My first injection mold and the Rabit HY-4 injection molder

[gavztheouch]

Good spot deisel most probably is the same machine, I didn't actually win the auction but the winner went awol and I was the secound highest bidder so I thought I would take a punt and accepted the secound chance offer. Its 240v for the heater and logic controller and 3 phase for the hydraulics. Took me a while to figure out how to wire it all up as the 240v supply was cut off inside the controller and I had the hydraulic pump motor spinning the wrong way. Seems to cycle ok now, there is even a small air cyclinder that activates the ejector pins and a light gate to sense wether parts have stopped exiting the machine. All in all pretty pleased but if I find Im not up to making a mold or have no need for the machine Ill let you know and maybe I can pass it on to you.

What is the easist material/plasic to use in an molder like this. I would like to get some granulated plastic purged through the nossel, before I commit to making a mold.

Looks great but with a name like 'Rabit Hy-4' you'd better watch out for vibration
