Metal-fueled comps and star plates


greenlight

Recommended Posts

I have just purchased a star plate with delrin pins from calebs site for making perchlorate coloured stars mainly.

Most of the compositions I use have magnalium (I have 325 # MgAl) as the fuel and occasionally aluminium for glitter.

I have heard of people ruining their tooling from pressing metal containing mixtures.

Am i able to use fine powdered metal (325#) in the press or do I need to take precautionary methods each time like using a small amount of non-metal fueled comp in contact with the pins with each press?

Titanium and Ferro-Ti are all you really need to worry about. Spherical is the worst. Aluminum and mgal haven't given me a bit of trouble so far and I've pressed a bunch.

Thanks Oldmarine, I was getting worried since most of my colours contain MgAl.

Didnt want to ruin my new plate haha.

I think that is why they have the delrin(sp) pins, to allow pressing Al and MgAl comps?

Thanks greenlight for this question. I was ABOUT to ask the same, not as far as yesterday, when I pressed my first jopetes red stars with my plate. Now we know, thanks to OM as well
