Abstract
A synthetic resin-made intake manifold including a volumetric air-intake section communicating with an intake air supply source through an inlet pipe and a plurality of outlet pipes for connecting the volumetric air-intake section to cylinders of an internal combustion engine is fabricated by injection molding, by applying the die rotary injection method or die slide injection method, the volumetric air-intake section and the outlet pipes respectively, thereafter, assembling them together and joining into unity, so that a synthetic resin-made intake manifold adapted for efficient production and flexible designing or including outlet pipes of a complex shape is obtained.
