Ferdinand Bernhofer GmbH

Processes

Planning – simulation – optimisation proposals – joint agreement with customers – sample forging – realisation, incl. processing – quality assurance – aftercare

Due to conscientious, effective and highly sensitive planning, we ensure that the quality of the product is unique and that we are able to produce it for you in the most cost-effective manner.

Our principals are actively engaged in the development process, thus we guarantee the greatest levels of satisfaction and process effectiveness, both at product and process level.

As our customer, you benefit from our tradition of forging and our wealth of experience. We individually inform you of problems which could arise, supplying you with optimisation proposals in advance within the scope of project management. We discuss these issues together on an equal footing, with the most open and realistic attitude, and the process is driven forward by the means of common solution development.

Sample forging is another important element for finally commencing with the production process, using both customer-oriented and efficient coordination.

After the product has been manufactured and your idea has taken form, the Bernhofer team rounds off the service with competent aftercare – we accompany you at all process levels to ensure long-term, partnership-based cooperation.

Planning

Our core strength is tool construction with parallel or upstream construction.

With several workstations in construction, 2D-3D Visi-Series, ACAD - LT and CAM Work NC, with an ATOS 3D scanner and forging simulation software in 2D and 3D projects, we work using state-of-the-art technology at the highest level.

We are therefore able to develop your projects with the greatest possible accuracy or to proceed with last-minute changes in the nick of time.

The digital project result is finally realised using HSC machines.

 

Forging

After cutting the raw material to the required length, the components are forged on several semi-automatic forging lines. Constructing forging lines make it possible to use the optimum unit configurations for each case.

With our longstanding, competent and professional employees, the Bernhofer team has centuries of experience in the forging process, which is passed on from one generation to the next.

Work is currently taking place on a pneumatic air hammer, an AEG induction heating plant and 2 preforming units.

The 2nd hammer, a Lasco hydraulic drop hammer with gas heating and a hammer forge leaves no desires unfulfilled with regard to forging competence. It gives your ideas the shape you desire for further processing or lets the product become exactly what is required by the processing guidelines.

With two pressing groups, there is the option of directly tempering the finished components from the heat of the forge after deburring. Heat is generated by induction in all forging groups.

 

Quality assurance

In the sense of a delivering a qualitatively complete handling process, it is to be expected that the following processes are undertaken in-house: heat treatment, normalisation, soft annealing and high temperature ferrite-pearlite annealing and tempering. Everything in carried out in one place, not only to make your ideas take form, but also to guarantee the quality and safety required.

Sandblasting takes place in 5 plants. The 3 troughed belt plants handle the main part of the work, whereas 2 smaller plants are available for samples or low volume production.

Also occuring in 5 plants (Tiede and Interflux brand), all components which leave the Bernhofer drop forge have been previously subjected to the most precise crack test and inspected for strength. Pull and notched bar impact tests are conducted by our specialist partners at an external location, close to the production site in Höhnhart.

Post-processing or special processing of the components is conducted by our 10 professional partner firms close to the production site of the Bernhofer drop forge – we thus not only shape your ideas, but ensure the highest quality requirements under guarantee.
