But also we are one of the most professional supplier in our country. Garden decoration casting design is very fashion and popular. Because our products are of good quality and excellent price, they have won unanimous praise from people inside and outside the industry.
It refers to the equipment and devices of pure aluminum or aluminum alloy obtained by casting. Generally, the aluminum or aluminum alloy heated as liquid is poured into the mold cavity by sand mold or metal mold, and the aluminum parts or aluminum alloy parts of various shapes and sizes are usually called aluminum die casting. The density of cast aluminum alloy is smaller than that of cast iron and cast steel, but the specific strength is higher. Therefore, aluminum alloy castings can reduce the weight of the structure under the same load. Therefore, aluminum alloy castings are widely used in the aviation industry, power machinery and transportation machinery manufacturing.
Aluminum alloy has good surface luster and good corrosion resistance in the atmosphere and fresh water, so it has a wide range of applications in the manufacture of civil utensils. Pure aluminum has good corrosion resistance in oxidizing acid medium such as nitric acid and acetic acid, so aluminum casting has certain application in chemical industry.
Pure aluminum and aluminum alloy have good thermal conductivity. The heat exchange device used in chemical production and the parts required to have good thermal conductivity in power machinery, such as cylinder head and piston of internal combustion engine, are also suitable for manufacturing with aluminum alloy. As the casting cools and solidifies faster in the metal mold than in the sand mold, and the metal mold has no tolerance, the casting stress generated in the casting is larger than that in the sand mold and has a greater tendency to crack, and it is also prone to defects such as insufficient pouring, cold insulation, white mouth for the casting.
Usually, The following structural problems should be paid attention to in preventing cracks in metal mold casting castings:the requirements for uniform wall thickness, moderate transition and connection between walls, and proper fillet at corners should be stricter than sand casting.Vertically connected walls should be replaced by obliquely connected walls ,protruding parts such as bosses, ribs and flanges that hinder the free shrinkage of castings shall be minimized.And when reinforcing ribs are arranged on the casting, the influence of the reinforcing ribs on the shrinkage of the casting should also be considered.
