Supply EPC member

EPC process: EPC (also known as solid casting) is a combination of size and shape similar to the foam casting model into a model cluster bonding, brushing refractory coating and after drying, dry quartz sand buried in vibration modeling, pouring under negative pressure, so that the model gasification, liquid metal model position occupied, the new casting method after the formation of casting solidification cooling. Casting four elements affect the design process of iron castings. During the design of the time, except in accordance with working conditions and metal material of the casting geometry and size determined, but also according to the angle of the casting process characteristics and the cast alloy to be considered for the rational design. For more casting news as our daily lives often used products, mainly affected by the following four factors: First, the design process of cast iron. During the design of the time, except in accordance with working conditions and metal material of the casting geometry and size determined, but also according to the angle of the casting process characteristics and the cast alloy to be considered for the rational design, to avoid casting deformation, cracking and components segregation and other defects. Second, the casting process to be reasonable, that is, according to the structure, size and weight of the iron castings to select the appropriate shape, making the core methods. And you want to chill, riser and gating system set up reasonable, in order to guarantee the quality of iron castings. Third, the casting excellent quality of raw materials or not. If the material quality of the metal charge, solvents, or other coatings Modificator not up to standard, it will make iron casting porosity, slag, sticky sand and other defects, thus affecting the interior and exterior quality cast iron. Fourth, the process rules to be reasonable. When the production castings, to continuously improve the skills of the workers, at the same time, to develop a reasonable process rules, so that the production process proper and reasonable. As a professional manufacturer of nodular cast, we advanced production equipment and production technology, products stable performance, excellent quality, with a higher price, consumers are welcome to visit to buy.
