Restore and maintain the precision performance of your Hawo heat sealer with this genuine replacement lower heating cartridge.

The 6.536.028 Lower Heating Cartridge is a critical component designed specifically for the bottom sealing jaw of Hawo HPL WSZ and WVM constant heat sealer tongs. Over time, heating elements can degrade due to intensive use, leading to uneven heat distribution and compromised seal integrity. Replacing your cartridges ensures your machine maintains the consistent, high-temperature output required to seal heavy-duty foil laminates, coated papers, and multi-layered barrier films.

This spare part is manufactured to Hawo’s exacting German engineering standards, ensuring a perfect fit and long-term reliability for demanding industrial and medical packaging environments.
