Airless spray application shall be in accordance with the following procedure:
as per steel structure paint Manual Vol.1 & Vol.2 by SSPC, USA, Air less spray relies on hydraulic pressure rather than air atomization to produce the desired spray. An air compressor or electric motor is used to operate a pump to produce pressures of 1000 to 6000 psi.
Paint is delivered to the spray gun at this pressure through a single hose within the gun. A single paint stream is divided into separate streams, which are forced through a small orifice resulting in atomization of paint without the use of air. This results in more rapid coverage with less over spray.
Airless spray usually is faster, cleaner, more economical and easier to use than conventional air spray.

The unit shall have inbuilt agitator that keep the paint uniformly mixed during the spraying. The unit shall consist of inbuilt strainer. Usually very small quantities of thinning are required before spray. In case of High Build Epoxy coating (two pack). 30:1 pump ratio and 0.020-0.023” tip size will provide a good spray pattern. Ideally fluid hoses should not be less than 3/8” ID and not longer than 50 ft to obtain optimum results. In case of gun choking, de-choking steps shall be followed immediately.
[b]What Are Spray Painting and Powder Coating?[/b]
Spray [url=https://www.westwu-machine.com/pipe-spray-painting-machine/steel-pipe-painting-production-line/]Steel Pipe Painting Production Line[/url] is the process of applying liquid paint using pressure. This can be done in one of three ways:
Conventional high-pressure spraying
High-volume low-pressure (HVLP) spraying
Conventional High-Pressure Spray Painting
This method uses an air compressor and an air gun. When the gun's trigger is pressed, the paint mixes with the compressed air stream and a fine spray is released from the nozzle.
The air gun is usually held about 6 to 10 inches from the object being painted and moved back and forth over the surface to ensure an even and continuous coat.
Airless Spraying Systems
These [url=https://www.westwu-machine.com/pipe-spray-painting-machine/steel-pipe-spraying-coating-machine/]Steel Pipe Spraying Coating Machine[/url] systems use a high-pressure pump, which can range in pressure from just 300 to 7,500 pounds per square inch, depending on the application.
Laser marking works by using a focused beam of light to mark the surface of a material. When the beam interacts with the material’s surface, it alters the material’s properties and appearance. This concentrated beam targets only a specified area, allowing the laser [url=https://www.westwu-machine.com/automatic-marking-machine/]Automatic Marking Machine[/url] to create precise, high quality, high-contrast marks that are easy to read or scan on virtually any surface. This feature makes laser marking ideal for applications where accuracy and permanency are critical to success.
There are several types of laser marking systems, and each operates slightly differently. The correct process to use the machine also depends on the material you’re working with and the application you’re using. MECCO offers a list of resources to help you operate your machine and troubleshoot any issues, from how-to videos to detailed documentation. When using any laser marking machine, it’s important to follow all safety guidelines. Thanks to a variety of preventative measures, including safety enclosure options, laser marking is a relatively safe process.
