Never doing anything by chance, defining exact planning processes, providing precise engineering solutions and simulations as well as performing a high-end production with best materials: these are the cornerstones of our activities in the cold forming sector. Trust in us and give us the opportunity to analyze if a switch from your formerly turned to cold formed or combined parts might be possible.
up to 6 stage presses
short throughput times
The challenge in cold forming is to manufacture the end product directly. This enables us to keep post-processing costs to a minimum and to produce more economically. Our experience since 1925 enables us to manufacture the most complex geometries within narrow tolerance ranges in a process-stable manner.

We are processing all materials like steel, stainless steel, aluminium alloys, high-temperature resisting steels, titanium etc. on our efficient and modern machines of up to 6 forming stages. Standard or special materials – we manufacture according to your drawing.
The more complex the component, the more often post-processing steps are necessary. We perform a variety of different finshes.
Cold massive forming is versatile and provides ideal solutions for a wide range of joining requirements.

As also engineering, tool construction, wire drawing and others are performed in-house, we have the capability and flexibility to produce minimum quantities, like samples and prototypes, with a high profitability.
Cold forming is a high-speed forming process in which materials are plastically deformed. The compressive stress generated in the process fundamentally changes the material properties, but differs from material to material.
The manufacturing process used in the production of fasteners involves various methods of material processing: cold forming, thread rolling, and upsetting and extrusion processes.
The metal supplied is first shortened to the correct length and then formed in a coordinated manner by several punches and dies to gradually produce the final product. At TIGGES, this multi-stage pressing takes place in up to 6 stages.
In the field of cold forming, a distinction is made between cold drawing, cold forging, cold upsetting and cold extrusion.
At the beginning of the production of drawing parts, we ask ourselves which machining process is gentle on the material and economically efficient for the desired element. The strengths of cold forming lie in precise and accurately fitting surface structures. This makes it particularly suitable for high-quality built-in systems with tight dimensional tolerances. At the same time, this type of production offers cost advantages, since comparatively little energy is required with only a small amount of heat input (through preheating). Cold-formed parts can be produced more quickly thanks to shorter throughput times. Strength increases with the degree of forming.
The material also plays an important role. The higher the basic strength of the material, the stronger the forming forces, so hot forming may be more suitable.
Advantages at a glance:
During the forming process, the metal is plastically deformed (well below the recrystallization temperature) and subsequently retains the new shape structure. To avoid cracks and defects in the material during the structural change, it is not loaded beyond the material-specific tensile strength. The load limit varies depending on the material.
As a rule, all non-brittle metals as well as alloys are suitable for cold forming. The recrystallization temperature varies depending on the material, so that preheating must be used in some cases.
Hot forming differs from cold forming in that temperatures above the recrystallization temperature are used in these forming techniques.
While cold forming increases the strength (with a simultaneous reduction in ductility, elongation at fracture), hot forming causes only a slight change in strength and ductility on the formed component.
Due to the heat applied, the material can be formed much more easily, which means that only low forming forces are required in comparison to hot forming.
The complexity of the machines and systems in which our products are used is increasing. Components are being tailored to individual application areas and space conditions.
At the same time, the basic strength and variety of materials are increasing, which often pushes the technology to its limits. The forming of copper, for example, is not successful for everyone, as the material is very soft and thus only capable of bearing low loads.
It should be noted that cold forming also changes other material parameters and dimensions. For example, a higher strength after cold forming is accompanied by a reduction in ductility.
With our machinery, we at TIGGES are already prepared today for the challenges of tomorrow. We draw on decades of experience in the field of cold forming and know exactly how to implement your project intelligently.
