EXOPOURS (direct pouring sleeves and filters)

Exopours are an assembly of a vacuum formed sleeve and a foam filter that is inserted into the sleeve.  This assembly combines to provide the foundry with a pouring cup to pour metal into, a filter to provide non-turbulent metal flow to the casting while trapping oxides, dross and other non-metallics and a riser sleeve to provide feed metal to the solidifying casting.

Exopours can be used to replace many conventional gating systems which will reduce costs associated with gating removal in your facility.  We also can offer these with an oil sand breaker core attached to the bottom of the Exopours to further reduce contact area.

Exopour sleeves can be made in insulating or exothermic materials.  We offer silicon carbide filters for grey iron and ductile iron castings and zirconia filters for steel castings.  Exopour sleeve sizes are designated by the filter size 2" diameter through 9" diameter and sleeves and filters can be ordered and shipped separately or assembled.
