Sand Media Blasters Alternative

Saturday, April 26th, 2008

Sometimes Sandblasting is a labor-intensive, hazardous process that typically is accomplished with a device that blasts sand particles, metal particles or other materials at selected areas of denim garments. The process usually must be done in a room that is shielded from other manufacturing areas, and the worker doing the sandblasting must wear protective gear to prevent being hit by or inhaling airborne sand or other particles.

But now a company called TechnoLines is unveiling its latest laser-scribing system, which features a patented method for creating a worn look typically associated with sandblasting.

This OH-based firm invented the TechnoBlast technology in 1997, and since then has worked to improve and protect the intellectual property rights related to its laser-based scribing process and the software system that drives it. Last year, the U.S. patent office issued three patents to TechnoLines related to TechnoBlast. As of press time, two additional patents had been granted, and several others were pending.

This system incorporates a software program for designing the desired worn look, and a computer-driven laser that simulates the sandblasting process. The designer can use the software to select the placement of a worn section; determine the degree and shape of the worn area; and create unique abrasion patterns to be scribed onto the denim garment in a matter of seconds. For example, TechnoBlast can be used to create the popular feathered abraded look, in which whisker-like lines are scribed onto certain parts of the garment to simulate a worn-in look.

Sandblasting Process

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.

Historically, the material used for artificial sandblasting was sand that had been sieved to a uniform size. Sand used to be the most commonly used material, but since silicosis (a lung disease) is caused by extended inhalation of the dust created by sand, other materials are now used in its place.

Other materials for sandblasting have been developed to be used instead of sand; for example, steel grit, steel shots, copper slag, glass beads (bead blasting), metal pellets, dry ice, garnet, powdered abrasives of various grades, powdered slag, and even ground coconut shells or corncobs, walnut shells, Baking Soda have been used for specific applications and can produce distinct surface finishes.
