Safety Parameters of the Best Powder Coating Gun for Beginners
Safety Parameters of the Best Powder Coating Gun for Beginners
The powder spray gun is only suited to the application of powder paint. EMS Powder Coating Equipment forbids any other use!
The powder spray gun may only be operated under the following conditions if: the operating staff has previously been trained on the basis of this operating manual, the safety regulations listed in this operating manual are observed, the operating, maintenance, and repair information in this operating manual is observed, and the statutory requirements and accident prevention regulations standard in the country of use are observed. The spray gun may only be used if all parameters are set and all measurements / safety checks are carried out correctly.
Reasonably Foreseeable Misuse
The following is prohibited:
Coating workpieces that are not grounded
Unauthorized conversions and modifications to the spray gun
Processing liquid or similar coating materials
Using defective components, spare parts, or accessories other than those described in chapter 12 of this operating manual
The forms of misuse listed below may result in health issues and/or damage to property:
Use of damp powder paint
Incorrectly set values for powder discharge
Incorrectly set electrostatic values
Cleaning and Maintentance
Before starting a cleaning or any other manual work, the high-voltage in the spray area must be shut down and locked to prevent it from being switched back on. Lock the supply of compressed air and decompress the system. Secure the device against being switched back on without authorization.
Use only electrically conducting and grounded containers for cleaning fluids. Preference should be given to non-flammable cleaning fluids. Flammable cleaning fluids may only be used if, once the high-voltage has been switched off and all parts carrying high-voltage are discharged to a discharge energy of less than 0.24 mJ before they can be reached.
Most flammable solvents have a fi ring power of around 24 mJ or 60 nC. The cleaning agent’s flash point must be at least 15 K above the ambient temperature. Only mobile industrial vacuum cleaners of design 1 (see EN 60335-2) may be used to remove dust deposits.
With the high-voltage switch on, a luminous or corona discharge occurs at the electrode tip; this can only be seen in the dark. This physical effect can be seen when the electrode is brought near the grounded workpiece. This luminous discharge does not involve any fi ring power and has no effect on system handling.
When the electrode approaches the workpiece, the control unit automatically reduces the high voltage to a safe value. If you touch plastic parts of the spray gun with your finger, harmless discharges may occur due to the high-voltage field around the spray gun (so-called brush discharges). However, these do not contain any firing power.

For small production volumes or for special colors a small booth for manual coating is often sufficient, which from the price, and space requirements can be fitted into any production workshop.
Powder Coating Setup
A powder coating setup consists of a series of components and processes that work together to apply powder coating to a workpiece. The specific components and processes may vary depending on the size and complexity of the workpieces, the desired finish, and the production volume.
Key Components of a Powder Coating Setup
Pre-Treatment System: The pre-treatment system prepares the workpiece surface for powder adhesion by removing contaminants like grease, oil, and rust. It may involve degreasing, etching, and phosphating.
Powder Booth: The powder booth provides a controlled environment for applying the powder coating, preventing overspray and contamination of the surrounding environment. It typically includes walls, a ceiling, a floor grate, an exhaust system, and powder coating guns.
Powder Coating Gun: The powder coating gun atomizes the powder particles into a fine mist using electrostatic or mechanical principles. Electrostatic guns charge the powder particles, while mechanical guns rely on air pressure.
Workpiece Handling System: This system transports the workpieces through the various stages of the powder coating process, maintaining proper positioning and orientation. It may involve conveyor belts, rotating turntables, or manual handling.
Curing Oven: The curing oven cures the applied powder coating, transforming it into a durable and hard finish. It heats the powder particles to a specific temperature for a specified time, allowing them to melt, flow, and crosslink.
Powder Recovery System (Optional): A powder recovery system collects overspray powder, minimizing waste and allowing for powder reuse, further promoting sustainability.
Process Steps of a Powder Coating Setup
Surface Preparation: The workpiece is thoroughly cleaned and prepared to ensure optimal powder adhesion.
Powder Application: The powder coating gun applies a fine mist of powder particles onto the pre-treated workpiece. Electrostatic guns attract the charged powder particles to the grounded workpiece, while mechanical guns rely on air pressure to propel the powder particles.
Curing: The coated workpiece is placed in a curing oven, where the powder particles are heated to a specific temperature for a specified time. This curing process allows the powder particles to melt, flow, and crosslink, forming a durable and hard finish.
Cooling: After curing, the workpiece is allowed to cool down to room temperature.
Quality Control: The coated workpiece is inspected to ensure a uniform and defect-free finish.
Additional Considerations for Powder Coating Setup
Ventilation and Exhaust System: A proper ventilation and exhaust system is crucial to remove harmful fumes and VOCs from the powder coating process, ensuring a safe working environment.

