Lubricating films for cold forming, with and without ZWEZ-Coat separating film
Even today, the classic "soap lubricating film" in combination with a zinc phosphate coating is still the most important lubricating system, not only for the massive forming of steel, but also for the drawing of wire, tubes and profiles. However, the extremely increased demands on the tribology of such cold forming processes have led to important innovations in the field of lubrication technology. Today, these fulfil all current requirements with respect to the degree of forming, as well as to the accuracy of dimensions and surface quality.
ZWEZ-Lube Z with less coating thickness performs much better, minimises tool
contamination and increases the durability of tools.
ZWEZ-Lube MD has replaced the powder application of molybdenum disulphide.
Because of the aqueous, dustfree application by immersion, this technology perfectly integrates into the filming process of phosphating as the final "wet-in-wet" coating stage. ZWEZ-Lube MD is applied at the large scale.
ZWEZ-Lube PD is the latest development that covers an area of performance between soaps and solid lubricants. Because of their specific properties, these aqueous special polymers replace the conventional soap products partially very advantageously and extend well into the suitability range of molybdenum disulphide, thus ZWEZ-Lube MD.
