Sand Blasting & Painting
Ideas IT Ltd. specializes in Sand Blasting and Painting. Our Sand Blasting & Painting services enhance the physical properties, wear resistance, adhesion, scratch resistance, wet ability as well as the external appearance of the components.
Traditional wet painting involves a solvent-based or water-based paint being sprayed onto a surface.The blast and paint technique is more intensive and can be broken down into 3 steps: pretreatment, application, and curing.
Beginning with blasting, the surface of the part is cleaned (grease, previous coatings, dust or rust is removed) through abrasion. The etching and scratching in the surface prepares the surface so that the paint bonds and sticks with it. Without this step, paint chips more easily. Sandblasting strips the oxidation off of the steel. Leaving it exposed and not properly finished in the wrong environment will cause rust to form quickly. The part is allowed to dry in a safe atmosphere before the next step.
The Advantages of Sandblasting and Painting
The main benefits of the former are durability and longevity. Blast and paint does more than provide a pretty paint job:
Corrosion: At only 3 mils, a single coat has similar corrosion protection to that of 3 coats of paint applied at the exact same thickness.
Economical: As a solid product, wasted spray can be reclaimed and reused. Overspray is less likely and the transfer efficiency of blast and paint is between 60 and 70 percent
Production Benefits: Blast and paint gets parts ready to go faster than wet paint. As soon as a chassis is cooled it is ready to be handled or machined further.
Chemical Resistance:With blast and paint the finish is chemical resistant. Just wipe up the mess and the paint is left unscathed.
Sandblasting
Sandblasting or bead blasting is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but provides a more even finish with no problems at corners or crannies.
