ARE THESE METHODS RISKY?<\/span><\/b>\u00a0<\/span><\/h3>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1570816403952{margin-bottom: 0px !important;}”]Sandblasting is an effective method but<\/span>, extensive<\/span> use can ruin <\/span>both <\/span>the chrome plating layer <\/span>as well as<\/span> the <\/span>cavities <\/span>edges <\/span>of the mould<\/span>.<\/span>\u00a0<\/span>The harder the grit used, the more incisive the sandblasting on the hard surfaces will be. <\/span>To minimize or even eliminate this “side effect” and <\/span>to <\/span>preserve <\/span>better <\/span>the surface of the mould it is better to choose a less aggressive aggregate, such as plastic or bicarbonate.<\/span>\u00a0<\/span><\/p>\n

If<\/span>, <\/span>instead<\/span>,<\/span> you prefer to use the sandblasting method with glass micro-granules<\/span> we<\/span> suggest you <\/span>to <\/span>follow<\/span> the<\/span>se <\/span>parameter<\/span>:<\/span>\u00a0<\/span><\/p>\n

    \n
  • Use sand granules in size 40\/70 (very fine)<\/span> with\u00a0<\/span> air<\/span> pressure not be greater than \u00be bar.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

    Determining factors for an excellent result are the air pressure and the distance of the <\/span>pistol<\/span> from the nozzle.<\/span>\u00a0<\/span>[\/vc_column_text][vc_column_text css=”.vc_custom_1570627863629{margin-bottom: 0px !important;}”]\n

    IS THERE A SIMILAR METHOD BUT LESS AGGRESSIVE?<\/span><\/b>\u00a0<\/span><\/h3>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1570716987144{margin-bottom: 0px !important;}”]Yes! <\/span>The best<\/span> alternative is the cryogenic cleaning<\/strong>.<\/span>\u00a0<\/span>This type of cleaning, also known as “dry ice cleaning<\/strong>“, uses dry ice pellets and compressed air. This <\/span>mixture<\/span>m<\/span> hitting the surface to be cleaned<\/span>,<\/span> brings to<\/span> detachment of the incrustations and cleaning of the fumes.<\/span>\u00a0<\/span>The ice pellets are accelerated up to 300 m \/ s and come out on the surface with a special <\/span>pistol<\/span> at a temperature of -79 \u00b0 C.<\/span>\u00a0<\/span>[\/vc_column_text][vc_column_text css=”.vc_custom_1570627905262{margin-bottom: 0px !important;}”]\n

    WHY <\/span><\/b>TO <\/span><\/b>CHOOSE THE DRY ICE<\/span><\/b>\u00a0<\/span><\/h3>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1570717019547{margin-bottom: 0px !important;}”]Dry ice cleaning makes it possible to work directly on the <\/span>injection <\/span>maching<\/span> without having to remove the mould and does not compromise the chrome plating treatment.<\/span>\u00a0<\/span><\/p>\n

    Moreover, compared to other methods, it is very <\/span>convenient<\/span> in terms of time<\/strong>. In fact, cleaning can be carried out quickly and effectively without having to dismantle the <\/span>mould<\/span>.<\/span>\u00a0<\/span><\/p>\n

    These are the main methods for surface cleaning of the <\/span>moulds<\/span>, perfect if you produce technical articles in rubber.
