Electric share of German passenger car market reaches new high
Electric cars achieve a new record share of the German car market Total market, domestic production and exports show falling figures In August a total of 193,300 passenger cars were newly registered in Germany. That was 23 percent less than in the same month last year. In the first eight months of this year, 1.8 million cars were newly registered, which was 2 percent higher than the 2020 result. However, the number of newly registered cars was down by over a quarter in comparison with the same period in 2019, so the German passenger car market is still a long way from its pre-crisis level. New registrations of electric passenger cars rose by 61 percent in August to 53,400 units, with e-cars accounting for 27.6 percent of all new registrations. This was a major step up from the previous record from December last year. New registrations of battery-electric cars (BEVs) added 80...
Gaskets and seals for electric vehicles
There are more than 1.3 billion motor vehicles worldwide today, one billion of which are passenger cars. This number is expected to rise to two billion by 2035. This poses major challenges not only for Germany, but for almost all industrialized and emerging countries: Traffic-related emissions of CO2, air pollutants and noise are a headache, and dependence on oil imports continues to grow. Electromobility is the key to climate-friendly mobility and innovation worldwide. The operation of electric vehicles produces significantly less CO2, especially when combined with renewably generated electricity. In addition, electric vehicles with their energy storage systems can compensate for fluctuations in wind and solar power in the future, thus supporting the expansion and market integration of these unsteady energy sources. In electric vehicles, seals are used in battery systems, which are produced by Dr. Dietrich Müller GmbH. The battery packs in vehicles are located in panels consisting of an...
Flatbed die cutting vs. rotary die cutting
Differences between flatbed die cutting and rotary die cutting Die cutting is a popular manufacturing process used to quickly and effectively cut parts from electrical insulation materials, thermally conductive products, engineered films and gaskets. Commonly, die cutting is associated with materials such as rubber, plastic, foam, paper and even cardboard. There also punching machines that work with metal. However, Dr. Dietrich Müller GmbH does not process metals into stamped parts. Die cutting is a broad term that encompasses several other processes. Today we will compare two of these processes, flatbed die cutting and rotary die cutting. Flatbed die cutting vs. rotary die cutting Both die cutting processes have their similarities: Both produce drawing parts, however, these two manufacturing processes also have their own unique characteristics. 1) What is rotary die cutting? When you first think of rotary die cutting, you should think of a high-speed process that focuses on tolerance and accuracy. Rotary die cutters...
die cutting vs. water jet cutting
die cutting vs. waterjet cutting Today, there are more cutting methods than ever before. While sawing was once the primary option for cutting industrial materials, today there are nearly a dozen viable options. To ensure project accuracy, efficiency and cost-effectiveness, any cutting method intended for a particular part should play an important role in the design phase. Two of the most common cutting processes offered by Dr. Dietrich Mueller GmbH are punching and waterjet cutting. Both manufacturing processes each have advantages that are suitable for specific requirements. Waterjet cutting Waterjet cutting, as the name implies, uses jets of water under high pressure to cut soft materials. When harder materials such as metals or plastics are to be cut, an abrasive material can be added to the water to allow the waterjet to cut these materials as well. This method offers several advantages over punching and other cutting methods: clean cuts low heat tolerances Advantage of...

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...
light+building
In view of the world-wide situation caused by the Corona pandemic, and the prohibitions on events and travel restrictions associated with it, Messe Frankfurt has decided, jointly with its partners – ZVEI and ZVEH – and with the Trade Fair Advisory Council, to defer the eleventh Light + Building and to hold it, in accordance with its normal sequence, from 13 to 18 March 2022. Due to the present Corona crisis it had already not been possible to hold Light + Building 2020, originally scheduled for March, for which reason the decision was reached to postpone the world’s leading trade fair for lighting and building services technology to the later date of 27 September to 2 October 2020. Messe Frankfurt, together with its partners, then initiated appropriate measures to carry out the event postponement as well as possible. Having considered the current situation again, and ten weeks after the initial...
Mica: a traditional material for the electrotechnical industry
What is mica? Mica is so called because of its gleaming and shiny appearance. The different types of mica can be easily distinguished by their colour. Muscovite has a light and phlegopite a dark appearance. Mica, also called mica, is a mineral extracted from mines. It belongs to the monoclinic crystal system and consists of alkali-containing aluminium silicates of various compositions. Among a multitude of natural mica types, only two are considered for technical use: muscovite and phlogopite. Muscovite, also called potassium mica, is a potassium aluminium double silicate. The colour is ruby red, also white, green or brown. Phlogopite, also called magnesia mica, is a potassium-magnesium-aluminium-iron double silicate. The colouring is similar to amber, after which it is also called amberg mica. Historical facts about mica Mica were already mentioned in 1546 by the mineralogist Georgius Agricola. Where mica was readily available and inexpensive, but glass was too expensive, the mineral...
