By the shape of the cast product, it is divided into round bar mould, hollow tube mould, and shaped mould.   Our company specializes in manufacturing various kinds of graphite moulds for the up-drawing and horizontal continuous casting graphite mould, and matching with the liners, jacket, graphite flake. Graphite mechanical seals, a variety of special and conventional coated with graphite crystal, the level of law governing graphite, gold and silver smelting graphite crucible, the product is widely used in gold, silver, copper, aluminum, semiconductor, metallurgy, machinery, petroleum, chemical processing industries. Mainly used for copper smelting copper rods, brass, copper and other products with high temperature, high strength, anti-oxidation properties, long service life   We can produce various kinds of graphite moulds as requested by you.   Graphite mould for up casting Graphite mould for up casting The mould is used in continuous up casting of copper tube, copper rod and strip, the graphite mould is with low air leakage rate, low air hole rate, high strength, high heat conductivity and extreme smoothness (Ra0.08) and results the casted tube or billet with smooth surface and be free of crack and air hole. The lifetime is twice of common graphite products.   Graphite molds Materials index:  1.Content: 99.99% 2.Density: 1.87g/cm³ 3.Compressive strength: 65mPa 4.Shore hardness: 55 5.Porosity: 15%   C content Density Compressive strength Shore hardness Porosity Materials index 99.99% 1.87g/cm³ 65mPa 55 15%    Application:   1.
