Warm Box Systems & Shell Resins

  • Foundries interested in increased productivity appreciate the diversity of performance capabilities offered by HAI's Warm Box and Shell Resins.


  • HAI’s leading Warm Box Resin, Envirotherm, is designed for use in a broad variety of casting application. It is a high tensile strength resin that provides improved core quality, reduced cycle times and lower cure temperatures.
  • HAI produces the most complete line of liquid and solid phenolic shell resins in the foundry industry, including our leading Shell Resin, Plastiflake.

"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.”
