These processes, in the descending order of the number of aluminum castings, are: die casting, permanent mold casting, sand casting, gypsum casting, investment casting and continuous casting.The casting process is selected according to factors such as cost, feasibility and quality.Feasibility is not a problem because the above methods are feasible.
However, the most appropriate casting method can be determined based on the design features or dimensions.For instance-Large products are manufactured using sand casting.Quality factors are also important when choosing casting processes.
Quality refers to mechanical properties (scalability and strength) and soundness (surface defects, cracking, and free air holes ).The most commonly used methods can be described as follows: Die Casting: about $2 depending on the statistics.Death value 5 mAluminum alloy castings are produced in the United States alone every year.
The die casting process uses twice the tonnage of aluminum alloy as a combination of other casting processes.Die Casting is best suited for mass production of relatively small parts.If cast-, aluminum die casting with a weight of up to 50 kg can be producedThe high cost of machines and tools is reasonable.
Some common applications of die-casting aluminum alloy include alloy 380.A380 alloy mower shell 0.For street lamp housing, dental equipment, typewriter frame, 360 alloy.For frying pan, cases box, cover plate, parts that need corrosion resistance, alloy 413.
0 for the outside parts of the motor, such as the connecting rod, piston, housing and alloy 518.1 for conveying parts, escalator parts, aircraft, marine hardware.Die casting is not easy to heat or weld due to gas accumulation.
In order to overcome this obstacle, the war is going on.Aluminum Alloy Die castings are generally produced in aluminumsilicon-copper alloys.This alloy series offers an excellent combination of corrosion resistance, strength and cost, as well as breathing opportunities that are essential for easy casting for short heat periods and high fluidity.
If a person wants better corrosion resistance, he should use alloys with lower copper content.Permanent mold casting: permanent mold casting is the most suitable for high mold castingMass production.They are larger in size than die casting.The pouring rate of these castings is very low.
They\'re gravity.
fed.
Permanent mold castings demonstrate excellent mechanical performance.If heat treatment is carried out, there is still a lot of room for improvement.Some of the most common aluminum mold casting alloys include 366 alloys.
Alloy 355 for automobile pistons.
0, A357.
0, C355.
0 is used for impeller, timing gear, compressor, missile and aircraft components, alloy, and.0, 356.0 for aircraft wheels, machine tool parts, pump parts, valve body, marine hardware and 296.0,333.0, 319.0.Sand casting: this type of casting involves the formation of casting molds (with sand.
It includes conservative sand casting and lossfoam casting.The first involves forming a pattern of sand, pouring the melted metal into it, and crushing the product after it is formed.Lost-The foam pattern includes the placement of dispensable polystyrene patterns in the mold.
The rest of the procedure is the same as the conservative sand casting
