Casting Key Of Auxiliary Materials For Foundry Auxiliary Materials

Direct expenditures include direct material (raw materials, auxiliary materials, spare parts, fuel and power, etc., direct wages (wages of production personnel, subsidies), other direct expenses (such as welfare costs); the cost of manufacturing refers to the various expenses incurred in the Organization and management of production, including factory, workshop management, Depreciation, maintenance, repair and other manufacturing costs (office, travel, insurance, etc.).Foundry Auxiliary Materials

Modern high-pressure modeling, injection molding, gas punching modeling, static pressure modeling and shock-free vacuum compression molding, and other new processes are also used to use clay wet sand as the premise. The implementation of a variety of new processes, so that the clay wet sand in the foundry production status is more important, but also to make the clay wet sand face many new problems, prompting us to the clay wet sand research continue to strengthen and deepen understanding. Nowadays, with the rapid development of science and technology, the demand for castings has been increasing in various industries, meanwhile, the requirements for casting quality are more and more high.Foundry Auxiliary Materials

Modern foundry, molding equipment productivity has been raised to an unprecedented level, if the performance of the sand can not be fully adapted to the specific production conditions, or can not effectively control its stability, consistency, then it will not be long before the casting plant buried in the waste. With the development of science and technology, at present, the use of clay wet sand foundry, generally suitable for its specific conditions of the sand treatment system, including: old sand treatment, new sand and auxiliary materials, sand mixing and sand-control. There are many changing factors in the clay wet sand system.Foundry Auxiliary Materials

If one or more of the key can be maintained within the scope of control, there may be problems in production. An effective sand treatment system, should be able to monitor the performance of sand, if there is a problem, should be timely to correct. Due to the different arrangement of sand treatment system in foundry plants, the equipment chosen is not the same, and it is not able to develop a common control method. Here, we intend to present some control points that have been widely accepted. After carefully understanding these points, the foundry can determine the feasible control method according to its specific conditions. And, as technology progresses and the actual capabilities of the plant, including people and funds, continue to improve control of the sand-type system.Foundry Auxiliary Materials
