although I don't own this specific book, the gingery books I have are pretty great. https://gingerybookstore.com/InjectionMoldingMachine.html https://gingerybookstore.com/InjectionMoldingMachine.html if you've got time and space, you can do way cheaper than $10k. You need a drill press and a metal lathe. If you're feeling ambitious, there are other books that will show you how to build a drill press and metal lathe. Really depends on how committed you are to bootstrapping and saving nickels.
