Increase productivity is the aim of any international company. Focus on achieve their goals many of them invest their resources to survive in a global competition. Under this paradigm, the present chapter exposes the problem that one automotive organization had with a CNC laser cutting machine used in the production process of airbags. The cutting process was identified as a botleneck slowing down the rest of the production process causing problems. TO overcome this problems a continuous improvement team was assembled. The problem was model as a travelling salesman problem and improvement was achieve. The economic benefits of the solution are presented to show the effectiveness of the proposed methodology.

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.
