Fabricated Products offer two Painting Processes; a conveyor coating plant and a batch process plant for powder and wet spraying.

Conveyor Coating Plant

The conveyor-operated powder coating plant facilitates larger batches of components to be processed efficiently in a full range of colours and finishes.

Process 1

Components are masked and hung on a monorail overhead conveyor.

Process 2

Components now pass through a six-stage pre-treatment process to ensure that they are fully degreased and phosphate-coated to give excellent paint adhesion. SPC controls are used throughout these stages, which include;

Stage1. Degrease with an alkaline cleaner Auxiclean CL361. This dissolves oil and grease
and carries them away with it, to create sludge, which is removed from time to time.

Stage 2. Initial cold rinsing with water.

Stage 3. Another cold rinsing to eliminate any remaining alkali.

Stage 4. Apply Novaphos F50. This is a metal phosphate pre-treatment used to improve paint
adhesion on metal and increase corrosion resistance.

Stage 5. Final cold water rinse

Stage 6. Passivate with Deoxylte 7100. As the component is now extremely clean, it is highly
susceptible to rust. Deoxylte 7100 minimises this risk.

Process 3. 

At this stage parts are dried in an oven at 180°C, in preparation for the application of powder.

Process 4   

Parts travel through the spray booth and automatic electro-static spray guns apply measured amounts of powder. This automated system is supplemented by manual application of powder e.g. for surface areas that are not easy to reach. Any excess over spray is re-cycled through a recovery system, to minimise environmental consequences.

Process 5.

The last stage in this process is the curing oven which melts the powder coating onto the part, giving a strong, high-quality finish.

Batch process plant for powder and wet spraying.                           

A manual spray booth is used for both smaller batches and for larger individual components to be processed.

Quality Checks

A number of quality checks are implemented into our paint and powder processes and these include a thickness test to ensure that the density of coat is sufficient, visual checks to confirm a smooth finish and an impact test to ensure the powder adhesion is strong.
