In a modern injection molding machine, the pellets are conveyed forward within the barrel by a rotating screw, and melt as they go. The molten plastic is deposited at the forward end of the barrel, displacing the screw backward. When enough material has been plasticized, a hydraulic cylinder pushes the screw forward, forcing the molten plastic ahead of it through a nozzle, sprue, runners, and a narrow gate into a water-cooled mold cavity, where the molten plastic solidifies.  2, record 4, English, - injection%20machine

Les premières presses à injecter comportaient un piston poussant la matière ramollie dans la buse [...] Dans les presses actuelles, la plastification est assurée par une vis sans fin, analogue à celle d'une extrudeuse. Cette vis [...] fait alternativement fonction de piston d'injection et de vis de plastification.  2, record 4, French, - machine%20%C3%A0%20injecter

... preplasticizing machine. Of the equipment in use today, 95% is preplasticizing; either with a reciprocating screw or a screw-pot. In a reciprocating screw the melted material is collected in front of the screw, which continues to move backward against a controlled pressure as more material is melted. The area where the melted material is collected corresponds to the pot in a two-stage machine. When the screw is pushed forward by the hydraulic injection cylinder(s), a check valve (nonreturn valve) is closed. At this time the screw and nonreturn valve act like a plunger.  1, record 5, English, - two%2Dstage%20screw%2Dplunger%20machine

The plunger machine heats the material by conduction. Since plastic is an insulator, the material next to the outside wall is much hotter than that nearer the center. The laminar flow in the plunger-type cylinder does not reduce the temperature differential. ... The plunger machine in now only used to produce special effects (mottling, for example); the two-stage plunger machine is obsolete. It is used in thermoset IM for glass-reinforced polyester because it reduces glass fiber breakage.  4, record 6, English, - plunger%20injection%2Dmolding%20machine

La presse à piston, celle décrite dans le principe, est la plus ancienne. La matière fondue est poussée du pot d'injection au moule par un piston (analogie avec le moulage des alliages légers sous pression). L'avantage principal réside dans la simplicité de la machine mais la matière, pour un diamètre de fût important, reste insuffisamment plastifiée puisqu'il existe un gradient de température entre l'axe et la paroi du fût.  1, record 6, French, - presse%20%C3%A0%20piston

La machine la plus utilisée est la presse à vis-piston. On parle alors de préplastification; en effet la vis assure ici deux fonctions : -fonction vis en tournant sur son axe : plastification de la matière de façon homogène, -fonction piston en avançant le long de son axe : matière poussée dans le moule par l'extrémité de la vis (qui joue le rôle de piston).  1, record 7, French, - presse%20%C3%A0%20vis%2Dpiston
