A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.

A system is disclosed for micro-molding articles. The system melts and pre-pressurizes thermoplastic material to a first level, within a plasticizing barrel. The melt pressure of the thermoplastic material is manipulated to a second level, within a hot runner. The melt pressure of the thermoplastic material is manipulated to an ultra-cavity packing pressure within a valve gate nozzle.

The present disclosure provides a method of adjusting a dimension of a molded product. The method includes generating a plurality of adjusted molding conditions comprising an adjusted velocity profile and an adjusted packing pressure profile; conducting, via an injection-molding apparatus, an actual molding to produce a molded product using the adjusted molding conditions if the adjusted molding condition is qualified; determining whether a dimension of the molded product needs to be adjusted; and updating at least one of the adjusted molding conditions if the dimension of the molded product needs to be adjusted.

A plasticizing device that plasticizes a material and includes a drive motor, a screw that is rotated by the drive motor and that has a grooved face provided with a groove, a barrel that has an opposed face opposed to the grooved face and that includes a communication hole communicating with the groove at the opposed face, a heating section that heats the material supplied to the groove, a first temperature sensor that measures a temperature of the groove, and a control unit that controls the drive motor, wherein the control unit performs a first process for rotating the screw at a first rotation speed when a temperature measured by the first temperature sensor is a first temperature, and a second process for rotating the screw at a second rotation speed lower than the first rotation speed when a second measured temperature measured is higher than the first temperature.

An apparatus for controlling the rate of flow of a fluid mold material comprising: a manifold, an actuator interconnected to a valve pin, a position sensor that senses position of the valve pin, a controller that controls movement of the actuator according to instructions that instruct the actuator to drive the valve pin upstream at one or more selected intermediate velocities in response to receipt by the controller of a signal from the position sensor that the valve pin is disposed in the one or more intermediate upstream gate open positions.

A remote controller can be provided on any apparatus that employs feedback control from a native controller to add functionality to the apparatus where the native controller is not capable of providing such functionality independently.

A hot runner device for an injection molding machine, wherein the hot runner device has at least one hot runner system, and at least one sensor, actuator and/or initiator which can be connected to a control and regulating device via one or more signal and/or data paths, in particular lines, wherein process data and/or process signals can be transmitted via the one or more signal and/or data lines, characterized in that the hot runner device further comprises a data acquisition and backup device which is designed at least for acquiring and storing part or all of the process data and/or signals acquired on the hot runner system during operation of the injection molding machine and which is a functionally integral component of the hot runner device.

A method for manufacturing a wind turbine blade, including the step of monitoring a process of infusing and/or curing a fiber lay-up with resin in a mold, wherein the monitoring is based on sensor data obtained from the resin infusion and/or curing process displayed in an augmented reality device, is provided. Displaying sensor data obtained from the resin infusion and/or curing process in an augmented reality device allows to better monitor the resin infusion and/or curing process. Thus, the quality of the manufactured wind turbine blade can be improved.

A method and apparatus for performing an injection molding cycle comprising drivably interconnecting a valve pin to an electric motor actuator and controllably operating the electric motor to drive the valve pin at one or more reduced rates of upstream or downstream travel based on either detection of the position of the pin or actuator or on a preselected length of time at which to drive the valve pin.

Injection molding apparatuses and methods wherein a valve pin is controllably driven upstream and downstream along an axis between a first closed position where the tip end of the valve pin obstructs the gate to prevent the injection fluid from flowing into the cavity, a full open position and one or more intermediate positions, wherein the valve pin is drivable to be disposed or held in a selected intermediate position for a selected period of time during the course of an injection cycle where the tip end of the valve pin restricts flow of injection fluid through the gate to the mold cavity.