Environmental Considerations: Incorporating energy-efficient equipment, powder recovery systems, and wastewater treatment solutions can minimize environmental impact.
Future Expansion: Consider future production growth and potential process enhancements when designing the powder coating setup.
Surface Pretreatment before Powder Coating Setup
Surface Pretreatment before Powder Coating Setup
Before the workpieces can be coated, they must be freed of all contamination such as grease, oil, etc. This takes place in the multizone pre-treatment plant. After cleaning follows mostly, according to material, the pickling, phosphating, or chromatizing. Generally, a distinction is made between steel sheet, which is phosphate for corrosion protection, galvanized steel sheet which is pickled to improve adhesion, and aluminum sheet which is achromatized.
Workpieces, such as steel containers, wire goods, turned, punched or pressed parts, bicycle parts, and accessories pass through the different treatment zones on the chain conveyor. The pre-treatment must be accommodated to suit the workpieces. Dimensioning means wasting energy and raw materials. The final coating results depend significantly on the cleaning and pre-treatment. Measures for effective environmental protection and recycling of raw materials are to be principally integrated into the pre-treatment concept.

The Water Dryer or Drying Oven
When the workpieces have passed through all the pre-treatment stations on the chain conveyor, any residual moisture must be removed. This takes place in the residual water drier. This is similar to the powder dryer, but are designed only for temperatures up to 120° C (248° F). Depending on the type of workpiece, blowing with normal air with nozzles may be sufficient, but it always depends on individual cases, what outlay is required.
A prerequisite for the successful use of powder enamel is absolutely perfectly pre-treated steel. In order to achieve the necessary level of quality, pre-treatment lines with up to 20 stages are possible. As a rule, working is reduced to 6 stages (3x degreasing, 2x rinsing, 1x soak cleaning), whereby, this saving is only possible through the choice of suitable coating materials, as only high-quality steel can be pre-treated with only 6 stages.
The Powder Coating Booth and Spray Guns
The Powder Coating Booth and Spray Guns
In principle three different charging processes are used for powder coating: electrostatic charging, low-grade ion charging, and Tribo charging. The air ion reduction is achieved by practically all powder gun manufacturers through a special accessory (corona ring) on the powder gun. A fourth possibility is fluidized bed coating, which, at any rate, operates without electrostatic and is to be classified as an exception.
The Electrostatic Charging
The Electrostatic Charging
The corona discharge is the unimpeded discharge of free electrons from an electrical conductor. This process is only possible under a high electrical field strength. This increases with increased voltage and with decreased wire thickness, which is why a high voltage and a thin wire are required. The free electrons seek the shortest route to the next grounded part.
They contact the powder particles and remain adhered to them. Thus ionized powder particles are attracted to all grounded objects like the free electrons. In practical use is the workpiece the first grounded part that the powder meets and therefore, remains adhered to it. As soon as the ionized powder particles meet the grounded workpiece, a “counter-charge” is created on the workpiece.
Both charges mutually attract one another. Because the powder is not electrically conductive, the charge cannot discharge and the attractive force remains. The discharging current consisting of free electrons, air ions, and the influence current of the counter-charge, flows from the grounded workpiece. To guarantee optimum charging of the powder, the electrons of the EMS powder guns are rinsed with a small stream of air.
Without this rinsing, the powder will sinter on the electrode in the shortest time and its electron flow will be considerably reduced. The air stream increases the corona discharge on the electrode because the electrons are flushed away. About 1 – 3% of the free electrons hit powder particles, the rest ionize in the surrounding air or remain free. These free electrons and the ionized air are called space charges and have an influence on the quality of the coating.
As already mentioned, the charged powder particles seek the shortest route to the next grounded object. The space charge amplifies this force and the powder particles have a problem penetrating into cavities and depositing on the edges and in the corners of the workpieces. We know that the charged powder particles repel all similarly ionized powder particles. This repelling force is also active with powder particles deposited on the workpiece. It limits the coating thickness and increases the even distribution of the powder.
When the powder film on the object is too thick, an uneven surface, called the ‘orange peel’ effect, is created. Another manifestation is, that powder is sprayed back, called back-ionization, whereby small craters are formed on the surface. When the high-voltage is reduced on the electrode, the charging, and space charge are also reduced, so the ‘orange peel’ effect and back-ionization can be combated. Due to this procedure, the charging of the powder is also reduced, and its ability to penetrate into cavities also sinks.
Low-grade ion charging, with the retrofitting of a corona ring, comes into use everywhere where thicker powder film and high visual coating quality are required simultaneously. It is not always possible to achieve high surface quality with the usual electrostatic charging, where cavities are to be covered and the leading edges must be smooth simultaneously. Either the cavities cannot be covered, or the edges are too thickly coated, which coating thicknesses of 60 – 70 µ the notorious ‘orange peel’ form.
