cold forging suppliers
In our modernized industrial manufacture, cold forging craft, as a precision forging forming technique, enjoys unparalleled virtues. What is more, the application of some advanced techniques, like numerical simulation technique and intelligent design technique, have powerfully facilitated the innovation and development of the cold forging craft.
Cold forging, generally speaking, is the joint name of cold die forging, cold extruding, cold heading and other plastic working arts. Usually, the cold forging is adopted by molding of materials under recrystallization temperature. Mostly, the materials with small resistance to deformation under indoor temperature are suitable for cold forging craft, such as aluminum, copper, a part of aluminum and copper alloy, low-carbon steel, medium carbon steel or structural alloy steel and so on.
As to the top virtues of cold forging technology, they can be concluded as several principal aspects. High material utilization, excellent mechanical property and outstanding productivity come very first. Take the aluminum forging process for example. There is almost no aluminum wastes at all after the contour machining. The adoption of cold forging by firearm manufacture can prove excellent mechanical property primely. The cold forging can improve the glossiness, dimensional accuracy and surface strength of bore. It also can prolong the working life of gun-barrel. In the meantime, the cold forging also can be used as the manufacturing method of final products, which leads to wide application range. Therefore, the cold forging craft is widely employed by such fields as means of conveyance, aviation and machine tool industry, because they ask for mass-production.
High-precision workpiece is another advantage. In forging factory, cold forging craft is the best precision shaping technique, especially after the participation of high technologies. Numerical simulation technique and intelligent design technique are widely chosen by many cold forging suppliers. The numerical simulation technique is used to verify the reasonability of craft and model design. For instance, the stress and strain in the metal flow, stress and lose efficacy of mold, and possible defect of forgings can be detected by the finite element numerical simulation technique intuitively. In the current, valid numerical simulation software can be chosen from Deform, Qform, Forge or Superform. Intelligent design, just as its name implies, is used to guide the cold forging forming craft as well as mold design, which saves the human resources, simplifies design procedure and enhances design efficiency. Above techniques are two most popular ones in cold forging area. As the computer technology develops by leaps and bounds, more advanced techniques will be born and applied to the cold forging craft in the near future.
