Product description

Introduction to circular graphite electrode

1. Adopts imported German jolt moulding machine, featuring: 1) Vacuum-pumping; 2) Low porosity; 3) Even texture; 4) High volume density.

2. Adopts ring type baking furnace with cover, featuring: 1) Good heat insulation effect, so that the products are heated evenly; 2) Stable internal structure; 3) High coking value.

3. Adopts lengthwise graphitization furnace, featuring: 1) High conductivity efficiency; 2) Even degree of graphitization; 3) Stable product quality.

4. Adopts CNC combined processing machines: 1) High machining precision; 2) Good product appearance; 3) The advantages of graphite electrodes are easy processing, high removal rate for electrical discharge machining, and low graphite loss. 4) Graphite electrodes can be easily machined and its machining process can be way faster than that of copper electrodes. For example, when adopting milling process to machine graphite, its speed will be 2-3 times faster than other metals, with no extra manual treatment required. But copper electrodes will need manual grinding.
