Precision Casting Is The World Leader In Casting Industry

Wuxi Hoohi Engineering Co.,Ltd | Updated: Oct 27, 2017

Precision casting is the use of sophisticated modeling methods to obtain accurate casting process in general. Including: investment casting, ceramic casting, metal casting, pressure casting, Lost Foam Casting. Which is more commonly used is the investment casting, also known as lost wax casting: the use of suitable melt-casting materials (such as paraffin) to build the mold; in the mold on the repeated wear refractory coating and sand-resistant sand, hardening shell and dry; And then the internal melting of the melt melted out to obtain the cavity; roasted shell to obtain sufficient strength, and burn the residual melting material, casting the required metal materials; solidification cooling, shelling after the sand, to obtain High-precision finished products. According to product needs or heat treatment and cold processing and surface treatment.

Precision casting, also known as lost wax casting, its products are sophisticated, complex, close to the final shape of the parts, can be processed or rarely processed directly on the use of investment casting is a nearly net shape of the advanced process.

China ancient: Prince Wu Ding, copper ban, bronze lions, etc., are investment casting masterpiece. Since the 20th century, 40 years of investment casting for industrial production, half a century has been developed at a faster rate. Especially in Europe and the United States to develop rapidly. The investment casting is used in all sectors of the aviation, weapons sector, and is used in almost all industrial sectors, especially in electronics, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical equipment, pumps and valves. In recent years, China has developed rapidly.

The development of investment casting technology makes the investment casting not only produce small castings, but also can produce larger castings. The largest size of castings is nearly 2m, while the minimum wall thickness is less than 2mm. At the same time the investment casting is also more sophisticated, in addition to linear tolerances, the parts can achieve high geometric tolerances. The surface roughness of the investment casting is also getting smaller and higher, reaching Ra0.4μm.

Precision casting is the world leader in the casting industry, as the casting industry in the field of high-tech representatives, precision casting must play its exemplary role and take the lead, but the precision casting to play these two roles is the premise of its own strong, so our country Precision casting should be given priority to the development of development needs of established goals and development goals, precision casting industry development goals are the following aspects:

First, the completion of the growth mode by the labor, resource-intensive to the technology capital-intensive changes from extensive pollution to green intensive type of change, the product quality, variety, quantity and the world's advanced level, the proportion of high-quality materials Increase, the entire precision casting plant production efficiency, economic efficiency doubled; environmental pollution has been effectively managed, initially built with the environment co-ordination of China's casting materials industry system.

Second, the formation of a number of reasonable structure, the overall level of high combination of research and development and education and training base, can continue to transport professionals to the enterprise, and constantly develop high-quality, high-grade casting new varieties of materials to meet the growing Need, and gradually increase the intensity of technology exports.

Third, to complete the industrial structure adjustment, out of a number of low technological level, poor product quality, serious pollution, poor economic efficiency of small precision casting plant, the formation of a relatively concentrated "small giant" and "Star Enterprise" to achieve "professional Of large-scale "production. Especially to the emergence of one or two world-renowned enterprises to compete with the backbone of enterprises, their high level of technology, sophisticated technology, well-funded, advanced management level, can continue to provide high-end market, high-quality casting materials, market share High rate.

Precision casting industry if to achieve the above development goals, strengthen their own, then the precision casting industry will be able to play in the casting industry pioneer model and take the lead in driving the development of casting industry.
