Loss Of Graphite Material

The uniform particle diameter of the material directly affects the condition of the material discharge. The smaller the uniform particles of the material, the more uniform the discharge of the material, the more stable the discharge condition, the better the surface quality. For the surface, the precision is not demanding casting, die-casting mold, usually recommended the use of coarse particles, such as ISEM-3; for the surface, the higher precision of the electronic mold, recommend the use of uniform particle size of 4μm below the material, To ensure the accuracy of the processing die, surface finish.Graphite Material

The smaller the uniform particles of the material, the smaller the loss of material, the greater the force between the ion groups. For example, it is generally recommended that ISEM-7 is sufficient for precision die-casting and casting molds, but TTK-50 or ISO-63 materials are recommended for customers with high material requirements to ensure a smaller material loss To ensure the accuracy of the mold and surface roughness. The flexural strength of the material is a direct expression of the strength of the material, showing the tightness of the internal structure of the material. High strength of the material, the discharge loss resistance performance is relatively good, for the high precision electrode, try to choose a better strength of the material.Graphite Material

In the familiarity of the subconsciousness of graphite, graphite is generally thought to be a relatively soft material. But the actual test data and application shows that the hardness of graphite than metal materials. In the special graphite industry, the common hardness test standard is Shore hardness measurement method, the test principle and the metal test principle is different. Due to the layered structure of the graphite, it has a very superior cutting performance during the cutting process. The cutting force is only about 1/3 of the copper material, and the machined surface is easy to handle.

According to the statistics of the characteristics of the material for our materials, if the uniform particles of the same material, the resistivity of the discharge rate will be slower than the resistivity. Graphite Material

For materials of the same uniform particle size, the resistivity of the material, the strength and hardness will be slightly lower than the high resistivity of the material. That is, the discharge speed, loss will be different. Therefore, according to the practical application of the need to select the material is very important.Graphite Material
