Information
Sand casting production of precision castings,surface finish,the density of material and microstructure and mechanical properties are often poor,so when casting these performance requirements higher,other casting method should be used,such as casting,lost wax casting,die casting,low pressure casting,and so on,edited by the company to introduce the below:
I.Features and Advantages of precision casting:
Precision casting is also called investment casting.Compared with other casting methods and parts forming methods,investment casting has the following characteristics:
1.High casting dimension accuracy,fine surface roughness,casting dimension accuracy can reach 4-6,surface roughness up to 0.4--3.2 m,can greatly reduce the machining allowance of casting,and can realize the manufacturing allowance,reduce the production cost.
2.Castings that can be cast in complex shapes and are difficult to be machined by other methods.The outline size of the castings can be as small as a few millimeters to a thousand millimeters,with the thinnest wall thickness of 0.5mm and the smallest hole of 1.0mm or less.
3.Alloy materials are not limited:carbon steel,stainless steel,alloy steel,copper alloy,aluminum alloy,high-temperature alloy,titanium alloy,precious metal and other materials can be produced by precision casting.It is especially suitable for alloy materials that are difficult to forge,weld and cut.
4.High production flexibility and adaptability,which can be used for mass production,small batch production or even single piece production.
To sum up,precision casting has the advantages of small investment scale,large production capacity,low production cost,simple process of complex products and quick investment effect,so it is in a favorable position and has a bright future in the competition with other processes and production methods.
