Metal Analysis

It is essential to analyse metallic materials used in order to define the performance of the beverage can both in respect of its interaction with beverages and also in filling, handling and storage processes.

Key focus is placed on examining the geometric, mechanical and surface properties. In this way we hope to ensure constant compliance with the product specifications in respect of filling volume, mechanical stability and stackability.

When changes are made to the starting material or packaging design as a result of technical developments, it is important to investigate the reactions of the container in great detail.  Compliance with product specifications is crucial to ensure the quality and performance of our beverage cans.

Geometric Properties

With the help of state-of-the-art measuring and analysis systems, geometric parameters such as wall thickness, can height or neck and flange contours can be precisely measured to within a fraction of a micrometer. This also applies to sophisticated 3-d geometries or deformations.  In this way we can ensure that innovations or product enhancements satisfy the high quality standard of our beverage cans.

Mechanical Properties

The Technical Center laboratory uses a wide range of processes to test products and basic materials.  These include material hardness, micro-hardness, tensile strength, roughness and tests to establish the deformation behaviour of the metals used. In this way we gain the knowledge about the materials required for quality assurance. For example, we can influence the mechanical properties of the product in a specific manner: adjust beverage can stability to withstand internal and axial pressure or the long-term stability of the beverage can.

Surface Properties

The surface properties of the beverage can are significant not only for the quality of the high-grade printing but also for problem-free filling and storage without any deterioration in  product quality. A wide range of measuring and analytical techniques are applied in the laboratory at the Technical Center to assess surface quality. These include light, fluorescence and electron microscopy, optical micro-topography techniques, colorimetry and state-of-the-art camera systems. Our specialists use the results of the measurements and analyses to optimise the surface and the coating qualities as well as the material properties. To do this, they access the most recent findings obtained from research work on surface properties. We also offer our customers a comprehensive service to resolve material and surface related issues.
