Injection Molding DIY

One of my projects requires some plastic injection molded parts. Quotes for the molds came in around $15,000 which was way over budget for prototype parts. My solution was to build an injection molding machine to mount on my arbor press. I tested the machine with a simple spinning top mold before attempting to make the more complex molds for my original project. I used a cheap PID temperature controller, two 300 watt elements and a thermocouple. To use, I just set the desired temperature, drop in some plastic pellets or recycled parts, and press the melted thermoplastic into a mold.

Although I didn't follow his plans, it was a great resource to get started: http://amzn.to/2uKYJSc
