HOT FORGING


Chartway (Asia) Manufacturing Capacity

Established in January 2002, Chartway (Asia) has grown to provide leading OEM’s throughout Europe with the highest standards in Hot Forged and Precision Machined Components.

Hot Forging

Our Hot Forging workshop is equipped with 32 Sets of Hot Forging Machines ranging from 25 tonnes to 400 tonnes, producing forged blanks up to a maximum of 10 kilos. This modern forging process guarantees a very precise, high integrity forging with excellent strength.

Using our CAD system and technical expertise we can ensure the most cost effective design of the molding die so reducing the material & machining cost. This means we are able to provide our clients high integrity components at a very competitive price. The cost of the die is not charged until samples have been supplied and complete customer satisfaction has been achieved.

Hot Forging Process

Hot Forging or Hot Stamping is a production process which “hammers” metal between two dies to form the desired shape. Half of the die is attached to the “hammer” (upper section) and the lower half of the die is attached to the “anvil” (lower section). A metal “blank” is placed in the lower half of the die and then “struck” with the upper die. The force of the strike forces the metal to flow in all directions, filling the die cavity and giving the parts a very strong grain structure. Excess metal is squeezed out between the die faces, and is called flash or flashing. After the forging operation, the flash is cut off in another press with a trimming die.

Secondary Machining

Following the Hot Forging process the parts are allowed to cool, the ‘flash’ is then removed and they are transferred to our machine shop for finishing to the customers drawing.

COLD FORGING (COLD HEADING)


Cold forming is the process of forging metals at near room temperatures.

In cold forming metal is formed at high speed and high pressure into tool steel or carbide dies. The cold working of the metal increases the hardness, yield, and tensile strengths.

Cold forging has many benefits and in recent years tehcnology has improved significantly. The main benefits of cold forging are...

  • Design Versatility
  • High Production Rates and Repeatability
  • Almost 100% Material Utilisation (No Waste)
  • High Product Strength
  • Almost No Secondary Machining Required

All of the above makes Cold Forging an extremelly cost competitive option.
