Technology

 

  •          Our technology satisfies the following requirements:
    • subsequent mechanical treatment costs reduction;
    • stable quality and precision of casting;
    • production costs reduction;
    • environmental stress reduction.

             Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to lost-wax casting with the exception of the usage of foam for the pattern instead of wax. This process takes advantage of the low boiling point of foam to simplify the lost-wax casting process by removing the need to melt the wax out of the mold.

             Patterns are made using:
    • die casting;
    • expanded polystyrene modelling (time-saving method).

             This technology is universal and used for small-scale and single-piece manufacturing high-quality casts of frequently changing models.

  • Info.

    LFC method is widely used in the United States, Japan and European counties. More than 30% of casting products on developed markets is made using the LFC method.

             Technology advantages:

    • availability of thin wall steel casts production;
    • excellent precision (full compliance of LFC casts with cold hardening prototypes);
    • up to 50% reduction of allowances for machining, as consequence, lowering of work content of the subsequent machining;
    • more than 50% reduction of cleaning and chop procedures;
    • cost and time saving maximizes when small-scale and single-piece manufacturing is needed;
    • eco-friendly production due to implication of small-sized and universal isolation of pollutant systems.
