Conclusion Prospect of nodular casting manufacturers

This design is mainly to study the lost foam casting in casting, its main contents are the analysis of casting technology, the choice of parting surface, the choice of pouring position, the choice of casting technology parameters, the design of pattern, pouring system, sand box production line. To complete these contents, I need to read type materials. This process makes my knowledge more systematic gains a lot.

In the design process, we need to draw relevant drawings, including hand drawing of sand box, drawing of three-dimensional casting drawing with UG, drawing of combined box drawing, template drawing casting process drawing with AutoCAD. This makes me familiar with able to use these computer graphics software.

Through this design, I have a further understanding of EPC. EPC (Lost Foam Casting) is a new casting technology which uses polystyrene as the main molding material to make the mold. Lost foam casting is very practical, which can only meet the single production mass production, but also can cast complex parts which can be cast by traditional sand mold. The pattern used in EPC is EPS which is easy to be heated vaporized. The casting surface of the cancelled core making department the cylinder accessory supplier has a high precision of bright clean dimension, greatly improves the production efficiency. However, EPC also has some shortcomings, because each casting needs a foam plastic model, the foam plastic model can only be used for a single time, so it is necessary to have a certain mold size, thereby improving the production cost. Because the pattern of EPC has certain density strength, it is easy to integrate easy to deform, which is conducive to large-scale production.

China is in a period of vigorous development, the demand for industrial development is urgent. Since the 21st century, China's total annual output of cylinder accessories wholesale has been in the forefront of the world. However, the leading foundry production is a headache for the environment, energy conservation sustainable development, which is a good thing. Since the people's Republic of China, with the dream of becoming a powerful industrial country, China has been recklessly developing industry manufacturing industry, but has ignored the harm to the environment of our country. Therefore, the environment has been deteriorating recently, which is the environmental debt owed by industrial casting. At the same time, unreasonable misuse of resources has also caused serious waste of resources in China. Therefore, China's cylinder accessories manufacturers must adhere to sustainable development, do blindly seek development give up environmental governance, should be calm, scientific, positive responsible for the environment.

The rise development of EPC technology has greatly improved production capacity, reduced labor intensity improved product quality. However, EPS, the material used for EPC pattern, produced more residual carbon due to high-temperature pyrolysis, which only has an impact on castings, but also poses a threat to the environment. At the same time, EPS material is cheap has a broad market. Therefore, enterprises have a large demand for EPS energy The crisis will also be a major hit for enterprises.

In the future EPC technology, we can continue to develop new replacement materials for environmental protection, combine EPC with other new foundry processes to create new composite processes, so as to further improve the quality production efficiency of EPC Castings reduce the harm to the environment. EPC involves a wide range of areas, mainly including chemical, plastic mechanical casting. We should integrate them, which requires the relevant departments of our country to strengthen division of labor cooperation, coordinate operations, give full play to the overall advantages, avoid low-level repetition, improve the overall level strength of China's EPC.
