Application

  • Architecture Parts
  • Electronic Parts
  • Die-cast Parts
  • Automotive Parts
  • Metallic Furniture Parts
  • Metallic Cookware Parts
  • Medical Parts
  • Defense Parts
  • Mechanical Parts

1.Powder spray booth

a. Working principle

There will be an electrostatic field developed between the parts and the powder spray gun during the powder spraying process.

The charged powder particles will go through the nozzle gun and get settled on the part surface.

This is because the powder particles will be given a positive charge and the parts will be given a negative charge or grounded.

Thus, there will be an attractive force between the opposite polarities.

If these positive and negative charges are within an electrostatic power field, then you can get the best coating results.

b. Equipment components

The different components of the powder spray booth are the powder spray gun, pulse control device, air absorbing device, cabinet, filter recovery device, electronics part for control, and small cyclone system.

All these parts are industrial grade ones.

c. Main structure

High quality and sturdy steel plates and square tubes are used for the manufacturing of the powder cabinets.

Durable and imported fiber is used for the filters in the filtration system.

The recovery system makes use of a first grade device.

The additional sprayed powder is recollected with the help of a filter element and a small cyclone system along with a fan.

The recoil electromagnetic pulse valve in the system is responsible for the procurement and return of the powder into the recycling cabinet.

It supports a recovery rate of up to 95 percent.

Another interesting feature of the powder spray gun is that it comes with a unique power output that ensures that doesn’t get discharged even at high voltages.

2. Powder curing oven

The drying of the powder sprayed on the part surface is facilitated by the powder curing oven.

It provides sufficient space to keep the parts for curing.

a. Working principle

The circulating air is ventilated first by the centrifugal fan first during the powder curing process.

This air will then enter into the heating furnace via the backwind tube.

The indirect exchange of heat will happen during this process.

The hot air required for the heat exchange is generated by the burning gas.

b. Equipment components

It is the centrifugal fan that ventilates the circulating air first during the curing process.

The air goes through the backwind tube and enters the heating furnace.

The indirect heat exchange takes place here.

The burning gas is responsible for the generation of the hot air that is required for the heat exchange.

The hot air goes through the blast pipe and enters the drying cabinet.

This air is used to dry the parts from top to bottom.

A new cycle is started with the entry of the heated air into the backwind tube at the bottom from the return inlet.

The cycle pipe will open with the presence of fresh air from the supplementary inlet and the waste air exhaust vent.

3. Conveying appliance

The conveying appliance comes with a hanging chain and an electric hoist.

person spraying powder coating

 

Cleaned parts will be moved to the powder spray booth.

Here, the powder will be applied to the parts.

A positive charge will be given to all the powder particles with the help of the powder spray gun.

The spray gun will spray a fog of powder around the part surface with the help of the air compressor.

The parts will either given a negative charge or grounded.

So, the oppositely charged particles will get deposited on the part surface because of the electromagnetism phenomenon.

The excess powder will settle on the ground.

It will be collected and reused for the next process.

The sprayed part will be moved to the powder curing oven through the conveyor.

Here, the parts are subjected to certain high temperatures for the powder to stick to the parts.

The curing temperature and dwell time for the process will vary for different parts and different powders.

You will get the coated part with the desired finish at the end of this process.

20.Why Should Aluminum Profiles Be Powder Coated?

We use aluminum profiles in different places.

Aluminum profiles are used in structure walls, doorways, home windows, and other structures.

Some of the properties of aluminum are preferred for these use cases.

The ease of the process and the small specific gravity are the two main features of the aluminum part.

The silvery shine on the aluminum is another feature.

A pure aluminum part is resistant to corrosion.

The formation of the oxide layer on the pure aluminum part protects it from corrosion.

You will get multiple grades of aluminum.

powder coating process

 

Aluminum is a weak metal and does not offer good mechanical strength.

It is possible to increase the mechanical strength of aluminum by converting it into an alloy.

You can add different elements into aluminum like magnesium, copper, and zinc to convert it into an alloy/

Now, the aluminum part is susceptible to the oxidation effect due to the mixing of other elements.

So, you will have to powder coat the aluminum alloy part to protect it from corrosion.

Different colors can be given to the aluminum part with the help of the powder coating process.

So, it will make the part look more attractive.

These are the major reasons for powder coating aluminum parts.

You can really enhance the life of aluminum parts with the help of the powder coating process.
