NETSTAL expands service offering with accredited machine calibrations according to ISO 17025

On December 2, 2021, NETSTAL Maschinen AG received accreditation from the Swiss Accreditation Service (SAS) as a calibration laboratory for injection molding machines in accordance with the international standard ISO/IEC 17025:2017. This entitles NETSTAL to perform risk-based machine calibrations at customers' facilities and to issue standard-compliant documentation. The new service offering opens up additional competitive advantages for users from the medical technology sector in particular, as they produce within minimum tolerance limits and have to prove this on a regular basis.


Since December 2, 2021, NETSTAL Maschinen AG is an ISO/IEC 17025:2017 accredited calibration laboratory for the measurands temperature, force, pressure, clamping force, length and speed. The accreditation number of the Swiss Accreditation Service SAS is SCS 0165. The official accreditation entitles NETSTAL to perform regular calibrations of injection molding machines for its customers. "With the ISO 17025 accreditation, we have reached a significant milestone in the history of NETSTAL. It makes us the first and only manufacturer of medical injection molding machines to receive accreditation as a calibration laboratory," emphasizes Renzo Davatz, CEO at NETSTAL and member of the Executive Committee of the KraussMaffei Group.

Securing competitive advantages in medical technology

Calibration in accordance with ISO 17025:2017 is available immediately and can be performed on-site at the customer's premises. "Our new service offering is primarily aimed at our customers in the medical technology sector. With risk-based calibration by our qualified calibration personnel and the use of metrological traceable and calibrated measuring devices, we ensure verifiable measurement accuracy of the relevant sensor signals within a defined measurement uncertainty range," explains Daniel Wipfli, Product Manager Controls and Digital Products at NETSTAL. NETSTAL's medical technology customers gain a competitive advantage in terms of quality and accuracy. "In the course of the calibrations, our technical experts create standard-compliant documentation that our customers can use in the audit," Daniel Wipfli emphasizes.

Machine calibration NETSTAL based on VDMA 24470 for customers outside the medical technology sector

Of interest to users with high quality requirements outside the field of medical technology: With the calibration "NETSTAL based on VDMA 24470", quality-relevant parameters are checked with their associated typical tolerances. The tolerance ranges has been defined with reference to commercially available injection molding machines. If the tolerances are adhered to, the machine is considered capable without mold and material. The VDMA parameters of barrel temperature, injection pressure, screw speed, clamping force build-up, clamping force reduction and parallelism of the clamping platen are supplemented by NETSTAL with the parameters of screw position and force distribution of the columns. "By checking the injection position, we ensure that this quality requirement, which is important from our point of view, can also be met. The symmetrical distribution of the column forces is an important basic requirement for the longevity of any machine," explains Daniel Wipfli. With accredited calibration in accordance with ISO 17025 and calibration based on VDMA 24470, NETSTAL offers its customers from all application fields the ideal service.
