High Voltage Airless Spraying Technology
High Voltage Airless Spraying Technology (HVAST) is a form of advanced technology in the field of metal spraying. In HVAST, a high voltage, direct current arc is used to atomize the working material into small particles and uniformly spray them onto the surface of a part or substrate. Designed to offer improved efficiency and cost savings compared to traditional techniques, HVAST has been widely adopted by many major companies in the metal spraying industry.
The uniqueness of HVAST technology lies in its use of the more effective and efficient direct current arc for atomization. By doing so, HVAST can atomize the working material more evenly and precisely than traditional techniques. Additionally, by using a direct current arc, the atomized particles are held together more strongly and prevented from bouncing or dissipation. This results in much smaller and more even particles being sprayed onto the surface, resulting in smoother finishes and better adhesion performance.
The main advantage of HVAST is its ability to reduce the amount of materials needed for metal spraying jobs. This reduces raw material costs and energy expenditure, both of which can lead to lower overall costs. HVAST is also much faster than traditional metal spraying techniques, which makes it appealing to those looking to reduce their time investment.
HVAST is also safer than traditional methods, as the high voltage arc used in HVAST is self-sustaining and not as easily ignited than oxy-fuel torches. Additionally, the process of HVAST requires no combustible gas, meaning there is little risk of fire and explosion.
Due to these advantages, HVAST has become one of the most popular metal spraying methods for a wide range of industries. From aeronautics to automotive manufacturing, HVAST is being used to provide more efficient and cost-effective metal spraying solutions. In addition, many major companies in the metal spraying field have adopted HVAST for its performance and cost savings.
HVAST technology is expected to remain one of the most popular metal spraying technologies in the near future. By providing improved efficiency, cost savings, and safety, HVAST is set to remain an integral part of the metal spraying industry and a highly sought-after technology.
