Tell you 5 Reasons Why You Need a Spray Gun

Posted on by

Are you wondering how to solve the spraying problem more efficiently? Then you may need a good spray gun

Automatic Air Spray Gun can bring you 5 benefits

  1. Bring you the speed advantage
    For the same area, using a spray gun not only finish spraying quickly but also save time.
  2. Consistency of quality application
    The most feared thing in the spraying process is unevenness. Unevenness not only causes unsightly but also brings great troubles. A special spray gun can help you achieve the stability and consistency of the spraying quality.
  3. Control and reduce coating costs
    Spraying with a spray gun can reduce the cost of coating refills caused by uneven spraying
  4. Reduced labor costs
    An easy-to-use spray gun can help reduce labor costs, and you can achieve efficient work results without hiring so many workers.
  5. Easy to operate
    The spray gun only needs to determine the amount of spray material through the size of the hand pressure, and the detailed area can be controlled with a smaller force, so that less paint is sprayed, and the details of the sprayed surface can be modified more.

The spray gun can be applied in a wide range, including the following
applications:

  • Upholstery & Building materials spray
  • Automation equipment spray
  • Aerospace Technology spray
  • Furniture manufacturing spray
  • Car, yacht repair spray
  • Industry spray
  • Artistic creation spray
  • Electronic spray
  • Computer shell, mobile phone shell, cosmetic container shell spray
  • Model, ceramic glaze painting spray

Spray gun spraying methods are mainly divided into the following two types:

  1. Air atomized spraying
    Air spraying is the use of compressed air to flow through the nozzle hole of the spray gun to form a negative pressure. The negative pressure causes the paint to be sucked in from the straw and sprayed out through the nozzle to form a paint mist. The paint mist is sprayed on the surface of the painted parts to form a uniform paint film
  3. High-pressure airless spraying
    A kind of spraying method in which the paint is pressurized through the airtight container built in the high-pressure airless spraying equipment, and then the paint is atomized into fine particles through the nozzle and sprayed directly on the surface of the object

Choosing a Spray Gun – A Complete Guide

Posted on by

The intent of this article is to cover all the important things to consider and provide information to help you choose the right spray gun for you.

 

If you are just getting started in spray application you may be over whelmed by all the variables that are to be considered. From choosing the right coating, to safety considerations when spraying, to choosing the actual spray equipment. If you have been able to wade through the choices you may be at the point that you have decided you will be using a spray gun and want to determine which spray gun will best meet your needs.

 

Variable 1 – Fluid Viscosity

 

Viscosity is usually referenced as low, medium or high but if you do not have the viscosity of your coating provided you can also use a measuring device like a Zahn cup which will give you a reading in seconds. You can then use a conversion chart to determine the viscosity of a given coating. Most spray gun manufacturers including Binks and Devilbiss will often list the proper spray gun set up based on the coating viscosity you will spray using a certain cup like for the Trophy Gun the viscosity is listed in seconds in a Zahn 2 Cup. You can also often get a spray gun recommendation on the technical data sheet for your coating. However if you will be spraying a variety of coatings then having a general reference point of the coating type and viscosity of the coating will give you the ability to reference what spray gun setup might be ideal.  In general certain types of spray guns are better suited for heavy viscosity coatings than others.

 

For high viscosity coatings like zincs, enamels, ceramics, or glues you will typically want to use a conventional spray gun. Or if you need to spray even heavier bodied coatings or need higher production then you will often want to consider an Airless or Air Assist Airless.

 

For other coatings it will depend on your finish requirements. HVLP will help reduce the coating you use by having higher transfer efficiency. LVMP will allow for similar transfer efficiency to HVLP but may not meet environmental regulations in certain industries, conventional will provide the finest atomization but can use twice as much paint in a given time that HVLP will.

 

In addition to having implications for the type of gun to choose, viscosity will also be important in determining how fluid is delivered in a spray gun. The three ways to feed paint to a spray gun include pressure, suction, or gravity. Each feed method has its benefits and limitations. In general Gravity feed spray guns will keep waste to a minimum and provide ease of use. However to use a gravity feed spray gun the material must be thin enough to flow easily. Suction feed spray guns will have similar fluid flow requirements to gravity fed spray guns. Suction fed spray guns do offer potential agitators which can be helpful for coatings that require agitation. Suction feed spray guns will require slightly more cleaning. If your coating is highly viscous you will most often need a pressure fed spray gun. Pressure feed spray guns can supply highly viscous coatings easily making them the ideal choice for high viscosity coatings.

 

Variable 2 – Production Requirements

In addition to a variety of feed methods and air cap styles, high quality spray guns have a variety of set ups available. By offering larger air caps and fluid nozzles you will be able to choose a spray gun that will be able to provide the production level you need or if a spray gun is not fast enough you may want to consider an airless.  You can get an idea of what production you can expect out of various fluid nozzles here. The Air Cap you choose will determine a few important things including the size of the spray pattern and the caps ability to break up heavy viscosity coatings the higher the CFM of the air cap typically the heavier bodied coating it will atomize. BY knowing your production requirement you can be better able to choose the right fluid nozzle and air cap

 

In addition to choosing the air cap and fluid nozzle the Production requirement will be pertinent in choosing how you feed your spray gun. Pressure pots offer higher volumes of coating which can be ideal if you will be spraying more than a gallon of paint at a time. They also provide greater control over your fluid and air pressures which can help in meeting a production goal. Or if you need the ability to continuously paint you can feed your spray gun from a diaphragm pump or fluid transfer pump. If you will be painting in small quantities and not have coatings with high viscosity then gravity or siphon feed spray gun could be ideal.

 

Variable 3 – Compressed Air Availability

Different spray equipment will need different amounts of air. A typical spray gun can require 20 CFM of air while an airless can often require significantly more if it is air fed using up to 120 CFM. You can learn more about compressor requirements for spray equipment here.

 

Variable 4 – Finish Quality Requirements

A final variable to consider is the finish requirements you will need. Spray guns are typically the best appearing finishes. If the coatings are not highly viscous most of the times you can achieve an automotive quality break up of a coating with HVLP, Conventional, or LVMP.

 

However with heavier bodied coatings you will typically need a conventional gun to get good break up. An air assist airless will provide a finish that is close to a spray gun but not quite the fine finish, they are often used for higher production that requires a quality finish. If you primary need high production or spraying high solids coatings you will typically need an airless.

 

Variable 5 – Length and Diversity of Use

Spray guns vary greatly in their prices as well as their quality. Higher quality spray guns offer greater variety of air caps, fluid nozzles, and are able to be completely rebuilt. Lower cost spray guns will often not be rebuild able and have limitations on the variety of set ups that are available. You can learn more about spray gun prices and quality differences here.

 

Conclusion

Choosing the right spray gun for your coating can be a lot to consider. By knowing more about your finish quality, production, compressed air, and viscosity of your paint you will be able to better determine the right spray equipment for you.
