Wet Blasting engine parts
Looking for input on Vapour Blasting Technologies machines. Any comments would be appreciated. Thanks
Re: Wet Blasting engine parts
Most 'blasting' processes work reasonably well, if you use the right media and settings ...... I've used nearly all of them over the years like a lot of others
The trick of getting all the stuff back out every time is what trips people up, hence the drift in some cases to using soluble media, such as baking-soda, which you can't use in a wet blast cabinet
If you're blasting 'solid' objects, or at least ones that can be easily checked for media retention, it's less of a risk ....... anything more prone to be a trap is a greater risk, remaining media forced in under pressure can often release with subsequent heating/cooling cycles
If that happens, in say, a water jacket then it's unlikely to be catastrophic, elsewhere could be a very different matter
So I guess I'm saying it's sometimes more of a case of what you are blasting as much as what you're blasting it with

Granted, the cleaning the entire blasted part is different than trying to mask off all the holes in an open engine.
But GM is mighty concerned about the debris from those surface conditioning disks.

I did a demo of one of these machines at IMTS. I was not impressed. There is so much water flow it is difficult to see and I didn't get the impression this would remove stubborn carbon, but perhaps with the right media it would. I prefer the old standby, glass beads. I then clean the parts well in an aqueous cleaner before they are sent.

I was very interested at first also but it's far more complex and it takes a lot more HP to do the same thing as dry blasting.
You can get more advanced with dry blasting and get the same or better results IMO, It would be nice to have two or three blasting cabinets each set up with different media, could share the same dust collector.
Pressure washer in a cabinet might be a great way to clean parts without getting wet tho.
