The reason why aluminum castings are widely used in industry The physical properties of  aluminum Casting Foundry  refer to the specific gravity, melting point, thermal expansion, magnetism, electrical conductivity, thermal conductivity and other physical characteristics of the metal. The chemical properties of aluminum casting mainly refer to the chemical stability of metal or alloy, i.e. oxidation resistance and corrosion resistance. These properties are mostly related to alloy composition and microstructure. Specific gravity is the ratio of the weight of a body to the weight of water of the same volume. For example, the specific gravity of steel is about 7.8 g/cm. The proportion of metal materials is directly related to the weight of parts, especially in the aerospace manufacturing industry and the design and manufacturing of missiles, space navigation, man-made satellites, etc., the weight of  Aluminum Casting design  is very important. In many precision machinery, some hig

Special processing technology of aluminum castings has been developed Aluminum casting  is widely used in non-ferrous metal die casting, casting, aluminum profile, automotive parts, machinery manufacturing, hardware, pump valve industry surface treatment. Mainly concentrated in the product surface oxide, edge surface burr, surface roughness, matte fruit, leveling and strengthening, derusting treatment. Stainless steel shot commonly known as stainless steel wire cut shot, using wire drawing, cutting, throwing round and other processes refined from the appearance of bright rustless, round like beads. Special high-precision copper strip alien: transistor type frame with high precision copper strip, generally for phosphorus and silver alloy with high strength and high conductivity, the cross section is made up of thick and thin while edge is 1.27 mm thick, thin edge is 0.38 mm, the bandwidth of 68 mm, length is more than 200 meters, the production method three kinds, namely the chi

The five major defects of  aluminum alloy die castings : Cold. Crack. Shrinkage. Gas. Degassing is aluminum alloy die casting five major defects for short: One: cold: refers to the casting surface rough rough. Cold lines. Water content, etc. Two: crack: refers to the adhesive mold pull crack. Top crack. Mold temperature too low cold crack. Shrinkage crack. Three: shrinkage: refers to the uneven surface of the casting sag. Gas: means that there are air holes at the inlet of the  Cast Aluminum Garden Decoration . There are air holes at the overflow slag package mouth. There are air bubbles on the surface of the casting. There are air holes inside the casting. Five: take off: is to point to the casting surface to have a layer like purple similar thin take off we call him peel. There are thick and thin surface very small and few. Some thin off the other side and casting body we call him septum. Remove the five major defects: 1. Understand casting process and find out th

What are the methods to extend the life of cast iron fence? Today I would like to tell you about the  Garden Decoration Iron Casting  fence  to extend the life of products: Because most fences are used outdoors, they need to be maintained, maintained and inspected after a period of exposure to the sun and wind. The following are specific methods: 1, avoid knock against:  Garden Fence Casting Foundry  in considering the effect of the outdoor environment design enclosures, so in the selection of anticorrosion and wear-resisting coating requirements, but in the use of or to pay attention to during the process of handling light to take light put, put, wrought iron products, should also keep flat on the ground, when installation should guarantee its strong, if shaking instability, long, wrought iron guardrail causes deformation, affect the service life of the fence. 2, eliminate rust: if the iron fence rust, do not self-assertion with sandpaper grinding. Rust is smaller and more
