A new grade is said to offer higher thermal conductivity and improved mechanical strength
Mersen develops graphite for specialised use in electrical and electronic applications, and the company will be presenting new developments at Euromold that include Ellor DS4C.
The company said it combines the advantages of an ultra-fine grain graphite with a copper impregnation. This is claimed to provide higher thermal conductivity and mechanical strength and thus support finer electrode design and lower wear. Very good machinability allows for detailed finishing electrodes.
Mersen’s EDM graphite goes from universal medium size grades to ultra-fine grain and covers roughing and high-end surface finishing. Good EDM results require not only the proper material selection, but also proper machine settings, which are mainly selected from experience and fine tuned as the work progresses. Mersen said its technical representatives – some of whom will be at the company booth during Euromold – can suggest the best grade for each application and will be able to assist with understanding the effects of different setting parameters.
