Hi everyone,

I am working in a Wood company in Vietnam. We have a lot of manual operation for sanding, especially when our wood panel have curved edges or hardly accessible places (such as shapes etc). We mostly use MDF and not plain wood.

I am considering of buying a sand blaster. Nevertheless I think sand is to abrasive (unless pressure can be regulated and blasting radius chosen). Soda seems a better alternative but I think it will accumulate some residues on my panel right ? Basically I would like to use sand blasting instead of using manual operation with sand-paper.

Our process is the following :

Cutting with CNC
Raw sanding (manual and sometime automated for the top/bottom of panels)
Sealer
First layer paint (Spray painting, roller for top/bottom of panels)
Sanding
Second layer paint
Top coat

When using a blasting technology and MDF wood :
- is it appropriate to use it for the raw sanding ? (only for curves edges and hardly accessible places)
- Is it appropriate to use it for sanding after the first layer of paint (won't it remove it) ?

Thank you all, I ll keep you inform with my experiment,
