It seems I need to produce quite a few DIY kits. The plan: Take a big box of part A's. Take 20 (or how many A's there happens to be in the kit, measuring by weight where sensible), throw those in a bag, close and label the bag. Repeat and end up with a box full of bags of A. Repeat for C, D, E,... Then, take one bag from each box to a kit box, tape close and repeat.
How can I make this easy? The size of the job is too small to warrant buying a full automated machine. If I would be doing this constantly, it would make sense to drop 20-30k for such, but for a one-off project, no. But the job is big enough to spend some money for streamlining; each second on each bag is more than a day for the whole project. I' willing to spend a few thousand but not tens of thousands.
There has to be something between pure manual and big production machines. I'm thinking of a tool that takes plastic tube on and: Close handle, seals and cuts a bag; open handle, presents an open bag. Or something like that, but I haven't been able to find anything. Any hints?
For labeling the bags, I think I have to use laser printed sticker sheets, unless you have better ideas.
