FAQs – What is the purpose of powder coating?

Powder coating is a paint finishing process that is applied to metal surfaces. A powder-coated surface will be more resistant against corrosion, scratches, wear and tear, chipping, and fading. TD Finishing powder coating equipment is used to paint everything from bicycles to car parts and domestic boilers to Architectural aluminium. 

FAQs – How much does a powder coating system cost?

Finding out how much a powder coating system can cost is not a simple task. However, here at TD Finishing, we will talk you through all of the most suitable options. We will equip you with everything you need to know. Then, together we can make a decision on what system will be best for your business. If you are a small start-up business you are probably looking for a budget batch-system. You can purchase these for as little as £40,000-£50,000. For a large scale business, you will be looking at around £400,000 to in excess of £600,000+. A higher continuous-production can put the cost of a facility into millions of pounds.FAQs

FAQs – How does a powder coating system work?

As with any finishing process, it is imperative that the metal part is clean and free from grease or contamination to ensure that a good adhesion is achieved. 
The first stage in a powder coating system is the pre-treatment process. This cleans and prepares the metal through the use of specialist chemicals and purified water. Pretreatment can be performed by spraying or dipping the part in the chemical solutions.

Once cleaned, the metal has to be dried in a drying oven where heat is used to evaporate any moisture which could lead to premature corrosion.

After drying, the product passes to the powder coating booth where the paint can be applied.
Powder coating works by applying paint powder directly to the metal surface. Then using an electrostatic charge to attract the paint powder to the metal product.
At this point, the powder does not form a protective barrier, and can be easily wiped off. 

The painted part is then baked in an oven which causes the paint powder to ‘flow’, providing a uniform thickness of paint. As the product cools, a hard and durable finish is formed.

FAQs – Is Powder Coating expensive?

Whilst powder coating components can cost more than traditional wet spray paint applications, the benefits often far outweigh the initial costs. Factors such as improved quality of finish, reduced reject rates & increased product lifespan all fall in favour of powder coating.

Turnaround times of powder coated parts are reduced as parts can be assembled and packed as soon as they have cooled post curing. This allows for  less inventory to be held and faster response times. 
Oversprayed powder can also be collected and recycled instead of wasted. This increases coating material utilization rate, and lowering the cost of materials over time.

FAQs – How long does powder coating last?

The durability of powder coating is unmatched. Its resistance to wear, UV light & moisture mean that a powder coated part with the correct pretreatment can last over 25 years. With different pretreatment processes, Powder coated parts can be used both internally and externally.   

FAQs – Why is powder coating better than paint?

Powder coatings can be applied in a wide range of colours, textures and finishes that can often not be achieved through conventional wet paint systems. A more durable coating can be applied which is less prone to chipping, impact and wear, making them more suitable for high traffic applications.

From an operational standpoint, powder coating uses no solvents or volatile organic compounds (VOCs). Therefore considered far safer and environmentally friendlier than traditional wet spraying.
