摘要 |
<p>A manufacturing method of a shaft (6) provided with a magnet (24) for an air flow rate adjustment valve (1) in an internal combustion engine; the method presents the steps of: arranging a first mold (26) which negatively reproduces the shape of the shaft (6) and determines the formation of a seat (28) for the magnet (24); injecting a molten plastic material inside the mold (26) in order to form the shaft (6) provided with the seat (28) for the magnet (24) by injection molding; arranging a second mold (27) which surrounds the seat (28) for the magnet (24); and injecting a molten magnetic polymer in the second mold (27) for forming the magnet (24) by injection molding.</p> |
