Omnidex Mining works with highly skilled Lost Foam Casting experts to create exceptional Lost Foam Casting products. We take extreme care at the pouring stage to ensure the right amount of molten metal is poured into the mold and the right level of cooling is reached before the mould is broken.
Patterns made from low-strength materials such as foam can easily be damaged and distorted. It is best to have Lost Foam Casting specialists (such as Omnidex Mining) to carry out this type of casting. Low quality standards and the lack of care at this stage could result in ruined castings and incur very high losses (both the mold and the pattern will have to be replaced).
We make sure every step is done in the proper way. Material specifications, dimensions and tolerances are closely monitored and maintained throughout the process and we utilizes computerized simulation to help keep production costs and waste down.

Lost Foam Casting is a straightforward process that offers more freedom of design with less manufacturing steps, which makes it a popular casting solution for many products.
This casting process is generally more expensive than other casting processes, but offers a lot of advantages. It can deliver more complex castings in one-piece (no draft required, no need to use cores), reduce the weight of casting parts and minimise further machining and cleaning. The as-cast finish is usually of a very high standard without any split lines and no flash is formed.
Lost Foam Casting shares many of the advantages with lost wax investment casting, but it is generally more economical than the later. Lost Foam Casting involves fewer steps and uses cheaper materials (compare to wax). Foam are also easier to handle (can be glued and carved), which further aided in the freedom of design.
All these features helps keep waste levels down and minimise per-unit production costs, which makes Lost Foam Casting ideal for single parts, small volume production or particularly complex and large parts (from 0.5kg up to 10 tons).
Here is a summary of its pros and cons:
Lost Foam Casting can be used with all types of ferrous and non-ferrous materials, including aluminium alloys, nickel alloys, steels and cast irons. The process can also be used with copper alloys and stainless steels.
