Quality Control

Product quality directly depends on the quality of process. Quality assurance must begin in the very first phase of the product creation process and cover all following phases. This holistic view of quality assurance, involving all aspects of design, production, testing, packing and conformity with both internal standards and externally set specifications, is the basis of our quality management. This is reflected in the approvals of ISO 9001/2008 & ISO 17025.
