Quality control from the experts
Hardness testing & spectral analysis
You can fully rely on our experts to ensure the highest product quality. We carry out comprehensive quality checks and analyses using state-of-the-art equipment.
Quality control and ongoing documentation
The entire hardening process is monitored by a central control system to which the stand-alone process controllers are connected. This allows us to fully document the progress of all important parameters - such as temperature and pressure - for each batch. The advanced system is also programmed so that only perfectly hardened parts can be released for delivery by our employees. At the customer's request, we can issue an acceptance test certificate for quality approval.
We also offer the following service tests:
- Magnetic particle testing MT level 2 (EN ISO 9712)
- Penetrant testing PT level 2 (EN ISO 9712)
Advanced testing devices
for a wide range of applications
Our fully automatic hardness tester precisely analyses hardening depths, nitriding hardness depths and compound layer thicknesses.
We carry out these and other specific progression tests on metallographic sections, the production of which requires first-class cutting and polishing equipment as well as a high level of expertise. The test results are automatically assigned to the respective order via our ERP system.
The quality of metals depends, among other things, on the alloying elements they contain as well as the shape, size and distribution of the crystals they contain. Nowadays, image documentation is indispensable for modern quality control. At HTR, microstructural analyses can be carried out with up to 500x magnification. The NIKON inverted microscope also enables us to analyse component damage such as cracks or fractures.
‘When it comes to quality assurance, we rely exclusively on laboratory equipment from leading manufacturers. The latest generation of equipment allows us to carry out a wide range of analyses with precision.’
Safety through material characterisation
To prevent the use of an unsuitable material and premature component failure, HTR carries out mobile material characterisation using spectral analysis. Using a spark spectrometer from the market leader BELEC, we can quickly and easily determine the exact alloy composition of your components. The size and weight of the component are irrelevant, as only tiny particles of the surface are scanned using an argon probe. The resulting light spectrum is read out and output as a percentage of the alloy elements using state-of-the-art analysis software.
