Forging the way
Diehl Metall Schmiedetechnik is an efficient development and production partner for sophisticated die-forgings.
In an integrated value-adding chain, we manufacture products of the highest precision and quality for various industries. In so doing, we combine our longstanding technological know-how with a high level of expertise in metals.
From swash plates to valves and ultra-modern smart meters – drop forgings from Diehl Metall Schmiedetechnik are the products of choice for applications in various industries.
- Automotive industry
- Domestic and building services (water supply, water treatment, measurement, heating techonolgy)
- Sanitary industry (lead-free, safe drinking water application, hygiene)
- Mechanical engineering (high-strength parts, wear-resistant)
- Electrical engineering (copper, brass and aluminum, broad material spectrum for electronic applications)
- Medical & laboratory technology (high-strength, safety-relevant aluminum parts)
Thanks to our longstanding experience, our broad service portfolio and our materials know-how, we are a specialist when it comes to offering sophisticated solutions.
Diehl Metall Schmiedetechnik produces die-forged parts in an integrated production process, which ranges from in-house prematerial production to the finish-machined product. In this way, we can ensure the quality of our forgings during all production stages.
Hot Forging – Performance at the highest level
Diehl Metall Schmiedetechnik produces die-forgings according to customer-specific quality criteria on fully automated forging lines. The production portfolio encompasses a multitude of copper alloys as well as aluminum, and a weight spectrum ranging from 10 g to 35 kg.
Besides series production of conventional die-forgings, we also specialize in sophisticated solutions, such as the manufacture of hollow forged parts (forgings with multi-directional cavities). This process is often used in the manufacture of water meter housings.
Machining – Precision and maximum quality at each stage
Diehl Metall Schmiedetechnik has a diverse range of machinery, including CNC machining centers with integrated measuring technology and inline quality control.
Besides raw forged parts, we also offer machining services for our products. In particular, we are able to machine special alloys, such as lead-free or low-lead materials, with high precision.
Die-forged parts – A deeper insight
Depending on the component, the forging process requires a billet which is optimally adapted to the die-forged part. The billet is initially heated to approx. 700°C before entering the forging press. Diehl Metall Schmiedetechnik uses both spindle as well as eccentric presses with a pressing force of up to 10,000 kN. Depending on the part geometry and size, forging is carried out in one or several stages. Even several components can be forged in one process step.
Right from the design phase, Diehl Metall Schmiedetechnik works together with its customers to develop specific solutions for achieving functionality, forgeability and quality at market-oriented production costs.
By means of an in-house Research & Development Center, complete with laboratory, we are able to provide our customers with full support as early as the product design phase and during the production process. This includes material selection suited to the application as well as optimized forging design.
Design & tool manufacture
A slice of independence with our in-house Tool Center
Our in-house Tool Center allows us to carry out all required steps at our company – from CAD design to the finished tool. In this way, we can produce new tools or make changes to existing ones at short notice. This leads to clear advantages for the customer:
- Changes to tools at short notice
- Off-tool parts as early as the prototype phase
- Increase in flexibility
- Optimization of tool life
Laboratory and material inspection
The laboratory – the heart of our quality assurance and material development
The function and service life of the forged parts are dependent on the material, the geometrical design and the optimum interplay of the individual part components. To attain the best possible solution for the particular requirements, we offer a broad spectrum of testing procedures:
- Hardness testing
- Micro hardness testing
- Quantitative microstructure analysis
- Tensile testing
- Chemical Analysis
- Scanning electron microscope
- EDX micro analysis
Furthermore, Diehl Metall Schmiedetechnik carries out special analyses as part of development projects and advises customers on all issues relating to materials.
Quality management – products of the highest quality
Diehl Metall Schmiedetechnik has a certified quality management system according to international quality standards. Quality management is an integrated part of the process chain for safeguarding all aspects of quality assurance in the interests of our customers. The focus is on the continuous optimization of our business and production processes.
