Abstract
Disclosed are systems and methods for the use of a micro-bead EMF junction in the sensing and control of an injection molding process, whereby the improved junction is able to reliably sense and indicate temperature and pressure changes in a molding process.
Claims16
An injection molding system, including:
- a multi-variable sensor comprising dissimilar metals formed into a micro-bead junction;
- and
- a programmable device, with associated memory, connected to and receiving a signal from said sensor, said programmable device periodically receiving the signal and recording said signal to record changes in said signal, wherein said programmable device is capable of storing said signals as data.
An injection molding system, including:
- a multi-variable sensor wherein said multi-variable sensor includes a thermal-mechanical sensor having a micro-spherically shaped bead encapsulating an EMF junction comprising dissimilar metals formed into said micro-spherically shaped bead;
- and
- a programmable device, with associated memory, connected to and receiving a signal from said sensor, said programmable device periodically receiving the signal and recording said signal to record changes in said signal, wherein said programmable device is capable of storing said signals as data.
An injection molding system, including:
- a multi-variable sensor comprising dissimilar metals wherein said multi-variable sensor includes an EMF junction encapsulated within a micro-spherically shaped bead, said junction being suitable for sensing changes in at least the temperature and pressure of a surrounding environment;
- and
- a programmable device, with associated memory, connected to and receiving a signal from said sensor, said programmable device periodically receiving the signal and recording said signal to record changes in said signal, wherein said programmable device is capable of storing said signals as data.
