Spray Guns


Contrast offers all types of paint spray equipment, including air spray, HVLP (High Volume Low Pressure), compliant/trans-tech, airless and air-assist, electrostatic, and powder guns and spray packages form the industry's leading vendors. 

 

Air Spray (Conventional) - Paint Spray Guns

Paint is applied to the part by pneumatic fluid atomization at higher air pressures. Air spray guns come in a variety configurations; siphon feed, gravity feed, and pressure feed. This type of spray gun is most commonly used for industrial finishing.

 

Advantages: Complete pattern control. Finest atomization. Good for high production rate applications.

 

Limitations: Uses more air. Creates the most fog. Low transfer efficiency.

HVLP - Paint Spray Guns

Similar to air spray gun in that it uses pneumatic fluid atomization except HVLP uses a higher volume of air at a lower pressure. The lower pneumatic pressure allows for less overspray. HVLP spray guns are commonly used in the automotive, general metal, aerospace, architectural coating, furniture finishing, and other fine finishing applications where material waste is of a great concern.

 

HVLP spray guns are often required by U.S. Environmental Agencies for high usage customers. HVLP spray guns come in a variety configurations; siphon feed, gravity feed, and pressure feed.

 

Advantages: High transfer efficiency (65% to 75%). Sprays well into recesses and cavities.

 

Limitations: Uses a high volume of air. Atomization not as fine as air spray guns.

Compliant (Trans-Tech) - Paint Spray Guns

Similar to HVLP spray guns in that it uses lower air pressure for pneumatic fluid atomization. Compliant spray guns are often required by European Environmental Agencies for high usage customers. Compliant spray guns combine the fine finish of air spray guns with the transfer efficiency of HVLP spray guns. Compliant spray guns come in a variety configurations; siphon feed, gravity feed, and pressure feed.

 

Advantages: High transfer efficiency like HVLP spray guns. Less air consumption than HVLP spray guns. Fine finish quality like Air spray guns.

 

Limitations: Use high volume of air. Not compatible with some U.S. Environmental Agencies for high usage customers.

Airless and Air-Assisted-Airless - Paint Spray Guns

Atomization caused by release of high pressure fluid that impinges through small orifice. Airless Atomization can be assisted by air atomization (air-assisted-airless) to provide a finer finish and break up the tailing effect at the edge of the spray pattern. Most widely used by painting contractors, structural metal finishers, and heavy equipment manufacturers.

 

Advantages: High fluid capability. Large patterns. Fastest spray application process. Low air consumption. Limited fog and “bounce back” – permits spraying into cavities.

 

Limitations: Potentially hazardous hydraulic injection. Higher rate of overspray due to high fluid output. Sharp patterns; difficult to blend. Expensive nozzles (tips). Coarse atomization may flood surface or create runs. Equipment requires top maintenance.

Electrostatic - Paint Spray Guns

Material is atomized using conventional air (pneumatic), airless (fluid impingement), air-assisted airless, or rotary atomizer principles. Particles are electrically charged and attracted to the part substrate. Electricity may be turned off to permit normal spraying.

 

Advantages: “Wrap" around effect is able to coat the back of the part while spraying from the front. Material savings through minimized overspray. Can be used with or without electrical charge.

 

Limitations: Some conductive materials will require special equipment or paint reformulation. Parts must be conductive and able to be grounded. Difficult to penetrate cavities or recesses with power supply on.

Powder Spray Guns

Powder Coating is a protective finish that is applied as an electrostaticly charged free-flowing powder. The main differences between a conventional liquid paint and powder coating is that the powder coating must be melted or cured after application, and powder coating does not require solvent to keep the protective coating in a liquid suspension during application.

 

Advantages: Powder coatings emit zero or near zero volatile organic compounds. Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating. Powder coating usually yields a part with a thicker protective coating layer and better performance.

 

Limitations: Initial capital equipment costs of powder coating equipment is far greator than a liquid spray system. Coating requires a cure oven to crosslink the powder particles. Proper part surface preparation is critical to coating adhesion and performance. It is difficult or impossible to cure parts that cannot handle the high temperatures generated during powder curing process.
