Abstract
Methods of monitoring and controlling a molding process using a sensed change in strain provided by a strain gauge are provided. A target strain profile is created for a molding process of a molding apparatus. An upper and lower deviation limit from the target strain profile for the molding process is provided. If a sensed change in strain exceeds a deviation limit, an alarm is activated.
Claims28
A method of monitoring and controlling a molding apparatus comprising:
- creating, by one or more processors, a target strain profile for a molding process of a molding apparatus;
- receiving, via an interface, an upper deviation limit and a lower deviation limit for the molding process;
- receiving, as an output from a strain gauge, a change in strain in the molding apparatus;
- identifying, by the one or more processors, a deviation from the target strain profile based on the change in strain received from the strain gauge;
- comparing, by the one or more processors, the deviation to the upper deviation limit or the lower deviation limit;
- and
- when the deviation exceeds the upper deviation limit or the lower deviation limit, activating, by the one or more processors, an alarm.
A non-transitory computer-readable storage medium storing processor-executable instructions, that, when executed, cause one or more processors to:
- create by one or more processors a target strain profile for a molding process of a molding apparatus;
- receive via an interface an upper deviation limit and a lower deviation limit for the molding process;
- receive as an output from a strain gauge a change in strain in the molding apparatus;
- identify with the one or more processors a deviation from the target strain profile based on the change in strain received from the strain gauge;
- compare by the one or more processors the deviation to the upper deviation limit or the lower deviation limit;
- and
- when the deviation exceeds the upper deviation limit or the lower deviation limit, activate an alarm by the one or more processors.
