Support apparatus for supporting at least one neck mold of a container in an injection blow molding machine

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.

Method for increasing the injection speed of a plastic injection device

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 BWTof the wall at the center of the gate or tip () (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 () helps to reduce the risk of stress cracking on the bottle base. Furthermore a step () having thickness WTin the body wall thickness, in the region of the periphery of the base with WT&#x3e;WT, allows enough material to be available for the proper blowing of the bottle bottom making the bottle more stable.
