COATING ATOMISERS
Paint atomisation is a crucial process in the application of liquid paint, where the paint is broken down into fine droplets to ensure uniform coverage and adhesion. Aerostatic air bearing spindles are used to achieve this by utilising rotating bell cups, where the paint leaves the periphery at high speed and is attracted electrostatically to the target surface. This process is essential for achieving a smooth, even finish and is influenced by various factors such as paint type, viscosity, and flow rate. Proper atomisation not only enhances the aesthetic quality of the coating but also improves its durability and the efficiency of application.
A typical atomiser spindle is turbine driven to speeds of up to ~100krpm, so the coating (normally paint) can be electrostatically deposited onto a surface. Robotic systems are common in the automotive world, facilitated by the low spindle mass and compact form factor. ABD has a range of different products to suit different applications.
ABD has many years of experience in designing and manufacturing air bearing turbine spindles capitalising on the advantages, particularly in terms of efficiency and coverage. Here are some key benefits of using ABD atomisers :-
High Efficiency: The turbine spindle technology allows for the atomisation of paint with minimal energy loss, making it a more efficient option compared to traditional methods.
Increased Coverage: An electrostatic charge provides more even coating on features and non-uniform surfaces, ensuring a more extensive application of paint.
Improved Quality: The atomisation process results in smaller and more homogeneous paint droplets, leading to better film uniformity and adhesion.
Versatility: The turbine spindles are versatile as can be mounted on gantries or robotic arms, and can be used for various applications, including automotive, aerospace, and consumer goods.
Environmental Benefits: The use of turbine technology can lead to reduced paint waste with lower VOC emissions and for water-based systems, contributing to a more environmentally friendly manufacturing process.
These advantages make the turbine paint atomizing process a preferred choice for many industries, especially those that require high-quality, efficient, and environmentally friendly paint applications.
