Embossing roller processing method of sandblasting

Date:2017-05-04 Author: Click:

Sandblasting is the use of compressed air as the driving force to form a high-speed jet beam will spray (shot glass beads, steel balls, steel sand, quartz sand, emery, iron sand, sea sand) high-speed jet to be processed surface, The mechanical properties of the surface of the surface changes, due to the impact of the abrasive surface of the workpiece and cutting the workpiece surface to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface is improved, thus increasing the workpiece Of the anti-fatigue, increasing the adhesion between it and the coating to extend the durability of the coating, but also conducive to the leveling and decoration of the paint, the surface impurities, variegated and oxide removed, while the media Surface coarsening, the substrate surface residual stress and improve the role of the substrate surface hardness. Embossing roll


Embossing roll

One of the methods of making the roll - the etching process is a chemical surface treatment method that sometimes causes the appearance of the finished product,

And sandblasting is a physical method to solve the chemical method is difficult to solve the problem.

It can be divided into:

(1) full gloss (100%): glass sand

(2) semi-gloss (50%): 50% glass + 50% gold grit

(3) Matte (0%): gold steel sand (alumina sand)

It is difficult to completely adjust the gloss of the resin material by the difference between the resin material and the injection molding conditions. Therefore, it is necessary to repeat the application several times.
