Abstract
Apparatus and methods for storage and transmission of recipe data (process parameters) for the molding of articles in an injection molding apparatus. A controller includes a flow control microcontroller (MCU) that receives recipe data from a recipe storage microcontroller (MCU) mounted to a mold of an injection molding machine, the recipe storage MCU storing the recipe data defining process parameters for the molding of articles in the mold. The flow control MCU executes instructions for controlling valve pin motions according to the recipe data. In one embodiment, a human operator interface is provided for transmitting data to and/or from at least one of the recipe storage and flow control MCU's, allowing the operator to monitor, modify and/or control the process parameters during a molding cycle and/or to create a modified or new recipe for subsequent storage on the recipe storage MCU.
