For example, a molding system () to manufacture a molded article () in a mold-cavity system () by using a molding material () is provided. The system () including pressure-control system () coupled with the system (); and controller () operatively coupling to system (), controller () having controller-usable memory () tangibly embodying set of controller-executable instructions () to direct controller (), including mold-unpack instructions (), including instructing controller () to control system () to reduce, after solidification, at least in part, of material () being located in a nub region () of system (), internal pressure of material () received in system () while system () remains isolated from stream of flowable-molding material, beyond any reduction of internal pressure in material () resulting from cooling of material (), so that reduction in internal pressure of material () is enough to permit safe opening of system () while permitting safe extraction of article ().

Method and system for operating an injection molding machine

Disclosed, amongst other things, is a method of post-mold cooling of a molded article, the molded article having just been molded within mold halves, the method comprising: receiving, in a post-mold device, the molded article; subjecting the molded article to post-mold cooling, the post-mold cooling including: implementing a first post-mold cooling process portion in the post-mold cooling device at a first temperature; and implementing a second post-mold cooling process in the post-mold cooling device portion at a second temperature, said second post-mold cooling temperature being greater than said first post-mold cooling temperature; determining a switch point; triggering at the switch point, a transition from the first post-mold cooling process portion to the second post-mold cooling process portion.

Method and apparatus for post-mold cooling a molded article

Embodiments of the present invention teach a post-mold treatment device and post-mold preform receptacle for use therewith for a post-mold treatment of a preform having a bell-shape. More particularly, an upper portion of a receptacle cavity associated with the post-mold preform receptacle is configured to have the same shape as the transition portion of the preform, and the upper portion is further configured to have a transition-fit size with respect to the transition portion of the preform at the instant that the preform is received from the molding cavity of the injection mold.

Post-mold preform receptacle and a post-mold treatment device

According to embodiments of the present invention, there is provided an apparatus for controlling melt flow through a portion of the melt distribution network. A flow control device is provided. The flow control device comprises a body defining: a mixer configured to be positioned in a conduit for providing a path of flow for melt such that the mixer traverses substantially the whole cross-section of the path of flow; a temperature control portion associated with the mixer for actively controlling temperature of the mixer.

Apparatus for controlling melt flow in a melt distribution network

According to embodiments of the present invention, there is provided an air dehumidifying sub-system and a method for use in a molding system. For example, the air source device for use with a post-mold treatment device for treating a molded article, the air source device comprising: an air inlet and a refrigerating unit operatively coupled to the air inlet, the refrigerating unit and the air inlet arranged such that air is forced between the air inlet and the refrigerating unit for cooling the air; an air outlet coupled to the refrigerating unit for connecting the refrigerating unit to an air management device of the post-mold treatment device, the air management device configured to direct, in use, cooled air onto a portion of the molded article being treated.

Air source device and a method for use in a molding system

Embodiments of the present invention teach a method for post-mold treatment of a molded article and an apparatus for implementing the method. For example, a method of post-mold treatment of a molded article is provided. The method can be implemented in a molded article receptacle. The method comprises at a first instance in time, subjecting the molded article to a first type of post-mold treatment; and at a second instance in time, subjecting the molded article to a second type of post-mold treatment.

Method for post-mold treatment of a molded article and an apparatus for implementing the method

There is disclosed a method for controlling a fill speed of an injection unit, the method executable in a computing apparatus configured to control a plunger actuator of the injection unit. The method comprises receiving an indication of a mold-cavity-filling parameter, the mold-cavity-filling parameter being indicative of a number of molding cavities of a multi-cavity mold having been filled; responsive to the mold-cavity-filling parameter satisfying a pre-determined threshold, releasing a control signal to the plunger actuator to control speed associated with a plunger of the injection unit from a first filling speed to a second filling speed.

Method for controlling fill speed in a molding system

An injection molding machine is provided, including a nozzle assembly having a channel for conveying a fluid. At least one cavity insert is removably mounted within a cavity plate, the at least one cavity insert defining a mold cavity, and a first portion of a gate for communicating the fluid between the nozzle assembly and the mold cavity.
