Our expertise: creating a lasting metal bond without melting

Thanks to our longtime experience in heat treatment, today our customer base includes customers from a wide variety of industries. Standard or series production, make-to-order parts or complex assemblies – maximum flexibility makes this possible:

  • Automotive supplier industry
  • Metalworking and machining industry
  • Mechanical engineering and tool and die making
  • Medical technology
  • Equipment and apparatus engineering
  • Electrical engineering
  • Precision mechanics
  • Furniture industry
  • Soldering connects metal to metal without the depth of the metal being reduced due to melting.
  • The properties of the metal remain largely intact when soldering.

Our services

  • State-of-the-art furnace conveyor systems solder components made of standard, stainless steel and non-ferrous metals without flux in an inert gas atmosphere.
  • Soldering and annealing in a high vacuum for even greater flexibility. Learn about the virtually limitless possibilities of a high vacuum oven.

Application examples

Material characteristics that change due to heat

Cleanliness that is not always visible to the eye: The heating and subsequent cooling of metal in an inert gas atmosphere leads to chemically uncoated workpieces that are free of oxide and oxide scale.

The recrystallisation annealing of cold-worked workpieces enables additional deformation. Afterwards, the material is once again smooth and the stress in the material is reduced, increasing the tool life of the deformation process significantly.

The perfect basis for your deformation process: recrystallisation annealing of cold-worked workpieces. Reduced stress and smooth to protect your tools and reduce microcracks.

  • During annealing, the materials are heated, their temperature is maintained and then they are cooled.
  • This type of heat treatment can be used to intentionally make changes to the structure of the material.

Our services

  • During annealing in our state-of-the-art oven conveyor systems, components made of standard, stainless steel and non-ferrous metals are gently heated and cooled off in an inert gas atmosphere with a defined temperature curve.
  • Vacuum annealing for large or deformation-critical components and components made of new, high-alloyed materials.

The first step towards quality

Component assembly is the precondition for flawless soldering results. We apply the most effective and efficient method based on the specific component.

We ensure cost and process reliability for small and large series by finding the best possible solution in collaboration with our customers and our tool and equipment partners.

Whether you need manual or fully automated pre-assembly, it is vital to use that we achieve added value for you.

  • Quality begins even before the actual soldering process.
  • When dealing with large workpiece quantities, we set up fully automated assembly lines.

Our services

  • 3D laser cutting for perfect cutting.
  • Pre-assembly for proper soldering with all common methods (TIG, MAG, CMT).
  • In pre-assembly, our individual parts are joined manually or using pneumatic, hydraulic and toggle lever presses.
  • Various solders, such as copper, nickel or custom solders, are positioned at the soldered joints using a robot, manually or in a semi-automated process according to the component geometry and quantity.

Application examples

Rigorous inspection and testing

After heat treatment, we provide reliable testing and inspection of your components. For the purposes of quality control and final machining, we have extensive measurement and inspection procedures.

  • Our inspection is adapted to the production process.
  • Upon request, we test every inspection result.

Our services

  • Underwater leak and differential pressure tests – simple and effective.
  • Flow rate testing with state-of-the-art measuring technology.
  • Bauteilvermessung mit Lehren und 3D-Messtechnik.
  • Marking your components through labelling, laser printing or scribe marking.

Application examples

Certified with the seal of quality

All of our work results are reproducible at any time with the identical level of quality due to continuous monitoring of the heat treatment process.

  • Certified quality.
  • Quality inspections with documentation and measurement reports.

Our services

  • 3D measurement for exact measurement of all components.
  • Grinding specimens – the most accurate examination with documentation that is usable in a court of law.
  • Hardness tests before and after heat treatment.
  • Tension force measurements illustrate the outstanding high strength of our connections.
  • Non-destructive alloy testing using x-ray fluorescence analysis – we also provide this service on site.
  • Our company is certified in accordance with DIN ISO 9001: 2015.
  • All quality examinations come with complete documentation by request.
