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%."
