Casting very versatile, has been applied to the metal and the whole machinery and electronics industries, and its use is a growing trend. Concrete pier used trash rack supply, construction, hardware, equipment, construction machinery and other large machinery, machine tools, marine terminals trash rack manufacturers, aerospace dock trash rack price, automobiles, motorcycles, electronics, computers, appliances, lighting and other industry, many of which are ordinary people all day contact, but do not know the metal objects. Casting a variety of classification methods: by its use of different metal materials into steel, cast iron, bronze pieces, cast aluminum, cast magnesium parts, pieces of cast zinc, cast titanium parts. And each class can be divided according to their chemical composition or casting microstructure further divided into different categories. Such as cast iron can be divided into gray iron castings, ductile iron castings, vermicular cast iron, malleable iron, alloy cast iron pieces; according to different methods for molding, casting can be divided into ordinary sand casting, metal casting, die casting centrifugal casting, continuous casting parts, castings, ceramic castings, castings ESR, bi-metal castings. Among the most common application of sand casting, casting about 80% of the total production. The aluminum, magnesium, zinc and other nonferrous castings, mostly casting. For the requirements of the more important problems or prone to casting the casting process, but also the need for non-destructive testing work can be used for non-destructive testing techniques to detect quality ductile iron castings, including liquid penetrant testing, magnetic particle testing, eddy current testing, radiographic testing, ultrasonic testing and vibration detection. Mold tilt display and alloying, have benefited. Eliminate shrinkage defects casting machine is a complex understanding of the implementation process. Should be "thermal equilibrium" as the basic principles of scientific analysis Ju body casting done, establish a reasonable process plan, move good selection of suitable modeling material, tooling and correct operation and standardization. Then any machine casting shrinkage defects can be resolved. Dock trash rack supply, Chen Hua machinery (certified), dock trash rack is provided by China Machinery Co., Ltd. Qingdao Chen.
