Degaussing services

Maurer Magnetic AG offers customers in the field of demagnetization (same as degaussing) specialized services. The offer includes:
– On-site degaussing services
– In-house degaussing services
– Rental of demagnetizers and measuring instruments
– Troubleshooting in the field of magnetism
– Training sessions on demagnetization and magnetism

On-site degaussing services
Maurer Magnetic AG offers to solve difficult demagnetization jobs on site, on the basis of many years of experience and using proprietary demagnetizing equipment. Call us for the power supply required on site for a specific job.
We are in a position to demagnetize parts of most different shapes and dimensions quickly, efficiently, and fulfilling the most demanding requirements. Talk to us, and together we will find a solution.

   Demagnetization of powder presses
Modern powder presses need for the smooth processing of metallic powder, adapters and tools with very low residual magnetism levels.
– High magnetic fields on the tool surfaces of the powder press are causing the metallic sinter powder to clump or adhere. Thus the filling of forms is troubled and the cycle
time and quality of the produced parts is
negatively affected.
– The wear of tools with high residual
magnetism levels is increased, because of abrasive effects of the sticking metal
powder between the tool surfaces.

   Appropriate demagnetization process
The massive tools and adapter plates made of hard steel require a strong and voluminous AC field to be demagnetized with sufficient depth effect. Conventional plate or hand held demagnetizers are in most cases useless for this task.

Maurer Magnetic AG is using for such tasks the mobile demagnetizer MM DM with flexible demagnetizing cables. Large units or machines are demagnetized reliably and permanently with a short demagnetizing pulse of a few seconds duration. If necessary, these machines or units can be magnetically adjusted by our experts to eliminate static fields in a defined area of the machine.

Demagnetization of tools and machinery
Hardened tool steel, tight tolerances and fast cycle times are increasing the demands in the field of remaining magnetism on machine tools. By significantly reducing residual magnetism on ferromagnetic tools, a sustained improvement in the following points is achieved:
– Adhesion of residual metallic material or
particles on the tool
– Wear of tools due to abrasive effects of
metallic particles-
– Unwanted magnetization of the produced
parts

Demagnetization before welding processes
Magnetic field strength above a critical intensity is affecting the weldability. Well-known interferences are:
– Arc welding procedures are sensible to
high magnetic field strengths. Welding in
presence of magnetic fields may cause
magnetic arc blow. Arc blowing is strongly
reduced below field strengths of 16 A/cm
(=20 Gauss).
– In arc welding with filler wires, sticking
of the wire to a side is caused when
significant magnetic fields are present. The sticking is minimized below field strengths
of 8 A/cm (=10 Gauss).
– In electron beam welding, the quality of
the welding is strongly affected by
magnetism. At field strengths well below
2 A/cm (=2.5 Gauss) the disturbing
influence on welding is minimal.


A number of cases of on site and in house degaussing operations are documented in our reference-list

In-house degaussing services
Maurer Magnetic AG also provides short-term in house degaussing services. Different demagnetizing machines in our technology centre are ready to remove residual magnetism from any kind of ferromagnetic parts.

We are able to comply with very high quality requirements. On request we provide a certificate to the degaussing-service.

We are able to handle individual workpieces of up to 1600kg. Bigger units should generally be demagnetized on site.

Rental service of Demagnetizers
Maurer Magnetic AG manufactures a complete line of industrial demagnetizers and magnetic measuring instruments. Standard equipment is available for rental. When customers need to make own degaussing operations or tests for a limited time, the rental of a demagnetizer is the right solution.

Troubleshooting
Our qualified specialists provide troubleshooting and help you to achieve your targets. Maurer Magnetic AG draws on a wide experience of solving magnetism related tasks in any kind of manufacturing industry.

Training sessions
For interested customers, we provide trainings on the topic of magnetism in our technology centre or at the customer site.
