Intrusion molding. When heavy sections are molded or when the shooting capacity of the machine is not adequate, intrusion molding can be used, where the screw turns continually and fills the cavity directly. When the cavity is filled, a cushion is extruded in front of the plunger, which then comes forward to supply the needed injection pressure.  5, record 5, English, - intrusion%20moulding

Intrusion. But : fabriquer des pièces très épaisses, pour lesquelles la capacité de plastification de la machine est trop faible. Principe : Le dispositif de plastification extrude la matière dans le moule et le remplit. La compression de la matière peut se faire de 2 manières : -Par la pression d'extrusion de la machine (utilisation d'une extrudeuse, ou blocage du recul de la vis d'une presse d'injection). -Par la pression d'injection de la presse. Dans ce cas, la machine plastifie de la matière jusqu'à un dosage voulu. Ensuite, injection de la matière, comme dans le cas d'une injection classique.  3, record 5, French, - intrusion

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 6, English, - injection%20machine

... 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.  3, record 9, English, - screw%2Dinjection%20molding%20machine

Reciprocating screw systems. In a reciprocating(in-line) screw, the material is fed from the hopper, plasticized in the screw, and forced past a one-way valve at the injection end of the screw. The material accumulates in front of the screw, forcing back the screw, its drive and motor, and the pistons of the two hydraulic injection cylinders.... When the screw reaches a certain position, it contacts a limit switch that stops the rotation. When the cycle is ready to inject, two hydraulic injection cylinders, one on each side of the carriage, move the screw assembly forward and use the screw as an injection ram.  1, record 11, English, - reciprocating%20screw%20system

The injection screw is divided into three parts. The first half of the screw compresses the material and removes the air. The flight depth is constant. The second part(third quarter) of the screw has decreasing flight depths, thus reducing the volume. Reduction of the volume increases the friction of the polymer molecules as they rub over each other, increasing the temperature. At the end of this section all the material should be melted(plasticized). The third part(last quarter) of the screw is a pump. The flight depth is constant but smaller than the first section because melted material takes up less volume than powder.  2, record 12, English, - injection%20screw
