How to Use Sand Blasting Equipment Top Sandblast Small Parts

Sandblasting proves an effective way of stripping of rust, dirt, paint, and other debris from surfaces. It is a way of attaining surface finish on different substrates like glass, metal, and wood. Sand blasting equipment uses compressed air to propel abrasives like glass beads or steel grit onto a target surface. This technique can almost restore a surface or substrate to its bare condition. Sandblasting may also be used to attain a desired texture on surface. While you may think that sandblasting is only used for cleaning walls or old paint, it can also be used for small objects. When used in small parts, it requires ideal protective measures and a great deal of preparation to attain the desired results and prevent injury or damage of a part. Here are tips on how to sandblast small objects.

Get the right media

You need to examine the small part you are sandblasting and use the right media. For general application, silica sand may be applied but because the substrates differ, you may want to change the abrasives accordingly. You can use glass beads or aluminum oxide for some hard surfaces. Be careful because using the wrong media may not bring the desired results or it could result in damage.

Place the part in ventilated area

You want to make sure that the area you are working is well ventilated. Ensure that you are away from surfaces or things that may be affected by sand bits flying astray. The exposed surfaces which are not being worked on can be covered with tarp or other material like plastic beads.

Use protective gears

You should wear protective equipment such as rubber gloves and goggles as well as respiratory masks before you operate the machinery. A painter suit consisting of a hood can be used to cover the entire body. It is likely that the abrasive material will ricochet directly towards where you are standing so ensure you are well protected. Without using protective equipment you are likely to sustain injury around the eye, skin, or other parts of the body. The high pressure abrasives can penetrate the skin or the eye.

Turn on the machine

By allowing the valves to turn off on the sandblasting machine, you can fill the unit with your preferred abrasive or media. Turn on the compressor and allow the air-line to open. The tank will release pressure which drives the abrasives onto the target surface. Make sure you stand about 8 to 16 inches from the part you are sandblasting, then start the sandblasting at a lower pressure setting while employing short bursts. Increase the pressure gradually ensuring that you get the desired results or effects on the surface or substrate.

If you are sandblasting small parts, you want to make sure you use the machine properly. It requires precisions and good practice to ensure safety and good results. Sand blasting equipment when used correctly can produce amazing results whether it is in rust removal, cleaning painted surfaces, or in removing dust and debris.
