Thermo-regulated injection systems<\/strong> (Cold Runner Block – CRB) are by now largely used to mold a wide variety of products.<\/h2>\n

Its main function is to maintain the compound temperature at a controlled<\/strong> level before injecting it near or inside the mold cavity. This offers outstanding benefits such as reduction of raw material waste<\/strong> by reducing the runners,cut-down of cycle times <\/b>with major increase of productivity, no more compound burns. <\/b>All this while maintaining the quality of the moulded product.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row fullwidth=”true” fullwidth_content=”false” css=”.vc_custom_1548691870346{padding-top: 80px !important;padding-bottom: 80px !important;background-color: #e8f5fb !important;}” id=”termoregolatistandard”][vc_column][vc_column_text css=”.vc_custom_1551799526807{margin-bottom: 40px !important;}”]\n

    \n
  • Sturdy machined steel blocks including runners to distribute the raw material and cooling fluid circuits;<\/li>\n
  • Free-flow nozzles or stopper nozzles. Stoppers can be activated hydraulically or pneumatically.<\/li>\n
  • The removable plate enables to replace the compound and the user can verify the cleaning status visually, thus reducing risk of pollution by other compounds.<\/li>\n
  • Specific thermo-regulation circuits developed inside the nozzles cover most of the surface of the rubber distribution circuits, created with soft bends to reduce the stress on the compound.<\/li>\n<\/ul>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”2\/3″][vc_column_text css=”.vc_custom_1744962838752{margin-bottom: 0px !important;}”]\n

    WHY TO CHOOSE A COLD RUNNER BLOCK<\/h2>\n

    Rubber moulding companies value the strategic role played by thermo-regulated blocks (CRBs) to enhance production cycles while reducing waste material.<\/p>\n

    Using a CRB means adopting an injection system able to keep the compound at pre-vulcanization temperature before injecting it near or into the mold.<\/p>\n

    This is made possible thanks to:<\/p>\n

      \n
    • insulation from the heat source;<\/li>\n
    • a controlled cooling system.<\/li>\n<\/ul>\n

      BENEFITS<\/h3>\n
        \n
      • Better handling of difficult, highly accelerated compounds.<\/li>\n
      • Reduced risk of burning the compound.<\/li>\n
      • It is possible to inject the compound in several points of the mold.<\/li>\n
      • It is possible to use multiple-cavity molds.<\/li>\n
      • Reduction of non-conformities.<\/li>\n
      • Homogeneity and repeatability of molded items.<\/li>\n<\/ul>\n

        CRBs help you meet the needs of those major customers in the rubber industry who are no longer satisfied with the cheapest-cost-perpiece policy and who are now looking for:<\/p>\n

          \n
        • Manufacturers able to solve customers\u2019 problems by anticipating needs and opportunities.<\/li>\n
        • Technical items and gaskets with increasingly higher performance to comply with the most demanding regulations.<\/li>\n
        • Reliable production timing.<\/li>\n<\/ul>\n[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”5538″ img_size=”full” alignment=”center” css=”.vc_custom_1740075147659{border-bottom-width: 3px !important;border-bottom-color: #1a9dd8 !important;border-bottom-style: solid !important;}”][vc_single_image image=”5533″ img_size=”full” alignment=”center” css=”.vc_custom_1740075157970{border-bottom-width: 3px !important;border-bottom-color: #1a9dd8 !important;border-bottom-style: solid !important;}”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row fullwidth=”true” fullwidth_content=”false” css=”.vc_custom_1544974753215{padding-top: 80px !important;padding-bottom: 80px !important;background-color: #0a3e56 !important;}”][vc_column][mk_custom_sidebar sidebar=”sidebar-1″][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