This results from an excess of free ions, which cannot discharge through the object due to the too-thick powder film and this leads to an uneven coating. The corona ring prevents the free ions from reaching the workpiece, in that they are fed back, through the ring for grounding the powder gun.
The ring consists essentially of a conductive ring with six electrodes and a connecting wire fixed to the grounded powder gun fixture. Typical fields of application for the corona ring is the coating of drawers, wheel rims, and sections. Another field of application is also coating with structured powders, where the corona ring leads to a considerably well-balanced pattern. In addition, it reduces back-ionization when coating manually
Manual coating: High-performance equipment for manual coating is ideally suited for small to medium production series. They should always be easy to clean because color changes may be frequent.
Automatic coating: High-performance equipment for automatic coating must the ability to fulfill the requirements for the production of large series. Individual modular systems, with standard elements, which permit a tailormade solution for every paint shop, are predestined for such tasks.
Even when the powder particles are properly charged, many miss their target, the workpiece. Electrostatic powder coating is so economical because the overspray can be recovered, and reused. Individual booths operate with different recovery systems. Further information on this is found in the following text. What all have in common is, that the workpieces are coated in a booth, in a permanent, slightly lower pressure created by the exhaust suction. Overspray is prevented from escaping from the booth by the intake air flow created.
The Powder Coating Reciprocator Robots
The Powder Coating Reciprocator Robots
In order to achieve an adequate rationalization of the production process with the coating of medium and large series the procurement of reciprocators is indispensable. An exactly reproducible coating performance of standard uniformity and coating thickness is first possible through the customer-specific layout of the reciprocator stations.
These automatic machines can be operated in up to three dimensions as required, whereby, in addition to the advantages already mentioned, the manual touch-up coating will often be unnecessary. At any rate, larger series must be produced with multi-dimensional automation, otherwise, the considerable programming effort will neutralize the coating advantages again.
Today, in large paint shops several two-dimensional reciprocators, with about four powder guns each, are no longer uncommon, particularly because these are controlled from a single, compact control unit, which guarantees a uniform coating quality.
Powder Curing Oven
Powder Coating Curing Oven
After the application of the powder, the workpieces can be transported directly into the curing oven without delay. The final finish depends on the accuracy of the temperature. The stoving temperature tolerance of the powder is about ± 5° C (± 9° F). Heating-up and holding times are influenced of the volume of the oven’s interior components such as partition walls, reinforcements, or heat insulation. But also the workpiece type, concentration of hangers, and material thickness are important criteria for the design of the oven.
Generally, there are various designs of ovens on the market. Whether a continuous oven, a reversing oven, or any one of the various other designs is to be recommended, will depend on the overall plant concept, and space requirements. A further important factor is the dwell time duration in the oven. With a continuous oven, it is clear that for a planned workpiece flow rate the specified temperature, with an acceptable tolerance, must be guaranteed. Hardening is done at differing temperatures according to the type of powder.
Heat energy is expensive, which is why economic measures in this area will always remain a topical theme. The designer with a sense of responsibility will integrate this problem in his concept and know, with which measures the energy consumption is kept as low as possible. A few of the criteria listed below will help in making a decision:
Direct or indirect heating? With direct heating about a 10 % energy saving can be made, however, only gas can be used as the heating medium.
Opening losses are avoided with an A-Zone design.
The heat insulation must be correctly designed, radiation losses must be avoided.
Heat recovery systems lower energy requirements.
Electrostatic powder coating is becoming increasingly important. The growth rate of this environmentally friendly technology is far above average. Floor space and personnel costs can be kept low through compact plant design, and the possibility to automate extensively. Since coating takes place in a closed system, without solvents, there are no harmful side effects.
The efficiency of this technology, depending on the recovery system, is up to 99%. This makes powder coating one of the most economical of all surface finishing technologies. With the relatively new development of so-called quick color change systems, a color change can be carried out within fifteen minutes. Powder coating is becoming more and more a replacement process for wet coating, which is considerably less environmentally friendly.

If you are unsure about which voltage powder coating gun to choose, it is always best to consult with a professional. They can help you to assess your needs and choose the right gun for the job.
Spray patterns of the Professional Powder Coating Gun
The spray patterns of a powder coating gun determine how the powder is applied to the substrate. There are three main types of spray patterns:
Flat spray: This spray pattern produces a wide, flat fan of powder. It is ideal for coating flat surfaces, such as metal panels and appliance enclosures.
Round spray: This spray pattern produces a round cone of powder. It is ideal for coating cylindrical objects, such as pipes and tubes.
Vertical spray: This spray pattern produces a vertical strip of powder. It is ideal for coating tall, narrow surfaces, such as window frames and furniture legs.
Some powder coating guns also have additional spray patterns, such as triangular and elliptical. These patterns can be used for specialized applications, such as coating corners and recesses.
