This method is particularly effective for intricate areas or parts of the casting that are difficult to reach.
There are cases where the castings undergo a process called shot blasting. In this process, small metal pellets are forcefully blasted at high speeds onto the castings. This not only removes the sand but also smoothens out any rough surfaces or imperfections on the castings.
Once the sand is removed, the castings may undergo a cleaning process to completely eliminate any remaining sand particles. This can involve techniques such as water or chemical baths, brushing, or tumbling.
In conclusion, metal casting machinery employs various techniques to handle the removal of sand from castings, ensuring that the final product is devoid of sand particles, smooth, and ready for further processing or use.
Metal casting machinery uses several methods to handle the removal of sand from castings.

Overall, metal casting machinery employs various techniques to handle the removal of sand from castings, ensuring that the final product is clean, smooth, and ready for further processing or use.
Metal casting machinery typically handles the removal of sand from castings through a process called shakeout. Shakeout involves vibrating or shaking the castings to dislodge and remove the sand from the surface. This is usually done in a separate vibrating chamber or by using specialized equipment such as shakeout tables or shakeout drums. Once the sand is loosened, it is collected and recycled for future use in the casting process.
