Lost wax castingIt is a relatively economical method of forming blanks, and can show its economical efficiency even more for parts with complex shapes. Such as the cylinder block and cylinder head of automobile engine, ship propeller and exquisite artwork. Some hard-to-cut parts, such as nickel-based alloy parts of gas turbines, cannot be formed without casting.

In addition, the size and weight of the cast parts are suitable for a wide range, and the types of metals are almost unlimited; while the parts have general mechanical properties, they also have comprehensive properties such as wear resistance, corrosion resistance, and shock absorption. They are other metal forming methods such as forging. , Rolling, welding, punching and so on. Therefore, the number and tonnage of blank parts produced by casting methods in the machine manufacturing industry are still the largest.

The materials often used in casting production include various metals, coke, wood, plastics, gas and liquid fuels, and modeling materials. The required equipment includes various furnaces for metal smelting, various sand mixers for sand mixing, various molding machines and core making machines for modeling and core making, and sand shakers and shot blasting machines for cleaning castings. Wait. There are also machinery and equipment for special casting, as well as many transportation and material handling equipment.

Guangdong alloy steel castingManufacturing has characteristics that are different from other processes, mainly due to wide adaptability, many materials and equipment required, and environmental pollution. Casting production will produce dust, harmful gases and noise that will pollute the environment, which is more serious than other mechanical manufacturing processes, and measures need to be taken to control it.

The development trend of casting products is to require castings to have better comprehensive performance, higher precision, less margin and smoother surface. In addition, energy-saving requirements and society's call for restoration of the natural environment are also increasing. In order to meet these requirements, new casting alloys will be developed, and new smelting processes and new equipment will appear accordingly.

While the degree of mechanization and automation of foundry production is continuously improving, it will develop more to flexible production to expand the adaptability to different batches and multi-variety production. New technologies that save energy and raw materials will be given priority for development,Guangdong carbon steel castingNew processes and equipment that produce little or no pollution will be valued first. There will be new developments in quality control technology in the detection of various procedures, non-destructive testing, and stress determination.
