摘要： An injection apparatus for injecting molten plastic into a mold of articles made of thermoplastic material including bottle preforms. The injection apparatus includes an injection nozzle and a shutter for controlling flow of the molten plastic through the injection nozzle. A cylinder-piston system moves the shutter from open and closed positions of the injection nozzle. The cylinder-piston system includes a first chamber with a first passage for introducing fluid into the first chamber to open the shutter, and a second passage, different from the first passage, for discharge of fluid and of possible particles from the first chamber. A fluid distribution device with a first channel is connected to the first passage, and a second channel different from the first channel is connected to the second passage. The cylinder-piston system includes a second chamber having a third passage for introducing fluid into the second chamber to close the shutter.

摘要： The invention relates to an apparatus for cooling a plurality of preforms made of thermoplastic material which continuously move on a conveyor belt. The apparatus includes a cylindrical casing with a vertical extension formed by two coaxial cylinders, such a casing contains a guide crossed by a chain or a cable for transporting the preforms therein. The guide, which forms a closed path, comprises a first helical stretch, which raises from the lower plane starting from a station in which the preforms coming from a conveying device are hooked by the chain or by the cable, a second straight stretch, which returns the preforms to the lower plane once they have reached the upper plane, and a third flat stretch at the height of the lower plane, which returns the preforms to the arrival station. The helical stretch of the guide is contained within a cooling tunnel formed in the gap between the two walls of the outer cylinder and the inner cylinder of said casing. The cooling air is conveyed within the cooling tunnel by a specific manifold which is located within the casing.

摘要： An injection mould component for moulding the outer surface of a preform neck, which allows improved cooling of the preform node inside the mould, while in the same time reducing the mould cycle time. A related production process of said injection mould component, which allows the section of the cooling channels to be optimized, determining a more effective cooling, is also described.

摘要： The invention relates to a new PET preform design that enables a more precise distribution of material in the bottle bottom and avoids the waste of material around the injection point. The thickness BWTmin of the wall at the center of the gate or tip (3) (injection point) is reduced to a minimum in order to avoid the waste of material around the injection point when the preform is blown. This is particular important for carbonated soft drink application since the reduced amount of amorphous material at the center of the gate (3) helps to reduce the risk of stress cracking on the bottle base. Furthermore a step (4) having thickness WTmax in the body wall thickness, in the region of the periphery of the base with WTmax>WT, allows enough material to be available for the proper blowing of the bottle bottom making the bottle more stable.
