Investment casting is suitable for making intricate shapes. 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. DK use advanced software to make 2D and 3D technical design, and also process design. Investment casting is often used for making part less than 50KGS, while lost wax casting can make parts until 200KGS. The products are normally used in auto and motorcycle industry, train brake, machinery industry, and electric machinery industry, machinery, driving medium, construction and hardware.
