Glass blasting process and satin plating
October 1, 2009
Q. Dear Sir,
I want to know about glass blasting process.
Is it similar to sand blasting or what is the difference between these two?
On which components we should do glass blasting process?

A. Well you are saying (glass blasting) so I'll assume that you are using compressed air. Sand blasting and bead blasting or glass blasting are all done more or less the same way.

Steel blasting for shiny resultNovember 17, 2018
Which way of blasting is best for shine on steel (I don't know, does that exactly mean shiny, when say satin?)
Is the glass beads the best choice?
Does pressure have to be higher or lower?
And beads, smaller or higher?
Any more effective way for shiny finishing?

A. Hi Mirko. Yes, glass beads are often used for a satin finish. They are very small and leave very tiny indentations in the finish to give it a clean but matte look. But even when people clearly understand what they mean by satin finish, disputes are a commonplace. If you don't know exactly what the customer means & wants there is little chance of successfully meeting their expectations. They have to point you to a sample, not try to describe it in vague words :-(
A bright mirror-like finish is achieved by polishing & buffing, using a series of ever-finer abrasives and softer wheels, rather than by blasting. But plain steel won't long retain even a matte shine, and I doubt that it can actually be mirror polished in the first place, let alone retain the mirror finish for long :-)

Q. Hello Ted, thank you for reply.
I use to work with different wheels on a grinder and I can achieve shiny steel that way. Now I got a lot of work and trying to find similar result with blasting, to save my time. I'm a bit disappointed, I thought that blasting with glass beads would do the job.
Is there a way to turn sandblasted steel (blasted with sand) from dull gray to shiny metal? Any paste or ...?

A. One thing that may help us is what is the size of the part, configuration, and metal? Blasting systems are usually used on large parts above 6x6", There are 5 basic surface modification systems. Need to know more.
