Method of producing high-grade plastic parts and an injection-moulded part

摘要

A method of producing an injection molded part in which an insert is disposed within a mold cavity and extrusion coated with a plastic material fed via injection cylinder by layering at least one hard component and at least one soft component of a plastic material within the injection cylinder and then successively feeding the hard component followed by the soft component out of the injection cylinder into the mold cavity to extrusion coat the insert.
