GRIT BLASTING – A Precision Engineering Tool of 21st Century

Grit blasting is a process in which abrasive particles are pneumatically accelerated and forcefully directed against a surface. These high speed abrasive particles remove contaminations from the surface of the material and recondition the surface for subsequent finishing.

Historically, the material used for artificial sandblasting in precision engineering was sand that had been collected in a uniform size. The silica dust produced in the sandblasting process caused silicosis after constant inhalation of dust.

According to the new grit blasting process used to clean the residual sand from castings the precision engineering company blow air at high velocity lead shots or sand to clean the castings. Procedure for cleaning of metal surfaces, for which fine silica sand is blasted through a nozzle onto the surface by means of compressed air to remove scale as well as other coverings.

There are a number of materials used in grit blasting some are: aluminum oxide, white aluminum oxide, corn cobs, crushed glass grit, glass beads, plastic abrasives, pumice, silicon carbide, steel grit, steel shot and walnut shells. Lone Star LWD employs the best methods and materials for grit blasting that end up in complete satisfaction of client’s requirements.

Here are some of grit blasting applications are listed below in order to have the best quality precision engineering services

• Roughening surfaces in preparation for thermal spraying, painting, bonding or other coating operations
• Removal of rust, scale, sand, or paint
• Removal of burrs
• Provides a lusterless surface finish
• Removes flash from molded components
• Aesthetic surface development or design
