Abstract: A process for molding one or more bottle preforms, wherein molten plastic is injected into at least one molding cavity; and wherein air is drawn from the at least one molding cavity, through at least one channel for the air to pass from the at least one molding cavity towards the outside of the molding device, by means of suction means; and apparatus and device for performing such a process.

Abstract: 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.

Abstract: A component of a mold for molding preforms made of thermoplastic material, comprising at least a first part (10) and at least a second part (20) adapted to mold part of the outer surface of a preform, wherein, when the first part (10) and the second part (20) are assembled to each other, at least a first surface (11) of the first part (10) and at least a second surface (21) of the second part (20) face each other and are spaced apart from each other, thus delimiting a passageway for gases or vapors to leave the mold; and wherein at least one of said first surface (11) and said second surface (21) comprises laser-induced periodic surface structures (LIPSSs).

Abstract: An injection apparatus for injecting molten plastic into a mold of articles made of thermoplastic material, comprising: at least one shutter (3) for opening or closing an injection nozzle (31); at least one cylinder-piston system (104, 204, 304) adapted to move said at least one shutter (3) from an opening position of the injection nozzle to a closing position of said injection nozzle and vice versa; wherein at least one cylinder-piston system (104, 204, 304) comprises a first chamber (142, 242, 342) provided with a first passage (144, 244, 344) for the introduction of fluid into the first chamber (142, 242, 342) to take the shutter (3) to the opening position; and a second passage (149, 249, 349), different from the first passage (144, 244, 344) for the exit of fluid and possible plastic particles from the first chamber (142, 242, 342).

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