Abstract
A can of a drive motor is provided for a pump assembly, wherein the can (22) is manufactured at least partly of plastic (52). At least in a part of the can (22) the plastic (52) is reinforced by individual fibers (32) distributed in the plastic (52). The fibers (32) in at least one layer (35) of the can (32) are aligned in a defined manner in the peripheral direction with respect to the longitudinal axis (Z) of the can (22). A method for manufacturing such a can is also provided.

A can of a drive motor for a pump assembly, wherein the can (22) is manufactured at least partly of plastic (52), wherein at least in a part of the can (22) the plastic (52) is reinforced by individual fibers (32) distributed in the plastic (52), and wherein the fibers (32) in at least one layer (35) of the can (22) are aligned in a defined manner in a peripheral direction with respect to a longitudinal axis (Z) of the can (22).
A method for manufacturing a can of a drive motor for a pump assembly, the method comprising the steps of:
- admixing individual fibers (32) with fluid plastic (52) for reinforcement, introducing the admixture into an injection molding tool defining a shape of the can (22) to be manufactured, and rotating an inner mold part (2) of the injection molding tool relative to an outer mold part (12) of the injection molding tool during and/or after the introducing step.
