The prep is essential, but so is the right equipment! Isn’t it? The Questions that might quickly arise is- What Equipment is required for powder coating? How are these divided into t6he various stages?

The first step is to clean and prepare a product (usually a metal part) for coating. Then dusted with a powder on the surface of the part. Finally, the part is placed in a curing oven. After that, the material is heated in the oven, causing the powder to melt and flow, resulting in a uniform coating. When the melted powder is cooled and hardens, it forms an imperishable and appealing coating.

To  powder coating, we must have three types of powder coating equipment:

Preparation (where your product is cleaned before powder coating)

Application (where the powder is sprayed on the material)

Curing (where the powder is cured into an imperishable finish)

Pretreatment For Powder Coating

Pretreatment equipment is used before the material is powder-coated to ensure that the material is ready for the further process, i.e., the powder application (which is an essential step. If the product to be powder coated contains a lot of debris (rust, laser scale, pre-existing paint), a Blast Room will most likely be required.

A blast room is a room that is used to push ahead polishing material against the surface of your parts using compressed air. Depending on materials, you would typically like to use an appropriate blast media (grit) or steel shot to wash off all unwanted materials from your part until it is a clean metal surface that is ready for powder coating.

If oils, solvents, or chemical residue cover any part of the surface of your material, it is always safe to go with a wash station. You will spray your material with cleaning agents or with a chemical pretreatment agent in the wash station, such as iron phosphate. Even if the parts have already been blasted, the wash station can help you improve powder to stick will on the material and have a polished look.

Pretreatment requires the utilization of a dry-oven in certain operations. This is quite similar to the curing oven, but it is heated to evaporate any water or chemistry. This step can also help parts achieve an optimal powder application temperature.

Application: Powder Guns and Powder Spray Booths

Almost always, a special powder spray weapon is used for powder coating application. The powder should be electrostatically charged to make powder coating work efficiently. A spray gun exclusively designed to be powder coated is the only way to apply this charge. The powder is moved to a container by compressed air or directly from the box into which the powder is stored.

The compressed air blows powder as a densely formed cloud from the weapon. When the powder leaves the weapon, the electrostatic charge is received. When the powder cloud is charged, it envelops the part and sticks to the ground part surface (which is why powder coating equipment is so easy for freshmen or non-experienced to use).

You’ll have to have a place to use your powder weapon. If you sprinkle powder, you get some powder on the floor and in the air rather than on your products. The remaining powder is called an excess powder. The retention of this spray is one the use of the Powder Spray Booth.

Powder cure: powder sheaths

The last step is to insert your product into a specially designed Powder Curing Oven after powder-coated. They usually run from 325° to 450° Fahrenheit. The temperature stabilizes as soon as the oven reaches a temperature. The coated products shall be exposed for a certain period to precisely heated air.

After the process of curing has been completed, the parts are removed and cooled before handling. Electric furnaces or gas or LP-fueled heat systems are used for ovens. These standard ovens usually rely on heated air moving over the convection curing elements.

The type of oven you choose is critical if you want to make a powder coat professionally. Brand name powder curing ovens are designed to produce premium coating results and highly efficient devices in fuel consumption and energy costs. You will probably be using your oven several hours a week, so your profit is quickly reduced by the price of an inefficient design.

Powder Coating Layouts Professional Systems

An automated powder cover Line uses the same equipment as a batch system but connects several or all of the steps through a motorized transport system that constantly moves the parts through. The products are typically placed on the conveyor at a set location and moved through each step. The parts are clean, prepared, and powdered by manual operators or automated appliances. After the parts are coated, they travel through the healing oven to a point where they can be unloaded.

Selection of Industrial Powder Coating Equipment

What do you think of a good powder coating gun?

1. Consistent gun tip tension of 100KV.
2. Uniform powder flow for consistent deposition
3. The machine should be operational and maintainable easily. To get spare parts and support in due time, the manufacturer or his representative should be accessible at a reasonable price.

Preparation: To see whether the material requires blasting or washing, or both? If yes, then you will need a blast booth or wash booth or maybe both.

Preheat/Dry: What does the material require to preheat the material using pretreat drying, process, or outgassing? If yes, then decide whether you need an extra oven or if your cure oven can do so.

Parts and racks in size: The size of your appliance and the workflow requirements are determined here.

Available Area In Shop: This determines whether you need extra space or how much equipment you can fit.

Parts per day: Determines the number of stalls and stoves you need to meet your current and future production objectives.

Therefore, the selection of industrial material coating powder depends on our requirements and conditions, depending on the material being used.
