Stainless steel casting ring
Dongguan precision castings are not unfamiliar to everyone, and the use of precision castings has a long history. In ancient times, people used Dongguan precision castings to make coin sacrificial vessels, weapons, things and some daily utensils. However, in modern times, Dongguan precision castings are mainly used for machine parts and the blanks may be directly used as machine parts. Dongguan precision castings are beginning to take up more and more shares of machinery products, and the amount is increasing year by year. The shape and types of Dongguan precision castings are also constantly changing. Dongguan precision castings have gradually become an important part of our daily life. Various types of door handles, door locks, small water pipes and other occasions can see the use of Dongguan precision castings.
Dongguan precision castings have excellent mechanical and physical functions. They can have a variety of different strength, hardness, and resistance coordination functions. They can also have one or more special functions, such as wear resistance, high temperature and low temperature, Corrosion resistance, etc.
Dongguan precision castings have a wide range of weights and dimensions. The lightest weight is only a few grams, the heaviest can reach 400 tons, the thinnest wall thickness is only 0.5 mm, the thickest can exceed 1 meter, and the length can be from a few millimeters to ten. A few meters can meet the application requirements of different industrial sectors.
Compare the difference between Dongguan precision castings and stainless steel forgings:
1. Dongguan precision castings have outstanding wear resistance and shock absorption function. Because graphite in cast iron is beneficial to smoothness and oil storage, it has good wear resistance. The same, because of the presence of graphite, gray cast iron has better shock absorption properties than steel .
2. Dongguan precision castings have good technical functions. Because gray cast iron has high carbon content and is close to eutectic composition, it has low melting point contrast, excellent fluidity, and small shortening rate. Therefore, it is suitable for casting complex or thin-walled Dongguan precision castings. In addition, because graphite makes it easy to form chip breaking during cutting, the machinability of gray cast iron is better than that of steel.
3. After the stainless steel is processed by casting, its arrangement structure and mechanical function can be improved. After the casting method is hot-worked and deformed, due to the deformation and recrystallization of the stainless steel, the original coarse dendrites and columnar grains become the equiaxed recrystallization arrangement with finer grains and uniform size, so that the original segregation in the steel ingot, The compaction and welding of looseness, pores, slag inclusions, etc., the arrangement becomes more tight, and the plasticity and mechanical functions of the metal are improved.
4. The mechanical function of Dongguan precision castings is lower than that of forgings of the same raw material. However, the casting process can ensure the continuity of the metal fiber arrangement, keep the fiber arrangement of the forgings consistent with the shape of the forgings, and ensure that the parts have outstanding mechanical functions and long service life. Use fine die forging, cold kneading, warm kneading and other technologies The forgings produced are unmatched by Dongguan Precision Casting.
Whether it is Dongguan precision castings or stainless steel forgings, they are an important part of mechanical production. In mechanical production, according to the different functions of the product, choose the corresponding Dongguan precision castings or forgings, as long as you give full play to the effects of Dongguan precision castings or forgings. , Talent has the perfect mechanical product.
