Shell Hesive

Our ShellWeld product line offers both ready to use and high viscosity hot shell core and mold pastes that can be applied directly to hot shell cores and molds.

When applied to a hot shell core or mold, ShellWeld does not boil or dry out rapidly, thus allowing machine operators sufficient time to position cores and mold halves.

Our ShellWeld products also utilize a renewable resource (vegetable oil) as the liquid carrier and is a perfect companion to our Resin Coated Sand products for the Shell process.

Core Pastes

Our core paste adhesive line, CoreWeld, comes in two forms, standard and thick, to offer the most variability in set up time.

Our water based formula is a ready to use air dry pink paste that is silica free. It is ideal for automatic dispensing systems because it does not contain material that will abrade or wear out equipment.

Our acetone based formula utilizes a fast drying organic solvent that is not classified as a VOC or HAP and is strong in tensile strength and green in color for easy application.

Sand Gaskets and Files

Sand Gaskets
Sand gaskets are an extruded, rubber-like rope to be laid on the parting line of the mold which helps prevent “fins” and “run-outs” by providing a soft, pliable seal between cope and drag. Upon pouring, sand gaskets completely disintegrate to an ash and do not contaminate sand systems. It is a one-step application for effectively sealing your mold and is perfect for both the large, high production foundry and for the small jobbing shop.

HAI offers Files in 60, 80, and 120 Grit in a range of sizes and styles (flat, round, half-round) to meet your needs.

Product Features
Sand Gasket AF Various Sizes from 1/8" to 5/8"
Files Various Sizes in 60, 80, and 120 Grit
