Chemical industry

Casting is a hot manufacturing process of metal forming, that is: melting metal, manufacturing mold (core), pouring liquid metal into the mold and after solidification to obtain metal products (castings) with desired shape, size and performance. The casting industry always enjoys the title of "Mother of Industry" and occupies a very important position in the economy.


Casting products are widely used in various industries, such as, automobiles, mining, metallurgy, machinery, power generation, rail transit, ships, aerospace and etc. Castings is the core component of industries mentioned above.


There have 2 raw materials categories for castings: ferrous metals (cast iron and cast steel) and non-ferrous metals (aluminum, magnesium, copper, zinc and others). Although the global non-ferrous metal castings grows rapidly, black metal casting is still the mainstream. In recent years, the output of ferrous metal castings, such as , gray cast iron, ductile cast iron and stainless steel casting parts accounts for more than 80% of the total output. And in ferrous metal castings, gray cast iron is the main material. So does the main material of Chinese castings. The ratio of gray cast iron is about 41.8%, the ductile cast iron accounts for about 28.7%, the aluminum (magnesium) alloy accounts for about 14.5% and the rest takes 3.3%.


In downstream application, the automotive industry is the largest demand field for castings in China. The demand for construction machinery, casting pipes and pipe fittings and rail transportation industries has been increasing, while the demand for industries, such as agricultural machinery, machine tools and tools has been declining. At the same time, the export volume is gradually expanding every year and products are mainly exported to the United States, UK, Germany, India and other countries and regions.


At present, although China's casting production is far higher than other countries, the average output of single company is lower than that of western countries. China has a huge number of casting manufactures. In 2019, the number of casting manufacturers in mainland is about 15,000. Among these casting factories, 30%(about 4,500 factories), takes 80% of the total casting output.


China's casting industry is large but not so strong and only a few large-scale casting companies have competitive advantages in scale, technology and process. Their downstream applications involves two or more industries and these industries even refer to more subdivided applications. But large amount of middle and small casting factories are in full competition in low-end products. Actually their production tech and management level remains at the level of 10 years ago. Small casting companies only produce one or two single application products. Except for a few benchmark casting companies, it is difficult for the remaining companies to export castings directly because of hidden quality issues.


Investment casting

Investment casting is also called lost wax casting, or known as precision casting in China. And it is a universal name for the process of obtaining precision-sized castings. The products produced by this process are precise, complex and close to the final shape of the part and can be used directly without or with little CNC machining treatment. Comparing with the traditional sand casting process, the casting size obtained by precision casting is more accurate and the surface finish is much better.

(1) High precision: the castings has high dimensional accuracy, fine surface roughness value, the dimensional accuracy of the casting can reach to 4-6, and the surface roughness can reach to 0.4-3.2μm, which could greatly reduce the machining allowance of the casting and reduce production costs.
(2) Investment casting could be used for complex shapes and it is difficult to be processed by other casting methods. The wall thickness is close to 0.4mm and the minimum hole diameter could be less than 1.0mm.
(3) Carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy, high temperature alloy, titanium alloy and precious metal can be produced by precision casting. Since alloy materials is difficult to forge, weld and cut, it is ideally suitable for precision casting process.
(4) High production flexibility and strong adaptability; investment casting can be used for mass production but also be used for small batch or even single piece of production (but the production efficiency is quite low).
