Another aspect of Butyl that’s easy to overlook is designing and manufacturing the product for assembly, or DFA (Design-for-Assembly). One way you can improve your manufacturing efficiency is by switching from sheets to rolls.
Switching from sheets of 8-12 butyl foil patches to rolls of them. Sheets cause 2 assembly issues. First, the butyl will most likely stick to the sheet below, resulting in unnecessary time spent separating the two. The other problem is that the assembly worker will have to constantly stop after every 8-12 patches in order to grab the next one.
