Automatic Powder Coating Lines

What is an automatic or automated powder coating system? There are some different ways to have a part powder coated. If the capacity is low, you can powder coat it manually with a gun, or booth, and then put the painted part into the oven. If the capacity gets bigger, you may require more extensive equipment and more capacity to have the same amount of parts to be painted in the same time period.

A bigger line may be a semi-automatic line where the movement of the parts is carried out by steel bars. These bars look like rails and the trolleys move within these rails inside and outside the booth and oven. This way the capacity can be a few times higher.

But in some cases, these semi-automatic lines can also not be sufficient and you need a more swift line to have a greater amount of parts to be coated in the same time period. This 3rd option is called the “Automatic powder coating system”.

Parts of an automatic powder coating lines

An automatic powder coating system can have the following parts:

• Surface pretreatment
• Drying
• Powder Coating
• Powder Curing
• Unloading and Loading new parts

Surface Pretreatment

Phosphating

Pretreatment- The preparation of a part prior to the application of a coating in order to improve adhesion & corrosion resistance.

Phosphating is a surface treatment process by which the virgin steel surface is converted to metallic phosphate & is widely used for preparing the metal surfaces before painting. (Thickness lies between 3 to 50 microns)

Phosphate coatings are produced by the chemical reaction of base metal with an aqueous solution of phosphoric acid and phosphates (Ions of Bivalent metals…Zn +2 , Mn +2 , Fe +2 ). Such coatings do not offer complete resistance to the atmosphere & principally used as an adherent base/primer coat for paints.

The Mechanism of the Phosphating

The free phosphoric acid in phosphating solution reacts with the Iron surface undergoing treatment in the following manner:

– Fe + 2H 3 PO 4 > Fe (H 2 PO 4 ) 2 + H 2

• The conventional seven-tank Hot Zinc Phosphating system is used.
• The following are the different steps involved in the process:
  • Alkali degreasing
  • Cold swilling
  • De – rusting
  • Cold swilling
  • Hot phosphating
  • Cold swilling
  • Sealing/Passivation

Drying Oven of Automatic Powder Coating Lines

The dipping type surface pretreatment process requires a fast drying operation after the chemical process to have good paint quality. Materials dry within 10-12 minutes by drying oven. Circulation canals and airflow is designed to have a fast, regular and economic drying operation.

The drying degree should not be over 125°C to save the phosphate covered on the material. The ideal temperature is between 100-110°C. The drying oven has been designed and produced by EMS Powder Coating Equipment. so as to increase the temperature to 120°C within 35-40 minutes.

Technical Specifications of a Drying Oven

• Heating type: With thermocouple, closed air circulation, indirect heating
• Heating Capacity: Calculated according to the capacity of the project
• Circulation fans : 3 Pieces x 4 kW Ø560
• Burner: Uret (Made in Turkey)
• Insulation: 150 mm.
• Air Curtains : 2 units x 3 kW = 6 kW
• Exhaust fan : 0,55 kW

Oven Body

The outside surface of the oven’s body is galvanized (powder painted); the inner side has been made of galvanized sheet metal, and have isolated with 150 mm Rockwool and 100 mm Glasswool, compressed into 150 mm of isolation. Panels of sandwich-shaped ovens are attached to each other with high heat resistant silicone

The Heating Unit of the Drying Oven

The heating unit’s capacity makes it able to increase the heat of the oven to 120 ºC. The firing room of the heat exchanger is made of AISI 310S quality stainless steel and its pipe sheaves are made of normalized caldron pipe. The body of the heating unit is isolated with150 mm Rockwool. Hot dry air prepared in the heating unit will be homogeneously distributed inside the oven with help of adjustable air canals which are made of galvanized sheet metal.

Stainless Steel Automatic Powder Coating Booth

The automatic powder coating booth is designed for automatic lines, where there is a conveyorized line carrying the parts into the booth. The booth has openings from each side for the reciprocators and can also have painter posts where the painter can stand with his manual powder coating gun and correct the unpainted parts (if there are any – this depends on the geometry difficulty) for better finishing.

Automatic powder coating booths are equipped with cyclons and an after filter group, dedicated to filtering the powder particles flying through the Cylon into the exhaust box.

Cyclon is cone-shaped equipment, where the air with flying powder particles is flying in from the upside part and circulates inside and this circulation of air helps the heavy particles (such as powder particles) to settle and sit down the cyclone and gets transferred to the powder coating booth back by a powder injector.

