Quality Assurance and Quality Control
Ensuring the quality of our manufactured components is our top priority and essential to our operations. Many of our components are used in highly precise and complex constructions, where flawless quality is a fundamental requirement. To meet all quality standards and ensure that the components we deliver fully comply with technical specifications, we utilize state-of-the-art measuring equipment.
Quality control holds a prominent position in our company, with a significant portion of our annual investment budget allocated to quality equipment. In 2019, we established a 3D measurement room equipped with a DEA ALPHA Classic measuring machine specifically for inspecting larger components, particularly welding assemblies. Components and assemblies measuring up to X = 2000 mm, Y = 5000 mm, Z = 1500 mm can be accurately measured with a precision of <0.1 µm. In 2020, we acquired two additional 3D measuring machines, ZEISS ACURA and ZEISS CONTURA.
In total, we operate six 3D measuring machines and four gear measuring machines, all operated by our skilled personnel in quality control.
The essence of our quality policy lies in the complete traceability of various processes, from the incoming inspection of raw materials to the final quality control of our components.
To ensure traceability of the raw materials used, documents for inspected and approved raw materials are marked with internal QC codes in addition to the raw material batch number. This QC code is assigned to the component being produced. This allows all departments involved in various stages of production to access information about the specific raw material batch, ensuring that only approved raw materials are used. Our final quality control consists of five phases:
- Phase One: Compilation of a list detailing tests to be conducted and dimensions/specifications to be checked.
- Phase Two: Comparison of the internal checklist with customer specifications, approved by a quality manager.
- Phase Three: Measurement and analysis based on the approved test specifications; measurement results are documented and internally logged.
- Phase Four: Comparison of documented measurement results with machine logs from the used measuring equipment to verify accuracy.
- Phase Five: Transfer of reconciled and approved measurement results into the final documentation format; final inspection reports are prepared. After preparation, these reports are reviewed and approved by a quality manager. Quality control is completed, and the documentation can then be transmitted to the customer.
A material certificate according to EN 10204 – 3.1 is included as standard with every order.
Our quality control processes and procedures are conducted in accordance with ISO 9001 standards and requirements. All subcontractors, such as raw material suppliers and coaters, undergo standardized quality audits before commencing collaboration to ensure that the services rendered or products delivered meet our company's and our customers' existing quality requirements.
