Sandblasting uses air pressure and materials to clean and prepare metal surfaces. A blasting system includes an air source, blast cabinet, dust collector, and blasting medium. Sandblast cabinets come in various sizes and designs for different jobs, and some have built-in units for convenience. Safety is important when using blast cabinets.
Sandblasting is the use of air pressure and a variety of materials to clean and prepare metal surfaces for repair, painting or welding. The materials used in sandblasting, whether sandblasted or not, are referred to as sandblasting media. Sandblasting can remove paint, rust and oxidation residues from materials quickly and efficiently. Sandblasting can also be used to change the surface condition of a metal, such as removing scratches or casting marks.
A blasting system comprises four basic components: the air source, the blast cabinet, the dust collector, and the blasting medium. The air source is usually a gas cylinder or an air compressor. The blast cabinet holds the object to be blasted, while the dust collector removes the powder from the cabinet.
There are two basic types of blast cabinets that the user can choose from: the portable tank blast cabinet and the can blast cabinet. The sandblasting cabinet for cylinders is the more basic model and, therefore, the cheaper of the two.
Sandblast cabinets can be purchased in all shapes and sizes. The front, top and end load designs are all used for different types of jobs. You can also purchase a blast cabinet with a horizontal, vertical, or 45 degree viewing window to suit the type of material you are blasting. A different view is needed, for example, when sandblasting car parts versus wood projects.
A sandblasting cabinet can also have a flat bottom or rest on a work surface. This type of sandblasting cabinet is used for small jobs. There are, however, a few types of cabinets called “V” bottom cabinets, which have legs and can be used for larger projects that are too large to complete on a tabletop.
A smaller blast cabinet might be used for jobs like coffee mugs or trophies. These items are quite delicate and require more control over the sandblasting process. Many rock harvesters also use medium sized blasting booths to blast and polish the rocks. A large sandblast cabinet could be used for flat glass windows, shower doors, or door inserts.
There are some cabinets that have built-in blasting units. This makes using the sandblasting cabinet more comfortable and is ideal for large jobs. Still others have built-in dust collection systems, making cleaning easier. The advantage of this type of blast cabinet is the ability to do more work at once, because you don’t have to spend time dealing with dust cleaning.
A sandblast cabinet generally comes with rubber sleeves and gloves attached, which help prevent accidents. Safety is an issue with blast cabinets when they are misused because the blasting materials move at very high speeds.
