Metal Finishing Varieties

NADACP metal finishing is an industrial process by which the exterior of a metal product is treated by means of applying a thin matching layer to its surface. There are several types of NADCAP metal finishing processes and every one of them is employed for a different purpose. For every type of metal finishing process there are a number of factors and applications that ought to be considered. However, at the end of the day, when NADCAP metal finishing treatments have been accomplished, there are a number of tangible benefits that are received such as enhanced durability, more decorative appeal, improved electrical conductivity, greater electrical resistance, greater chemical resistance, greater tarnish resistance and vulcanization potential.

Metal plating: Electroplating service is done using plating machines that use a chemical bath for the process of coating or modifying the substrate with a thin layer; a good example is the nickel PFTE plating. To coat the substrate using the electroplating method produces an electric current, whereas electroless plating uses an autocatalytic process wherein the substrate catalyzes the reaction.

As a finishing process, nickel ptfe plating comes with a host of advantages. It can enhance a product’s corrosion resistance, durability, exterior look and surface friction. It can be useful in coating other metals as well. A barrel-finishing machine performs fast and efficient plating during high-volume production runs.

Brushed metal: Another variety of NADCAP metal finishing is known as brushed metal finishing which is very effective in the removal of surface defects. The machines that are used for this kind of process produce an even, parallel grain texture to smooth out the exterior of a product. To come up with this effect, it uses a wire brush or abrasive belt. Moreover, the singular direction of the brush or belt can produce slightly curved edges that are vertical to the grain.

Buff polishing: This process is best for decorative items since it enables them to look smoother and more lustrous. Buff polishing machines have a tendency to make a product rounder at its edges. Due to the limitations of the cloth wheel range, they are not too effective for applications that require fragile and intricate features.
