Types and Applications of Precision Casting

Currently, China’s exports of precision casting molds are primarily concentrated in Europe, North America, Japan, and South Korea, and for many companies, the export volume of molds accounts for over 30% of their total production value. From the perspective of our country's macroeconomic policies, market development, and both international and domestic demand, the market for large and medium-sized complex precision casting molds and die-cast parts is extremely vast. Considering our country’s macroeconomic policies and market development, the sales market for large and medium-sized complex precision casting molds and die-cast parts, both internationally and domestically, remains very large.

According to national media reports, precision casting molds in China not only attract domestic users but have also strongly drawn the attention of automotive giants such as General Motors in North America and Chrysler in the USA. With the continuous improvement of China’s mold manufacturing technology and the gradual perfection of process technology, coupled with the strong price advantage of molds exported from China to Europe for automobile oil and chassis die-casting molds, even amid recent global economic downturns, the future domestic production and sales of precision casting molds are expected to continue to rise. It is reported that precision casting molds in China not only attract domestic users but also significantly draw the attention of automotive giants like General Motors in North America and Chrysler in the USA, and these companies have repeatedly sent inspection teams to Chinese enterprises, prompting mutual agreements and cooperation intentions. The molds exported from China to Europe for automobile oil and chassis die-casting molds are widely recognized by foreign investors due to their strong price advantage, advanced design, and excellent manufacturing quality, resulting in repeated additional orders. Therefore, it is clear that the international market for Chinese precision casting molds remains vast.

The characteristics of precision casting are also reflected in the decorative industry, and precision casting applications are commonly used in addition to engineering projects. Civil machinery equipment also relies on it, such as piping—stainless steel thin-walled pipes, where precision casting is required for pipe installation and connection. For instance, in urban water supply systems, installing stainless steel thin-walled pipes requires the use of precision casting. Therefore, let's discuss: What are the types of highly corrosion-resistant precision castings?

The high corrosion resistance in precision casting generally refers to 316L material precision castings. Compared to conventional 304 material pipes, the corrosion resistance of 316L pipes is significantly higher. For general pipeline installations in aquatic environments or buildings, 316L material precision castings are used, which are not prone to rust, even when the chloride ion content is high.

At the same time, 316L precision castings with high corrosion resistance are used in seawater desalination equipment to prevent pipe corrosion and extend service life. Precision castings also include components such as 45° elbows, 90° elbows, straight connectors, reducing connectors, T-joints, cross joints, and eccentric reducers. Additionally, these precision castings come in different types such as double press, ring press, grooved, and socket weld connections.
