A magnetic encoder in which a support member and a plastic magnet do not adhere to each other is manufactured using a mold. The plastic magnet has a turning molded portion on the outer circumferential side thereof. The gate of the mold is an inner-diameter-side disk gate and a length L thereof in the axial direction is in a range of 0.2 mm≤L≤0.6 mm. The tensile strength of the material of the plastic magnet is 65 MPa or more and the Young's modulus thereof is 4000 MPa or more and 15000 MPa or less. The method includes a step of opening the mold and placing the support member as an insert object in the mold, and a step of closing the mold and injecting a melted material of the plastic magnet into a cavity through the disk gate.

A method for making structural foam parts having continuous aligned fibers includes placing an assemblage of fiber-bundle-based preforms in an injection mold, creating a melt flow of resin and, optionally, short, loose fiber, and adding foaming agent to the melt flow. When the foaming agent/melt flow mixture is introduced into the injection mold, the foaming agent foams. The assemblage is structured and positioned so that fibers therefrom adopt a desired alignment and position in the final part. Structural foam fills the remainder of the volume of the part.
