Manufacturing Process Features

  • An integrated production system that encompasses from in-factory pattern shop to annealing furnaces and various testing equipment ensures stable quality management and delivery in shortest period possible.
  • Production of high quality products based on excellent technical capabilities of long-serving master technicians.
  • Various know-how on casting process that has accumulated over many years ever since Hwacheon introduced the Furan casting process for the first time in Korea.
  • Continuous drive towards environment-friendly process improvements to prevent pollution and build clean and refreshing work environment.
  • Specialized molten metal treatment technique (inoculation) and management of not only C, Si, and Mn, the core elements of cast iron, but also the trace elements endow material properties optimized for machining and utilization characteristics.
  • Highly reliable, internally and externally sound products are supplied through molten metal filtering using ceramic filters, defect-free casting designs, and ultrasonic testing of the inside of castings.
  • Universal material tester, hardness tester, sand strength tester, C&S component analyzer, spectroscopic component analyzer, ultrasonic tester, 3D layout machine, metal microscope & image analysis system, stereoscopic microscope, portable hardness tester, others
    Others: Pattern shop, finishing facilities
