coreforming
Coreforming is a manufacturing method used to create hollow, thin-walled, or internally feature-rich parts by forming and assembling a detachable core within a mold or assembly, which is later removed. The core’s geometry defines internal passages, cavities, or undercuts that cannot be produced by the external shape alone. Coreforming spans several industries, including metal casting, glass and ceramics, and increasingly additive manufacturing.
In metal casting, cores are typically made from sand bonded with a binder or from ceramic materials.
In investment casting and ceramic forming, wax or ceramic cores can be used to generate complex internal
Removal of cores is a key phase and can involve mechanical extraction, dissolution, or breaking apart reusable
