Molding is one of the important metals that form the process in the manufacture of components for various applications in the industry. Molding of any size and shape can be done accurately. Automation in this field helps improve the casting environment and the precision of the castings. The efficiency of the molding is affected by several parameters such as permeability, collapse, tackiness, etc. Therefore, it is a necessity to avoid defects in the casting. Defects occur in sand smelters after a major problem in smelting. Due to defects, more than 10% of castings are rejected. Even when skilled labour is employed for the tamping operation, the packing of the molding sand will not be uniform through the molding box. So we have selected the idea of making "PNEUMATIC RAMMER". This rammer is pneumatically operated. By using this sand molding rammer will be evenly packed throughout the box.
The pneumatic tamper is used to push the sand evenly around the pattern. It can be used even in small scale industries. An air compressor is required to operate this rammer. A stop that is attached to the bottom of the piston rod functions the funnel. The pressure developed inside the cylinder alternates the piston and, therefore, the end. This rammer is driven by an operator simply by moving it on the molding sand. The end pushes the sand in moved places and the sand is evenly pushed. This rammer reduces tamping time and labour. Due to this the cost is reduced considerably. So this machine finds application in foundries.

No separate ability is required to operate this rammer. The operation is fast and therefore a time saver. The operation is easy and consumes less cost. Due to the above reasons, it finds its extensive application in the manufacturing industries.
