Tubular, ported air duct and method for manufacturing the same

A ported tubular air duct and a method for manufacturing a side-ported tubular air duct. The air duct has a side port located substantially ninety degrees (90°) to the part line of a mold in which the air duct is manufactured. The mold has two portions which are separated when the mold is opened to permit the positioning a preheated polypropylene tubular port insert member into an opening in one of the mold portions. A parison of rubber modified polypropylene is injected into the mold between the portions at approximately 410° F., and the mold is closed to seal the ends of the parison. The interior of the parison is pressurized to a level in the range of approximately 90 to 100 psi to force the parison outward against the inner sides of the mold cavity and against one end of the port member. At this juncture, the parison has a thickness in the range of 0.060 to 0.090 inches. The parison expands into the opening of the tubular port insert member and is burst by the pressure in the parison such that the parison material flows along the interior of the tubular port insert member and merges therewith. The pressurizing medium, preferably air, is allowed to flow through the port and out of the mold for approximately 10 seconds. A mandrel is then urged into the tubular port insert member so that the system again be fully pressurized. The molded air duct remains in the mold until cooled. The pressure is relieved, the mandrel is withdrawn and the part is removed from the mold.

Process For Manufacturing A Fuel Tank Equipped With An Internal Accessory

Process for manufacturing a fuel tank equipped with an internal accessory and having a plastic wall produced from a parison, the process including, in order, the following steps: a) the accessory and the molten parison are introduced into a mould so that the accessory is surrounded by the parison, the mould including cavities equipped with at least one moving part; b) a pressurized gas is introduced inside the parison to carry out a pre-blow moulding of the parison; c) the pre-blow-moulded parison is pressed locally against the accessory using the moving part in order to firmly attach the two without piercing the parison; d) the mould is closed and the final blow moulding of the parison is carried out by flattening it against the mould cavities using the pressurized gas; and e) the tank is removed from the mould.

Method of forming a blow-molded plastic part having a living hinge

A method of forming a carpeted plastic part includes positioning a carpet between first and second mold halves, wherein the carpet has a back surface. A non-reinforced plastic strip is positioned adjacent a portion of the back surface of the carpet. A hollow parison of reinforced plastic material is formed between the first and second mold halves. The first and second mold halves are then closed together to form a carpeted plastic part having a thinned-down region of the reinforced plastic material adjacent the plastic strip such that the plastic strip is sandwiched between the thinned-down region and the carpet to form a flexible living hinge.

Damper for air lines of an internal combustion engine having a turbocharger and method for producing said damper

A method for producing a damper for an air line of an internal combustion engine includes the following steps: providing a temperature-controlled inner part having passages; producing a tubular preform of an outer jacket from a thermoplastic melt; and attaching the temperature-controlled inner part to a blowing mandrel of a blow mold, which is open. The blowing mandrel has outlet openings and the passages are positioned over the outlet openings. The method further includes bringing the temperature-controlled preform over the inner part and closing the blow mold such that the preform is blown against the walls of the blow mold, whereby an outer jacket is obtained. Simultaneously, local connections between the inner part and the outer jacket are obtained by pressing the preform and the inner part against each other in some regions. Finally, the blow mold is opened and the damper is removed.
