What is lost wax casting

Lost wax casting  is now known as investment casting, is a precision casting process with less cutting or no cutting, is an excellent technology in the precision casting industry, its application is very extensive. 

 Choose suitable mold material (such as wax) to manufacture investment mold;  Repeat the process of dip refractory coating and sprinkle refractory sand on the investment mold, harden the shell and dry it;  Then melt the internal mould to get the cavity;  The shell is roasted to obtain sufficient strength, and the residual investment material is burned off.  Metal materials needed for pouring;  After solidification and cooling, sand cleaning, high precision products can be obtained.  Heat treatment and cold working and surface treatment as required.  

The lost wax casting process is a refined technique for the casting of alloy materials.  Mold making, the first step in the process, involves the use of waxes to create patterns that are “invested” with refractory materials.  The alloy is then poured into a cavity (mold) in the refractory material in order to produce a duplicate of the pattern as the desired part.  This age-old industrial process has the power and reliability to provide tolerances within thousands of an inch. 

The modernization of lost wax casting techniques within foundries has been perfected over decades of modern industrialization.  Pricing varies per metal and market prices, but investment casting delivers the best cost-per-part scenario over other options.
