The invention concerns an intake system, in particular an intake pipe of thermoplastic plastics for the intake air of an internal combustion engine with in particular cylinder rows arranged in a V-shape. The intake system comprises at least two elements (,), the first element (,) having a substantially closed shape and simultaneously forming the lower half-shell of the intake pipes. The second element (,) is designed as the upper half-shell of the intake pipes and is connected to the first element (,) by the plastics welding technique.

Intake system of thermoplastic plastics

A process for producing closed or open hollow parts of molded synthetic resin material in which a core (,) or mold body which extends into the mold cavity and is attached to a form element and supported on other form elements is situated between two mold half-shells. The core is supported by one or more movable stops (,) which can be retracted from the mold cavity. Plastic is injected into the mold via a first injection channel (,) with the core retained in position by the stops (,). Subsequently the retaining stops (,) are retracted and the mold cavity is completely filled via a second injection channel (,).
