Hello. We at STEINEL AKTIVELEMENTE GMBH only have one aim: to produce the best cutting unit that there is for you. Again and again and again. Always identical, again and again. The convincing properties of our components are their excellent cutting quantities and unbelievable precision. We only deal with cutting units, they are the meaning of our work. We want to know everything about where they do their work, what processes they are involved in, and we want to deliver on time. We do everything to achieve these aims. Our modern production facility was built in Spring 2009, it is equipped...

We offer you Cutting units for tooling and mould construction Cutting units are the cutting and shaping parts using in punching, metalforming and injection moulding tools. This means that they are subject to the most stringent demands on precision and surface quality. Punches and dies are replaced several times during a tool’s lifetime and are thus considered wearing parts. Typical cutting units are e.g.: Cutting punches and cutting dies Bending punches and bending inserts Die stamps and forming inserts Initial materials are high-quality HSS steels, powder-metallurgical steels and carbides....

SPECIALIST KNOW-HOW Knowing what’s important Geometries PVD coating Material Punching sequence Surface quality Cutting clearance and waste protection Production engineering We know what’s important for punching, and are familiar with the details important for the production of long-life cutting units: • The choice of material is decisive for a stable process • ptimum cutting clearance combined with process-reliable waste protecO tion guarantees high availability and quality • he quality of the cutting edge surface has a decisive influence on the T quantity cut • PVD coating extends the...

All parts are exactly the same 15.06.2009 1 month later 5 years later 15.06.2009 3 months later 4 years later Thanks to our CAD/CAM processes we can guarantee 100% exchange- ability of the parts we produce. No matter when you need a spare part, the new part will be exactly the same as the cutting unit we last delivered, right down to the last detail, you can rely on that. We always manufacture precisely down to the last u.

Cutting units with PVD coating Longer service life for your cutting and metal-forming tools thanks to PVD coating Cutting and metal-forming tools are continually under a heavy load. The results:wearandcorrosionshortentheparts’servicelife.Theuseofcoating counteracts this effect. We achieve tool optimisation using the ION BOND method: During this process, titanium nitride (TiN) is precipitated from a cathode in a vacuum through light arc evaporation and deposited on the workpiece. TiN coating increases the service lives of HSS tools by between 300 and 800 per cent compared with non-coated or...
