Coatings for Sand Molds and Cores

Coatings for Sand Molds and Cores

The high casting temperatures associated with steel foundries requires careful selection of refractory materials, to ensure full protection against metal penetration and burn-on defects.
The range of coatings utilise high purity zirconium silicate or metal oxide refractories to offer protection under the most extreme casting conditions.

A full range of specialist products is also available to cover specific applications, such as the high demands of manganese steel, highly alloyed stainless steels or metal penetration due to hot spots or high metallostatic pressures.

"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%."

“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.”
