With a goal to achieve near-finish size of plastic products, Samjin predicts and prevents forging defects, which can occur inside products, at the same time as developing optimal designs through new forging material development and finite element analysis for forging process verification. Many parts that used to be manufactured through cutting process are now being produced economically and in uniform quality through a composite production process combining cold forging, hot forging, and press machining.
