Molding is one of the important metals forming process in manufacturing components for various applications in industry. It is important to make cast product precisely. Automation and sophisticated electronics in the ramming process helps to improve the foundry environment and accuracy of the cast parts. The reliability of the cast products depends on various parameters like permeability, compactness, adhesiveness, etc. Hence the process of ramming in molding plays a vital role in the process of casting. The defects that occur in the cast component lead to a great problem in foundry and all associated industries. Hence this ramming machine found large applications in the manufacturing industry. The machine is operating on electric drive motor. Even though skilled labor is employed for ramming operation, the packing of molding sand will not be even throughout the molding box. So we have selected the idea of fabricating “MOTOR OPERATED AUTOMATIC RAMMING MACHINE”. This machine is operating mechanically. By using this machine molding sand will be packed evenly throughout the box. The machine is operated by five electric motors that are electronically operated. The ramming tool rod work as a connecting rod hence the rotary motion of motor converted into reciprocating motion of ramming tool. There are four lead screws that convert the rotary motion of the motor into linear movement of ramming tool and impart movement to it so that ramming tool moves within the entire working space so that ramming will be uniform on the sand. Two lead screws used for imparting transverse motion to tool in the plane perpendicular to the tool while the remaining two are used for elevating the tool position in the plane of tool for further compaction of sand.
