Casting problem: precision casting can process minimum pore size and wall thicknessPrecision casting. What are the advantages and disadvantages of each method? O (a _ U) O thank you
2. can be cast complex shape, and difficult to use other methods of processing castings. Casting outline size is small to several millimeters large to thousands of millimeters, wall thickness of thinnest 0.5mm, minimum hole below 1.0mm3. alloy material is not restricted: such as carbon steel, stainless steel, alloy steel, copper alloy, Aluminum Alloy and high-temperature alloy, titanium alloy and precious metals and other materials are available. For casting, forging, welding and hard alloy cutting, it is especially suitable for precision casting production method.4. high flexibility and adaptability. It can be used in mass production as well as small batch or even single productionIn summary, precision casting has the advantages of small investment, large production capacity, low production cost, simple process of complex product, investment and quick. Thus in a favorable position in the process and mode of production and other competition in the bright future.
By casting casting wax, get the original wax. In a wax brush on the sand layers of high temperature resistant liquid. To get enough after the thickness of dry, warm, the wax melted away, and get the required cavity blank consistent. Cast iron in the cavity, after curing the shell off, you can get the precision manufacturing product!!!Characteristics and advantages of precision casting:Precision casting, also known as investment casting, compared with other casting methods and parts forming method, investment casting has the following characteristics:1. dimensional accuracy, surface roughness is fine, the casting dimension precision to 4 - 6, the surface roughness can reach 0.4 - 3.2 m, can greatly reduce the machining allowance of casting, and can realize the surplus manufacturing, reduce the production cost.
According to casting talent network understanding: precision casting its casting outline size is small to several millimeters large to thousands of millimeters, wall thickness of thinnest 0.5mm, minimum hole 1.0mm below.Precision casting is a casting method in comparison with the traditional casting process. It can obtain relatively accurate shape and higher casting accuracy. The more common approach is: first, make the required blank (can leave the margin is very small or no allowance) of the electrode, and then use the electrode corrosion pattern, specific, forming a cavity.
