Low Volume Production Manufacturing (CNC Machining, Silicone Molding)
Prototyping < Low volume quantity (It is a bridge and supplement from prototype machining to mass production)< mass production
So if you want some small quantity to confrim the design of testing again , will good choose , becasue the unit price will lower than prototype . we will choose good processing to do it .
For low volume , usually CNC machining and Vacuum casting will better .
CNC : we only to debug machine one time , then made it . for silicone molding , usully 1 mold can make 10pcs products , so cheap cost .
