Patent ID: 10513059

Abstract:
A method for manufacturing a wheel including a step (a) during which a liquid to be polymerised is cast into a first mould so as to solidify same into a tubular preform, with main axis, the first mould including modelling cores in order to form recesses, of the rib type, in the radial thickness of the tubular preform; followed by a cutting step (b), during which the tubular preform is cut perpendicular to the main axis thereof, and secant to the recesses, so as to obtain a tubular preform section forming a rim; followed by an overmoulding step (d), during which said rim is placed in a second mould, concentrically with a central supporting member, such as a bushing or a shaft, and a polymer filling material is injected so as to create an intermediate disc that provides the attachment of the rim to the central supporting member.
