Powder Coating
Powder Coating; ERD Metal can produce a long line of powder-coated materials, all of which are in accordance with Qualicoat standards. We have a renewed powder coating line that allows us to achieve high-quality surface finishes to exceed all customer expectations.
What is Powder Coating?
Powder coating is the finishing process where dry, free-flowing, thermoplastic powder is applied to a surface, melted, and evenly hardened into a coating. This is an extremely diverse practice as it can be applied to several materials, including metals, plastics, glass, and more. Once the process is carried out, it is both functional and decorative and can be coated with a wide range of colors, finishes, and textures otherwise not available when using conventional liquid methods.
There are two main methods of powder coating, namely electrostatic spray deposition (ESD) and fluidized bed application. Both methods produce even, hard finishes and are more cost-effective, durable, and environmentally friendly than liquid applications.
Powder Coating How it Works?
There are three stages to powder coating, each requiring a set of materials and equipment indicative of its characteristics. Once we’ve completed these stages, the result produces a durable, high quality surface finish. These stages include:
Stage 1: Preparation
The surface of the substrate is cleaned and treated to remove any dust, dirt, and debris. Any residue could affect the adhesion of the powder as well as the result and quality of the final finish.
Stage 2: Application
The coating material used determines the application method – electrostatic deposition (EDS), or fluidized bed powder coating. The EDS method is used on metal parts and takes place in a powder spray booth, powder feeder, with an electrostatic spray gun, and a power gun. With fluidized bed, the preheated parts are dipped into the powder material.
Stage 3: Curing
The method used in the powder coating determines the curing process. If the EDS method is used, the powdered parts need to be cured in a powder curing room. If the fluidized bed powder coating method is used, the parts are heated in similar ovens used in the EDS method.
