Hi, professors, I have a question how to cut the cost of 120°C composites tooling system.
the dimensional accuracy we hope will be ±0.5mm or ±0.2mm。the part what I want would be used in general industry: car,train,boat,sport,medical,plane,.....
I don't want to use tooling epoxy block to make the master mould, and also I dont want to use the epoxy Tooling prepregs to laminate the tooling.this tow metirials is too expensive and the process cost a lot.do we have any other choice?
