Le projet a commencé par la conception et la fabrication d'un prototype de moule. La conception de ce moule était fondée sur la conception du produit fini. Toutefois, elle a été modifiée afin de tenir compte des indicateurs de mesures qui, durant les essais, permettent d'obtenir des données précises sur le retrait vertical et horizontal ainsi que sur les changements de volume.

The project began with the design and manufacture of a prototype mould. The mould design was based on the final product design. However it was modified to include measurement indicators, which during test runs could provide precise data about vertical and horizontal shrinkage as well as changes in volume.

Le chauffage et le refroidissement du moule pour liquéfier le plastique exigeaient des cycles de chauffage rapides dans une large gamme de températures. Les moules en aluminium de haute qualité ne pouvaient résister sans dommages à ce traitement.
Compare text pagesCompare HTM pagesOpen source URLOpen target URLDefine cra-arc.gc.ca as primary domain
Heating and cooling the mould in order to liquefy the plastic required that the mould be rapidly cycled through a wide range of temperatures. This was causing damage to the high grade of aluminium used in the mould. We then had to design and add special wear plates and determine if these could resolve this problem.

The mould was then returned to Canada and modifications were made to the mould based on these results. The modifications included changes to the design indicator locations and cnc machining. The mould was retested at the same Canadian site with the same conditions. Further data was collected during the production of samples. The samples were again analyzed and variables determined based on the results of this second test. A third iteration was carried out before satisfactory results were obtained.

Un moule prototype a été créé pour produire des pièces de la même épaisseur que le produit final, mais seulement d'un pied carré de surface. Ces pièces ont permis d'effectuer des essais mécaniques qui ont révélé des propriétés assez différentes de celles qui étaient prévues.

A prototype mould was built to produce parts with the same thickness as the final product, but only one foot square. The parts produced were subjected to mechanical testing which showed that the strength properties were significantly different from the predictions. The mould was systematically altered until it yielded parts that met the design criteria.

L'avancement de la technologie consistait en l'établissement de paramètres de conception et de fabrication permettant d'assurer la conformité aux exigences strictes de dimensions en cours de production, peu importe le lieu de production du moule ou de la bouteille.

The technological advancement was the establishment of design and manufacture parameters which would ensure that the strict dimensional requirements would be obtained in production, regardless of where either the mould or the bottle was produced. The technological advancement identified the critical parameters and provided a means of determining the variables that were used during the design of the mould to control its volume. The experimental work would provide improved "predictability".

Il a aussi fallu trouver une méthode de manutention des thermoplastiques pendant le moulage par compression. Nous avons rapidement constaté que le plastique fondu ne pouvait pas être injecté assez rapidement dans un moule de cette taille.

We had to develop a way to handle thermoplastics for compression moulding. We soon found that melted plastic could not be injected rapidly enough into a mould this large. We therefore developed a process wherein plastic granules would be laid into the mould, which was then be heated until the plastic liquefied and filled the entire cavity of the mould. The mould was then cooled.

Le problème suivant à surmonter était le dégagement de la pièce coincée dans le moule par le retrait. Il fallait trouver une méthode pour sortir des pièces aussi lourdes sans endommager le moule ni briser la pièce.

The next problem to be overcome was locking of the part into the mould because of shrinkage. We therefore had to determine how parts this heavy could be removed from the moulds without damaging the moulds or cracking the part. We had to develop a series of spring-loaded knockout mechanisms that were built into each mould to avoid redesigning and rebuilding the presses. A moving machine platen would push the knockouts forward, thereby ejecting the part.

Le retrait de la matière a créé un autre problème inattendu en coinçant la pièce dans son moule. Les moules de compression classiques comportent une boîte de démoulage contenant des broches et des plaques qui se lèvent à l'unisson pour éjecter la pièce.

Shrinkage of the parts resulted in an unexpected locking of the part into the mould. A traditional compression mould contains a knockout box containing knock out pins and plates that move in unison. Since this could be incorporated into the moulding machine without a complete redesign and rebuild, we had to design and build a series of self-contained individual spring loaded mechanisms. The challenge was to design and locate these knockout pins so that they would move together and avoid cracking of the parts.

In order to reduce material cost and improve cycle time during the preform injection process, the company had decided to reduce the weight of an existing plastics bottle by 5% for a juice application. Since it was uncertain whether the lighter weight container could still satisfy all physical properties and specifications, it was necessary to proceed with a prototyping injection mould to manufacture the new preforms. The lighter weight preforms were subsequently blown into the same juice container for testing. During the development of this lighter weight container, it was found that the bottle satisfied all the specified requirements, except the top load condition, i.e. the bottle was collapsing when the specified force was applied to the top of the container.
