The strength and durability of hot forged parts makes them ideal for more rugged applications, some of which include:

  • Automotive manufacturing
  • Agriculture
  • Tools and hardware
  • Aerospace
  • Construction equipment

What is  hot forging?

Hot forging is a metalworking process in which metals are plastically deformed above their recrystallization temperature, which allows the material to retain its deformed shape as it cools. Sun Fast provides an unprecedented approach to offshore hot forging and impression forging. Our experts deliver proven industrial isothermal forging outsourcing services for the steel and metal industries.

Advantages of  hot forging:

  • Good ductility
  • Excellent surface quality
  • Increased flexibility
  • Good for custom parts

What are the differences between hot and  cold forging?

The cold forging manufacturing process increases the strength of a metal through strain hardening at a room temperature. On the contrary the hot forging manufacturing process keeps materials from strain hardening at high temperature, which results in optimum yield strength, low hardness and high ductility.

Finally, a manufacturer would choose one process over the other because of economic and not quality reasons. The decision is based on the required functions of the desired component, the industry and if it’s a mass production or a low volume of customized parts.

VMT provides coldwarm and hot forging or combination of different processes to address various customer demands, both performed in excellent conditions with state-of-the-art machinery for perfect results. We work close with our customers to understand their specific needs and find the best possible solution.

The Hot Forging Manufacturing Process

The hot forging manufacturing process is performed at extreme high temperature (up to 1150 °C for steel, 360 to 520 °C for al-alloys, 700 to 800 °C for cu-alloys). This temperature is necessary in order to avoid strain hardening of the metal during deformation. Stamping is the most widespread hot forging manufacturing process, where the material is squeezed in a press, between a tool and a die surface.

Cost Efficiency in Hot Forging

The minimization of energy costs during hot forging is an ongoing concern of every manufacturer. Those can be optimized when using an inductor and a billet with matching diameters and installing a flexible multi-stage heating system.

The automatization of all involved forging presses is essential for the cost efficiency of the hot forging manufacturing process, especially for industries that require high volume production runs as the automotive one.

All applied tools should be optimized for the following innovative technologies:

Metallurgy: consolidated vacuum, powder metallurgy
Heat treatment
Surface treatment: nitriding, carburizing and duplex treatment

Hot Forging Materials

Hot forging can be used to fabricate a broad spectrum of parts, and can be performed with most metal materials, including:

  • Carbon steel
  • Aluminum
  • Titanium
  • Copper
  • Nickel alloys

Shaping and Tolerances:

  • design basis between ISO 10243 and ISO 10254
  • tolerance class forging grade F (IT 14)
  • tolerance class forging grade E (IT 16)
  • allowance of between 1,5 and 2 mm per surface
  • allowance of <1mm for near-net-shape surfaces
  • NF EN 10243 -1 with accuracy levels: quality F or E
