An integrated sand regeneration system effectively addresses this issue: mechanical regeneration removes scale, while thermal regeneration burns off the binder. Combined with screening to control particle size and a <a href=\"https:\/\/chinametalfoundry.com\/cs\/blog\/mastering-sand-casting-mold-materials\/\" target=\"_blank\" rel=\"noopener\"  data-wpil-monitor-id=\"5479\">sand cooler to stabilize the mold<\/a> cavity temperature, this system enhances mold cavity integrity. A cleaner sand-binder mixture allows the molten copper to flow more smoothly during pouring.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6b65b8f elementor-widget elementor-widget-elementskit-heading\" data-id=\"6b65b8f\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"elementskit-heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"ekit-wid-con\" ><div class=\"ekit-heading elementskit-section-title-wraper text_left   ekit_heading_tablet-   ekit_heading_mobile-\"><h3 class=\"ekit-heading--title elementskit-section-title\">Nasazen\u00ed CNC obr\u00e1b\u011bc\u00edch center se za\u0159\u00edzen\u00edm na v\u00fdrobu jader<\/h3><div class=\"ekit_heading_separetor_wraper ekit_heading_elementskit-border-divider ekit-dotted\"><div class=\"elementskit-border-divider ekit-dotted\"><\/div><\/div><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d949c57 elementor-widget elementor-widget-text-editor\" data-id=\"d949c57\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Nesouosost j\u00e1dra m\u016f\u017ee zp\u016fsobit <a href=\"https:\/\/chinametalfoundry.com\/cs\/blog\/3d-printed-metal-casting\/\" target=\"_blank\" rel=\"noopener\"  data-wpil-monitor-id=\"1889\">rozst\u0159ik kovu a zintenzivn\u011bn\u00ed oxida\u010dn\u00edch reakc\u00ed p\u0159i odl\u00e9v\u00e1n\u00ed m\u011bdi<\/a>.
