PPD Tech, LLC - Product & Process Development

Melt Tracker™
Melt Tracker™ technology provides process development and validation tools. We offer unique direct contact thermal sensors based on a patented microbead sensor as well as the hardware to benefit from their millisecond response time.
The toolbox:

	Micro Bead Sensors® Ejector pins with integrated thermal sensors
		Swap out standard ejector pins with thermal sensor pins
		Micro bead design with millisecond response time
		Test different locations; Optimize location and process
		Temporary installation or use in production monitoring
		Alternative: Install anywhere as stationary pins
		Custom thermal sensor core pins available
	Vent Sensors:
		Simple, non invasive, detection of end of fill
		Install in Vent relief channel
		End of fill and short shot detection
		Temporary ‘Development’ or ‘Production’ versions available
	Nozzle Sensors
		Characterize Complete Cycle Profile
			Injection / Hold /Screw Recovery
		Integrated Temperature and Pressure Profile


Shot Spot®, with Process Windows, fingerprints process stability. Shot Spot’ fingerprints the process by capturing critical “Peak Temp” or “Peak Pressure” Values and “Time to Peak” for each shot for any selected channels. Sees ‘Process drift’ before it is a quality problem.

Melt Tracker® Process Monitoring Systems; available for PC, laptops or shop floor systems.
	Monitor Flow and Melt Fronts with millisecond resolution:
		Nozzle, Cavity Pins, Vents, Pressure transducers
			Peak Temps and Time to Peak Temps
			Capture actual Fill Times by cavity;
				Monitor /alarm on any variations:
				Cavity to Cavity
				Gate to End of Fill
				Start of Injection to End of Fill
		Quickly see cavity filling variation from any changes in Process conditions, material or external factors
		Establish Process Window based on real-time Melt Front data
	Short shot detection. From Cavity or Vent data
	Simple historical analysis:
		Data from each shot is time stamped and saved
		Historical process data easily accessed by:
			Melt Tracker, Excel or any statistical analysis tool
	Trigger DAQ, based on Temp value or machine digital output such as Injection Start signal
	Integrate Temperature and Pressure data
		Any Thermocouple type
		Any standard analog or digital signal
	8, 16, 24 or more channels
	Analog or digital input / outputs
