A robotic painting and coating solution can provide a wide range of advantages to manufacturers of all shapes and sizes. A well-engineered system is capable of increasing finishing quality, whilst delivering higher product speeds and productivity.
In parallel, the reduction in waste at the point source of origin drives down operating costs (in many cases significantly) and reduces volatile organic compound (VOC) emissions. Robotic painting systems have increased levels of uptime, and improved safety in hazardous working environments. Modern paint robot systems are easy to install and program, and the robots are deliver the same high-quality finish time after time without issues such as operators becoming tired or repetitive motion injuries. Where rotary atomisers are part of the end solution, robotic painting provides a significant paint saving when compared to a manual or fixed automation process, offering a quick return on investment (ROI).
Robotic solutions can be designed for solvent borne, waterborne, 2-component and 3-component applications, depending on the nature of the material being dispensed. Plastics are typically painted with a 2-component paint (a mix of resin and hardener) because of the low oven cure temperatures required. These 2-component paints often have an isocyanate component that may be carcinogenic when atomized, providing occupational health and safety concerns for manual operators. A robotic solution keeps operators away from the atomized isocyanates. In parallel, with the correct path development, the application can have a consistent film thickness, minimizing the excess paint required to meet specifications.
