Investment Casting Parts

Investment casting is a kind of casting process. Some people call it "lost wax casting" or "precision casting". It can also be said to be a special casting improved from ordinary casting. Its precision and surface finish are higher than Ordinary casting is much higher. In some places where the precision requirements are not very high, investment castings can be used and assembled directly. Even in some positions that require precise assembly, we can meet the required requirements through local secondary CNC machining of the product, which can reduce the product's cost. Below are some of the investment castings we have done.
