Netstal Earns ISO 17025 Accreditation for Medical Injection Molding Machine CalibrationNetstal Earns ISO 17025 Accreditation for Medical Injection Molding Machine Calibration

Netstal Maschinen AG has received accreditation from the Swiss Accreditation Service 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 opens up additional competitive advantages for users from the medical technology sector. 

"With ISO 17025 accreditation, we have reached a significant milestone in the history of Netstal,” said CEO Renzo Davatz. “It makes us the first and only manufacturer of medical injection molding machines to receive accreditation as a calibration laboratory.” Davatz is also a member of the Executive Committee of the KraussMaffei Group, which brought Switzerland-based Netstal under its wing in 1992. 

Calibration in accordance with ISO 17025:2017 is available immediately, said Netstal in the news release, 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,” said Daniel Wipfli, Product Manager, Controls and Digital Products. “With risk-based calibration by our qualified calibration personnel and the use of traceable and calibrated measuring devices, we ensure verifiable measurement accuracy of the relevant sensor signals within a defined measurement uncertainty range.” The company’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 an audit," added Wipfli.

For injection molders with high quality requirements outside the medical technology sectors, Netstal offers calibration based on VDMA 24470, through which relevant parameters are checked against associated typical tolerances. The tolerance ranges are defined in relation 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 clamping platen parallelism are supplemented by Netstal with screw position and column force distribution parameters. "By checking the injection position, we ensure that this quality requirement can also be met. The symmetrical distribution of the column forces is an important basic requirement for the longevity of any machine," explained Wipfli.
