As a result, high-intensity pressure waves and hydroflows are formed and propagated in the liquid, which act on the casting body and the core mixture, causing the destruction and removal of the latter.<\/p>\n\n<h3>Advantages of technology<\/h3>\n<ul>\n    <li>Significant increase in productivity (2\u20134 times)<\/li>\n    <li>Reducing cost and energy consumption while ensuring high quality of core punching from complex castings<\/li>\n    <li>Radical improvement of working conditions and environmental conditions at the knockout site<\/li>\n    <li>Mechanization of heavy manual labor<\/li>\n    <li>Elimination of conditions for the occurrence of occupational diseases (vibration disease, silicosis, etc.)<\/li>\n<\/ul>\n\n<h3>Technology efficiency<\/h3>\n<ul>\n    <li>Removal of core and molding compounds of almost any strength<\/li>\n    <li>Elimination of additional casting cleaning operations<\/li>\n    <li>Reducing residual stresses in castings without heat treatment<\/li>\n    <li>Stabilization of geometric dimensions of castings<\/li>\n    <li>Reduction of production area by 2\u20132.5 times<\/li>\n<\/ul>\n\n<h3>Implementation<\/h3>\n<p>The technology has been implemented at enterprises in Ukraine and Russia, and has also been exported to Japan, Germany, Sweden, Spain, Hungary, Romania, India, Bulgaria, Slovakia, and Cuba.<\/p>\n\n<p><strong>Contact:<\/strong> <a href=\"tel:+380512558252\">+38 (0512) 55-82-52<\/a><\/p>\n<p><a href=\"\/en\/tekhnolohiyi\/\">\u2190 Back to list of
