Oil Filter Powder Coating

Oil filter powder coating is a process of applying a dry powder coating to an oil filter. This is done to protect the filter from corrosion and other damage. The powder coating is typically applied using a spray gun, and then cured in an oven.

Here are the steps involved in oil filter powder coating:

1. Preparation: The oil filter is first cleaned and prepared for coating. This typically involves removing any dirt, grease, or other contaminants.
2. Masking: Any areas of the filter that do not need to be coated are masked off. This is done to prevent overspray from getting on these areas.
3. Powder Application: The powder coating is applied to the filter using a spray gun. The powder is typically applied in a thin layer, and then allowed to dry.
4. Curing: The filter is then placed in an oven to cure the powder coating. This typically involves heating the filter to a temperature of around 300 degrees Fahrenheit for 20-30 minutes.
5. Inspection: The filter is then inspected to ensure that the coating is even and free of defects.

The benefits of oil filter powder coating include:

• Protection from corrosion: Powder coating is a durable finish that can protect the filter from corrosion.
• Improved appearance: Powder coating can give the filter a more finished appearance.
• Resistance to damage: Powder coating is a hard finish that can resist damage from abrasion and other sources.
• Extended filter life: Powder coating can help to extend the life of the filter by protecting it from damage.

Oil filter powder coating is a relatively new process, but it is quickly gaining popularity due to its many benefits. If you are looking for a way to protect your oil filters from corrosion and other damage, then oil filter powder coating is a great option.

Oil Filter Powder Coating

Oil filter powder coating is a process of applying a dry powder coating to an oil filter. This is done to protect the filter from corrosion and other damage.

Benefits of Oil Filter Powder Coating

1. Corrosion Protection: Powder coating provides a durable finish that can protect the oil filter from corrosion caused by moisture, salts, and other chemicals.
2. Abrasion Resistance: Powder coating can withstand abrasion and wear, which is important for oil filters that are exposed to harsh environments.
3. Chemical Resistance: Powder coating can resist chemicals that are commonly found in engine oil, such as detergents and acids.

Process of Oil Filter Powder Coating

1. Pre-Treatment: The oil filter is cleaned to remove any dirt, grease, or other contaminants.
2. Application of Powder Coating: The powder coating is applied to the oil filter using an electrostatic gun. The gun charges the powder particles, which then attract to the grounded oil filter.
3. Curing: The oil filter is placed in a curing oven, where the powder coating is heated to a specific temperature for a specific time. This allows the powder particles to melt and flow, creating a durable finish.

Environmental Benefits of Oil Filter Powder Coating

1. Solvent-Free Process: Powder coating is a solvent-free process, which means that it does not emit any harmful VOCs (volatile organic compounds).
2. Reduced Waste: Powder coating systems are designed to capture and reuse overspray, which reduces the amount of waste that goes to the landfill.

Conclusion

Oil filter powder coating is a durable, environmentally friendly, and cost-effective way to protect oil filters from corrosion and other damage.

Surface Pretreatment

Surface pretreatment with tunnel-type washing booths is used in automatic powder coating systems. Here the parts are hung on a conveyor line and are carried through the tunnels in which there are spray nozzles, spraying chemical compounds on parts. The tunnel is called a degreasing tunnel, rinsing tunnel, phosphating tunnel and etc.

Surface pretreatment tunnel construction

The tunnel body is comprised of panels made of AISI 304 /1.5 mm of chrome metal sheet installed on a carrying lower portion fixed on the tanks through welding. The lower portion was welded whereas the panels were mounted with bolts. A special mastic resistance against chemical materials was used between the panels Two parts of the body which are degreasing processes were insulated with 50 mm of glass wool and all processes were
coated through 1 mm of metal sheet panels with powder paint. There are breakers in the tunnel so as not to let the chemicals released from the nozzles mix with each other and the ground of the dripping zones are as inclined as it must be.

Brushes over the tunnel

Through the tunnel, brushes were used over the upper aperture of the injection tunnel. The brushes were made of a material that is resistant to both temperature and chemicals.

Lighting

There are temperature-resistant lighting lamps, which are located in the surface pretreatment line.

