Heres todays gloat. Mitsubishi injection molding machine. $300. Dont work but dont care. The place it came out of had problems with it and didnt repair it as the other machine they had was enough for what they wanted.

I got it got it for the parts. 4 Mitsubishi servos. 2 - 1KW motors and drives, 1 2KW motor and drive, and one 5kw motor and drive. Plus all sorts of other goodies. Not sure what the motors take for an input. Will have to look them up tomorrow.

Yeah, yeah, that's cool and all... But tell us more about that confetti-gun/potato-cannon/T-shirt-gun/Stalin's-Organ battlebot in the background. :D

I will give you $400 for it. :D

Odds are I know how to fix it. Put it back together and slap a UPS tag on it and get it to me ASAP. :p

But seriously, what are the symptoms? Give me as much info as you have on it.

Yea seriously, If I had the room and $600, Id give you $600 for it as is, and pick it up my self. :eek:

I love that kinda stuff, would be worth $300 just for the fun of tearing it apart :D

Although I'm with Liger, don't be too quick to rip it !

It's definitely cool, and you ought to get it working but...

Doc is right...

We want more on the Katyusha-Spud-Gun-Of-Doom!

The thing in the back is a 9 barreled t-shirt launcher. The rover under it was built by my boss as a battlebot but they went under before that happened. I will get some pics later. The launcher was built with the kids in the robotics program at Tigard High School. I was debugging it till 1 in the morning when on the day they were supposed to bring it to PGE Park in Portland for the Beavers game.

As for the injection molder it is incomplete and the previous owners gave up on it. Plus at 105 amp three phase 240 it would be a killer to run. And then there is the missing parts and tooling needed. I could dump money in those parts and still not get it working. Then I need dies, feed stock, dryers, chillers, etc.

Injection mold machines are really a dime a dozen in this economy.

The servo drives are the ones I hoped they would be. They have step and direction inputs so I can interface them to just about anything. Think I may make a press from the toggle system.

Oh yeah, one other thing about this machine. It is a Japanese machine intended for use in Japan. The company that owned it was Japanese and it was pretty common for them to ship equipment over from Japan that is not available here normally. I have gotten several pieces of equipment from them and old Japanese stuff is poorly supported, if at all. I got a real nice A3Wide color laser printer from them and to get toner carts that fit without modification I would have to order through a retailer in Japan. Also my Tsugami tool grinder is one of probably only a could in the US.

Dime a dozen for molding machines? I wish! I have $10 in my pocket. *sigh* :p

Well, if it's incomplete then it's dead. 'tis a shame because I've run that sort before and those be NICE machines. Not as good as a Milicron Roboshot but still decent.

But for future reference you can run HDPE, Polypropylene and Delrin without drying... and really for non-precision work you can get away with circulating cold water through the mold. Big old poly tank, small circulating water pump and some hoses/fittings. Truck radiator and fan makes a good heat exchanger and if you need "warm" water tie in a small hot-water-heater and a three-way mixing valve.

My friend Roy Goddwin (seriously) has two old 80's vintage Milicrons in a barn that he runs from time to time using a arrangement like that I'm his Setup And Programmer Dood. :)

One thing to note though Delirn can be dangerous in uninformed hands. Clouds of corrosive death, explosive mixtures of vapor and stuff like that. Molten Delrin is a totally different "beast" than the stock you machine.

And as for molds... You're setting up a machine shop, eh. You can BUILD molds. :)
