CAD Applied to the Design and Cost Reduction in the Use of Molds for DIE Casting Process

Abstract

During the last three decades the increase of utilities is the principal aim of the international companies, focus on this topic, many companies have been invested resources on investigation and innovation, develop new techniques and implementation of procedures standardized by the global competitors. According to the references mentioned before, a case of study is used to improve the productivity of a die casting process, the methodology used consists in the integration of a design technique and the methodology DMAIC. The results showed that the new design of the casting mold weight reduced by 18% percent the quantity of material requires for the original product, from an initial weight of 2.77 lb to 2.20 lb. Also, through the modification of gates and metal runners in the mold, a 60% reduction of material waste was achieved. With the new prototype, the scrap was reduced from 13.65% to a new 6.45% of the piece. This is a 54% reduction on the SCRAP. With the information above mentioned, it has been achieved a save of $2.23 USD per unit, a total of $25,958.00 USD by year.
