Abstract
An extrusion control system for use with one or more extruders has a data acquisition module in communication with one or more data acquisition nodes that are associated with an extrusion process. A control module is also in communication with one or more control nodes associated the extrusion process. A synchronization signal to one or more control nodes causes the nodes to adjust to a predetermined setting.
Claims20
A method of producing an extruded article comprised of a plurality of extruded parts, the method comprising:
- defining a part profile;
- associating a plurality of control parameters with the part profile, wherein each control parameter has an initial value;
- producing a first extruded part using the plurality of control parameters in a closed loop system;
- resetting each of the plurality of control parameters to its initial value;
- and
- producing a second extruded part using the plurality of control parameters in a closed-loop control system.
The method of claim 7, wherein the substantially repeating period is a function of the length of the extruded part.
A method of producing an extruded article comprised of a plurality of extruded parts, the method comprising:
