Rancangan Perbaikan Produk Saklar Dengan Integrasi Metode Qfd Dan Dfma Di PT Xxx

The design phase plays an important role in the production process of the switch products, because the design is related to the manufacturing process, Assembly time and cost of production of the product. More easily assembled design will improve the efficiency of the use of time that leads to a decrease production costs. This research aimed to evaluate the design of existing products by using the concept of integration of QFD (Quality Function Deployment) and DFMA (Design for Manufacture and Assembly). DFMA is a method that emphasizes on the development of the design to its simplest form without losing the market desire and produk reasearch functionality, starts with identification at initial switch product design by using QFD method. Based on QFD method obtained two influential Assembly process attributes significantly to product assembly time. The calculation time is done by using method of stop watch time study know the Assembly time. Next repairing the design of a product with DFMA method to reduce assembly time and cost component of products. Improvement of the design is done by reducing or eliminating components that do not give the value added to the product such as fasteners. The results of this research show that the Assembly time reduced by 17,83%, the number of components was reduced to 11,43%, as well as the total cost of the Assembly reduced to 17,82%