This powder coating injector works with the venturi principle and operates with compressed air.

Plastic (PVC) Quick color change powder coating booth

The plastic automatic powder coating booth operates with 2 robot reciprocators on both sides, whose working height can be determined according to the height of the workpieces.

Automatic Powder Coating Booths can be made from galvanized sheet, stainless steel and also PVC for fast cleaning options.

The air inside is calculated according to the space required inside of the booth and the circulating air inside the booth also determines the cyclone capacity

During the electrostatic powder painting process, approximately 70% of the paint sticks on the part, depending on the structure of the part. For the paint which does not get stuck on the part to not get spread in the environment, a “Powder Paint Application Booth” is required. Dimensions of the powder paint application cabinet, capacity, pressure of the sucking fan, filter count, using suitable filters, etc. is extremely important.

To create a suitable air velocity within the cabinet and overcome the resistance of the filters during the painting process, a fan with suitable quality must be selected; a sufficient number of filters must be used according to the number of powder paint guns to be used.

Because the remaining powder paint, which amounts to 30% of total paint and which does not stick to the part in the filtered type powder paint application cabinet is recycled directly, it keeps the physical specifications of the powder paint and removes the disabilities that are seen at second used powder paints such as becoming dull and denying the electrostatic.

Accumulated in the cabin floor paint is automatically directed to the cyclone swept pneumatic system. “Swept Paint Depot” and “Under Cyclone Depot” the accumulated powder coated are transferred back into the system with an automatic Powder Center. Thus, 3-4% in the filter group and very small paint particles move in, filter load decreases and life is prolonged. Filters are not changed during color changes, filter costs are reduced. Only the booth body color change in, cyclone group, and recovery system cleaning are enough. Paint Center is very efficient equipment for paint recovery.

In the powder paint cabinet, the filters must be kept clean and their pores must be open. Cleaning of the filters is automatically performed through an electronic card located on the command panel. The opening frequency and time of the pulse valves as well as the operating and stopping time of the sub-cyclone hopper can be set on the electronic card.

The pulse valves, which are set at the demanded frequency and which are opened respectively, pump compressed air into filters and pour out the powder, which was coated over the filters, to the residue hopper.

After the filters are cleaned, vibration motors operate automatically and transfer the paint accumulated in the hopper to the recycling hopper through sieving. This process goes on automatically as a set. The default settings of the electronic card were set considering its specifications and the number of powder paint pistols; however, the user is also able to make their own settings as per the terms of use change.

The Plastic Powder Paint Application Booth was designed and manufactured by EMS Powder Coating Equipment. to allow all types of powder paint to be applied. Dimensions of the cabinet, control panel, and equipment such as fan were designed according to the part to be painted, a number of Powder paint guns, and the facility where it will be used.

PVC powder coating booths are a great option for companies that need to change colors frequently. This type of booth is also great for companies that need to coat a lot of different types of products.

The most common type of PVC powder coating booth is the cyclone booth. This type is often used by companies that want to change colors quickly and don’t want to invest in many different booths.

Powder Coating Filters for the Automatic Powder Coating Booth

Powder coating filters are an essential component of automatic powder coating booths. They help to remove overspray powder coating from the air, preventing it from contaminating the environment and harming workers.

There are two main types of powder coating filters: cartridge filters and bag filters.

Cartridge filters are the most common type of powder coating filter. They are made up of a cylinder of pleated filter material that is encased in a metal housing. Cartridge filters are very effective at removing overspray powder coating from the air, but they can be expensive to replace.

Bag filters are less expensive than cartridge filters, but they are not as effective at removing overspray powder coating from the air. Bag filters are typically made up of a large cloth bag that is suspended from a metal frame. When the bag filter becomes clogged with powder coating, it can be emptied and reused.

How powder coating filters work

Powder coating filters work by trapping overspray powder coating particles in the filter material. When the air containing overspray powder coating is drawn through the filter, the powder coating particles are captured by the filter material and prevented from passing through.

Benefits of using powder coating filters in automatic powder coating booths

There are a number of benefits to using powder coating filters in automatic powder coating booths, including:

• Improved air quality: Powder coating filters help to improve the air quality in the powder coating booth by removing overspray powder coating from the air. This can help to protect workers from inhaling harmful powder coating particles.
• Reduced environmental impact: Powder coating filters help to reduce the environmental impact of powder coating operations by preventing overspray powder coating from being released into the environment.
• Improved efficiency: Powder coating filters can help to improve the efficiency of the powder coating process by reducing the amount of overspray powder coating that needs to be reclaimed.
• Extended oven life: Powder coating filters can help to extend the life of the powder coating oven by preventing overspray powder coating from clogging the oven’s filters.

