Quality control by experts
Quality Control and Ongoing Documentation
The entire hardening process ismonitored by a central control system to which the autonomous process controllers are connected. In this way, we comprehensively document the progression of all key parameters—such as temperature and pressure—for each batch. The advanced system is also programmed so that our employeescan onlyapproveparts thathave beenproperlyhardenedforshipment.Uponcustomer request, we issue anacceptance test certificate for quality approval.
In addition, we offer the following service inspections :
- Magnetic Particle Testing (MT) Level 2 (EN ISO 9712)
- Penetrant Testing (PT) Level 2 (EN ISO 9712)
ADVANCED TEST EQUIPMENT
Our fully automatic hardness tester accurately measures hardening depths, nitriding depths, and bonding layer thicknesses.
We perform these and other specific process inspections on metallographic sections , the preparation of which requires not only a high level of expertise but also top-of-the-line cutting and polishing equipment. 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 on the shape, size, and distribution of their crystals. Today, visual documentation is indispensable for modern quality control. At HTR, microstructural analyses at up to 500x magnification . The NIKON inverted microscope also enables us to analyze component damage such as cracks or fractures.
"Top-Quality Components in Record Time
“When it comes to quality assurance, we rely exclusively on laboratory equipment from leading manufacturers. The latest-generation devices allow us to perform a wide range of analyses with precision.”
Safety Through Material Characterization
To prevent the use of unsuitable materials and premature component failure, HTR conducts on-site material analysis using spectral analysis . Using a spark spectrometer from the market leader BELEC , we quickly and easily determine the exact alloy composition of your components. The size and weight of the component are irrelevant, as only tiny particles from the surface are spark-discharged via an argon probe. The resulting light spectrum is read and processed by state-of-the-art analysis software to provide the percentage composition of the alloy elements.
