sandblasting devices

Sandblasting is a complex technology that has also developed significantly in recent years. Accordingly, a large number of different sandblasting devices are used today - from small cup guns to large blasting vessels. Read in this article what sandblasting equipment is available and what you can use yourself.

Entry: the cup gun

The cup gun or sandblasting gun is the simplest device for sandblasting. It has a small suction cup, a pistol grip for triggering and a hose connection for a compressor.

The compressed air from the compressor pulls the abrasive into the cup with it. The output of a cup gun is low, the containers for the abrasive are in most cases smaller than 1 liter.

These devices are intended for hobby and leisure use. They do not place great demands on the compressor. It should be noted, however, that you also need a sandblasting cabin for sandblasting.

Sandblasting blower

They are available as mobile or fixed devices with different uses. They are either fixed or movable and intended for use in stationary blasting cabins.

Their performance is already aimed at professional users, the demands on the compressor are already very high (especially with regard to the amount of air and the pressure generated). Professional systems usually require high-performance compressors.

Free jet devices

Free jet devices are intended for mobile use in blasting cabins. The advantage of these devices is that they can be moved freely and can therefore also be used mobile within narrow limits.

Sandblasting accessories for the high pressure cleaner

The cleaning performance of high-pressure cleaners can be significantly increased if a blasting agent is added to the water jet.

So-called wet blasting is not a professional application technique, but is mainly used in the private sector. The accessories for branded high-pressure cleaners, including suitable blasting media, are easily available from specialist retailers.

Dry ice blasting

Here dry ice, i.e. frozen carbon dioxide at a temperature of -78 ° C, is used as the blasting agent. When it hits, the dry ice suddenly cools the top layer of the workpiece, making it brittle.

Soiling and surface coverings then immediately flake off with dry ice blasting, meaning that cleaning is effective, non-abrasive.

The dry ice can also be used in the form of dry snow. The method is only intended for professional use due to the high device costs.

However, since the blasting agent changes to a gaseous state and mixes with the ambient air, it can also be used mobile and outdoors without a blasting cabin. The process is not abrasive, i.e. the surface is not damaged, but only cleaned.

Micro sandblasting

Microsandblasting is carried out with special devices and is mainly used in electronics. Micro sandblasting can mill the finest channels in glass or silicon.

In addition to microfluidic channels and openings in components, the technology is also used for ultra-fine roughening of openings in electronic components.
