Resin transfer molding(RTM)... uses a closed mold, in two or more parts, usually made of glass-reinforced polymers or light metal alloys, with injection points and vents to allow air to escape. Reinforcement is cut to shape and placed in the mold, together with any inserts or fittings.

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 11, English, - injection%20machine

The extrusion head used in blow molding is one of three basic styles : the spider or axial flow head, the side feed or radial flow head, and the accumulator head.... The side feed or radial flow head is a design most often used for polyethylene. Melt enters the head from the side, divides around the mandrel, and rewelds. As the melt moves downward, it enters the pressure ring area, creating a tremendous back pressure that helps ensure the resin reweld. The head is used for its simplicity and ruggedness, but has the disadvantage of relatively long color changes.  2, record 12, English, - side%20feed%20head

The extrusion head used in blow molding is one of three basic styles : the spider or axial flow head, the side feed or radial flow head, and the accumulator head. In the simplest form of the spider or axial flow head, a central torpedo is positioned in the melt flow path supported generally by two spider legs. The smooth and direct path with little or no place for material to hang up and degrade makes this head ideal for PVC resin. Cross-sectional areas of the melt flow path from the extruder, over the torpedo, and over the spider legs are carefully balanced to ensure an even and consistent pressure and flow.  2, record 13, English, - spider%20head

What makes automatic molding automatic is the mold. There are a number of requirements for automatic molding. The machine must be capable of consistent, repetitive action. The mold must clear itself automatically. This means that all the parts have to be ejected using a runnerless mold, or that the runner and the parts have to be ejected in a conventional mold. There may be some method for assisting in the removal of the pieces, usually in the form of a wiper mechanism, air blast, or robot. All machines used automatically must have a low-pressure closing system to prevent the machine from closing under full pressure if there is any obstruction between the dies. The machine shuts itself off and/or an alarm is sounded. Automatic molding does not necessarily eliminate the operator. Many times, an operator is present to pack the parts and perform secondary operations. Automatic molding gives a better quality piece and more rapid cycle. In automatic molding an experienced person usually attends several machines. Unless the powder feed and part removal are automated, this person takes care of those operations.  1, record 14, English, - automatic%20molding

Another process somewhat related to extrusion blow molding is the extrusion/molded neck process. Still used today by Owens-Illinois, this is a proprietary process that traces its roots to glass-blowing technology. It is unique in that the bottle neck finish is injection molded and the bottle body is extrusion blow-molded. In this process, the two halves of a neck finish cavity or neckring are mounted to an actuating head assembly, which intermeshes with the two halves of the blow-mold cavity. The process cycle begins with the main body mold cavity open and the neckring cavity closed. The actuating head assembly moves downward to contact the extrusion die head. When it is in position, extrusion pressure fills the neck section with plastic melt. After it is held for one to two seconds, the head assembly moves upward while, simultaneously, the parison is extruded. When the head assembly reaches the top of its stroke, the blow-mold cavity closes on the parison. The remaining steps of parison pinch-off, blowing, and part removal all follow conventional techniques. Although the production cycle is somewhat slow, the process offers the quality advantage of an accurately molded neck and the process advantage of a parison held at both ends.  1, record 15, English, - extrusion%20molded%20neck%20blow%2Dmolding%20process
