    Nodular cast iron GGG-70   Ductile iron is not a single material but part of a group of materials which can be produced with a wide range of properties through control of their microstructure. The common defining characteristic of this group of materials is the shape of the graphite. In ductile irons, graphite is in the form of  nodules  rather than flakes as in  grey iron

    Why resin sand casting 1. Good air permeability: after the high-temperature metal liquid is poured into the model, the model is filled with a large amount of gas, which must be discharged from the model. Otherwise, the casting will suffer from defects such as porosity and insufficient casting. 2. High strength: the resin sand must be strong enough to avoid collapse during molding,

    spheroidal ink casting The binder has a direct influence on the quality, production time and production cost of mold shell and casting in the investment casting industry. Because the industry for the quality of the adhesive has high requirements, some of the common adhesive can not meet the needs of industry, so the colloidal silica in investment casting industry has been greatly developed.
