An engineered product is a collection of materials in the shapes of components and weld, solder, or adhesive joints. In fact, up to 70% of the cost to make a product is due to its materials. Therefore, it makes sense that getting the materials right will have a big impact on a product’s success. However, many organizations have difficulties getting the materials right, and they end up facing common problems such as:
During product development of a power tool, the material to use for a drive shaft was being considered. Based on the requirements for the drive shaft an aluminum alloy was identified as a potential candidate. Evaluations were performed to to determine whether the alloy was suitable. Also supplier evaluations were conducted to identify a capable supplier of drive shafts once the product went into production. This case study discusses the evaluations and their results.
