HVLP spray gun with aluminum alloy body for automotive

This gun utilizes HVLP (High Volume Low Pressure) technology to improve paint transfer efficiency, reduce overspray and wastage, and reduce environmental pollution. It is suitable for professional technicians to carry out complete vehicle painting, partial repair and other high standard surface treatment work.

Features of HVLP Spray Gun

1. High efficiency and environmental protection, saving paint:
   Adopting HVLP environmental protection technology ensures the paint transfer rate is up to 65% or more, which reduces paint waste and is economical and practical.
   Low air pressure spraying reduces the spread of paint mist in the air, improves the working environment and reduces the impact of paint on human body and the environment.
2. Stable spraying performance, fine and smooth paint surface:
   Medium paint output, uniform paint film, suitable for most spraying technician’s operating habits.
   304 stainless steel nozzle and needle, corrosion and abrasion resistance, to ensure long time use without deformation, stable atomization effect.
   The gun body is made of high-strength aluminum alloy, formed by 280 tons of large-scale die-casting machine, and the internal channel is precisely processed to ensure stable and smooth spraying airflow and reduce paint film defects.
3. Precision manufacturing, durable:
   CNC machining: the gun body is shaped by a large CNC machining center, which ensures the high concentricity of the internal channel and improves the spraying uniformity and atomization effect.
   Strict quality inspection: Each spray gun passes two strict manual tests before leaving the factory to ensure stable atomization performance and meet the industry standard.
   High-precision adjustment knob: Precision CNC machining, smooth feel, flexible rotation, convenient for technicians to fine-tune the spray size and flow rate, to adapt to different spraying needs.

The Working Principle of HVLP Spray Gun

This spray gun adopts HVLP (High Volume Low Air Pressure) technology, which is different from the traditional high-pressure spray gun in that it uses a larger air flow rate and lower air pressure for spraying, thus improving the adhesion rate of the paint and reducing the waste of paint and environmental pollution.

Spraying Workflow

1. Air and paint mixing atomization:
   Compressed air enters the air channel inside the spray gun and forms a high-speed airflow through the precision-designed nozzle.
   The paint enters the nozzle through the material cup, and is uniformly atomized into tiny particles under the action of high-speed airflow.
2. Paint Transfer and Spray Control:
   Low air pressure reduces paint bounce and overspray, improves coating utilization, and ensures a more uniform sprayed surface.
   By adjusting the knob, the technician can accurately control the air flow, coating output and spray angle to suit different spraying needs.
3. Uniform coverage and improved coating quality:
   As the internal airflow channel of the spray gun has been processed with high precision, it ensures stable and even airflow, stronger paint adhesion and avoids color difference or uneven spraying during the spraying process.
   Low-pressure spraying can effectively reduce the “orange peel” phenomenon and improve the smoothness and gloss of the paint surface.

Application Areas of HVLP Spray Gun

1. Automobile industry: Suitable for automotive spraying, local repair and renovation of color change, to ensure that the paint film is uniform and smooth, improve wear resistance and weather resistance.
   Compatible with water-based paint, oil-based paint, metal paint, varnish and other automotive coatings to meet the needs of different processes.
2. Motorcycle spraying: Suitable for motorcycle fuel tank, frame, shell and other parts of the spraying, enhance the gloss and wear resistance of the paint.
3. Musical instrument industry: Used for spraying the surface of guitars, pianos, saxophones and other high-end musical instruments, providing a uniform and delicate coating and enhancing the texture of the product.
