Pengembangan Produk Spring Steel Menggunakan Kerangka Kerja Quality Function Deployment (QFD)

Abstract

Market demand for spring steel-as a railroad anchor–is on high level but the domestic producer in Indonesia is still in the lack of product existance to fullfill its requirements. So that, the material sourcescomes from the abroad country supplier. To fullfill the customer demand for spring steels, manufactures needs product development to create spring steel refers to specifications based on customer needs and tehnical standards. This research objective is how to propose product development for spring steel from material scrap of HRC both of SPHC type and SS400 type. The approach method using Quality Function Deployment (QFD) in which consist of seven primary steps. Data collecting with survey, literature study about international standard requirements and focused group discussion with R&D dan project engineer from both of the customer and producer. The result is QFD framework can be applied for developing spring steel products as follow the customer needs.Keywords: Product development, Spring steel, Quality function deployment.