When choosing a powder coating gun, it is important to consider the spray patterns that you will need for the applications that you will be using it for. If you will be coating a variety of surfaces, it is best to choose a gun with multiple spray patterns.
Here are some examples of how different spray patterns can be used:
Flat spray: To coat a metal panel, you would use a flat spray pattern. This would produce a uniform coating across the entire surface of the panel.
Round spray: To coat a pipe, you would use a round spray pattern. This would ensure that the powder is evenly distributed around the circumference of the pipe.
Vertical spray: To coat a window frame, you would use a vertical spray pattern. This would allow you to apply a consistent coating to the entire length of the frame without having to move the gun back and forth.
By choosing the right spray pattern for the job, you can ensure that your powder coating projects are completed quickly and efficiently.
Flow Rate
The flow rate of a powder coating gun determines how much powder is applied to the substrate per unit time. The flow rate is typically adjustable, which allows the user to control the thickness of the coating.
A higher flow rate will produce a thicker coating, while a lower flow rate will produce a thinner coating. The ideal flow rate will vary depending on the type of powder being used, the substrate being coated, and the desired thickness of the coating.
Here are some factors to consider when choosing a flow rate:
Type of powder: Different types of powder coatings have different flow rates. For example, epoxy powders typically have a higher flow rate than polyester powders.
Substrate being coated: The substrate being coated can also affect the flow rate. For example, a porous substrate will require a lower flow rate than a non-porous substrate.
Desired thickness of coating: The desired thickness of the coating will also affect the flow rate. For example, a thicker coating will require a higher flow rate.
It is important to note that too high of a flow rate can result in a dripping or sagging coating, while too low of a flow rate can result in a thin and inconsistent coating. It is always best to start with a low flow rate and increase it gradually until the desired thickness of coating is achieved.
Here are some tips for adjusting the flow rate of a powder coating gun:
Consult the manufacturer’s instructions for your specific gun.
Start with a low flow rate and increase it gradually until the desired thickness of coating is achieved.
Test the flow rate on a scrap piece of material before coating the actual workpiece.
Make adjustments to the flow rate as needed during the coating process.
By carefully adjusting the flow rate of your powder coating gun, you can ensure that your projects are completed with a high-quality finish.
Flat Spray
The flat spray nozzle of the powder coating gun is the part that is responsible for creating the flat spray pattern. It is typically made of metal or plastic and has a series of small holes that the powder passes through. The size and arrangement of the holes determines the width and thickness of the spray pattern.
Flat spray nozzles are available in a variety of sizes and configurations to suit different powder coating needs. Some nozzles are designed for general-purpose use, while others are designed for specific applications, such as coating large surfaces or surfaces with complex geometries.
When choosing a flat spray nozzle, it is important to consider the following factors:
The size and type of powder being used: The size and type of powder will affect the flow rate and spray pattern. For example, finer powders will require a smaller nozzle orifice.
The substrate being coated: The substrate being coated can also affect the flow rate and spray pattern. For example, porous substrates will require a lower flow rate than non-porous substrates.
The desired thickness of coating: The desired thickness of the coating will also affect the flow rate and spray pattern. For example, a thicker coating will require a higher flow rate.
It is important to note that the flat spray nozzle is just one part of the powder coating gun. The other components, such as the gun body, powder feed system, and air compressor, also play a role in creating the final spray pattern.
Here are some tips for using a flat spray nozzle:
Clean the nozzle regularly to prevent clogging.
Use the appropriate nozzle size for the powder and substrate being used.
Adjust the flow rate and spray pattern to achieve the desired results.
Test the spray pattern on a scrap piece of material before coating the actual workpiece.
By following these tips, you can ensure that your flat spray nozzle performs properly and helps you to achieve a high-quality finish on your powder coating projects.
Round Spray
Round spray is a type of spray pattern that produces a round cone of powder. It is ideal for coating cylindrical objects, such as pipes and tubes. Round spray can also be used for coating flat surfaces, but it is not as efficient as flat spray for this application.
To achieve a good round spray, the gun should be held at a distance of 4-6 inches from the substrate and the powder should be applied in a sweeping motion. The gun should be kept perpendicular to the substrate and the powder should be applied evenly across the entire surface.
Here are some tips for achieving a good round spray:
Hold the gun at a distance of 4-6 inches from the substrate.
Apply the powder in a sweeping motion.
Keep the gun perpendicular to the substrate.
Apply the powder evenly across the entire surface.
By following these tips, you can achieve a uniform and consistent coating with a round spray pattern.
Here are some examples of round spray powder coating:
As you can see, round spray can be used to create a variety of effects, from a smooth, uniform finish to a more textured, patterned finish. It is a versatile spray pattern that can be used for a variety of powder coating applications.
