How to protect shot blasting robots from damage?

Dull, Dirty and Dangerous

When identifying what processes would benefit the most from implementing robotics, we usually focus on the “3D” processes – those that are Dull, Dirty and Dangerous. In addition, we also look at processes that require a high level of quality and repeatability. One of the processes that meets all of these criteria is shot blasting. However, the blasting process can be very harsh on the robots, causing frequent breakdowns. How can we protect the robots, to ensure they can safely work in shot blasting?

Protective cover

One of the ways to protect shot blasting robots, and arguably the most effective one, is using a protective cover. Of course, not any cover would do – in order to protect the robot from both blasting medium ricochet and dust generated in the process, while also allowing the machine to freely move in the programmed range, it needs to be made of fabric with very high abrasion resistance. It may come as a surprise, but fabric, if chosen properly, can last longer than metal in the blasting chamber!

Freedom of movement

Aside from fabric, another highly important factor in a shot blasting robot cover is the shape, or “construction” of the cover itself. As blasting robots can perform quite complicated movements to reach every part of the surface of the blasted object, it is highly important that the cover does not weigh them down or limit them in any way. Otherwise, it may turn out that the movement range of the robot is severely reduced.

Protect your blasting robot

To sum up: if you are thinking of implementing an industrial robot in a shot blasting process, definitely factor in a protective cover too! Do your research and find a solution that is custom and made of dedicated abrasion-resistant fabric, to ensure optimal safety of your robot. Ask for case studies and examples of similar covers made for that process. And for more information – contact EVOTEC!
