The FINISHING PROCESS ALUMINIUM EXTRUSION PROFILE
Finishing is done after the aluminum extrusion process. Aluminum extrusion is the process of transformation of the alloy of aluminum into various objects of different characteristics depending upon the use. The malleability and ductility help the metal to cast into the unusual shape and aids in the flexibility. There are many options for the finishing of the aluminum extrusion profiles, and amongst them, the powder coating is one of the best options. The powder coating is the effective one, durable and the feasible alternative. The powder coating prevents corrosion, heat, and cold to increase the durability. In aerospace, and furniture
A coating on aluminum extrusion profiles requires a stepwise process.surface is checked to see any damage. Proces can primarily be defined into three steps.
The pretreatment
The surface before the coating is checked to see the damage. The dust particles, grease, and any other foreign material are removed using chemicals and other mechanical methods. The surface is cleaned adequately for better adhesion and to prevent any flaking. The pre-process treatment is the critical process, and it ensures the longevity and the durability of the products.
Application of the coating and the curing of the surface
.The powder coating is applied from the electrostatic spray gun, the mixture of layer consists of the resin and the color pigments. The positive charge is given to the powder, and this attracts the negative charge of the surface. The electrostatic disc methods and the electrostatic, magnetic brush are the other powder coating method.
After the application of the powder, the object is cooled in the oven and powder melts uniformly and forms a thick coating when it gets cooled down.
Product finishing is important. Aluminum extrusion profiles are coated with powder coating, and this provides the durability and protection from any damage.
