Combicore cores for foundries
Foundries make complex channels in cast pieces with combicore cores that are not presentable with conventional methods (slider, drilling, empty tubes).
Combicore casting cores as simple version consist of a metal tube that is filled with a molding material. The filled tube is drawn through a cavity and its diameter is being reduced. The molding material in the metal tube is compressed and compacted.
The final form of the cores is made on bending machines and if applicable with compression molding. Furthermore, individual cores can be joint to channel systems that can be easily inserted in the casting mold. The surface of the inlay tube can be treated as needed.
After casting the molding material is removed out of the tube. The core casing stays in the cast piece and represents the channel wall.
