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%."

- JD Schmidt, QA Manager, Ohio Ferrous Foundry

“Ashland Foundry & Machine Works and Weatherly Casting are grateful for the partnership in our working relationship with Weaver Materials.  Weaver has helped us maintain pricing and avoid increases in a volatile market.  Weaver has always kept us in supply of material when markets dictated shortages/allocation status.  If Weaver was not in our vendor pool daily production ability would have been negatively impacted.  Weaver is also technically able to review our foundry processes and make suggestions to either achieve a cost savings or process improvement.  I am looking forward to a continued collaboration between the Weaver team and my locations.”
