In-house toolmaking

Even before the actual production, we are active in the factory’s own design and toolmaking. This saves time and effort, as does the subsequent post-processing by machining and thread rolling at TIGGES.

FAQ's

Hot forming is particularly suitable for highly stressable components (such as connecting rods, cylinders or gears) and materials, e.g. Inconel. During hot forming, only low forming forces are applied due to the heat input. Compared to cold forming, the formability is very high.

This production technique is opposed by a high energy input. It is necessary to weigh up the costs and benefits in order to obtain the best possible result from hot forming. 

In forming technology, we distinguish between cold, semi-hot and hot forming.

The addition of heat in the forging process enables the forming of high-strength materials - useful for highly stressable components. 

The temperature during forming is variable, depending on the type and material. Each material harbors a different microstructure and requires a specific temperature window.

In cold forming, the material consumption due to lubrication or the tool load is significantly lower.

When steel materials are used, the disadvantage is that scale formation as well as component distortion can occur due to the strong temperature influences.

Compared to cold forming, the surface quality of the hot-formed part is significantly poorer and usually requires post-processing steps.

Cold forming and hot forming differ in the following respects:

Hot forming

  • Forming above the recrystallization temperature
  • Large changes in shape possible
  • Low forming forces
  • Dimensional tolerances and surface quality worse
  • than with cold forming
  • Scaled surface
  • Hardening is constantly degraded again

Cold forming

  • Forming below recrystallization temperature
  • Smaller deformation possible
  • Higher forces with comparable degree of forming
  • Narrow dimensional tolerances possible
  • No scaling of the surface
  • Hardening can be reduced after forming by recrystallization annealing
