Heat Seal Packaging Equipment

 

----Straight Armor Cable Leads.jpgThe Challenge: A manufacturer of heat seal packaging equipment was having problems with consistent, repeatable temperature uniformity on their sealing bars. This resulted in poor seal quality and impacted customer satisfaction with the equipment.

Our Solution: We were called in to aid in finding a solution to the problem. We performed a radiographic examination of the competitive heaters, as well as dissected them to determine possible reasons for the lack of uniformity. Although the long cartridge heaters used in the seal bar had distributed wattage (to attempt to minimize cold ends on the seal bar), the wattage distribution was not matched to the profile of the seal bar. Therefore, there were areas on the bar which were too cool. When the temperature of the seal bar was increased, the other areas of the bar became too hot. We developed a modified "multi-step" distributed wattage profile in which the proper wattage distribution was "tuned" to the seal bar, thus eliminating the uneven heating which was causing the sealing problems.

The Results: Switching to the Durex solution eliminated the seal quality issues and greatly increase customer satisfaction with the manufacturer's packaging equipment.
