Casting mold, Chen Hua machinery (certified), castings

Casting machine bed casting process production, should follow pouring hot baked, low temperature casting principle. Because raise the temperature of liquid metal in favor of completely melted baked inclusions, slag floating gray castings, easy slag and degassing, reducing machine casting slag and porosity defects; pouring a lower temperature, it will help reduce the metal liquid gas solubility, liquid shrinkage and high temperature liquid metal cavity surface for baking, to avoid holes, sticky sand and shrinkage and other defects. Therefore, to ensure the full mold casting cavity premise xiasha, try pouring a lower temperature. During operation of the liquid metal from the ladle called injection mold casting. Improper operation will cause insufficient water pouring, cold shuts, porosity, shrinkage and slag machine casting defects, and cause personal injury. Casting is relatively early humans to grasp a metal thermal processing, about 6,000 years old. BC has entered China about the heyday of bronze castings between 1700 to 1000 years ago, the technology has reached a very high level. Casting is casting the liquid metal into the shape of the part of the casting cavity adapted to small castings, wait until the cooling and solidification to obtain parts or rough approach. [1] is more than the original cast material which is solid but is heated to a liquid state metal (for example: copper, iron, aluminum, tin, lead), and the mold material may be sand, metal or ceramics. In response to the different requirements, the methods used will be different. Casting - melting metal, manufacturing mold, and pouring molten metal into the mold, after solidification to obtain a certain shape, size and performance of metal parts cast molding method is that the metal blank to conform to certain requirements of the melting and pouring of liquid into the mold inside, the cooling and solidification, the Qing get a predetermined shape, size and performance after the whole process of casting processing. Rough casting due to the near-forming, or machining to achieve a small amount of free machining purposes to reduce costs and to some extent reduces the production time. Casting is one of the basic processes of modern equipment manufacturing industry. Casting mold, Chen Hua machinery (certified), castings supplied by China Machinery Co., Ltd. Qingdao Chen.
