About four months ago I started development of a new part, to make a better and cheaper alternative to an OEM piece. Paid for a custom injection mold, had a trial run and one subsequent adjustment to the mold, and then a production run of 2,500 pieces that got finished yesterday. I drove to the manufacturer this morning to pick up 20 boxes of parts. Not five minutes from the plant a customer called, one I haven't heard from in over a year, and asked if I sold that part. "Funny you ask!"
Now I just need to sell about 2,200 more to break even on the mold and the first run of parts.
