Abstract

The riser or feeder is a metal storehouse that is attached to pieces with the aim of compensating for the metal contraction phenomenon and of avoiding internal soundness defects known as cavities or porosities, which result in the rejection of pieces in the casting process.
This invention aims at obtaining better feeding head efficiency than is achieved at present, whether coated or not, the cost of which will be less and which will not need any coating.
The riser is made up of a single element, which is moulded at the same time as the rest of the piece mould. It consists of an upper chamber, vertical or quasi-vertical, a bottom chamber, which is wider, and at least one conduit that stems from the bottom chamber, through which the metal flows from the feeder to the piece.
