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 that detects a flow front of fluid material flowing downstream through the mold cavity at a trigger location within the cavity disposed between the first gate and at least one selected downstream gate, a controller instructing an actuator associated with the downstream gates to open the gates at a predetermined open gate target time on a first injection cycle, 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 the predetermined open gate target time and the actual open gate time.

Injection molded articles and methods of making injection molded articles. The methods include the use of a first plasticizing unit and a second plasticizing unit on a common frame feeding a first mold and a second mold on the common frame. Separating the production of each part of a two-part article into separate plasticizers and molds allows for the tuning of production parameters on a per-part basis, improving part flatness and part-to-part weight variance.

An ultrasonic inspection system determines whether or not a thermally conductive resin forming a thermally conductive resin layer is filled through a waveform change of an ultrasonic wave measured by transmitting the ultrasonic wave toward a portion of an edge of a bottom surface of a module frame from the outside. An ultrasonic sensor at one of two opposite edges of an exterior surface of the bottom surface of the module frame determine a height of the resin within the battery module.

The invention relates to a method for process monitoring during production of a finished part (112) in a primary shaping process. The method comprises the following steps: a) providing at least one mould (114) designed for the primary shaping process, wherein the mould (114) has at least one cavity (116) for receiving at least one starting material for the hot-crosslinking material, and wherein an apparatus for determining a mould internal pressure is also integrated into the mould (114); b) heating the mould (114); c) introducing the at least one starting material for the hot-crosslinking material into the cavity (116) under pressure such that the finished part (112) is produced; d) detecting a progression of the mould internal pressure occurring in step c); e) differentiating, at least once or at least twice, the progression of the mould internal pressure in order to determine at least one derivative selected from the group consisting of: the first-order derivative and the second-order derivative; and f) characterising a progression of a chemical crosslinking reaction by means of at least one derivative selected from the group consisting of: the first-order derivative and the second-order derivative.
