Home injection molding part 3: Making stuff! (kind of..)

Check out my 2nd channel, TT Racing: @ttracingYT It’s time for some home based injection molding. I’ve had this machine since 2014, but it has been sitting idle for a while now, due to an error on my part. Previously, I attempted to mold some bespoke silicone washers to seal the machine, and did manage to mill a two part aluminium mold ready for recycled plastic. In this video, I make some further repairs and alterations and finally put through some shredded PLA with frustrating results. Is it worth more modifications and testing? At the moment, I think not. Please note that this machine is sold to suit 110V mains voltage. In Australia we use 220V, and I’m pretty sure I removed one heater and converted the other. If you also use 220V, you would need to do the same or use a step down converter. It’s also worth noting that this machine was never intended to be used with this type of plastic. If I were to stick to the original Plastisol material, it would likely have been flawless. 0:00 Introduction 0:42 Recap Part 1: Part 2: 2:09 Silicone o-rings (again) 2:50 New PID controller (with autotune!)
