Quality Management
In 2009, the company Kunststofftechnik Kuhn GmbH was certified according to DIN EN ISO 9001:2008 for the first time. Regular successful monitoring and repeat audits confirm the high quality striving and thinking.
In 2021, recertification according to DIN EN ISO 9001: 2015 was successfully carried out.
The basis for a functioning quality management system is clear management, a high level of quality awareness among all employees, and constant checks before, during and after production. This represents an important component of our competitiveness and ensures the fulfillment of our customers’ high quality requirements. It goes without saying that we prepare initial sample test reports, works certificates as well as test reports at the customer’s request.

Steps of Quality Assurance
-
1. Material
We purchase our high-quality engineering plastics directly and exclusively from the market-leading semi-finished product manufacturers. This guarantees high material quality and availability. Materials with approvals, such as: FDA, REACH, RoHS or according to Regulation (EU) No. 10/2011 are available from stock.
-
2. Production
During the manufacturing process, constant quality controls are carried out and recorded by our specialized personnel and our QA staff at the machines.
-
3. Final inspection
For the final inspection, our three QA employees have modern testing equipment at their disposal, in addition to their great expertise and many years of experience. This is the basis for a detailed inspection and documentation.
Quality Assurance
The testing of the high-quality prefabricated plastic parts is carried out separately in a climate-controlled measuring room, at a constant ambient temperature of 20°C. This ensures accurate, comparable and meaningful testing.

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