Abstract
An injection molding system is disclosed. The injection molding system includes: a hot runner including: a plurality of heaters arranged into one or more defined heating zones within the hot runner; and at least one temperature sensor associated with each heating zone, and a system controller coupled to the plurality of heaters, the system controller being configured to: for each heating zone: determine a first control gain value associated with the heating zone; determine a total heater power of heaters associated with the heating zone; calculate a relative weight associated with the heating zone based on the first control gain value and the total heater power; and determine a zone type associated with the heating zone based on the relative weight.
Claims20
An injection molding system, comprising:
- a hot runner including:
- a plurality of heaters arranged into one or more defined heating zones within the hot runner;
- and
- at least one temperature sensor associated with each of the heating zones, and
- a system controller coupled to the plurality of heaters, the system controller being configured to:
- for each of the heating zones:
- determine a first control gain value associated with the heating zone;
- determine a total heater power of the respective heaters associated with the heating zone;
- calculate a relative weight associated with the heating zone based on the first control gain value and the total heater power;
- and
- determine a zone type associated with the heating zone based on the relative weight.
A processor-implemented method for operating an injection molding machine having a hot runner, the method comprising:
- for each of a plurality of defined heating zones within the hot runner having at least one temperature sensor associated therewith:
- determining a first control gain value associated with the heating zone;
- determining a total heater power of heaters associated with the heating zone;
- calculating a relative weight associated with the heating zone based on the first control gain value and the total heater power;
- and
- determining a zone type associated with the heating zone based on the relative weight.
