Custom solutions for every application
Know-how and quality
Our products are produced and supplied in constant conformity to the very highest quality standards. This quality is assured by our certified quality management system, approvals issued by inspection organisations of global repute and wide-ranging measuring and inspection systems, including tests and analyses performed in our on-site materials laboratory.
Responsibility lived out every day
Responsibility for our employees, the environment and the climate is a central element of our corporate philosophy. This responsibility is integrated into all our daily activities and implemented by means of a comprehensive management system and systematic occupational and environmental safety provisions.
Our production facilities
The expert toolmakers in our fully equipped on-site toolmaking shop are the guarantee of high-quality forged products. This is where customers' requirements and needs are made reality in the form of tailor-crafted dies and matrices that precisely reproduce the customer's specifications. Forming-process simulation ensures maximum dimensional accuracy and absolutely flawless results. Depth of production extends from roughing machining of the die block to machining on NC and CNC lathes and milling machines and/or 5-axis milling centres. On-site tool assembly and die welding facilities, backed up by close consultation with the forging experts, ensure exact meeting of customer specifications.
Optimised materials, production and organisational efficiency, combined with the special strength properties achieved in our products thanks to detailed attention to correct grain orientation, are what make our drop forgings special. We ensure this by means of preliminary shaping equipment installed upstream the forming machines in all production systems. Schmiedag GmbH's range of machines and other equipment includes automated feed systems, pre-forming and handling systems, industrial robots and highly efficient heat-treatment facilities.
Our presses and forging hammers:
- 160 kNm and 320 kNm counterblow hammers
- 45 MN spindle press
- 31.5 MN eccentric press
Machining and surface finishing
Our products cover the entire value chain, from the blank forging up to and including the ready-to-use component. Produced in optimally harmonised processes, delivered reliably and on time, either roughing, finished and/or ready-to-use machined. Our machining and heat-treating facilities include:
- Machining centres
- CNC lathes
- Induction hardening systems
- Surface finishing (painting/coating)
The foundation stone for the present-day Schmiedag GmbH is laid when Peter Dallhaus establishes a forge in the Eckesey district of Hagen.
Grüntaler Eisenwerke AG is founded on the existing forge site.
Schmiedag AG is set up as a firm of mechanical engineers. The company assets include an integrated forge and a number of production facilities.
Acquisition of Schwinn AG, a die-forging company registered in Homburg an der Saar originally founded in 1905.
Both companies are acquired by Hoesch AG.
The Hagen and Homburg locations are acquired by Ascometal S.A.. The ASCOFORGE group is formed.
Schmiedag GmbH becomes part of GMH Gruppe.
GMH Gruppe's forging technology companies
The GMH Gruppe forging technology companies produce customised open-die and die-forged components at six strategic locations, pooling their know-how and using high-efficiency melting and production processes. The benefits for you: faultless products delivered on time even at short notice and precisely matching your individual needs.
