The foundry industry is one of the major industries where castings are produced. 70% of components of any automobile are produced with the casting process. To produce such intricate shapes hollow components cores are required which are produced in the core shop. Cores are produced with different processes. In the manual core-making (MCM) process cores are produced manually and have ergonomic issues along with other problems that are; core rejection is more, manpower requirement is more, less productivity, and higher cost.
In the four stations, the sub-stations are:
Investment, preheating, after heating, and ejection. Only one operator is required to operate the machine. The bucket elevator is installed on one side of the machine in which the sand is elevated to the top hopper for sieving. Below the top seiver hopper is mounted, with a pneumatically operated butterfly valve.
Core-making is an important branch in any foundry and the choice of core-making depends on various factors. To name them depends on the type of metal to be cast, depending on the size of the casting, choice based on the complexity involved in a casting process, depending on the requirement of quality in the final product, depends on the equipment used for production, and the energy source.
It gives foundries a capability that no other metalworking process offers: the ability to form external and internal contours, shapes, cavities, and passageways in one operation.
Foundries have always been interested in improving productivity and profitability. But, over the past few years of competitive pressure and general industrial conditions have reinforced metal casters’ resolve to refine current processes and to develop new technologies that improve productivity and reduce costs.
