jamesinc So the mould represents $1/unit, understood!
$0.50 per unit because large mold and your doing a pair per injection cycle
I think you might be able to get aluminum molds made using CNC instead of EDR... for around 10-15k
they would be good for ~1000 units
so assume $20 per pair and they look mostly "ok"
actual injection molding with ABS would increase price to around $50 per pair
so $50k investment, have 950pairs (5% reject rate) and then you need to sell all of them
IMHO $250 pair is over the top... but I think I would want to be running a minimum 50% profit margin because risk... so I'd be doning $100 pair... and how many am I going to be able to sell at $100 pair?
