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.

Disclosed is a method for manufacturing a container (2) from a blank (3) made of plastic material, in a stretch-blow molding unit (7) including: a mold (11) provided with a wall (13) and a mold base (14) which is axially movable relative to the wall (13) between a low position and a raised position; a stretch rod (22) which is axially movable relative to the mold (11) between a high position and a low position; the method including: a phase of inserting the blank (3) in the mold (11); a phase of stretch-blow molding; a phase of boxing; a phase of determining the start and end of the boxing phase, respectively, by detecting the movement of the rod (22) from the low position thereof and the stopping of the rod (22) at the raised position thereof.

A method for manufacturing a resin container part includes: injection-molding of a bottomed resin preform including, on a bottom portion thereof, a thick bulging portion that retains residual heat by which the bulging portion is deformable by being pressed to follow a shape of a blow cavity mold; and a blowing including stretching a body portion of the preform by applying a blow pressure to the preform and forming a joint portion by pressing the bulging portion of the preform with an upper bottom mold to deform the bulging portion to follow the shape of the blow cavity mold.

A blow molding apparatus including: a mold; a blow nozzle; a pressurized fluid supply unit; and a blow nozzle moving unit configured to cause a relative movement of the blow nozzle between a connected position and a standby position, wherein a preform is molded into a container by supplying a pressurized incompressible fluid into the preform. The blow molding apparatus includes: a drawing member including a drawing port; a drawing pump configured to be connected to the drawing member; and a drawing member moving unit configured to move the drawing member so that the drawing port is positioned below the blow nozzle, after the container has been molded and the blow nozzle has been moved from the connected position to the standby position.

A method for transferring a negative structure of a surface of an inner wall (51) of a blow molding tool (1) onto a surface of a plastic container. The method comprises the steps of heating at least one region (511) of a mold cavity (6) of a molding body (4) of the blow molding tool (1), on which the negative structure is formed, inserting a preform into the mold cavity (6), closing the blow molding tool (1), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall (51) of the mold cavity (6), cooling the region (511) by supplying a coolant through temperature control channels (54), and removing the plastic container from the mold.
