Description
These Lost Wax Precision Casting Parts are made of 420 stainless steel. 420 stainless steel is a martensitic stainless steel, which has a certain degree of wear resistance and corrosion resistance, and has a high hardness. Its price is a lower class of stainless steel balls, and it is suitable for working environments where there is no high requirements for stainless steel. 420 stainless steel is suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, instruments, transportation tools, household appliances, etc. It is mainly used to manufacture parts resistant to atmospheric, steam, water and oxidizing acid corrosion.
Fabrication method
These Lost Wax Precision Casting Parts are made by wax loss method. This method does not need to open the mold when making the mold, so the shape of the casting is rarely limited by the process. The biggest feature of this method is to use low melting point materials as "molds", simplifying the mold making process. This method can make the finished product complete without welding. This method can directly cast very precise parts, without machining the parts. Compared with conventional turnover casting, it is more suitable for casting devices with complex shapes.
