New type resin sand coating advantages: new foundry coating is based on traditional foundry coating is improved, the adjustment, can effectively prevent the high temperature liquid metal oxide, and casting and high temperature chemical reaction in the process of liquid metal contact. And can absorb nitrogen, sulfur and carbon gases. To thoroughly solve the adhering sand castings, sand holes, coarse, stomatal, inclusions (residue), ball mill, iron cast steel sulfurizing crack, increase carbon defects, etc. The main products are: general cast iron, grey cast iron parts, ball mill cast iron, carbon steel, alloy steel, Gao Luogang, high manganese steel, stainless steel, copper alloy, aluminum alloy, magnesium alloy.
high strength, plasticity, toughness, wear resistance, resistance to severe heat and mechanical shock, resistance to high temperature or low temperature, corrosion resistance and dimensional stability, etc.In order to meet the conditions of use of these changes, ductile iron, many existing brands, to provide the mechanical properties and physical properties of a wide range.
r of the top should be 2 times bigger than the sprue, and generally directly on the mould making in the modelling.More than medium-sized castings, flood basin for the basin shape, often after generally made independently in casting.High quality castings to set up special slag in the sprue cup device.
