A resin material is injection-molded using an injection mold in which a resin flow channel is designed so that a plurality of gates are provided along a longitudinal direction at a position corresponding to an inner circumferential surface of a spacer, to obtain a molded product, the spacer having a shape that a plurality of arc-shaped circumferential surfaces are linked through a constricted part. The molded product is cooled in a state in which a runner that is connected to the gates is allowed to remain, and the runner is cut off thereafter. A water jacket spacer is produced by injection molding while achieving excellent moldability, the water jacket spacer being disposed in a water jacket, and controlling the flow of a coolant, the water jacket spacer including a plurality of segments, or having a shape that the water jacket spacer can be partially inserted into the water jacket.

A system includes a mandrel contoured to define a tapering tubular shape of a workpiece cured on the mandrel and a demolding tool. The demolding tool is configured to remove the workpiece from the mandrel after the workpiece is cured on the mandrel and cut longitudinally. The demolding tool is configured to remove the workpiece from the mandrel by deforming a first end of the workpiece to at least partially disengage the first end of the workpiece from a first end of the mandrel, and subsequently, deforming a second end of the workpiece to at least partially disengage the second end of the workpiece from a second end of the mandrel. The first end of the workpiece may have a first cross-sectional area that is smaller than a second cross-sectional area of the second end of the workpiece.

The invention relates to a method for encapsulating electronic components mounted on a carrier, including the steps of: placing the carrier with electronic components in a mould, introducing a liquid encapsulating material into the at least one mould cavity, wherein the pressure on an upper side remote from the carrier of at least one calibration component mounted on the carrier is measured by at least one pressure sensor located in the contact surface of a mould part. The invention also relates to a mould for encapsulating electronic components mounted on a carrier with such a method.
