Produce various casting in all kind of carbon steel, low alloy steel & stainless steel as per client’s request.
Advantage of investment casting is also known as the lost wax process.
. Parts made with investment castings often do not require any further machining, because of the close tolerances that can be achieved, and with fine finish. Therefore can save lot of expenses of Material and Machining.
. Intricate shapes can be made with high accuracy. In addition, metals that are hard to machine or fabricate are good candidates for this process. It can be used to make parts that cannot be produced by normal manufacturing techniques, such as turbine blades that have complex shapes, or airplane parts that have to withstand high temperatures, save the expenses of welding and assembling.
. Can cast complicated and elegant characters and pattern on the surface, show & promote your company’s image greatly
.With high productive rate, good duplication, low tooling cost, is good for big or small batch.
