Injector blasting principle is the most common blasting technology
Blasting nozzle utilizes lots of compressed air
The injector blasting principle is a common blasting technology and basis of numerous systems by SIGG. Systems with high performance blasting nozzles for the surface treatment of small-sized objects, operating with the injector blasting principle, are widely deployed within a number of industries. Companies in the medical technology, electronics, electrical engineering, precision mechanics, as well as in the optics sector, refer to the injector blasting principle just as enterprises in the engineering, tool- and mold-making, dental technology or glass- and ceramic industries, as well as in the watch manufacturing. Craftsmen and restorers appreciate the injector blasting principle’s benefits just the same.
Injector blasting principle is as easy as cost-efficient
The injector blasting principle is equally easy and cost-efficient. An upstream air nozzle in the injector blast head generates high flow velocity. The resulting vacuum (suction) within the blast head mixing chamber, sucks the blasting abrasive through the mixing chamber of the injector blast head, transfers it through the immediately downstream blasting nozzle and blasts it onto the surface. Through the enormously high speed, the blasting material hereby unfolds the so-called abrasive effect. This process is commonly known under the general term „sand blasting technology“. The injector blasting principle is found again in manual blasting cabinets, blasting vessels and injector cup guns by SIGG Strahltechnik. Especially small-sized surfaces benefit from the injector blasting principle. However, it is also possible to deploy this technology for compressing stainless steel as surface finish, or, for example, processing aluminum.
Various blasting nozzles are applied
While operating with the injector blasting principle, various blasting nozzles are applied, having one thing in common: They need compressed air generated by a compressor, and, according to the application, a whole lot of it. The compressed air picks up the blasting abrasive, like glass beads, corundum, steel balls, brass powder, plastic granulate, or nut shells from a collection container and accelerates it. Finally, the blasting material combined with the air stream strikes the surface to be treated at high speed. Due to the blasting abrasive’s usually grinding effect, unwanted components of the surface, like rust or paint, are detached and removed.
Angle nozzles, flat-jet nozzles, wide-jet nozzles, or pipe-jet nozzles are utilized. The blasting nozzles differ from each other in the shape, which is either cylindrical or conical. The remaining used blasting material is, in case of a one-way blasting abrasive, either disposed, or, as a reusable blasting abrasive, recycled.
