The fundamentals of forming technology
What is meant by forming technology?
Forming technology covers manufacturing processes in which a workpiece is brought into a new geometry by plastic deformation, without material being removed. This allows efficient use of the material while preserving its mechanical properties.
Which materials are used in forming technology?
In forming technology, metallic materials such as steel, aluminium and copper are used predominantly. Modern developments have also enabled the processing of new materials, including high-strength steels and titanium alloys.
How does process design in forming technology work?
Process design is based on a detailed analysis of the requirements of the component, such as geometry, loading and material properties. Simulation methods play an important role, in order to examine formability and optimise the process.
Types of forming processes
What are the most important forming processes?
According to DIN 8582, forming technology is divided into six main groups:
- Compressive forming: processes such as rolling, pressing and drop forging.
- Tensile compressive forming: examples are deep drawing and spinning.
- Tensile forming: includes stretch forming and stretch drawing.
- Bending: used for the manufacture of tubes and enclosures.
- Shear forming: processes such as torsion.
- Open-die forging: enables the manufacture of individual geometries.
How do the forming processes differ?
The processes differ in the type of force application and in the target geometry. Drop forging is used for complex components in large series, whereas open-die forging is ideal for individual pieces or small series.
What are the advantages of forming processes?
- Material efficiency: no material removal, therefore hardly any offcut.
- High strength: deformation densifies the material, which increases strength.
- Versatile geometries: complex shapes can be produced efficiently.
Fields of application and use of forming technology
Which industries benefit from forming technology?
Forming technology is used in many industries, including:
- Automotive industry: manufacture of body and engine parts.
- Aerospace: production of lightweight, high-strength structures.
- Medical technology: manufacture of precise components, e.g. for implants.
- Construction: production of tubes and load-bearing structures.
How are formed components used in industry?
Components such as enclosures, tubes and profiles are used in machines, vehicles and buildings. A further example are precise sheet metal parts for electric motors and turbines, which are manufactured by sheet forming.
Which new materials are used in forming technology?
Besides traditional materials, high-strength steels, aluminium alloys and composite materials are increasingly used, meeting the demand for lighter and stronger components.
How is optimisation of forming processes carried out?
Which factors influence the optimisation of forming processes?
- Material selection: the properties of the material determine formability.
- Process parameters: pressure, temperature and speed must be set precisely.
- Tool design: high-quality tools minimise deviations and extend service life.
How is the design of forming processes carried out?
The design of forming processes is performed using simulation software that visualises the deformation of the workpiece in individual stages. This sequence of stages allows precise planning and error avoidance.
What are typical challenges in process optimisation?
- Material deflection: can lead to undesired geometric deviations.
- Tool wear: reduces process stability and requires regular maintenance.
- High complexity: requires intensive training and experience with forming machines.
What are the advantages of forming technology?
How does forming technology contribute to weight reduction?
By using high-strength materials and precise forming processes, thin-walled components can be produced which significantly reduce overall weight while maintaining stability.
What are the economic benefits of forming processes?
- Cost savings: efficient use of material and high production speed lower manufacturing costs.
- Scalability: forming processes are suitable for both small series and mass production.
How does forming technology improve manufacturing efficiency?
Modern forming technology combines flexibility and precision, enabling the manufacture of complex geometries in short time.
Which machines and tools are used in forming technology?
What are the common forming machines?
- Presses: for bulk forming and sheet metal parts.
- Rolling mills: for continuous production of profiles.
- Open-die forging machines: for individual geometries and small series.
Which tools are required for forming?
The tools include dies, punches and forging dies that are specifically adapted to the requirements of the respective component.
How is tool selection in forming technology carried out?
Tool selection is based on:
- Material of the workpiece.
- Complexity of the geometry.
- Surface and precision requirements.
