Tank-free, FIFO melt-on-demand design exists specifically to eliminate charring and thermal shock — the failure mode a tanked hot-melt system develops when adhesive sits at melt temperature through extended idle periods.
Charring and thermal shock are real failure modes of tanked hot-melt systems that hold adhesive at temperature during idle periods on a case-sealing line. InvisiPac's melt-on-demand, tank-free design is built specifically against that failure, and the 10-minute startup is what makes a shift-start or changeover practical without pre-heating a full tank.
