CHW Forge has deployed a world class production infrastructure

3800 MT Automatic Hydraulic Open Die Forging Press

This open die forging press is a very stiff and rugged under the floor press, also known as pull down press having an extremely low center of gravity. The pull down concept also provides a clean forging area with excellent accessibility. The press has extraordinary dynamics and a speed of 215mm/s and has 110 strokes per minute. A rail bound Manipulator on one side and a mobile Manipulator on the other side of the press can be remotely controlled simultaneously by the press operator from the control desk.

This unique press can be used for various forging processes:

  • High speed open die forging
  • Forging of large rings and sleeves through saddling process
  • Direct upsetting
  • Sequential upsetting on a rotating table
  • Straightening of shafts
  • Punching and piercing of forged billets

Manipulators

To support the ODF press, we have the latest manipulators to facilitate the manufacture of forged products. These
manipulators are supplied by Dango & Dienenthal, Germany. In the past manipulators were normally built with heavy
structure to make them rigid. The high weight of the machine made the manipulator sluggish and slow. The new compact design ensures that the manipulator is strong and rigid and has fast movements without losing rigidity.

30 MT Rail Bound Forging Manipulator

Our open die forge shop is equipped with Rail bound forging manipulator of 30 MT carrying capacity and maximum tongs moment of 60 Ton-Mtr.

WORLD CLASS HEATING FURNACES

CHW Forge continuously strive to install latest technology to reduce energy costs and carbon emissions. Our forge shop is equipped with modern gas fired and electric operated furnaces. The furnaces can be operated up to 1270 degree centigrade.

40 MT Car bottom gas fired reheating furnace with regenerative flat flame burners

This furnace is equipped in lightweight design for a flexible operation and with air-preheating for an economic operation. An essential advantage of this furnace, especially when using high-quality material, is that no overheating at the surfaces occurs and therefore an optimum homogenous heating can be guaranteed.

30 MT Chamber gas fired reheating furnace with regenerative flat flame burners

The furnace is fired by 4 regenerative burners which are arranged above the material on the roof of the furnace. Due to the number of burners and their arrangement, an optimum distribution of the burner performance over the entire furnace area is assured. Each burner is provided with a regenerator for pre-heating of the combustion air up to approx. 1100 degree centigrade. The burner is controlled in
AM-REGTAKT mode which ensures the maximum heating before the burner starts.

5 MT Car Bottom Electrically Heated Furnace

The furnace is provided with Silicon Carbide type heating elements located on all the 6 sides of the furnace including the floor and the door. This is a car bottom furnace which can be driven out with very high speed thereby saving the heat energy. This furnace is capable of meeting heat uniformity even at a temperature of 1250 degree centigrade. This
furnace is suitable for heating of exotic materials, super alloys, titanium etc.

10 MT Chamber Electrically Heated Furnace

This is an electrically heated fixed hearth type furnace. It is suitable for heating aluminium alloys. The emperature
uniformity is maintained with the help of 2 centrifugal flow type re-circulation fan located at the roof of the furnace for efficient circulation of hot air inside the heating chamber.
