« What problems arise from insufficient oil-water separation? » Puddles shimmering with gasoline like a rainbow—what might seem intriguing can quickly become expensive. When oil and water are not properly separated, the mixture can enter the sewage system, and thereby …

« Removing Stains and Discolorations From Lightweight Metal » Aluminum is a non-precious metal, meaning it reacts readily with oxidizing agents. When exposed to air, aluminum quickly forms a dense layer of aluminum oxide on its surface. This layer prevents …

Cold forming is a metalworking process where materials are shaped under significant compressive or tensile forces  with or without minimal preheating. This distinguishes cold forming from hot forming, with the dividing line being the recrystallization temperature. Formation of Material Microstructure …

Steel is found in nearly every aspect of daily life—houses, bridges, tools, and machines. While  it is not a lightweight metal, steel is relatively easy to shape and provides tremendous structural strength. Pure steel, however, cannot be used directly as …

« Passive and Active Corrosion Protection – We explain the differences » Passiver und aktiver Korrosionsschutz umfasst alle technischen Maßnahmen, die dazu dienen, Werkstoffe vor der Zerstörung durch Umgebungseinflüsse zu schützen. Der Sauerstoff und die Feuchtigkeit in der Atmosphäre setzen …

The term “emulsion splitting” encompasses various methods applied in wastewater treatment. Emulsions are mixtures of liquids that do not dissolve into each other. Emulsifiers are necessary to create a stable emulsion. When it becomes necessary to separate the liquids, for …

« How Car Parts from Fenders to Center Consoles Get Their Paint » Painting plastic parts is challenging because plastics repel most liquids and are difficult to wet. In the automotive industry, more frequently, parts are being made from plastic …

« Overview of Phosphating Processes » Phosphating refers to surface treatment processes that create specific protective layers on metal surfaces made of iron, zinc, or manganese. These layers are electrically insulating and contribute to corrosion protection, improved paint adhesion, or …

« How to Prevent Metal Discoloration » Some minerals in nature stand out due to their beautiful, iridescent surface. This effect can also be observed on metal surfaces – which in industrial metal processing is sometimes desired, but in other …

« Proper Disposal of Used Coolants » Metalworking relies heavily on the use of coolants. These cooling lubricants prevent tools from overheating and help remove debris from the work area. Even with proper maintenance, coolants eventually lose their effectiveness and …
