Melt Profiler™ VII System
Calculates key metrics that predict and document part quality
The Melt Profiler™ VII system can be used with up to seven Temp-Sense™ sensors. It measures melt temperature 157 times per second and utilizes that data to calculate three key metrics during each shot. These metrics are the Maximum Temperature (Te), the Viscosity Rise Integral (Vr) and the Power Factor (Pf), as illustrated below:
Matching known quality parts with their specific melt profile (i.e. curve) allows molders to use the Melt Profiler™ VII to predict and document part quality. The most unique and exciting characteristic of the Melt Profiler™ VII system is the Power Factor (Pf). This metric gives molders the ability to clearly see very small changes in part weight.
Below is an example of how the Melt Profiler™ VII’s Power Factor (Pf) can be used to control part quality. Notice how very recognizable changes in the Power Factor (Pf) can identify very small changes in part weight.
Short Shot: Weight = 1.090g, Power Factor (Pf) = 251.728
Near Full Part: Weight = 1.105g, Power Factor (Pf) = 402.75
Good Part: Weight = 1.110g, Power Factor (Pf) = 453.06
Minute differences in part weight are easily identified by very noticeable differences in the Power Factor (Pf).
In this case, there is only a 0.005 gram (0.4%) difference in part weight between a good part and a near full part, but there is a 50.31 (11.1%) difference in the Power Factor (Pf).
Based upon the data collected by the Melt Profiler™ VII on this particular part, the customer set the alarm range for the Power Factor (Pf) between 436F and 465F. All parts molded within this Power Factor (Pf) range were good.
The Melt Profiler™ VII System Includes:
Hardware w/inputs for up to 7 sensors
One Temp-Sense Sensor
And a CD that has the proprietary data logger software.
The customer must supply a window-based device for viewing. The customer is also responsible for machining the hole where the Temp-Sense Sensor will be located, which is typically in the nozzle body or end cap of the molding machine. Please give us a call before ordering, so we can determine if there is enough steel in the nozzle body or end cap for the sensor to be fitted correctly.
