A simple pressing method for a stainless pipe to obtain an accurate screw thread without decrease of thickness has been ascertained. Recently, manufacturing technologies to lighten weight of car components have been highlighted due to reduce CO_2 emissions. In addition, the rapid increase in oil prices accceralate the necesity in manufacturing technologies to lighten products weight as well as to reduce materials in a product. This paper is concerned with the development of a pressing technology that cope with forming of relatively high strength stainless pipes with a screw thread on the surface of pipes. A simple manufacturing process in order to obtain an accurate screw thread on the stainless pipe was tested. A 3-D digitizing machine performed measurements of formed manufactures pipes. The decrease of pipe thickness was examined by measurement by a 3-D coordinate measuring machine. It is found that the proposed manufacturing method was effective to improve decrease of pipe thickness comparing to roll forming method.
