Modern diecasting faces critical procedural issues \u2013 such as the\u00a0reduction of the refuse caused by porosity<\/b>. \nPorosity can have different root causes, such as air incorporated during the injection process.<\/p>\n\n

Internal porosity<\/strong> can have dimensions ranging from a few microns to a few millimeters, causing subsequent poor surface quality<\/strong> that can be seen during the extraction and even after thermal surface treatments.<\/p>\n\n

The presence of air also creates a\u00a0counter-pressure generated in the filling phase, which can cause\u00a0cold joints or incomplete fillings<\/strong><\/b>.<\/strong><\/p>\n\n

A solution to these problems is given by our\u00a0Fondvacuum\u00ae\ufe0f<\/sup>\u00a0HY-VENT (Hybrid venting).<\/strong><\/p>\n\n

The Fondvacuum\u00ae\ufe0f<\/sup>\u00a0HY-VENT (Hybrid venting)<\/b>\u00a0valve combines the capability of air evacuation<\/strong> systems of normal valves with the efficiency of the active vacuum<\/strong> obtained from the Fondvacuum\u00ae\ufe0f<\/sup>\u00a0suctioning units.<\/p>\n\n

Thanks to their innovative design,\u00a0Fondvacuum\u00ae\ufe0f<\/sup>\u00a0HY-VENT <\/b>valves are able to guarantee a high performance <\/b>in air evacuation <\/b>from molds and a fast aluminum solidification. <\/b>Furthermore, <\/b>Fondvacuum\u00ae<\/sup>\u00a0HY-VENT valves are able to endure intensive usage at high temperatures thus, allowing for long periods of time without maintenance<\/strong>.<\/p>\n\n
