I am working on a product with a very limited budget. I am trying to create some plastic injection prototype parts and hopefully up to 500 to 1000 initial parts to start my initial market introduction. My design of the part is completed and am ready to do the mold. I have a mold base, but need to find a way to mill the insert mold. I think I can use aluminum to keep it cheaper, but need advice on how to do this. Are there people on this site that would work with me to make a MUD mold for the two parts? Thanks to all for any input you might have.
