Please provide design data for special processing requirements


Hot steel billet automatic spraying mark machine (aluminum wire/copper wire)

  1.  Design and configurate corresponding spraying mark equipment according to site actual situations.
  2. The metal wire sprayed by electric arc is suitable for marking large cross sections, the spraying character is firmly.


Robot Plasma Marking System

  1.  Using the principle of high-energy beam scoring to realize automatic identification;
  2. Not limited by the temperature of the billet surface, not affected by the flatness of the infinite billet surface, the characters will never wear out;
  3. Non-contact identification method, low maintenance cost and no subsequent consumption cost.


Steel plate / steel coil / steel pipe mark spraying machine (painting).

  1. Use the spray gun to paint to form the handwriting on the surface of the billet, the handwriting is eye-catching;
  2.  Special nozzle design is not easy to plug, the amount of paint consumption is small;
  3.  Match with high temperature paint (200~ 1000°C), handwriting is not easy to fall off
