Custom Cartridge Heaters For Beverage ManufacturingA major beverage manufacturer used several large fill and seal lines to manufacture drink pouches. However, the production lines were encountering problems with cartridge heater failures on the sealing dies, thus causing them to shut down. This, in turn, resulted in a large loss of revenue. Time to look for a new cartridge heater supplier.Durex Industries’ engineering team investigated the situation and discovered that the cartridge heater leads were weakening and breaking due to the rapid movement of the sealing head and vibration found in the equipment. We recommended a switch from pin leads to swaged-in flexible leads. In addition to further remove stresses and strains from the lead wire to the connection point of the electric cartridge heater, we also suggested they affix the leads in a stress-relieved configuration. The beverage manufacturer implemented our recommendations and new custom cartridge heater design, which resulted in the elimination of the premature heater failures, significantly reducing equipment downtime issues and loss of revenue.
