Application scope: From the advantages and limitations of centrifugal casting mentioned above, it can be seen that centrifugal casting is suitable for specific large-scale production castings.At present, centrifugal casting has become a widely used casting method in China, especially in the production of some pipe and ……

What is pressure casting? Pressure casting is a casting method that rapidly fills the metal mold cavity with molten metal under high pressure and solidifies under high pressure. This method is commonly known as die casting. The characteristics of pressure casting: (1) The casting production process is simple, easy to m……

Aluminum brass and aluminum bronze are also known to have significant differences in color, process characteristics, and uses. Aluminum brass is a special brass (aluminum brass) formed by adding aluminum to copper zinc alloys. 1. The purpose of aluminum brass is that aluminum in aluminum brass can improve the strength ……

Recently, I saw many friends on Zhihu who are not in the field of casting asking, "What is the role of copper alloy smelting?"?, Today, let me give everyone a good understanding. There are three main types of raw materials for copper alloy smelting: cathode copper (electrolytic copper), geometric waste generated during……

The worm gear reducer has low energy consumption and superior performance, with an efficiency of up to 96%. The high steel cast iron box helical gear with low vibration, low noise, and ribs is made of forged steel material, and the surface is carburized and hardened through precision machining to ensure shaft paralleli……

The bearing shell is the part in contact between the sliding bearing and the shaft, which is very smooth. It is generally made of wear-resistant materials such as bronze and anti friction alloy. In special cases, it can be made of wood, plastic or rubber. Here are four things to pay attention to when selecting bearing ……

The following methods are commonly used for casting copper gears: 1. Sand casting 2. Wax casting 3. Gravity casting 4. It is recommended to use lost foam casting. The casting process is very unique, and the quality of the products cast is more exquisite than that of ordinary casting methods. Dongguan Sanhe Machinery Co……

Worm gears and worm mechanisms are often used in situations where two shafts are interlocked, the transmission ratio is high, the transmission power is not high, or intermittent work is required. Widely used in machine tools, automobiles, instruments, metallurgical machinery, and other machinery or equipment, the reaso……

Phosphorus bronze is usually a type of bronze with tin and phosphorus as the main alloying elements. Contains 2-8% tin and 0.1-0.4% phosphorus. Mainly used as wear-resistant parts and elastic components. Main grades: China QSn10-1, QSn6.5-0.1, QSn7-0.2, QSn8-0.3, QSn4-0.3, QSn4-3, ZQSn10, ZQSn5-5-5, ZQSN6-6-3, etc. 1. ……

Copper sleeve casting is the process of melting copper alloy into a liquid that meets certain requirements and pouring it into the mold. After cooling, solidification, and cleaning treatment, it obtains castings with predetermined shapes, sizes, and properties. As the casting blank is almost formed, it can avoid mechan……

1. The aluminum content of aluminum bronze generally does not exceed 11.5%, and sometimes an appropriate amount of elements such as iron, nickel, manganese are added to further improve performance. Aluminum bronze can be strengthened through heat treatment, with higher strength than tin bronze and better resistance to ……

Tin bronze: 1. Tin bronze is a bronze with tin as the main alloying element. The tin content is generally between 3-14%, mainly used for making elastic components and wear-resistant parts. 2. The tin content of deformed tin bronze does not exceed 8%, and sometimes elements such as phosphorus, lead, and zinc are added. ……
