Press Brake

For sheet metal bending, the press brake is a necessary machine. We have NC type and CNC type press brakes. At the same time, we can customize the punches and dies according to your practical use in sheet metal fabrication.

Shearing Machine

For the straight cutting of steel plate, hydraulic shearing machine is a good choice. It not only has high cutting efficiency, but also requires less investment. We have both swing beam shears and guillotine shears for your selection.

Laser Cutting Machine

In the current metal plate and pipe cutting, laser cutting machine is undoubtedly the best choice. It can not only cut various shapes, but also has small cutting gap, high precision and high cutting efficiency. Today, it is very cost-effective.

  25. Tooth return: refers to the process of repairing the second screw tooth of the workpiece with teeth in advance.
  26. Sticking: refers to the process of protecting the workpiece surface with a film that can protect the workpiece surface.
  27. Tearing: refers to the cleaning process of the protective film on the surface of the workpiece.
  28. Shape correction: refers to the process of adjusting the formed workpiece.
  29. Heat shrinkage: refers to the process of using heating equipment (hot air gun, oven) to compress the plastic covering the workpiece.
  30. Labeling: refers to the process of labeling to the designated position of the workpiece.
  31. Wire drawing: refers to the process of using wire drawing machine and abrasive belt to treat the surface of workpiece.
  32. Polishing: refers to the process of polishing the workpiece surface with polishing equipment.
  33. Heat treatment: refers to the process of special treatment to improve the hardness of the workpiece.
  34. Deburring: refers to the process of removing the rough edges of the workpiece with tools such as grinder and file to make the machining place of the workpiece smooth and flat.
  35. Argon arc welding: refers to the process that the workpiece is connected with the workpiece and welded at the edge or joint of the workpiece by argon arc welding machine. It is divided into intermittent welding and full welding, which shall be clearly marked on the drawing.
  36. Touch welding: also known as “spot welding”, it refers to the process of face-to-face welding and connection of workpieces by touch welding machine.
  37. Planting welding: refers to the process of firmly welding the planting welding screw on the workpiece with a planting welding gun.
  38. Welding and grinding: it mainly refers to the process of making the welding scar of the workpiece smooth and flat by using grinding machine, file and other tools.
  39. Pretreatment: refers to the process of removing oil and rust on the workpiece with electrolytic solution, adding film coating (such as phosphating film) on the workpiece surface and cleaning it before painting or powder spraying.
  40. Dust scraping: refers to the process of using atomic ash to make up for defects on the workpiece surface, such as welding gaps or pits.
  41. Dust scraping and polishing: it mainly refers to the process of polishing the surface of the workpiece after dust scraping with a flat grinder or abrasive cloth.
  42. Oil spraying: refers to the process of spraying paint evenly on the surface of the workpiece with a special spray gun.
  43. Powder spraying: refers to the process of evenly spraying powder on the workpiece surface with a spray gun.
