A Hot Air Station Case Study Using Thermal Imaging by AnC

AnC is a leader in the tube sealing industry developing badly needed instrumentation to help set and measure the various parameters of the tube sealing process. The attached photos and video show an AnC research lab evaluating new Hot Air Stations using a Flir Camera¹ for our AnC equipment line. We also find it helpful to evaluate new tube products and improve on existing OEM tooling.
The photos and video are used on the AnC Tube Sealer (TS-100).  The photo’s view is looking down into the tube from the top.  As shown in the photo below the tube is leaving the Hot Air Station and has heated the inside edge of the tube. Once heated it drops down into the sealing jaws and is sealed. Page 2 shows the tube leaving the Hot Air Station. The color pattern shows the remarkably uniform heat distribution on the top sealing edge of the tube. Page 3 shows the Sealing Jaws closing on the tube creating a perfect seal. The final page (page 4) shows the completed sealed tube leaving the sealing station. Again look at the consistent, uniform temperature of the sealed tube.

The Tube shown below has left the Hot Air Station and has evenly heated the top inside of the Tube. The red color is the inside of the tube and shows an even color indicating that the tube area to be sealed is at the required temperature. The outside of the tube is shown in green indicating the even heating leading to a perfect seal. This type and quality of seal is usually only seen on the most expensive production machines costing $100K’s.


The Tube now has moved into the Sealing Station. The Sealing Jaws have closed and have started the sealing cycle. All of AnC sealing machines provide complete electronic control of all sealing parameters. Once the jaws have closed for a specific time they will open and the tube will leave the station.

This last photo shows the Tube Leaving the Hot Air Sealing Station. The Jaws have opened and the Tube is dropping down and onto the conveyor line. Notice the even, consistent color of the sealed area of the tube.

¹ The Flir Systems, Inc. infrared imaging camera is a device that forms an image using infrared radiation instead of visible light. It allows you to discover temperature issues that can’t be seen by eye or a visible light camera. Actual temperatures and heat patterns are clearly identified by a range of colors. The brightest (hottest) parts of the image are white, intermediate temperatures are reds and yellows, and the darkest (coolest) are blues and black. An area displaying only one color indicates a uniform (unvarying) temperature.
