Pros of Lost Foam Process

When it comes to moulding processes, most people think of investment casting. However, the lost foam process is a more convenient way to create objects from the mould without facing any inconvenience. Polystyrene pellets are put inside the mould cavity, into which molten metal is poured after that. This results in the expansion of the polystyrene pellets, which then takes the form of solid casting. The lost foam process is unique. No other casting process allows this much flexibility for designs. At GPI, there have been some changes in recent years in terms of the lost foam process. Not only has there been an alteration in the raw materials but also one can notice the improvements of equipment as well. It can be fairly said that GPI has made the lost foam process way easier to conduct.

There are several advantages of resorting to the lost foam process. Binders, additives and cores are not needed for the casting. Moreover, manpower is considerably reduced and this proves to be a boon for many industries. The lost foam process is environment-friendly and comes with quite flexibility in casting designs. One would also notice the minimum involvement of scrap volumes. While other casting processes require several steps to reach the result, this process is relatively easier and is straightforward. Another noticeable advantage of using this process is that it creates castings with an accuracy of high dimensions.

GPI uses the lost foam process for reduced cost and to achieve a high level of freedom to create any design. The lost form process is a perfect match for cast products like that of cylinder blocks, valves, fire hydrants and many more.
