Hi Dualkit
The part is around a 8cent to 11cent part molded depending on material cost,You don't build a complete mold on a job like this, you use an old mold & just put some cavitys in it,this is quite fast to do on a simple part like this was, but you do need to add your machining cost of the mold to that price, Cycle time 15sec to 28sec for 5 pieces, so around 10 pieces per min
