Build an Injection Molding Machine From a Cheap Pneumatic Press

Look I’m using the ubiquitous “person with white outline“ thumbnail! I got a cheap imported 500kg pneumatic punch press and converted it to do injection molding. The heating chamber came from @BusterBeagle3D’s V2 Injection Molding machine. The press provides a ridged frame, the pneumatic cylinder, an electronic controller, solenoid valve, regulator, plumbing, etc. All I had to do was add a heating chamber and a clamping system for the dies. Final shot size is 13grams (1 cubic inch) and it’s delivered at up to 2500 psi. A similar AB-100 Injection molding machine has a 6g shot size at 6333 psi. Here’s a detailed cost breakdown and source links for various parts (including tax and shipping!) Press: $ Punch Press&_sacat=0 (Seen as low as $310) Heating Chamber: $