Tanks of the Surface Pretreatment for Powder Coating

The tanks were made manufactured through welding from the AISI 304 /2.5 mm of chrome metal sheet; the outer surface is reinforced; the ground parts are inclined towards both the central point from the sides and towards the discharge point, and there are discharge pockets; there are also charging valves and butterfly-type discharge valves that allow discharging the content in 30 minutes at most.

There are anti-overflow units, which are placed in a lengthwise position, on all tanks and there are also caps over the upper section from one end to the other (they are the same both in and outside) as well as grids so as not to let the falling parts fall into the tank.

Valves, Manometers, Filters

There are “Butterfly (Throttle) Valves” that are used to adjust the flow and pressure, in all inlets and outlets of all pumps and there are also manometers, which are used to indicate the pressure, in the pump outlets and removable filters made of stainless steel, which are used not to let the big grains reach the pumps and which are available in the tanks

Heat Exchangers of the Tanks of Surface Pretreatment for Powder Coating

The bathtubs are heated through the heat exchangers with a burner installed in the tank. The burners operate automatically considering the operating temperature set and keep the bathtub temperature at a constant level.

Spraying System

The liquid absorbed from the tank is transferred to the injection nozzles through a centrifuge-type pump. All connection pipes, collectors, and nozzle pipes were made of pressure-resistant pipes. Besides, nozzle pipes (rings) were designed so as to allow removing and cleaning of the parts independently. Nozzles have a 60º of angle; their heads are also mobile; their injection direction is adjustable and they also have a dual pipe clip type. All injection nozzles were made of stainless steel material in accordance with AISI 304 Standard.

Drying Oven for Oil Filter Powder Coating

The drying oven is equipped with a heat generator that heats the air inside the chamber to the desired temperature, thus drying liquid paint or curing powder paint.

The ovens are equipped with a heat generator that can be either direct or indirect exchange, which allows the desired temperature to be reached within the baking or drying chamber. Pieces coming from other stages of processing, such as washing or painting, are fed into the oven via an overhead conveyor or other means of transport.

The temperature inside the oven is reached and maintained at a constant setpoint throughout the baking cycle, thanks to a temperature regulator located in the electrical panel and a temperature probe inserted inside the baking chamber. EMS drying and curing ovens can reach a maximum temperature of 350°.

Our standard curing and drying ovens have a temperature range of + or – 2°C. For the aeronautic industry or other critical application areas, we can narrow the range down to + or – 0.5°C.

Customized drying and curing ovens

EMS manufactures custom drying and curing ovens in order to solve any problem related to drying and curing objects of any size.

Our ovens are designed and built according to your actual dimensional, technological, process, or production requirements. In fact, EMS Powder Coating Quipment realizes baking and drying ovens that can be customized in size and shape (in case of space problems) and can have:

• 2 or 4 shutter-equipped closing portals with sliding doors,
• side doors,
• portholes with internal lighting,
• graphic recorder with several temperature probes,
• stainless steel inner chamber,
• and other features according to your specific needs.

Energy-saving and heat recovery systems

Ovens are composed of a heat generator inside which there is a burner, generally gas-fired. The latter heats the air taken from the baking chamber through an aspirator which then feeds it back into the oven’s plenum. Here the air is mixed and introduced, from the top to the bottom, inside the treatment chamber.

In EMS ovens, the hot air inside the baking chamber is constantly recirculated.  This solution allows you to keep the temperature constant over time with the minimum possible energy consumption while also ensuring an even distribution of the air at the same time. Moreover, at the end of the firing cycle, in order to allow the pieces to be unloaded from the oven, an aspirator moves the hot air outside, which can be then used to feed a heat recovery unit.

The insulation of the ovens is realized with high-density mineral wool, whose thickness varies from 50 to 150 mm according to the temperatures to be reached during the expected working cycle. Eurotherm’s particular construction technology without thermal bridges guarantees an effective barrier against heat dispersion as well as considerable energy saving.

Drying oven with airstream combustion (direct exchange)

In ovens with airstream combustion, the burner flame is in direct contact with the air within the cooking chamber.

For this reason, it is most suitable for baking powder coatings (polymerization) and water-based liquid coatings.

The main advantages of using an oven with airstream combustion are:

• Affordability of the operation.
• Speed of reaching the designated temperature.

The main sources of fuelling are methane gas, LPG, and diesel.

Drying Oven for oil filter powder coating

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.

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.
