Quality management
In 2009, the company Kunststoff-Technik Kuhn GmbH was certified for the first time according to DIN EN ISO 9001: 2008. Regular successful monitoring and repeat audits confirm the high quality thinking and aspirations.
In 2018, recertification according to DIN EN ISO 9001: 2015 was successfully carried out.
The basis for a functioning quality management system is clear leadership, a high quality awareness of all employees and constant checks before, during and after production. This represents an important component of competitiveness and ensures the fulfilment of the high quality requirements of our customers. Of course, upon customer request, we will prepare initial sample test reports, factory certificates and test reports.

Steps of quality assurance
-
1. Material
We source our high-quality engineering plastics directly and exclusively from the market-leading semi-finished product manufacturers. This guarantees high material quality and availability. Approved material, e.g. : EU / 10/2011, FDA, REACH, RoHS are available from stock.
-
2. Production
During the manufacturing process, constant quality controls are carried out and recorded by our technical staff and our QA employees on the machines.
-
3. Finished parts
The final inspection is carried out by our three QA employees with their great expertise, many years of experience and modern testing equipment. This is the basis for a detailed review and documentation.
Quality Assurance
The examination of the high-quality plastic parts is carried out in a separate air-conditioned room at a room temperature of 20°C. This ensures an accurate, comparable and meaningful test.

Tolerances on Machined Plastic Components
Plastics are subject to different physical laws than metals.
The up to 10-fold greater thermal expansion, the volume change due to moisture absorption and subsequent dimensional changes due to the reduction of residual stresses in the long-term behaviour preclude the guarantee of narrow dimensional tolerances.
