Injection Molding 3000 ton Kraus Maffi after a new control System was Installed

[cjsobo]

I work in a small custom shop, our largest machione is a 300 ton Van Dorn. How do they pull the mold in this thing? With a crane?

hmmm in england your supposed to turn off the pump motor before you enter the mould area but how are you going to run the machine in semi like this vid and still keep production happy with the output of product.

This krauss is not killing the pump because in the time he gets out and presses go there no way the pump would charge the accumilators so its all very contradictory.

Nice machine, I always loved Krauss machines. For those who crying about walking into machine... Even smaller and cheaper machines are redundantly protected, thus making impossible to move the clamp when gates opened. Impossible! Due this fact, I never seen accidents caused by a machine with working safety gates. And sometimes robots can't do things in certain conditions.

Shiiiitttt!!!!! I would NEVER let anyone walk in a machine like that, without shutting the motor down. We have robots on all our machines.

[arliebarlie]

nice machine but rubbish process - have to agree with andalux - no WAY would i get in or allow anyone to remove parts like that!!

Krauss= juke!

[R3BB3LX]

its Krauss Maffei not kraus maffi.

i hope you guys where just testing the new system in this vid and not axially considering production in this manner, just saying that you would lose to much profit producing the parts like that.

I agree Andalux. We have an all servo robot for sale that came off a 3000 ton Milacron machine if you are interested

I wouldn't walk into that platen for US$5000 a day. I don't care if you had 2 dozen safety switches on it.

[magurk1]

Under the Platens is a redundantly wired platform that will open the dump valve on the hydraulics and also kill The pump if it sees a gate close Signal. And while you are in the platen area to remove a part the hyraulics are totaly unloaded ,if you are standing on the plate which covers the whole base inside the machine.

[Andaluxsystems]

Ok got you, perhaps I should congratulate you on the succesful retrofit of the control system, I was in simillar situation on a small Arburg, since it was a very old machine, I ended up fitting a cheap Chinese PLC and it worked just fine.

@magurk1 it´s a job, u wet pussy

[m10gpx]

@magurk1 i agree. providing ALL mantainance progammes are completed honestly and thoroughly.

On most machines i've set up , there is a machanical dump valve, operated when the safety gate on operator side is opened, which dumps all pressure back to tank. I'd do the job no problem, only if i'd done saftey checks myself

@Andaluxsystems Note the safety ratchet on the top bar + low pressure close till mold protection scwithes to high
