We installed a state-of-the-art Gema paint line last year that we use to deliver our premium powder coating in Suffolk. These services are some of the best currently available, as this semi-automated paint line offers a reliability that can’t be achieved manually. The Gema paint line has four main stages when powder coating an item:
The pre-treatment of metal before applying a powder coat is absolutely essential as any oil residue, dust, or other foreign particles can cause the powder to not properly apply. This can cause both imperfect finishes and the early breakdown of an otherwise very durable finish.
This is why the 3-stage pre-treatment process is so essential. First, we degrease, then use phosphate wash, then do a double rinse to ensure a perfectly primed surface.
This stage ensures that all the liquid we used to clean the sheet metal has evaporated, ensuring that its ready for colouring.
Applying an even powder coating involves using an electrical current in the work piece and electrostatically charged powder. This ensure that the powder sticks to the work piece until it can be cured into place but also assists in creating an even coating across the whole product.
The final stage is curing the powder. By heating to around two hundred degrees Celsius, the powder reacts chemically to form long molecular chains that are extremely strong. These molecular chains are what puts a powder coating above standard wet paints in terms of durability and resilience.
In addition to powder coatings brilliant endurance in the face of erosion, dings, and scratches, it is an incredibly time efficient process. Once the item has cooled after curing it is ready to go. This is a bold different when some wet paints require multiple coats with lengthy drying times.
