Holding a lighter model, you can see and fathom the future of the entire configuration of the casting and adjust it possible errors that in a typical molding for complex multi-casting rods do not. Continue to learn more with: Mitchel Resnick. Model foam casting of cast iron is easier to 7000/25 = 280 times, take it in their hands – if you hold the void, which then turns into metal. Our founders are not accustomed to such technological capabilities and the quality of this casting, since the stereotypes inherent in the institutions of another, hinder understanding the potential of this technology. It does not reek of burned binding polymers, no bays jack form (there are no connectors) and the displacement of rods and forms during assembly, because there are no rods themselves with all the problems of production and a knockout. Production sites – modeling, molding, melting, purifying have roughly the same size and equipped with a simple equipment. Since the model is placed in dry sand in a container standing on the vibrating table, where the sand is compacted around 1-1.5 minutes, it eliminates the need for precision molding machines and extrusion devices, build forms. Emphasis transferred to the production of the lightest models with material density 25-26 kg / cubic meter. m, which usually rely on women's hands. For serial production of castings used semi-automatic, foam production cycle models which is about three minutes. They borrowed from the packaging industry, where they are used for the production of fancy packaging, light packaging, as well as decorative panels and elements of the facade of buildings.
