We’ve been using Rigid10K for injection moulding prototyping, this has been very effective so far.
But the parts are always slightly warped and our solution until this point is sanding the sides back 0.02 - 0.10 mm with 500/1000 grid sandpaper, to make the parts fit the mould housing.
Because we’re doing more and more iterations, the amount of sanding has gone up exponentially. We’re using PPE, but dust get everywhere…
My question, would a normal dust extraction system be sufficient (dust category wise) with the added glass in the resin? or does anyone have a other suggestion for this issue?
Simplest solution I can think of is to wet sand the parts if possible to help prevent the dust in the first place. As for dust extraction, I don’t expect that the glass fill would produce substantially larger particles to the point where sanded particulate would be extractable but glass fill would not be.
@barreax2 Wet sanding is a great option, didn’t think about that.
With the dust extraction I was aiming on the glass particles being smaller than a standard wood dust filtration system filter and thus blowing the glass dust into the room instead of catching it.
@MattRForerunner I did look at a downdraft table, it looks like a very good solution. What type of filter do you use?
