An injection molding system comprising: a first selected valve, one or more downstream valves, delivering a fluid to a mold cavity, at least one fluid property sensor, each valve associated with a position sensor that detects opening of a gate at an actual open gate time to the controller, the controller automatically adjusting time of instruction to open the gates on a subsequent injection cycle by an adjustment time equal to any delay in time between a predetermined open gate target time and an actual open gate time, wherein the system forms a first one or more parts or objects, the user inspecting or measuring the first one or more parts or objects and manually adjusts the predetermined open gate target time.

An apparatus for aligning an outlet of an injection unit with an inlet of a mold mounted between platens of a molding machine includes a positioning assembly interconnecting the injection unit to the molding machine. The positioning assembly includes a first translation assembly configured to engender a first movement of the injection unit outlet along a translation plane, and a second translation assembly configured to engender a second movement of the injection unit outlet along the translation plane. The positioning assembly further includes a brake assembly extending between the first translation assembly and the second translation assembly. The brake assembly is configured to selectively create a compressive force between the first and second translation assemblies to maintain the position of the injection unit outlet.

A method and device for producing an optimized neck contour on preforms below the neck which is optimal for subsequent stretch blow molding. The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding. The thin-walled geometry on the preform can be produced outside of the mold during post-cooling by embossing. The preform is then removed in a cooled receiving sleeve and is cooled in the body by intensive contact cooling while no cooling contact is made with the preform neck due to the initial position of the embossing element. Due to the reheating of the neck they can be mechanically deformed into a new geometry advantageous for blow molding and thus wall thickness can be influenced.

A shaping machine includes a stationary first mold mounting plate, a second mold mounting plate movable with respect to the first mold mounting plate, a tubular snorkel fixedly secured to the second mold mounting plate, and an injection unit for plasticizing and injecting a molding material. An abutment is designed so that, in the opened condition of the closing unit, the injection unit can be braced against the abutment, and so that, in a closed condition of the closing unit, the injection unit is freed from the abutment by the force action of the snorkel on the injection unit.

Provided is a blow molding machine including an injection molding unit and a blow molding unit, wherein the injection molding unit includes a preform mold and an injection device configured to supply resin to the preform mold, wherein the injection device is fixed to a support plate, and wherein the support plate includes a position adjustment mechanism capable of adjusting a position of the injection device in an upper and lower direction with respect to the preform mold.
