SHOT BLASTING WITH ROBOTS

We believe that our experience within the field of surface treatment mixed with a robots persistency and accuracy is what it takes to become a world leader of robotic solutions within anticorrosion. 

Quick facts about robotic shot blasting

  1. Our turntable solutions can handle parts up to 35 tons
  2. The robotic shot blasting process can handle nozzle sizes up to 22 mm and blast with up to 12 bars air pressure
  3. Our robotic solutions blast steel structures of significant sizes due to our unique servo driven 9-axis gantry system
  4. The robots are well protected with a neoprene suit and safeguarded with compressed air to avoid dust and grit particles
  5. A simulation of the blasting pattern can be performed to achieve an efficient blasting time
  6. The lifetime of the neoprene protection suit, when blasting with steel grit, is 6 months +
  7. The famous Clemco Denmark dual chamber blasting system can blast continously without stops
  8. The robotic program is open for programming in ABBs RobotStudio software

The picture above shows a gantry turn-key solution at a customer producing big steel components for the off shore industry. It is a complete shot blasting solution taylored for this specific customer and was installed in their excisting blasting booth.


Clemco Denmark assists, supports and takes action from the very beginning of a projeckt till the robot is up and running. For us it is very important that our customers get exactly what they ask for and that the solution works even better than they have hoped for. We experience that excisting customers having installed their first robotic solutions come back to us to expand their production with more robotic solutions for surface treatment.

Get into the details of our robotic solutions

A robotic solution for surface treatment from Clemco Denmark is based on a combination of 70 years of experience in surface preparation and the latests robotic motion programming. That is how we have managed to create some of the best robotic solutions for shotblasting, metallizing and spray painting of very large steel structures such as wind turbine towers. Get into the details of our technical information, our booths solutions and equipment.

Shot blasting and abrasive cleaning with robots

Denmark as a country has always been a forerunner of wind energy, and also of steel structures in the industry of wind energy such as wind turbine towers, nacelles and off shore jackets. These areas have been Clemco Denmark's working field for many years, and our main advantage is that we understand the abrasive cleaning process very thoroughly. We have achieved this knowledge from our many projects during the last 70 years. We know when a certain surface roughness and cleanness creates the correct surface preparation for a following zinc/aluminum metallization process. Each process - being shot blasting, metallization or spraypainting  - is carried out in a way to achieve the best conditions for the steel structure to go to next coating step.

 

For what concerns our robotic automation solutions we are feeding our robotic systems with the past 7 decades of knowledge. And that is what makes Clemco Denmark a world leader within robotic solutions for surface treatment in general. We believe that our experience within the field of surface treatment mixed with a robots persistency and accuracy is what it takes to become a world leader of robotic solutions within anticorrosion. For us, programming a robot, is the easy part. What requires knowledge is the shot blasting itself.

When coating clean steel structures with a zinc/aluminum coating you get a cathodic protection on the steel surface which prevents future corrosion. It sounds simple, but it requires an in-depth understanding of the shot blasting process itself, the steel abrasive recycling and cleaning as well as building rigid and long life systems. The manual process of blast cleaning with steel grit cannot just be transferred to a robotic solution. The robotic shot blasting requires a number of special alternations in order to work successfully and to be economically justifiable.

Special alternations required for robotic blast cleaning:

  1. The robot itself must be heavily protected against grit recoil and dust generated from the blast cleaning

  2. The robot blasting nozzle should move in a special pattern that rotates in circular and slightly overlapping tracks and sometimes perform quick swiping movements to release iron scale from the steel surface

  3. The robotic blasting booth must be protected by a special rubber or manganese steel cover to prevent excessive wear in hot spot areas

  4. The abrasive recovery and cleaning system should be able to handle abrasive material from two 19 mm blast nozzles blast cleaning without any breaks.

  5. The blast hose placement must be precisely aligned with the robot's movement
