Selecting the Best Powder Coating Equipment and Its Advantages

Powder coating is the newest alternative painting method for better finishing. This process is very similar to dry paints. In this method, the polymer granules are produced from medium-density fiberboards, aluminum, acrylics, and fusion-bonded epoxy. They are then fused with pigments and powder elements to get the colors.

So, now you might wonder what precisely this powder coating equipment is. These pieces of equipment are nothing but a type of coating apparatus that is used for applying powder without involving any solvents. The coating is done by the electrostatic technique, which is further passed through heat so that the powder starts flowing to form a skin. It can either be a thermoplastic or a thermoset polymer. This painting method is mainly used for painting over metals like household appliances, bicycle parts, aluminum extrusions, etc. for a harder finish than the conventional way.

Advantages

Some of the benefits of powder coating process are as follows:

1. Coating the metals reduces the emission rate of volatile organic compounds

2. It facilitates cent per cent reusability of the substance, as it can be recycled

3. It can produce a lot thicker coating than the liquid coating, especially on metals

4. The operating cost for this method is lower than the traditional method

5. It is way less hazardous and reduces the waste as compared to the liquid lines

Powder Coating Equipment and Processes

At the very beginning, before proceeding for the powder coating, it is essential to remove the grease, oil, mud, metal oxides, etc. from the surface This step is called the pre-treatment or part preparation. There are many methods – chemical and mechanical for the removal process, depending upon the requirement of the finishing of the product.

Among the many types of powder coating equipment used in this method, there are different types of guns that are used to cast the powder on to the object’s surface.

1. Corona charging-gun: It uses electronic power for producing charge on the powder. These guns are also known as electrostatic guns. After air-spraying the powder, the object is first heated to melt the powder for making a uniform film and then cooled again to create a hard coating.

2. Tribo charging-gun: It uses the power of triboelectric friction between the powder and the gun’s barrel to produce the charge for the powder instead of using electricity. The powder used in this technique needs a different formula from the corona gun.

3. Bell charging-gun: It projects the powder from the outer edge of the bell that produces the electrical charge in the powder.

There is another method called the fluidized bed method for powder coating. Most of the dishwasher racks we get in the market are coated using this method.

How to Choose the Best Powder Coating Equipment?

1. At the very beginning, ask yourself why you are buying the equipment. Make sure which one will be more beneficial for you, powder coating the work by yourself or by contacting the professionals. If you doubt yourself for having the expertise to perform such tasks or lack enough space to carry out the work, then you should reach out to the certified professionals for the best results.

2. Find out a uniform powder flow so that it sits on the surface uniformly.

3. Consider the ease of maintenance and the handling process of the equipment.

4. Evaluate the buying cost and the general maintenance cost and ensure that it satisfies the total ownership cost budget.

Final Thoughts
