Everything Protected and Coated.

The use of our well tried and tested coating systems and coating solutions adds the substantial finishing touch to various technologies and guarantees a significant additional economic value for numerous areas of application.

Everything Protected and Coated.

The various areas of application and technologies in which the use of our high-tech coating solutions has already proven its worth are as numerous as our miscellaneous PVD and DLC coatings.

Machining.

Coating of machining tools allows for use with higher cutting values, reduction in the formation of built-up edges as well as increased endurance thus yielding lower cutting and set-up costs. Due to the fact that high temperatures can be transmitted through the swarf without impeding the blade’s performance thanks to oxidation resistance, thermal stability and hot hardness of the individual coating systems, PVD coatings are also ideal for areas in which high temperatures are common such as high-speed cutting (HSC) and dry processing.

Metal Forming.

Through using PVD coating, one can improve the functional properties of metal forming tools in a targeted manner in order to achieve more efficient production processes. Thanks to their excellent hardness, coatings protect functional surfaces, cutting edges and drawing radii against abrasive wear and reduce galling. Coated tools produce work pieces of consistent quality and remain fully functional for longer. Increased productivity and endurance, reduction in unit costs and processing times.

Punching.

Coatings are also used on punching tools to reduce abrasive wear and galling as well as to increase endurance and thus, improve productivity.

Plastic Prozessing.

In the field of plastic processing, PVD coatings reduce mould contamination / facilitate removal of contaminations. Thanks to prolonged melt fluidity, coatings allow for improved mould filling, facilitate removal from the mould and offer excellent wear protection when abrasive plastic is used. Coated forming tools generally show improved operating behaviour.

In plastic processing, also DLC coating systems are used in many areas along the entire production process – from injection moulding through cutting and extrusion to removal from the mould. Especially in injection moulding and particularly in thermoplastic processing, more and more moving parts are being protected with anti-friction carbon coats and can thus operate without lubrication and are entirely maintenance-free. No matter if it’s injection moulds or tools, sliding surfaces on mechanically engineered parts, forming areas, cores, slides or injectors – DLC coatings reduce mould contamination, wear due to abrasive plastic and surface corrosion, yields significantly improved removal from the mould and increase the dry and emergency running properties of tools and construction elements. This allows for prolonged endurance at reduced maintenance intervals and a significant rise in productivity.

Metal Machining.

In injection moulding applications, the right PVD coating protects cores, mould inserts and mould cavities against wear and corrosion. This allows for better removal from the mould, less core rupture and mould damage, surface imperfections materialise later. Reduced production costs thanks to increased endurance, lower tool costs as well as less need for maintenance and cleaning.

Thanks to the low deposition temperatures of diamond-like carbon, coating of non-ferrous metals poses no challenges whatsoever. Thus, DLC coating systems are excellently suited for materials such as aluminium, brass, copper or low-tempered steels. Especially in the area of forming and machining tools for aluminium machining, the use of DLC coatings has gained importance due to the fact that they prevent galling and reduce flash during the cutting of aluminium sheets.

Tribological Applications.

Thanks to outstanding wear resistance combined with excellent friction and anti-adhesion properties, our DLC coatings are the ideal solution for the refinement of construction elements and components subject to high levels of tribological stress – meaning surfaces in relative motion effecting each other. In many areas of mechanical engineering, for instance, one needs parts whose surfaces are not only low in friction but also extremely hard and durable.
The typical areas of application of these carbon coating systems are: Sliding and roller bearings, engine and gearbox components (e.g. piston rods, camshafts, worm drives, cogs, valves, piston rings and bolts …), automotive small batch parts, hydraulic and pneumatic components, sealing and guiding elements as well as micro-mechanical components.
