    摘要： A method of monitoring and controlling a molding clamping apparatus in an injection molding or other molding process is disclosed. The method includes creating a target strain profile, receiving a deviation limit, receiving a change in strain relating to a mold while it is closing from a first strain gauge, identifying a deviation from a target strain profile based on the output from the first strain gauge, determining that the deviation exceeds the deviation limit, and adjusting the rate or force of clamp movement. The target strain profile may have a first portion relating to a clamp closing process, a second portion relating to a filling process, and a third portion relating to a clamp opening process. The first portion relating to the clamp closing process may include an intermediate portion relating to a coining process having an intermediate clamp force setpoint.

    摘要： In order to reduce oscillations in process variables of an injection molding process, a variable-gain proportional-integral-derivative (PID) controller is utilized to control one or more of the process variables. The injection molding system may also include a tuning controller to automatically tune at least one of the proportional, integral, or derivative gains within a mold cycle. The tuning controller may obtain sensor data that monitors the operation of the injection molding machine to determine an adjustment to at least one of the proportional, integral, or derivative gains. The tuning controller may adjust the gains of the variable-gain PID controller in accordance with the determined adjustment to the at least one of the proportional, integral, or derivative gains.

    摘要： A nozzle assembly for an injection molding system has a nozzle adapter with one or more vent holes therein. A porous metal insert is provided in fluid communication with at least one of the vent holes. The porous metal insert is also in fluid communication with a flow channel through the nozzle assembly. As molten polymeric material advances through the flow channel from a barrel to a mold assembly, gases entrained in the molten polymeric material are vented through the porous metal insert and escape through the one or more vent holes. Pressurized air may be introduced through the vent holes, such as by one or more blow-back modules, to unclog pores of the one or more porous metal inserts between shots of the injection molding system.
