Heat treatment in a vacuum
For perfect material properties & surfaces

Every application places special demands on the material. Often these properties can only be realised by heat treatments such as annealing, hardening and tempering. REUTER TECHNOLOGIE offers ovens of various sizes for this purpose. Depending on the method, we can reach temperatures of up to 1600 °C. We protect oxygen-sensitive materials with an atmosphere of nitrogen, argon or hydrogen.

We remove impurities from the surface of your components through heat treatment processes in a vacuum. Our ovens are electronically controlled and monitored. This means that different processes can also be combined with each other. For this purpose, we offer suitable additional processes such as packaging in N2-flooded containers. Ask us, we will be happy to advise you!

Heat treatment processes:

  • Hydrogen degassing annealing
  • Stress-relief annealing
  • Demagnetisation annealing (reduction of permeability)
  • Diffusion / solution annealing
  • Recrystallisation annealing
  • Soft annealing
  • Normal annealing
  • Hardening and tempering of stainless steel
  • Hardening and tempering of high-alloy steel
  • Vacuum annealing

Low-particle cleaning
We clean, pack and assemble in the clean room

REUTER TECHNOLOGIE has an 80 m² clean room of ISO class 7 (~100,000). This contains a separate area in which assembly can be carried out under ISO Class 3 (~10,000) cleanroom conditions. Our employees have been trained by an independent institute for cleanroom behaviour and are regularly qualified. Use this expertise and our systems for dust-free cleaning, assembly or packaging of your components.

  • Assembly of components and assemblies under clean room conditions up to ISO class 3
  • Cleaning and clean room compatible packaging of components before shipment
  • Characterisation of the component surfaces with regard to particle number and size including measurement protocol
  • Test report of the particle measurement, if specification available

If your components are assembled outside a clean room but are later used in clean rooms, cleaning and low-particle packaging is usually required.

REUTER TECHNOLOGIE offers an in-house developed, low-particle ultra-fine cleaning system. The achievable results correspond to a surface cleanliness of SPC class 5.

Our offer:

  • Fine cleaning of component surfaces according to customer specifications
  • Measurement protocol regarding particle load in the size range 0.3 µm to 10 µm (optional)
  • Test report of the particle measurement (if specifications available, sample on request)
03

Surface treatment
Final touch for the perfect result

We use various cleaning processes for the finishing of surfaces. These include ultrasonic cleaning, glass bead blasting or polishing. Depending on your requirements, we optimise the entire cleaning process until the desired quality is achieved.

In cooperation with our regional partners, we are also able to offer you various treatment processes such as copper plating, gold plating, silver plating, anodising, hard coating or vibratory grinding (barrel finishing) or electroless nickel plating. Please do not hesitate to contact us.

Helium leak test
Leak test up to the UHV zone

When it comes to the equipment for our helium leak tests, we rely on the world market leader Pfeiffer Vakuum. Our employees are also playing in the same league. We ensure their qualification through regular certification by an independent institute.

For fast, direct leak tests, such as checking water leaks in cooling lines, we use the helium overpressure test. The detection limit of this method is a leakage rate of 5∙10-8 mbar∙l∙s-1.

With the helium spray method as a more elaborate, more precise procedure, we are able to detect leakage rates up to the range of 5∙10-12 mbar∙l∙s-1

06

Residual gas analysis
Investigation of the outgassing behaviour of your components

A residual gas analysis shows whether your component or material is suitable for use in a vacuum. At the same time, the efficiency of different cleaning processes can be compared and qualified.

REUTER TECHNOLOGIE has been using qualitative residual gas analysis by means of mass spectrometry for many years in the development of its own assemblies and components as well as, for example, in the qualification of solder materials.

07

Materials testing
Microscopically assured quality in the material composite

The quality of a joint is determined by the properties of the individual parts in the microscopic structure. For the analysis of the microstructure, we use the most modern technologies. This includes high-resolution micrographs and X-ray and ultrasound analysis, which we carry out in cooperation with competent partners.

With the help of material testing, we ensure that you can rely on top-performing products. This means that you only use materials that meet the highest standards of joining quality.

08

Permeability measurements
Testing intrinsic magnetism and low remanence

REUTER TECHNOLOGIE has been using permeability measurements for many years in the development of its own assemblies and components. For example, to determine the shielding of a pipe or chamber against external magnetic flux densities. We offer these measurements as a service.

Our services in the field of permeability measurement:

  • Permeability measurement in the range µr = 1.00001 to 2.000 with the Forester probe
  • Alternative: Measurement of the permeability of components using the Ferromaster from Stefan Mayer Instruments in the range µr = 1.001 to 1.999
  • Measurement protocol with sketch of the measurement points (optional)
  • Test report on submission of a specification (optional)

The movement of electrical charge carriers in a vacuum is disturbed by the intrinsic magnetism of surrounding components. For high-tech applications such as accelerator technology or in surface analysis using electron beams (SEM, LEED, LEEM), therefore, only materials that have no intrinsic magnetism, are low in remanence and have a low permeability may be used. While intrinsic magnetism and remanence (induced intrinsic magnetism due to brief exposure to an external magnetic field) are relatively easy to investigate using an applied permanent magnet, testing permeability is considerably more complicated.

09

Particle measurement
When highest purity matters

For applications where the highest level of cleanliness is required, REUTER TECHNOLOGIE has been testing its own parts and components for their surface cleanliness by means of particle counting for many years. A high-quality particle counter is available for these investigations, which uses laser scattering to detect particles blown off the surface according to size and number. The measuring range covers particles in the size range from 0.3 µm to 10 µm.

  • Measurement of component surfaces with regard to particle contamination in the size range 0.3 µm to 10 µm
  • Measurement protocol Counts per bin (optional)
  • Measuring points specified by customer or defined according to measuring standard
  • Test report (optional) (if specification available, sample on request)
