Subject field(s)
  • Plastics Manufacturing

The blowing station is part of the equipment in which the mold is located when the blowing mandrel is inserted and the actual blow process occurs. The blowing mandrel introduces inflating air and shapes and calibrates the neck of the finished article.

English

Subject field(s)
  • Plastics Manufacturing
CONT

Pulforming is an offshoot of pultrusion. Resin-wet reinforcement is pulled through female mold cavities. The molds rotate on a turntable. The female cavities are enclosed by co-rotating male mold halves placed over them, or the female molds are covered by a rotating contact plate or belt. Each part cures as the closed mold rotates toward a cutoff station.

[La pultrusion courbe représente] une adaptation du procédé de pultrusion, qui permet, tout en maintenant une section constante, de donner une certaine forme à la pièce pultrudée. Dans la pultrusion, la filière, qui est fixe, est un moule dans lequel se déplace le renfort et c'est ce déplacement qui entraîne l'obtention d'une section constante sur la pièce fabriquée. En pulforming, on ajoute à une filière courte, non chauffée, une série de moules chauffés qui se déplacent et qui donnent à la pièce la forme désirée.

OBS

Le pulforming est quelquefois appelé pultrusion courbe.

Subject field(s)
  • Plastics Manufacturing
CONT

The [continuous extrusion blow-molding] process has three subcategories : the rising mold method, the rotary method, and the shuttle method. In the rising mold method, the parison is continuously extruded directly above the mold cavity. When it is at the proper length, the mold rises quickly to capture the parison and returns downward to the blow station. After blowing the bottle, the mold opens, the part is removed, and the process repeats.

Record 4 1997-11-04

English

Subject field(s)
  • Plastics Manufacturing
CONT

Intermittent extrusion is the second basic extrusion blow-molding category. In this process the parison is quickly extruded after the bottle is removed from the mold. The mold clamping mechanism does not need to transfer to a blowing station. Blow molding, cooling, and part removal all take place under the extrusion head, which also allows the clamping system to be more simple and rugged. The stop/start aspect of the extrusion method makes this process more suitable for polyolefin and other materials that are not heat-sensitive.

CONT

Extrusion discontinue. Dans ce type d'extrusion, la matière est plastifiée puis stockée soit dans un pot d'accumulation, soit dans une tête d'accumulation adaptée à cet effet.

In the common rising mold type of machine, the blow mold rises from below to close around the tube; the blow pin enters from the bottom.

In the rising mold method, the parison is continuously extruded directly above the mold cavity.

CONT

Certaines machines fonctionnent avec un seul moule : après avoir saisi et sectionné le tube sous la tête d'extrusion, le moule est amené sous une canne de soufflage qui s'introduit dans la paraison. Lors de l'ouverture du moule, l'article reste suspendu à la canne de soufflage, tandis que le moule est reconduit sous la tête d'extrusion. Après ouverture du moule, l'article fini, libéré de la canne de soufflage est ébarbé automatiquement et transféré sur un rail de transfert (système Kautex).

Record 6 1997-10-28

English

Subject field(s)
  • Plastics Manufacturing
CONT

Shuttle continuous extrusion blow-molding machine. Molds on this dual-sided system alternately move to capture a parison.

OBS

The [continuous extrusion blow-molding] process has three subcategories : the rising mold method, the rotary method, and the shuttle method.... In the shuttle method a blowing station is located on one or both sides of the extruder. As the parison reaches the proper length, the blow mold and clamp quickly shuttle to a point under the extrusion head, capture and cut the parison, and return to the blowing station. With dual sided machines, the clamps shuttle on an alternating basis. For increased production output, multiple extrusion heads are used.

Key term(s)
  • shuttle method
  • shuttle mold system
  • shuttle mould system
  • shuttle blow moulding machine
  • shuttle-type reciprocating molds
  • shuttle continuous extrusion blow-moulding machine
  • shuttle continuous extrusion blow molding machine
  • shuttle continuous extrusion blow moulding machine

Pour la réalisation de corps creux jusqu'à une capacité de cinq litres environ en matières plastiques pouvant être thermosensibles [...] à des cadences élevées, l'extrusion-soufflage à extrusion continue s'est imposée. [...] Deux familles d'équipements ont été développées : les machines alternatives et les machines rotatives, ces dernières comportant de nombreuses variantes. [...] a) Machines alternatives. Dans ce type de machine, le moule vient se refermer sous la filière de la tête d'extrusion et emprisonne une longueur de paraison correspondant à la hauteur du moule. Simultanément, un dispositif de coupe [...] sectionne la paraison et le moule se déplace vers le poste de soufflage. Pendant ce temps, la paraison suivante est extrudée et sera à nouveau happée au cycle suivant après ouverture du moule et extraction de l'objet précédent. Le rendement de ce type de machine a été amélioré par l'utilisation de 2 porte-moules à mouvements symétriques par rapport à la tête d'extrusion.
