We have a comprehensive EDM Graphite program for all types of sink erosion applications.
From our head office and production facility located in Jonkoping we serve customers all over Northern Europe with a broad range of quality edm graphite materials. The graphite is stocked in form of blocks, plates, round bars, precision ground rods, sheets, tapered sheets, 3Ready-To-Run, precision ground sheets, foils, tubes and threading electrodes. From our own production with high throughput capacity we have the ability to deliver custom made products on short notice. Svenska Tanso AB will happily manufacture your specific electrodes according to your CAD files.


Carbon is to be found in nature as diamond, natural graphite and in various combinations, in solid, liquid and gas form. Amorphous carbon (missing crystalline structure) can be transformed into graphite and get a crys-tal structure when heated to high temperatures. Industrial production of synthetic graphite started at the end of the 18th century and the process has since then successively been developed. The raw material is composed of petroleum coke, carbon black, anthracite etc as well as filler and binding agents. Normally among 30 different raw materials are needed for the production of a complete programme of coal and graphite products. The raw material in the form of fine-grained powder is pressed in an isostatic press under a very high pressure. Afterwards the burning is done at a very high temperature of 900-1800°C and at a cycle time of 20-30 days. The next step is graphitising at which the material is converted into graphite and gets developed crystal structure. The temperature is 2500-3000 C and the cycle time about 15 days. The manufacturing process is an arduous task.
