Patent ID: 8460596

Claim:
A process for producing a homogenous mold core that can be used for manufacturing a composite part, said mold core comprising at least one powdered and/or granular material, the process comprising the steps of: providing a mold positioned on a support whose slope is adjustable to allow gradual filling of the mold by gravity, said mold delimited by a cavity wall whose geometry is adapted to that of the core to be produced, and said support mounting a vibration source adjacent to said mold; flattening the periphery of a hollow outer mold core envelope against said cavity wall; filling at least one powdered and/or granular material into the area delimited by said flattened periphery, said filling occurring gradually, by gravity, and in a longitudinal direction extending along said slope; and emitting vibrations from said vibration source into said material within said flattened periphery and within said mold simultaneously during filling, wherein said vibrations are emitted slightly above a gradually rising fill level of said material for the entirety of said filling by gradually moving said vibration source along both of said support and said longitudinal direction to position said vibration source slightly above said fill level simultaneously during filling, and wherein the slope of said support is adjusted prior to said filling to form a non-zero angle formed between a horizontal direction and said longitudinal direction.
