Stainless Steel Investment Casting

 The mechanical properties of Stainless Steel Investment Casting are relatively high during its use. The main reason is that the melting point of its products is relatively high. The Stainless Steel Precision Casting is easy to oxidize.The molten steel of Cast in Stainless Steel has poor mobility and shrinks during operation, with shrinkage rate 10 to 14%. Stainless Steel Casting in order to effectively prevent the cast steel from producing defects such as insufficient casting, shrinkage holes, shrinkage, cold cracks, cracks, and sticky sand, it is necessary to adopt complex technological measures than cast iron in the process of use.  In wax pattern process,we mix stearic acid and paraffin wax in wax pattern making,as you know,it is better than polyethylene,and the wax deformation is small.     In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at  24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.  In shell hardening process,we use aluminium chloride to harden the shell.This can make the shell so hard that it can`t be distorted,at the same time the bug which the casting may have will be decreased.If there are letters or numbers in it,they will be much clearer.  In dewaxing process,about 95% of the castings suppliers
