Several factors of hot pressure graphite mold damage

1. Broken: Graphite mold directly contacts the matrix powder containing diamond. The contact surface is in a high pressure state. The hardness of diamond and graphite mold is too poor. The surface of the mold that is in contact with diamond tool head will produce concave pits.Second, the type of damage: During the sintering process, the matrix powder infiltrates into the oxidation gap of the graphite mold under the melting state, resulting in the adhesion between the tool head and the mold, making it difficult for molding. The repeated attack of the mold can remove the mold, which causes the lack of edges and metal pit in the mold.Third, the wear size of graphite molds is very poor: some substrate powder will be squeezed out of the mold surface in the melting state to attach to the graphite material. Before using the mold next time, metal residues must be removed manually, which causes the shape and size of the mold to exceed the tolerance.Fourth, surface oxidation and cracking: Becau

What is the function of flake graphite in coated sand?

Coated sand refers to molding sand or core sand covered with a layer of solid resin film, and the use of flake graphite in coated sand is used to prevent peeling during the use of coated sand. Below, we will provide a detailed explanation of the functions of flake graphite in coated sand.The flake graphite used in coated sand is used as a lubricant in coated sand. The flake graphite used in coated sand can play a role in lubrication and high temperature resistance. The requirements for flake graphite used in coated sand are to have good lubrication performance and high melting point as a lubricant. And the flake graphite used for coated sand is made of natural flake graphite with good lubrication, which has been purified and processed to increase its carbon content.
