Precision Casting Is A Precise Modeling Method To Obtain Accurate Casting Process

Precision Casting is the general term for precise casting techniques with precision modeling methods. Precision casting is the use of precision casting metal forming objects obtained by the smelted liquid metal, pouring, injection, suction or other casting methods into the mold prepared in advance, after cooling and so on, the resulting A certain shape, size and performance of the object.

Precision Casting include: investment casting, ceramic casting, metal casting, pressure casting, lost foam casting. One of the more commonly used is investment casting, also known as lost wax casting: the selection of appropriate material (such as paraffin wax) made of melting mold; repeated in the melt on the fire-resistant coating and spreading sand refractory sand process, hardening shell and drying; Then melting the inner melt to obtain a cavity; roasting the shell to obtain sufficient strength, and burning off the remaining molten material; pouring the required metal material; solidifying and cooling, Accuracy of the finished product. According to the needs of the product or heat treatment and cold working and surface treatment.

In 2015, China's precision casting production exceeded 2.2 million tons.

In recent years, the downstream demand field of the precision casting industry in China has been constantly expanding, and the demand for precision casting parts has been on the rise. In 2015, the market scale of China's precision casting parts industry exceeded 110 billion yuan.

China Casting Development Forecast

At present, China has formed a number of fine casting industries that are gradually becoming internationalized in technology and management and are familiar with the international market. They have led to the rapid development of the industry. Gross Output Value of Castings in 2012 / Thousands of US Dollars China accounts for 28.4% of global output China's huge market provides ample space for the development of the casting industry.

1, the growing domestic market China's rapid economic development makes the casting market growing domestic, such as the rapid development of the automotive industry led to the production of automotive precision castings and brand rapid increase in product development, housing construction makes the demand for construction hardware Surge, investment enterprises in China directly from the procurement of spare parts, the original international market orders into the domestic market orders.

2. Export Increase Year by Year After more than 20 years of hard work, some enterprises have been able to mass produce machine parts with high precision and high quality aerospace precision castings. The company is capable of challenging commercial parts in terms of technology and cost performance, and its export volume has been increasing year by year. With the deepening of global economic integration and global procurement, exports will continue to grow rapidly. According to the import and export data of the Customs as a product of casting, the export volume of various types of castings in China in 2012 was 1,978,000 tons, slightly lower than the volume of 2,056,000 tons of various types of castings in China in 2011. The total export volume of China's castings in 2012 The amount of 2.97 billion US dollars, compared with the total amount of China's castings in 2011 was 2.81 billion US dollars a slight increase.

3, castings instead of sand castings, forging a vast market One of the advantages of precision casting is the ability to produce a variety of alloys and very complex, thin-walled castings, castings with high dimensional accuracy, low surface roughness, and can achieve little or no cutting Processing, this is sand casting and forgings can not match. As the demand for parts increases, more and more sand castings or forgings will be replaced by castings. With the continuous improvement of China's precision casting industry chain, continuous improvement of technology, downstream demand for precision casting parts growing demand, we can see the next few years, China's precision casting production will continue to show a steady growth. It is estimated that by 2021, China's precision casting production will be close to 4.6 million tons. 2016-2021 forecast production of medium-halogen precision casting China's rapid economic development makes the casting market growing domestic investment, such as the rapid development of the automotive industry led to the rapid development of automotive castings and brand products, the development of housing construction makes the construction Hardware demand surge, investment enterprises in China directly from the procurement of spare parts, the original international market orders into the domestic market orders. The demand for precision cast parts in the downstream demand area is only increasing. Visible, the next few years, China's precision casting industry will continue to show a steady market growth. It is estimated that by 2021, the market scale of precision casting industry in China is expected to approach 285 billion yuan.
