Quality at the Grohmann Group

Our Commitment to Excellence

Cast. Create. Win.

At the Grohmann Group, quality is far more than a requirement – it is our daily motivation and the foundation of our success. As a leading company in aluminum casting, we uphold the highest standards to not only meet but exceed the expectations of our customers.

Whether safety-critical prototypes, series production, or precision components – we understand that uncompromising quality is essential for our customers’ success.

Excellence Beyond Our Certifications

Our numerous certifications demonstrate our consistent commitment to quality and information management. Independently verified on a regular basis, they underline our high standards of precision, safety, and efficiency.

But certifications are only the beginning: we focus on continuous process optimization, innovative technologies, and state-of-the-art testing systems to consistently meet our own standards – and the highest requirements of our customers.

Quality Management (ISO 9001 / IATF 16949 and VDA 6.1):

Our certified quality management system enables us to systematically meet the diverse and stringent requirements of the automotive industry and many other sectors. With our zero-defect strategy, continuous improvement, and strict implementation of customer-specific requirements, we ensure the highest level of quality – from prototype development to series production.

Information Security Management (TISAX):

With our TISAX certification (Trusted Information Security Assessment Exchange), we meet the strict requirements for information security, especially within the automotive industry. This certification guarantees our customers and partners secure handling of sensitive data – from product development to collaboration on complex projects.

Approval According to SVTI Standards:

Our production complies with the stringent requirements of the SVTI (Swiss Association for Technical Inspections). This approval underscores our commitment to the highest safety standards, especially in the manufacturing of pressure-bearing components and safety-critical applications.

Energy Management System (ISO 50001):

With our ISO 50001-certified energy management system, we continuously optimize our energy consumption and increase our energy efficiency. This not only reduces operating costs but also ensures resource-efficient and sustainable production.

Our Goal: Continuous Improvement

The constant enhancement of our processes is our commitment — and the key to maximum quality and efficiency. This is reflected not only in our comprehensive quality inspections but also in regular audits and the use of advanced software solutions.

  • Customer, Supplier, and Internal Process Audits:
    For us, audits are far more than control mechanisms — they are a central part of our corporate development. Through customer, supplier, and internal process audits, we identify optimization potential and continuously improve our workflows.
  • Digital Process Monitoring with CAQ Software:
    Using state-of-the-art CAQ software, we monitor, document, and analyze our processes in real time. This allows us to identify areas for improvement early and implement targeted actions to continuously enhance efficiency and quality.

We also use the software to create, manage, and publish our management documentation, ensuring transparent and well-structured process control. Our ongoing development secures the highest standards and sustainable efficiency – for us and for our customers.

Comprehensive Testing and Analysis Capabilities

With modern testing technologies, we ensure that our products meet the highest quality requirements. Continuous quality inspections throughout production allow us to detect and correct potential issues at an early stage.
Our capabilities include a wide range of testing and analysis methods to ensure maximum precision and safety.

Geometric Property Inspection
  • Coordinate Measuring Machine (CMM) – ensures precise compliance with dimensions and geometric tolerances.
  • 3D Measuring & Scanning Systems – enable highly accurate dimensional inspections and detailed analysis of complex components.
        Testing of Mechanical Properties
        • Tensile Testing Machine – analyzes mechanical properties and documents material strength.
        • Hardness Testing – determines the material’s resistance and overall quality.
        Metallurgical Analysis
        • Spectrometer – enables precise determination of the chemical composition of our materials and ensures consistent quality.
        • Metallography with Porosity Analysis – provides in-depth insights into the material structure and detects shrinkage cavities or inclusions.
        Surface Inspection
        • Crack Detection System – enables early identification of surface irregularities and defects.
        • Faro Measuring Arm – provides flexible, high-precision measurements directly within the production environment.
        • Optical Inspection Systems – allow detailed evaluation of surface quality.
        Non-Destructive Testing Methods
        • X-ray Systems – reveal hidden defects in cast parts without compromising their structural integrity.
        • Ultrasonic Testing – identifies internal flaws in materials that would not be detectable using other methods.

        Innovation and Sustainability in Production

        Our cast components are used in safety-critical areas such as engines, chassis systems, and structural parts. With innovative alloys and state-of-the-art casting technologies, we help reduce weight and CO₂ emissions – contributing to the mobility of tomorrow.

        At the same time, we combine the highest quality standards with sustainable practices: through our energy management systems, process optimization, and material recycling, we minimize our environmental footprint.
