Nowadays, the automotive industry is one of the most demanding and competitive sectors in the global market. This competitiveness leads to the suppliers to constantly look for the development and improvement of their production process without affecting the final quality of the product and not increasing the corresponding associated cost. One of the many ways factories/suppliers can become more competitive compared to others is by having shorter delivery times, but with that a short time cycle of production must be achieved.

摘要

Nowadays, the automotive industry is one of the most demanding and competitive sectors in the global market. This competitiveness leads to the suppliers to constantly look for the development and improvement of their production process without affecting the final quality of the product and not increasing the corresponding associated cost. One of the many ways factories/suppliers can become more competitive compared to others is by having shorter delivery times, but with that a short time cycle of production must be achieved. The work here presented shows the implementation of an auxiliary feeding system designed to not only reduce the cycle time associated with the production of Bowden cables, but also to reduce the excessive traction load made in the tube when its cable length, unwound from the storage coil, is too short. Taking into attention the improvement focusses of this work, the Design Science Methodology was chosen, helping in following the necessary steps to reach the ideal result. Regarding the solution developed and implemented, the excessive traction load in the inner tube was eliminated, thus ensuring the requested quality of the Bowden cable, and a cycle time reduction of 17.98% was also achieved, reducing the production costs and helping in becoming the product more competitive in the market.
