Quality management


Our high quality standards cover all processes: Consulting, extrusion, mechanical machining and delivery in the exact quantity, the defined quality and on-schedule. We practice the Total Quality Management System, which gives our employees at all levels responsibility and involves them in continuous optimisation. Our quality standards have been recognised with the ISO 9001 certificate. In addition to this, independent test centres can perform audits. Another international standard that defines and guarantees quality management requirements: Thermoplastic materials are delivered in accordance with quality standard DIN EN 15860.

Thermoplastic materials are delivered in accordance with quality standard DIN EN 15860.

We produce in accordance with the tolerances for plastic per DIN 7168 medium and/or DIN 2768 medium.

We verify the product quality of our semi-finished products and finished products with control measurements of random samples and final testing. A one hundred percent quality control of an order including documentation is available on request. All measurement and testing equipment is monitored regularly, its calibration is documented in test reports. On customer request, we deliver our products with measurement test reports.

Ultrasonic tests
Ultrasonic tests are performed regularly for non-destructive testing of semi-finished products for shrink holes, inclusions and porosity. Ultrasonic testing of semi-finished products can generally be performed during the tests if commissioned by customers.


The REACh regulations per EU Directive 1907/2006/EG has been valid since 01/06/2007, replacing the European Chemical Law valid prior to that.

REACh stands for
R = Registration
E = Evaluation
A = Authorisation and Restriction
Ch = Chmicals

Among other things, the REACh regulation require that all substances (chemicals and preparations) produced in the EU must be pre-registered and registered with the European Chemicals Agency (ECHA). The REACh regulations apply for all chemicals and preparations.

Polymers are explicitly excluded from registration and assessment (per Article 2, Paragraph 9). As a result, plastic semi-finished parts and finished parts are not subject to registration.