How to choose the right powder coating filter for your automatic powder coating booth

When choosing a powder coating filter for your automatic powder coating booth, there are a few factors to consider:

• The type of powder coating being used: Different types of powder coating require different types of filters. For example, epoxy powder coatings require filters that are specifically designed to remove epoxy powder coating particles from the air.
• The production volume: If you have a high-volume powder coating operation, you will need a filter that can handle the high volume of overspray powder coating.
• The budget: Powder coating filters can range in price from a few hundred dollars to several thousand dollars. It is important to set a budget before making a purchase.

Conclusion

Powder coating filters are an essential component of automatic powder coating booths. They help to improve air quality, reduce environmental impact, improve efficiency, and extend oven life. When choosing a powder coating filter for your automatic powder coating booth, it is important to consider the type of powder coating being used, the production volume, and the budget.tunesharemore_vert

During the painting process, the paint which did not stick on the part, with the effect of the suction valve, by sticking on the filters their extrusion to the external environment is avoided.

The paint is poured onto a powder hopper with a sieve as the filters are cleaned through a reverse washing line (pulse valves). To clean the filters, compressed air is transmitted into the filters automatically. This process is fulfilled by means of the pulse valves commanded by the electronic card.

Design and Function of Powder Filter Units

Powder filter units are produced for mass production areas. EMS powder filter units are designed to be cleaned easily and to be managed by a PLC system. A few significant features are listed below;
-High-efficiency filtration.
-Proper for continuously working lines.
-Strength filter.

Function definition

While the filter unit is in operation, the contaminated air enters through the inlet of the filter unit and passes through the filter cartridges. The powder/dye mixture is collected on the outside of the filters. The filtered air passes through the filters and it is returned from the output filter as clean air to the ambient.

The filter cartridges are automatically cleaned at regular intervals. Thus, the filter units can be used efficiently. During the cleaning of the filter unit, the timer sends energy to the solenoid valve and it is given compressed air from the diaphragm valve to the filters at the same time. ( to outward from the inside of the filters.)

Therefore, The powder/dye mixture which is collected outside of the filter pours under the filter unit and it is cumulated in the waste storage. With the aid of the fan on the filter unit, firstly, the dust passes through from air canals in the plastic powder coating booth. It is held in filters after passes from the cyclone separator. It is ensured the air that is given outside can keep clean. Besides, air/powder mixture concentration can keep away from explosion potential interval because of the suction fan speed

Plastic Spray booth manufacturers try to solve the cleaning problem after each color change by either inventing a new powder coating booth design or applying new antistatic materials for the booth construction. As the powder coating cost increases in accordance with the energy prices, companies need smaller stops between each color change.

The Setup and Startup of the Filter Unit

It is needed to apply the following substances if the first time operation or long periods of stoppage.

• Make sure that there is no dust/impurity on the fan outlet.
• Make sure that the waste storage is placed under the filter unit.
• Set the air damper to a 75% open position.
• 4)Make sure that the inspection hatch is closed.
• Turn on the energy from the switch.
• Measure the air flow with a micromanometer and set the airflow through the damper. If the air stream is higher than the level wanted, the fan and the filter lifetime reduce seriously.( It should be done by an authorized service.)
• Give the compressor air and set it to 6 bar. Above 7 bar of air can damage the filter.

Application of the Filter Unit

Before every operation, apply the above following.

• Read all user manuals, which are sent with the filter unit instructions.
• Check the grounding of the filter unit
• Listen to the fan noise. If exists noise is more than the normal level, the fan can be problematic.
• If it is proper, test the filter unit functions
  During long stances
• Clean the clean air room.
• Check the pulse valve timer. ( It should be done by an authorized service.)
• Check the waste storage of the filter unit to be sure in its place. If it is needed, it can be emptied.
• Check the compressor air and air/ water concentration.
• Check the pulse valve for air leaks.
• Check the door of the filter against leakage.
• Check the elbow for air leaks.
• The filters should be changed after using 2 years. ( for the one shift)
  In operation,
  -Operate the compressor and set up inlet pressure. ( generally 6 bar)
  -Turn on the main switch.
  -Check the operation of the system and control data of guns from the main control cabinet.
  While stopping operation,
  -If the booth is managed automatically, stop automatic mode.
  -Turn off control units.
