This is the design surface needed , but before start. This surface need to be designed for core and Cavity and motion simulation, also design of the mould parameters (runners, gates, mold base, cooling channels, etc.).
If you have done this before it should not take too much time. I would like you to send me mold design with core and cavity before start
would you please send IGS or stp file format to me? can I use Creo to build your core?
by the way I have small injection mold shop. if you have interesting . then we can cooperate for this
