Engineered Sand Additives

Engineered Sand Additives

CastTherm® Korplete Engineered Additives Sand alone is a low cost molding and core media, but it has limitations subject to shape and thermal properties. Binder systems add complexity with the addition of an organic component. Engineered additives used to preventing casting defects have a net benefit to the mix.

 

A small addition can remedy several common defects such as surface-based defects, gas reduction, as well as reduce time in the cleaning room. Engineered additives can also be used to modify the sand mix to eliminate the need for coatings or the need for a more expensive specialty sand.

 

Considered benefits through the use of CastTherm Korplete additives: CastTherm Korplete Organic Additives Effective at low addition rates General lower temperature applications Lower cost Improves flowability of sand CastTherm Korplete Inorganic Additives Effective at low addition rates No VOCs, gas, smoke or odor High hot strength properties.

"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.”
