The blowing temperature correcting section (63) corrects the blowing temperature, at a starting stage, to a start regulation value set to a temperature value higher than a warming value.

The associated slow rise in the temperature of the air blown in by the ventilation and the increase in humidity can be annoying for passengers.

  The blowing temperature correcting section (63) corrects the blowing temperature, at a starting stage, to a start regulation value set to a temperature value higher than a warming value.

The softened polymer is then heated to a temperature at which the blowing agent is activated.

High temperature polyamide resin compositions for blow molding and articles blow molded from such compositions are provided.

Furthermore, the blowing agent contained in the heat-expandable pressure-sensitive adhesive layer preferably has a blowing initiation temperature exceeding 80°C.

A blower (30) feeds room temperature air into the mixing space (20).

In the secondary blow molding, the mold temperature exceeds 210ºC.

The polymer is initially heated to a temperature at or above its softening temperature, but below the temperature at which the blowing agent becomes activated, to soften the polymer.

It comprises a blank moulding station, a preform blowing station, at least one temperature compensating station, a station for drawing and blowing the hollow body and an evacuation station.

The container is produced from a tempered preform and by means of blow pressure effects.

The blow-moulding process can be an extrusion blow-moulding process or a stretch blow-moulding process.

Said air supply outlet temperature of the supplied air is measured by at least two air supply outlet temperature sensors which are located at the air supply ducts that terminate in different sites of the interior.

A blow outlet is constructed of line blow outlets (35) and corner blow outlets (36).

The blow molded shoulder section (22) is heated at a lower temperature than the barrel section (24).
