Decorative and technical casting for patterns from foam. Casters make artistic casting of cast iron, steel, aluminum, copper alloys, executes orders for serial and single details. Benches, lights cast, casting bars, grilles, fences and technical metal casting. Liem artistic and technical cast, take the order on cast iron grates, fences, bas-reliefs, gates, gates, bollards, lights, benches, plates, dumbbells, kettlebells. Tooling and one-time pattern is cut from expanded polystyrene on the 3D-Fraser, manufacture of molds for plastic foam patterns often perform accurate casting.
Examples, which may be cast product to the customer, or make original casting.

A cut pattern of foam on CNC machines and 3D Fraser, and such models can be produced most of the castings, shown above
In the manufacture of patterns with the help of CNC machine tools for cutting foam three-dimensional model of complex parts is broken down into simple elements that are cut on the machine. Then glue them receive large size pattern with a rather complex form (the body of large motors, pumps, gearboxes, frame). So getting a pattern casting in small batch and unit production when manufacturing the mold another method uneconomical. In this technique molten metal is poured directly into the pattern and replaces it into the moldable mixture.
Stages of production.
To build bulk three-dimensional model of the items in the CAD-system (SolidWorks, Kompas 3D, CATIA, Autodesk Inventor, etc.). The volume model is broken down into simpler pieces that are technologically possible to cut on the machine, shape cutting foam. The contours of the fragments are assembled in the size of foam preform and preparing the files of control programs. Cutting on CNC and manual refinement of the details, if necessary. The compound fragments in the pattern.
