(A) high-speed forging hammer
    Bearing formation is the use of high-speed hammer 14MPa high-pressure gas sudden expansion in a short time, high-speed movement of the piston produces kinetic energy, and promote the hammer and frame systems for high-speed relative motion vacant blow to metal blank formed under high-speed impact processes. Suitable for high speed forging hammer forging of complex shape, thin-walled high-gluten precision forgings, such as blades, housings, fittings, gears and other forgings. Hammer can be forged in high-speed, high strength, low ductility bearing material. The bearing material can be forged aluminum, magnesium, copper, titanium, heat-resistant steel, tool steel. High-speed hammer forming the main features: process performance; forging good quality; forgings and high precision; material utilization; equipment is light, less investment; forging heating conditions demanding.
 (B) Explosive Forming
    Explosive forming is the use of explosive chemical methods to make metal material deformation. Explosion produced a large number of high-temperature high-pressure gas, so that the surrounding medium (water, sand, etc.) to dramatically increase the pressure and passes radially, the blank shape. This molding method, high speed, low investment, simple technology and equipment suitable for many varieties of small batch production, especially for some of the difficult process of metal materials, such as titanium, stainless steel Forming great.
 (C) forming the discharge
    Discharge shaped blank deformation mechanism and explosively formed basically the same. It is produced by the discharge circuit in a strong surge current, the electrode near the water vaporization and expansion, to produce a strong impact the blank shape. Compared with explosive forming, shaping the energy discharge control and adjustment simple forming process stability, safety, low noise, and high productivity. However, by forming discharge device capacity limitation, suitable for bulky shape.
 (D) electromagnetic forming
    The use of electromagnetic forming the electromagnetic force of the compression molding. The coil forming the pulse current for a very short time, the rapid growth and decay, and in the space surrounding the magnetic field to form a strong change. Forming the blank is placed within the coil, the change in the magnetic field, the induced current generated in the blank, the blank is formed within the magnetic field and the induced current magnetic coils forming the result of interaction, the blank of the electromagnetic force of the plastic deformation. This molding method of the bearing material should be used with good conductive properties of copper, aluminum, and steel. For a poor conductivity of the material processed, is placed in the rough surface of the drive plates made of thin aluminum, for promoting the blank shape. Electromagnetic forming water and oil do not need to like the media, tools, and almost does not consume, the device clean, high productivity, product quality and stability; However, due to the device capacity limitation applies only to small thickness of the bearing machining small parts, sheet or pipe.
