Verify you are using the proper modules on your glue applicator heads. Many packaging facilities I have visited have the incorrect modules for the specific application.
For example, I have seen zero cavity modules being used on trayformers, which is not needed and very costly. You can end up wasting money by using a module that is made for other types of applications.
We manufacture the many types of different modules: standard (276119) AO/SC and standard AO/AC, rebuilt EasyOn style (1048115), reduced cavity (replaces sure bead style), zero cavity, spray/swirl, ModPlus and others.
If you are unsure which module best fits your application needs, please do not hesitate to contact us. We are the experts and can guide you.
