Extruding Dies

Extrusion dies are basically thick, circular steel disks containing one or more openings to create a profile. 

NANOKER manufactures ceramic extrusion dies for the non-ferrous metal forming industry (copper, brass, nickel). Our extrusion dies can be used for bars, tubes or profile extrusion.

KA-EDM

Ceramic Matrix Electroconductive Alumina Composite

Electroconductive Alumina Composite (KA-EDM) is manufactured by pressure-assisted sintering (SPS). It is a high toughness electroconductive alumina based composite and suitable for EDM machining. The main properties of KA-EDM are: Suitability for extreme hardness applications, very good dimensional stability, excellent chemical resistance in the most demanding environments.Electroconductive Alumina Composite (KA-EDM) is manufactured by pressure-assisted sintering (SPS).

Formats

NANOKER makes round dies but other forms are equally possible (rectangular, oval, square, hexagonal). The minimum – maximum dimensions we can offer are an internal diameter of 2 mm and an outter diameter of 120 mm. We are at disposal of the customers to understand their needs and provide the best possible solution. For more details of products and services or to specifically discuss your needs, please contact us.
