What is the classification system of manufacturing processes according to DIN 8580?
Definition and purpose of DIN 8580
DIN 8580 is a standard for the systematic classification of manufacturing processes in production technology. It defines a structured classification system that categorises all common manufacturing processes into six main groups. The aim of the standard is to establish a uniform terminology and to facilitate communication between engineers, production technicians and companies.
The six main groups of manufacturing processes
- Primary forming: producing a solid body from shapeless material (for example casting, sintering)
- Forming: change of shape without loss of material (for example forging, rolling)
- Separating: processing through material removal (for example turning, milling)
- Joining: connecting workpieces (for example welding, soldering)
- Coating: applying a layer of material (for example painting, electroplating)
- Changing material properties: altering material properties (for example hardening, soft annealing)
Significance of Main Group 4: Joining
How is the main group of joining structured in DIN 8580?
Joining is one of the most important main groups of DIN 8580 and describes all processes in which two or more workpieces are permanently or detachably connected. In DIN 8580, joining is divided into several subgroups, including welding, soldering, gluing, screwing and riveting.
Important joining processes and their classification
The most important joining processes include welding (thermal connection), soldering (connection via filler material) and gluing (molecular connection). These processes play a central role in the automotive industry, aerospace and mechanical engineering.
Which updates have there been in DIN 8580 regarding the main group joining?
Latest changes and additions
In recent years, additive manufacturing processes (for example 3D printing) have been considered as a potential addition to the standard. DIN 8580 is reviewed regularly to ensure it reflects current technological developments.
Influence of new technologies on classification
With the introduction of laser welding and micro-bonding, the possibilities in the joining area have expanded. These technologies enable more precise connections and have led to the standard being revised and supplemented.
How does joining differ from other main groups of manufacturing processes?
Comparison with primary forming, forming and separating
In contrast to primary forming, where a workpiece is created from shapeless material, and forming, where the geometry of an existing workpiece is changed, joining aims to connect two or more existing components. In separating, on the other hand, material is removed to achieve a desired shape.
Special features of joining in the manufacturing process
Joining differs from the other main groups in that it creates a mechanical, thermal or chemical connection between components. It is often the last step in the manufacturing process and has a direct influence on the quality and longevity of the end product.
What role does the DIN Standards Committee for Technical Fundamentals play in DIN 8580?
Tasks and responsibilities of the committee
The Standards Committee for Technical Fundamentals (NATG) is responsible for maintaining and developing DIN 8580. It ensures that the standard reflects the latest scientific findings and industrial requirements.
Process of standard development and updating
The updating of DIN 8580 takes place in a multi-stage process involving experts from science and industry. New technologies and processes are evaluated and, if necessary, incorporated into the standard.
How is DIN 8580 applied in the practice of manufacturing technology?
Benefits for companies and engineers
DIN 8580 offers companies a clear structure for classifying their manufacturing processes. It helps engineers to select the right method for their applications and supports quality assurance and the development of more efficient production processes.
Challenges in implementing the standard
Despite its advantages, the application of DIN 8580 can present challenges in practice. Companies must ensure that their manufacturing processes are classified correctly while taking technological and economic factors into account.

GOBA Takeaway
DIN 8580 is a fundamental tool of manufacturing technology, enabling systematic classification of all manufacturing processes. With its six main groups, the standard provides a structured classification system that is particularly important for the main group of joining. Regular updating of the standard ensures that it reflects the latest technological developments. For engineers and production planners, DIN 8580 remains an indispensable reference work.
