I have an old Magma Mk 5 Bullet Master with upgraded pneumatics. That's the mould knockers and sprue knocker.
I'm struggling with the sprues sticking to the plate at especially 3 of the stations. At the other ones the knocker releases the sprues most of the time. When the sprue does not fall off at the right moment it stays on until the bullets are released when the knockers at 6 o clock station takes care of that, so it's really no harm done except a lot of sprues in the bullet bin. When casting 15000 bullets a day, that adds a lot of extra work.
On my machine the sprue knocker works together with pouring. The sprue knocker shoots out and stays on the sprue plate exactly as the pouring cykle runs on the top mould and the bullet knockers in the bottom runs their cykle. I can see that there may be a tiny misalignment at some of the mould positions because the knocker does not hit the sprue plate at exactly the same point at each station, but it's not much off.
My thoughts are that all of this is controlled by the pouring sensor under the pot and the misalignment can come from either the mould carrier arms or where they are attached to the wheel. It's not the mould mounting keys. I've measured them all, and they are the same.
A lot of rambling..... Are there easy fixes to this? Anyone?
One thing I have not tried are to adjust the psi setting on the machine. It looks like this is adjustable and it's currently set at 70 psi if the meter is right. How high can this be adjusted? This is the air pressure for the pouring and sprue knocker, right?
The bullet knockers in the bottom need about 125 psi, stated by the Magma manual, but if I understand this correctly they get the air preassure and their feed without going through the meter earlier described.
Thanks!
