Tongxin Free forging products

Tong Xin precision forging Co., Ltd. is a professional forging company with a history of more than 70 years，

The main products of our company are: forging series: shaft, gear, gear ring, module, wheel, roll, round, square, sleeve engineering machinery parts, mainly die forging, tire die forging, free forging and other forging process, can undertake all kinds of forging parts.

Metallurgy, forging and power generation equipment is the basis of the development of modern industry and national economy, is an important product of heavy machinery manufacturing industry, but also the main products that need large forgings. One of the keys to making these devices is the production of large forgings. Forgings required by thermal, hydraulic and atomic power generation equipment require high quality and can be used as representative products of large forgings. Attaching importance to and strengthening the production of large forgings, improving quality, reducing production cost and shortening production cycle are of great significance for promoting the production of heavy machinery products, developing industry and agriculture and consolidating.

Tong Xin precision forging Co., Ltd., our products are: forging series: shaft, gear, gear ring, module, wheel, roll, round, square, sleeve engineering machinery parts, mainly die forging, tire die forging, free forging forging process, can undertake a single 5KG to 20 tons of various forging parts.

Usually, the forgings produced by free forging hydraulic press with 10 MN and above are called large forgings, equivalent to shaft forgings with a single weight of more than 5T, cake forgings with a single weight of more than 2T.

The main varieties of large forgings include:

1) Forging of rolling machine, such as cold and hot rolls, etc.

2) Forging equipment forgings, such as columns and cylinder blocks of hydraulic press.

3) Thermal power forgings, such as generator rotor, retaining ring, turbine rotor, impeller, etc.

4) Water and electricity forgings, such as the main shaft of water turbine generator, mirror plate, etc.

5) station forgings, such as pressure shell, evaporator barrel, tube plate, etc.

6) Petrochemical pressure vessel forgings, such as cylinder, flange and sealing head of high pressure vessel.

7) Marine forgings, such as stern shaft, intermediate shaft and crankshaft of Marine engine, etc.

8) Cement equipment forgings, such as ring teeth, etc.

9) Forgings of mine lifting equipment, such as spindle, etc.

10) Inner and outer rings for oversized bearings.

11) Modules for die forging hammer and press.

12) Forgings, such as gun barrel, pressure shell of nuclear vessel of nuclear submarine, turbine disc of jet engine, etc.

13) Various axles of railway rolling stock.

14）Spindle for large AC and DC motors.
