Gaskets: important components
It is often overlooked what a decisive influence seals and gaskets have on the function and service life of machines and systems. Proportional valves, for example, are limited in their function and endangered even from dirt particle sizes of 3 μm. Rolling bearings, on the other hand, are considerably impaired in terms of their service life by water content in the lubricant of just 200 ppm and can be damaged. Seals basically fulfill two tasks for rotating or linear components: On the one hand, they protect the sensitive inner life of the machine elements from contamination, and on the other hand, they protect the environment from leaking lubricants or hydraulic operating fluids, for example. Criteria for seal and gasket selection In principle, three criteria apply when selecting the right seal: 1. Design specifications: Here, it is important to consider how the components behave towards each other. 2. Chemical and physical loads: Here it must be...

Insulation films for busbar systems
Ahlhorn | 09.09.2020 The expansion of the charging infrastructure in Germany and the higher performance of electric vehicles present new challenges for manufacturers of conductor rails, charging infrastructure and battery systems. High dielectric strength, partial discharge resistance and small component sizes are the requirements of the automotive industry and plant manufacturers for charging stations for electric vehicles. For highly integrated components with high field strengths, the homogeneity of the applied layer is particularly important, since variations in the layer thickness have a direct effect on the dielectric strength of the material. The dielectric strength is largely dependent on the diameter and dielectric properties of a material. For the production of multilayer current-carrying systems, film technology is mainly used for the insulation of conductive layers. The film technology is characterized by high homogeneity in the layer thickness. A high homogeneity of the layer is necessary because air inclusions can cause pre-discharges which ionize...
Adhesive tapes: an overview
What are adhesive tapes? Adhesive tapes are a combination of a material and an adhesive film and are used to join or bond objects together rather than using fasteners, screws or welding. The use of adhesive tapes instead of mechanical fasteners makes it possible to simplify manufacturing processes. In addition, adhesive tapes can protect surfaces so that the surface is not damaged when fasteners or screws are used. Adhesive tapes are also used to provide electrical insulation, dissipate heat or seal against media. Adhesive tapes are good solutions for automated product manufacturing, while liquid adhesives are messy and time-consuming because they must be sprayed or rolled onto the surface before bonding. What are adhesive tapes made of? Adhesive tapes consist of a material called a carrier material (e.g. paper, plastic film, fabric, foam), coated with an adhesive and covered with a release liner if required. The adhesive-coated carrier is then wound into a jumbo roll. The...

LED technology offers many advantages
LED technology has become indispensable in the world of lighting, as it offers so many convincing advantages that no one can ignore it. With their luminous flux, LED lamps can replace all luminaires today - from outdoor luminaires to ceiling luminaires and wall luminaires. And in addition, many LED lamps are also dimmable, so that users can adjust the brightness of their spotlights themselves. With LEDs, savings can be made because energy consumption is 90 percent lower than with incandescent lamps. LEDS are an energy-saving lighting solution that does not use any mercury at all and, thanks to their long life, produce little waste. They are also long-lasting (LEDs have a life of up to 50,000 hours). LEDs are much more efficient than traditional forms of lighting, yet they generate heat. This heat can have a negative effect on the LED and must therefore be dissipated to ensure that the benefits of...
