IMPROVEMENT IN PRODUCTIVITY OF CASTINGS BY SWITCHING FROM GREEN SAND MOULD PROCESS TO SHELL MOULD PROCESS

The creation and application of technology to monitor and control the production and delivery of products and service in casting foundries has gained importance and are necessary to sustain in competitive market conditions. Setup of the industries as applied to casting foundries need timely setup and changes to cope up with the increasing demand from the customers as foundries have great demand for the products produced, in numerous fields. In this work various parameters of importance are improved by employing shell mould process for the production of the castings which were previously produced by green sand mould process. Parameters considered in this work are to achieve overall productivity of castings. In this regard delivery of castings, reducing rate of rejection, improving the yield, methods to improve quality etc, plays an important role. Accordingly work to achieve all these, without forgetting cost and economical considerations to get greater profit is done. Apart from these, to sustain in the market, customer is required to be satisfied with the product produced. In this regard work has been carried out which is towards getting more demand for the product. And also manual work is reduced by employing the machineries, which brings many changes in foundry and hence towards automation.
