Core connector attaches cores together. (New Product).

Cores often are attached to produce core packages or complex cores made in several pieces. Common processes for this connection include shooting a connecting core or gluing two cores together.

As an alternative to these methods, Core-Lock, a new core connection technique, has been developed by Hottinger Systems GmbH, Germany (represented in the U.S. by Hottinger North America, Inc., Taylor, Michigan).

Two cores that need to be connected have conical pins and corresponding conical holes. A star-shaped core connector consisting of a special fabric with high tensile strength is placed between pin and hole, Pressing the two cores together immediately results in a strong connection due to wedge and friction forces. The core connector also prevents the sand from peeling off the core surface.

The process offers high tensile strength and enough heat resistance for drying operations. During shakeout and thermal sand reclamation, the connectors burn completely without emitting any environmental burden
