  • Wood pattern factory Our on-site pattern-making factory with model machining equipment can handle patterns and resins up to a size of 1000x1000.
  • Alkaline Phenolic Molding factory This is a molding facility that solidifies sand by kneading an alkaline resin and hardener into artificial sand.
    Furan molding is also operated simultaneously, and it can handle various product shapes. Sand used is recycled using a sand reclamation system
  • High frequency induction furnace This equipment utilizes electromagnetic induction to efficiently and rapidly dissolve metals.
    It uses electric heating to dissolve, resulting in reduced CO2 emissions and environmental considerations.
  • Optical emission spectrometer This is an instrument used to analyze the chemical composition of products.
    By irradiating metals with light and measuring the wavelength and emission intensity of the element, the type and content of the element can be determined.
    It is also capable of analyzing special elements such as tungsten (W) and cobalt (Co).
