Advantages

  1. High-purity graphite ring has a smooth glazed surface, high geometric processing accuracy and low maintenance cost.
  2. No delamination and peeling phenomenon. It can effectively reduce the pollution of aluminum liquid, and achieve pollution-free precision aluminum casting.
  3. Erosion resistance, good thermal shock resistance, strong corrosion-resistance to molten metal.
  4. The life is long for normal 800-1200 casting times, graphite ring can achieve energy saving and consumption reduction.
