The goal of this study is to develop a forming process for producing LH and RH parts simultaneously in L, R progressive dies by inserting two coils. The development and application of PLC synchronous control technology between coil feeder and press of two-row progressive-die equipment could meet the requirements of each forming process. As a result, productivity innovation of molding method and composite forming technology has made it possible to improve the productivity of LH and RH parts of 590㎫ high-strength materials. To develop a forming process that can be applied to productivity innovation, a two-row coil input progressive-die technology was developed compared to a robot line, and a material transfer guide and actuator of the mold according to the input of two-row materials was applied. In order to develop a heterogeneous composite forming process for simultaneous production of LH and RH parts, the problem of coil feeder facility for two-row coil transfer was solved and the Roll Guide of Uncolier was improved. In addition, the installed screw and guide enable precise straightness control of the coil during leveling, thereby eliminating the quality problems and improving productivity of LH and RH parts. The composite forming process of two-row materials input with high technical difficulty enables centralized production through reduction of facility investment cost and productivity innovation. With facility investment of ₩400 million for 500ton feeder line compared to facility investment of ₩1 billion for robot line, facility reduction cost was reduced by 60%. With the development of the two-row coil input forming process, the production volume per hour was increased from 500 to 1,894. In addition, the improved durability of manufactured parts improved the defect rate from 3% to 0.7%. And it is expected to increase sales of ₩271,655 thousand and reduce costs by ₩68,113 thousand per year.
