MANUFACTURE OF COOLING PUMP ROTOR FOR CAR |
摘要 |
A method for the manufacture of a closed plastic pump rotor is described. The mold comprises two outer casting mold shells and an intermediate core, whose shaping determines the shape of the guide vanes and flow channels of the rotor. The core is made from a material, whose melting point is below that of the plastic to be cast. The core is melted following the curing of the plastic. |
