The purpose of this study is to improve a process of the automatic manufacturing system for producing a phosphor bronze wire developed the previous study. For this purpose, the authors have improved the manufacturing process, such as wire tension control, discoloration, winding and the control appears as a problem when the automatic manufacturing system applied to the field. Also, performance tests for the developed system such as the straightness, tensile strength, hardness, diameter deviation, discoloration have been performed. As a result, we could product the 0.35mm of phosphor bronze wire with continuous processes. The performance of the prototype system satisfies all the objects of this study.

The purpose of this study is to develop the automatic manufacturing system for producing a phosphor bronze wire. Automatic continuous manufacturing system is necessary to raise the productivity and strengthen the competitiveness in the phosphor bronze wire manufacturing. For this purpose, the authors carrying out the design and production of devices such as raw material supply, drawing, heat treatment, winding and main control system, etc. As a result, we could product the 0.35mm of phosphor bronze wire with continuous processes.
