Casting consists of several stages. The first is to pour a liquid material into a mould contains a hollow cavity of the desired shape. The second is to allow that liquid material to cool and solidify. Lastly, this solidified part is ejected or broken out of the mould to complete the process.
Casting materials are usually metals. Also quite common are cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster, and clay.
Modern casting processes are categorized by expandability/reusability of mould, mould material, pouring method, etc….Some of those casting methods those are available in our factories are: Sand casting; Investment casting; Die casting;

Sand casting is the most used method of metal casting. The process is characterized by using sand as the mould material. Sand casting is used to make iron, steel, bronze, brass parts of medium to large size with a smooth surface and accurate dimension.
Our factory is capable of doing a sand casting with various sizes at a maximum capacity of 50 tons/month.

Investment casting or often referred to as wax casting derives its name from the pattern being invested (surrounded) with a refractory material (or Wax). Investment casting is especially used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.
Compared to sand casting, the sheer volume of parts/components that can be produced is smaller. But the end product cast component comes with a much better surface finish, porosity, and dimensional accuracy. And often require very minimum post-process machining.
Our investment casting facility is capable of doing 30 tons/month and expanding.
Together with our in-house heat treatment, surface treatment, state-of-the-art metrology, and nondestructive test equipment (NDT), our engineers have experience of doing metal casting applications that spread over almost every industrial sector: Automobile; Aerospace; Oil and Gas; Railways; Shipping; Heavy equipment; Machine tools; Plant machinery; Defense; Electrical equipment; Plumbing industry; Household appliances; Furniture; Art.. etc
