GRAFE is an expert in coloring translucent plastics Decades of experience, the highest level of technical know-how and state-of-the-art technical equipment - these are the three pillars on which the comprehensive expertise of the GRAFE GROUP, Blankenhain, in the coloring of transparent engineering plastics rests. "The requirements for dispersion and homogenization are much higher for transparent materials than for opaque colorings," explains sales manager Lars Tonnecker. "Therefore, a compound is a better and cleaner solution than a masterbatch when it comes to product manufacturing. This is because defect patterns on the component, such as uneven color distribution, streaks and concentration differences, can be avoided or eliminated, since there is no need for additional metering of the masterbatch at the factory." "Whether headlights, taillights or displays - colored transparent plastics are mostly used in lighting applications. For this, there are precisely defined wavelength ranges from the manufacturers that must be adhered to and from which there must be no deviations," adds project manager Elke Milus. "We can adjust our compounds so that each batch corresponds to the other with minimal tolerances, with the highest reproducibility and thus the best quality." GRAFE has also recently invested extensively in its laboratory equipment and now has, among other things, a high-resolution spectrophotometer for measuring transmission in different wavelength ranges (UV/VIS/NIR = ultraviolet/visible/near-infrared). Thanks to its higher optical resolution in an extended wavelength range from 350 to 1,050 nanometers, the instrument even measures in five-nanometer steps instead of the usual ten-nanometer steps and is thus much more precise.

Complex inorganic pigments providing high UV, weather and temperature stability for high performance applications.

In the aerospace industry, high-performance plastics with exceptional mechanical, thermal and chemical properties are used.

MKV has decades of experience in the compounding of engineering and high performance plastics and can handle a wide varitey of additives, fillers and masterbatches. The MKV develops and tailors its compounds to the specific customer needs.

The customized compounds from Delta Kunststoffe are specially tailored to the various processing methods and requirements. We take into account both the properties of the base plastics and the influence of our modifications in order to adapt all formulations individually to the respective requirement profile. This applies, for example, to color compounds, compounds for special applications, construction materials and all materials that meet the latest regulatory requirements.

pal plast is expanding its range to include compounds containing up to 100 per cent recycled content from qualified post-consumer recycling (PCR) sources.

Compounds for injection moulding and extrusion. pal plast will present material grades with controlled, adjustable viscosity and stable processing characteristics, suitable for the manufacture of dimensionally accurate injection-moulded parts as well as sheets, profiles and pipes.

New flame-retardant compounds will also be presented as a preview at Kuteno. These materials are currently under development and are designed for technical applications where increasing fire protection requirements are crucial. The aim is to combine functional safety, processability, and, in the future, recyclability.

From 2024, we will be offering a service for non-destructive testing of various components with our ‘industrial computed tomography’ measurement service. Thanks to our experience and outstanding technology, we can not only provide you with volume models, but also real problem solutions. Industrial computed tomography (CT) is revolutionising quality assurance and product development in industry. This advanced technology enables non-destructive, three-dimensional scanning of workpieces, components and materials. By precisely detecting internal structures and defects, industrial CT offers unrivalled insights into material properties. Our industrial computed tomography solutions are designed to meet the highest standards of accuracy and efficiency. They enable detailed analysis of components and products. From manufacturing inspection to failure analysis, CT technology provides comprehensive insight into the quality and integrity of components. With a state-of-the-art CT scanner and user-friendly software, we offer customised solutions for various industries, including automotive, aerospace, electronics and medical technology. Our systems provide precise 3D reconstructions and enable a virtual representation of components, allowing companies to detect defects early and optimise product development.
