A component (') of a molding apparatus (′) for producing hollow plastic items, in particular test tubes, syringes or tubular bodies, the component (′) comprising: —a first body (″) having a face () defining part of a separation surface of the molding apparatus (′); —a second body (′), or stripper ring, inserted in the first body (′), adapted to be crossed along an axis (X) by a core (), and in particular to come into contact with the core (); —a plurality of elements (′) inserted in the first body (′), adapted to be displaced parallel to the axis (X); in which the second body (′) has an outer surface () comprising a plurality of inclined portions (′), in particular with respect to said axis (X); and in which each element (′) of said plurality of elements (′) has an outer surface comprising an inclined portion (′), in particular with respect to said axis (X), which is in contact with a respective inclined portion (′) of the second body (′) so that the position of the second body (′) can be adjusted by means of said plurality of elements (′).

Component of apparatus and apparatus for molding plastic products, in particular with thin wall thickness

A component of a mold for molding preforms made of thermoplastic material, comprising

Preform mold component

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.

Apparatus and process for molding bottle preforms

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.

Injection apparatus for plastic preforms

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.

Process of manufacturing an injection mould component

An injection mould component for moulding the outer surface of a preform neck, which allows improved cooling of the preform neck inside the mould, while at 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 optimised, determining a more effective cooling, is also described.

Injection mould component for preforms made of plastic material

A blowing mold with a cam control device for making undercuts related to the application of handles on a container made of plastic material, where the undercuts ensure that the handles are mechanically fixed to the container body and where the system has an independent actuation for each undercut.
