About bead blasting (sandblasting)
The technology is the process, of forcing solid particles across a surface at high speeds. This metal, wooden, plastic or glass surface becomes thinner, which otherwise would be damaging, but in this case, it is our main objective. During this process, the contamination on the surface of metal, wooden, plastic or glass objects will peel off. We get a smoother and cleaner surface, as a result of which the objects can be re-painted and renovated.
The most important factors when an object is being cleaned:
- The right choice of the blasting material
- The optimization of the impact time
- The precise setting of pressure
During an average blasting, 20 - 60 μm is peeled off from the surface, which does not change the size of the object significantly. Of course, with objects that require a working of higher precision, it is possible to realize a finer cutting. Usually we use this technology for cleaning the surface of steel structures; moreover, surface cleaning is becoming more and more widespread for the fashionable and practical stainless steel objects.
You have to take account of the fact that bead blasting (sandblasting) is not a cheap technology. However, so far it has not been replaced by other, more effective technologies with respect to price, quality and productivity. In Technology and Tips, you can read about the factors which influence the price and efficiency.
