This method is used especially for non-ferrous metals, take time for processing extends for several weeks for the processing of steel mold. Then up to productivity (5-50 pieces / hour for each template), up to the maximum weight of castings 9 kg and 0.1 kg Minimum about. Paint the steel blanks template acetylene soot before casting process so as to facilitate removal of the cast from the mold, and extend the life of the mold. The Standing templates for a limited period of life before wear. Worn-out templates require re-finishing or replacement. Showing parts cast in permanent molds usually 20% increase in tensile strength, and elongation at 30%, compared Bmspockat sandy template. These templates need only to regular paint. This method is used by foundries in the formation of iron alloy, aluminum, magnesium, and copper.
