摘要 |
A manufacturing method of a shaft provided with a magnet for an air flow rate adjustment valve in an internal combustion engine; the method presents the steps of: arranging a first mold which negatively reproduces the shape of the shaft and determines the formation of a seat for the magnet; injecting a molten plastic material inside the mold in order to form the shaft provided with the seat for the magnet by injection molding; arranging a second mold which surrounds the seat for the magnet; and injecting a molten magnetic polymer in the second mold for forming the magnet by injection molding.
