The first industry test moulds were successfully done in a rather stiff plastic and looked very nice. Now it turned out to be tremendous problems squirting in the elastic material needed. I was forced to quickly approve a costly remake of the plastic injection tool testing a theory of increasing intakes from 4 to 10 would make it work.
Adjusting one thing changes another. At least it did work, they got the troublesome rubber into the mould but this presented new problems. It didn’t work to just rip of the casting beard. I had to individually cut off ten strings from each casting beard from over 5.000 units =50.000 cuts! This meant hours of extra work on top of my stupid paper sheet packaging solution adding even more time to the task.
Even with the massive casting beard they had to push in the rubber at maximum pressure. This led to lots of residue left on the products, especially from the casting beards. If you didn’t cut it properly, or even worse, ripped off the casting beard there would be a considerable amount of plastic crap hanging out. This was certainly not good enough and I had to trim the inside with a nail clipper. Not a thing you want to do 50.000 times when the deadline is only a few days away.
Now it was time to call in the big guys to sort this mess out.
