Powder Coating Non-Ferrous MetalsSeptember 16, 2016
Special finishes are often applied to non-ferrous parts at the post-processing stage. There are extra polishing and machining stages here, plus electroplating techniques and other finishing processes. They refine the component and improve key surface properties, but powder coating technology goes beyond such functional finishing work. The dry powder, as it melts in an oven, creates an inviolable membrane, a finish that's as durable as it is beautiful. Available in myriad textures and polished veneers, iron-free metals gain reinforced properties when processed in this manner.
What is Powder Coating
The resin-packed powdery substance is loaded with thermoplastic strength, although thermosetting variants are available. Electrostatic charging is used to uniformly coat the metal component in the powder, at which point it's conveyed into a heated oven. The powder mix now melts and flows to create an impenetrable shell. Of course, this is a barebones description of a technologically advanced process, one that offers turnkey advantages and an eco-friendly environment, as every element of the work is concluded in spray cubicles and a sealed oven, but this outline does serve to illustrate the effectiveness of the post-finishing process.
Amplifies the Positive Properties of Non Ferrous Metals
The corrosion-resistant characteristics of a high-quality iron-free metal are already well documented, but this coating pushes that property sky-high by eliminating all potential oxide formations. Similarly, differently graded aluminium alloys deliver contrasting strength profiles. This finish reinforces that already respectable strength level by adding its own robust shell-like outline. Contemporary processing stations are also programmable, so the thickness of this tough membrane can be controlled. Modern variants are applied by powder finishing guns and drop baths, so the finish is actually managed by the electrostatic power supply, a device that can reduce the thickness of the coating to a couple of millimeters while maintaining a satisfactorily high impact-resistant quotient.
Castings Benefit from Post-processing Refinements
Granular resins live companionably with polishing stations and sand blasting chambers to create an expanded range of client-specified finishing services. Of course, the benefits associated with a dry powder finishing station are a little different, as they emphasize numerous aesthetically rich options, including chrome-like patinas and textures that age the metal for decorative purposes.
The ovens and electrostatic gear installed at the terminating end of a castings factory are readily available from many respected manufacturers, so non-ferrous metals can be armoured with exceptional strength, weatherproofing capabilities, and good looks while simultaneously adhering to an eco-friendly processing format.
