Sandblasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface containments.
Spray painting including electrostatic spray painting is a process by which liquid paint is applied under pressure to an object. Different spraying processes can be used to atomize the paint
Using a conventional air compressor
Air is driven across the mouth of a small outlet under pressure to draw liquid paint out of the container and produce an air-paint mist from the nozzle of the spray gun
Airless spray painting
The paint container is pressurized pushing the paint to the nozzle where it is atomized by the spray gun.
An electrostatic spray painting
An electric pump drives the electrostatically charged liquid paint out of the nozzle which is then applied to the object which is earthed.
A process by which electrostatically charged powder is applied onto an earthed object. Spray painting and powder coating are carried out in a variety of industries. For example, items that are commonly spraypainted include motor vehicles, buildings, furniture, white goods, boats, ships, aircraft and machinery.
Challenges within the application
Technique/skills are required to achieve wanted results, especially for complex objects.
Traditional robot movements are too stiff
in currently automated solutions. This results in large amounts of paint waste if path / speed / acceleration controls are not provided.
Safety equipment and precautions costs for human workers. Manual workers get exposed to hazardous chemicals, work in fire and explosion-risky, confined, noisy and highly humid environments. repetitive processes affect their overall body posture.
