Centrifugal filter units
HOLLOTEX CFU products are highly engineered filtration devices used exclusively in the production of large ferrous castings. The device comprises of a HOLLOTEX Refractory Centrifuge System and STELEX Ceramic Foam Filters.
The HOLLOTEX refractory centrifuge system separates inclusions from the molten metal before it reaches the filters. The integral STELEX ZR filters remove remaining contaminants from liquid metal and reduce turbulence as the mould cavity fills.
HOLLOTEX Shroud
HOLLOTEX Shroud provides a reliable method of shrouding the metal stream as it exits the bottom pour ladle eliminating air entrainment in the sprue, and the subsequent formation of re-oxidation inclusions. The molten metal is therefore cleaner, allowing a higher level of filtration efficiency and turbulence reduction in the production of large steel castings.
"Prior to our relationship with Weaver Materiel, we were purchasing riser sleeves direct from the OEM. As a stocking distributor, Weaver typically is able to deliver same or next day. OEM lead times averaged three to four weeks. With Weaver, I've been able to reduce my working inventory by about 40%."
