More freedom in design for more complex castings

Advancement in casting technology means that we are no longer limited by the shortcomings of some of the more traditional casting methods. Lost foam casting is one of such examples which carries the merits of investment casting into a technology-based era. Through the use of special foam patterns, this process can achieve relatively higher precision and tolerance, eliminate defects such as parting lines or flash, and still cater for the complexity of modern casting parts.

Omnidex has been working with some of the best lost foam casting foundries to produce exceptional products over the years. We are very familiar with the challenges in this type of casting and we take extreme care in every step to ensure the best result.

High-tech lost foam casting

Our engineers have extensive experience in designing lost foam casting patterns, and we have an arsenal of technology, including computer simulations, specialized foam materials and automated machines. The foam pattern can be made with CNC machining or foam injection for higher precision.

Excellent lost foam casting craftsmanship

Lost foam casting is a delicate process. Patterns made from foam can easily be damaged or distorted, therefore all foam patterns and molds must be handled with care. In the pouring stage, the molten metal must reach temperatures of above 1000°F in order to fully ‘dissolve’ the foam pattern and produce a complete casting piece. We make sure only the right amount of molten metal is poured into the mold, and the casting is thoroughly cooled in a controlled environment before the mold can be broken.

Strengths of lost foam casting

Lost foam casting shares many of the advantages with lost wax investment casting, but involves fewer steps and uses cheaper materials, thus it is generally more economical than the later. Foam patterns are also easier to shape (can be glued and carved), which further aids the freedom of design. All these features help keep waste levels down and lower per-unit production cost. This process is ideal for high quality single casting, small volume production, prototyping, or supersized castings (from 0.5 kg up to 10 tons)
