Prior Technology

  • Prior technology conducts our own R&D and cooperative researches of Industry-University relation in order to solve the difficulties of the industrial field and the technical needs on automobile parts. In order to produce light but strong body parts, we are accelerating the development of the entire process on development of ultra-high-strength steel parts with GIGA grade tensile strength, development of new method applying new material as CFRP (Carbon Fiber Reinforced Plastics) and development of materials, molding, bonding parts such as as laser process technology with fast production speed. Among them, the forming technology of super high tensile steel plate with 150K grade is the molding technology developed as Korea-first, which has become an opportunity to make the shaping material technology one step further.
