Before delivery of the parts to the customer, the company is following a systematical process. Based on the customer’s requirements, DNK is supporting to design and to validate the model. Based on the geometry, the tools and the material will be prepared, and after the manufacturing, DNK is checking the product quality towards the requirements again to ensure that every product is manufactured as designed.
The required molds are manufactured in our facility with the help of 3D printing technology and our highly accurate CNC machines, which allow us to minimize quality risks and to react fast and flexibly on customers’ requirements.
Our steel molds are the best choice to produce constant quality also at large quantities. Furthermore, having the machines in-house, we are also able efficiently apply corrections or changes in the tools.
Proper material handling is essential in order to produce flawless products. This includes thorough documentation, supplier selection, material inspection and adequate storage
We select and audit our material suppliers conscientiously in order to ensure a stable process. Moreover, we independently conduct substantial test beyond the supplier test reports. Our materials are stored and monitored in dedicated rooms that provide the required climatic condition
DISCOVER THE QUALITY OF CARBON
The crucial process step of manual lay-up of the carbon layers takes place in controlled clear room to protect the product from any contamination and assure that the raw materials are used within their specifications. The DNK workers are well trained and are wearing suitable working gear including gloves.
Apart from carbon fiber, DNK is experienced in using other composites such as glass fiber as well as core systems like foams, honeycombs, and releasable cores that can be combined with carbon fiber.
In order to ensure stable product quality all our machines and instruments are being calibrated and checked on a yearly basis. The instructions to design department are followed step by step. Moreover, every product is tracked throughout the manufacturing process.
Final Test and Conformity Check
When manufacturing, we inspect the first sample (FAI) for compliance with the engineering requirements and design. We use non-destructive (NDT) as well as destructive (DT) methods to guarantee that the manufactured part is fulfilling the requirements.
Quality gates, quality control and adequate employee training are standard success criteria in our manufacturing process. To increase our level of quality continuously, we measure, label and track every product coming out of our manufacturing facilities. That allows us to learn which procedures performed the best and to provide the best support to our customers.
At the end of the manufacturing process, the products are tested with our professional and accurate in-house testing equipment and by the support of professional testing agencies like SGS and the laboratories of local universities.
