The 33rd South China International Exhibition on Printing Industry

German SDS plastic and metal ink scraper

German SHEELON plastic doctor blade Suitable for use in new energy applications, coating machines, and flexographic printing. Specifically designed for new‑energy batteries; free of metallic particles. Made from plastic, it is gentle on the printing plate, resistant to corrosion, and can withstand temperatures up to 150°C. The standard model boasts a service life 1.6 times longer than comparable blades in the industry. It is compatible with both forward and reverse doctoring and is ideal for use with closed ink‑tank systems.

German "SHEELON" dyne pens and dyne solutions

German SHEELON DYNAPEN The Dynapen, also known as a surface tension test pen, corona treatment pen, or plastic film surface tension testing pen, is a tool used to measure the surface energy (dynes) of thin films, specifically designed to assess the effectiveness of corona treatment on such materials. Dynapens are available in dozens of different dyne ratings, with common values ranging from 22 mN/m to 72 mN/m. They accurately determine whether the surface free energy of films, plastics, metals, ceramics, semiconductors, glass fibers, and other materials meets the specified dyne levels, and can also verify whether the results of corona treatment satisfy required standards. This enables quick, intuitive assessment of material suitability for processes such as printing, lamination, or vacuum aluminum coating, thereby effectively controlling quality and minimizing losses caused by substandard materials.

UK "PILLARSHERMAN Schumann" Dyno Pen and Dyno Solution

UK "PILLARSHERMAN Schumann" DYN Pen This brand is the industry standard for DYN pens, with a history of approximately 60 years. It is used to measure the surface tension of materials (also known as the DYN value or corona pen). In everyday applications, most base materials require knowledge of their surface energy—expressed as the DYN value—before processing can proceed to the next manufacturing step.
