Cold forging

Cold forging process

（1）According to the theory of metal plastic deformation, a certain pressure is applied to the metal blank at room temperature to make it produce plastic deformation in the mold cavity and form according to the specified shape and size.

（2）High quality metal materials with good "plastic deformation" must be selected, such as rivet steel, whose chemical composition and mechanical properties have strict standards.

（3）There are many models and series of cold heading bolt and nut forming machines. The equipment has reliable performance, high efficiency and stable product quality.

（4）The forming and upsetting force of the product is large, the configuration power is, and the equipment is invested at one time. Therefore, the production specification below M24 is the most economical.

（5）It has good surface quality and high dimensional accuracy. Because there is cold work hardening in the upsetting process, the deformation should not be too large. Reduce cracking.

Sheet metal part

Sheet metal parts are sheet metal parts, that is, parts that can be processed by stamping, bending, stretching and other means. 

Equipment：

Generally speaking, the basic equipment used for sheet metal includes shear machine, CNC punching machine / laser, plasma, water jet cutting machine / combinationmachine, bending machine and various auxiliary equipment, such as uncoiler, leveler, deburring machine, spot welder, etc

Generally, the three most important steps in a sheet metal factory are shearing, punching / cutting and folding. Modern sheet metal processes include filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, etc.
