Degassing Equipment (MDU) and Metal Treatment Station (MTS)

Degassing Equipment (MDU) and Metal Treatment Station (MTS)

Metal Treatment Station (MTS) one-step automated treatment system.

By using the MTS System (Metal Treatment Station) aluminum melts can be completely and automatically treated in one step. While degassing with the proven FDU technology, all required treatment agents can be added at pre-set levels.


A full range of fluxes branded COVERAL MTS has been specifically formulated for use with the MTS 1500 unit. This range includes cleaning/drossing, sodium modifying, grain refining and gassing. The latest development in the range is an agent for removing alkali and earth alkali elements from molten aluminum, helping foundries to replace chlorine treatments.


The Metal Treatment Station provides:


Metallurgical benefits:
• consistent mechanical properties
• improved metal cleanliness
• reproducible results


Operational benefits:
• fewer emissions
• reduced temperature loss
• minimum operator involvement


Economic benefits:
• reduced consumables requirement
• minimized aluminum loss
• low labor requirement


MTS 1500 technology is available for most of the MDU designs; the machine can be equipped with either one or two hoppers for treatment products.


MDU Rotary Degassing Equipment


MDU degassing units are an automated metal treatment system for the environmentally-friendly degassing and cleaning of aluminum and copper alloys.


MDU units use the impeller principle with a patented rotor which creates fine inert gas bubbles and mixes them with the melt. These fine bubbles are distributed homogenously throughout the melt without disturbing the surface, maximizing the contact area between the inert gas and the melt. The effectiveness of the Foseco MDU means that higher levels of degassing and cleaning can be achieved and treatment times can be reduced.


A range of sizes and designs of machines are available to suit the needs of the individual foundry.


• lower hydrogen levels
• reproducible results
• efficient melt cleaning
• improved casting surface finish
• reduction of hard inclusions in castings
• reduced machining costs
• increased tensile strength of castings
• weldable pressure castings
• environmentally friendly process
• better elongation

"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.”
