Features & Benefits

Increased Productivity

Signature Series products provide higher tensile strengths and greater uniformity than other shell sands, which leads to a long list of benefits:
• Reduced wall thickness
• Better heat transfer capabilities
• Reduced sand usage
• Shorter invest cycle times and cure times
• Higher melt points improve flowability and finish
• More uniform curing
• Better shakeout properties


Reduced Scrap
• Reduced lamination and peelback defects
• Greater core strength for reduced breakage
• Lower Loss On Ignition for fewer gas defects


Reduced Hazardous Air Pollutants and Smoke
• The first resin-coated sand product specifically designed to reduce free phenol emissions
• Neozien Technology additive eliminates ammonia odor
• Signature Series Gold product reduces HAPs, free formaldehyde, and free phenols even more

"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.”
