Metal finishing is used to treat the exterior of a metal product by applying a thin complementary layer to its surface. There are numerous types of metal finishing processes that can be used for a variety of purposes.

A brief introductory note is penned out in following section to get clear notifications about all the above mentioned types of metal finishing.

Metal Plating is a technique where chemical bath is used to coat or alter the surface of a substrate with a thin layer of metal, such as PTFE or nickel. The electroplating technique produces an electric current to spread the substrate, while electro-less plating occupies an autocatalytic practice where the substrate acts as a catalyst in the reaction.

Brushed metal is a technique for removing surface imperfections. These finishing machines create a uniform, parallel grain surface texture to smooth out a product’s external look.

Buff polishing method tends to round out a product’s edges, and but due to the cloth wheel’s range limits, this method is less effective for applications requiring complicated, recessed or fragile features.

Metal Grinding is a technique used to employ attrition, friction and/or compression to smooth out a metal product’s surface. Mostly all metal grinding machines consist of a substrate within a rotating drum.

Metal Vibratory Finishing machines are used to expel products and remove sharp edges. They place material inside a drum packed with abrasive pellets and a substrate, then apply dipping vibration to create a uniform random surface. The machine’s cycle speed and magnitude of vibration are usually variable, allowing effective treatment for a range of small-sized to large- sized parts.

Sand Blasting machines are naturally engaged in projects requiring a uniform non-glossy texture. The process (also recognized as bead-blasting) forces sand, steel shots, metal pellets or other abrasives into a substrate at high speed. This results in a smooth, clean product texture, particularly in soft metals.

Powder Coating applies a decorative finish that is similar to paint, but with superior durability. The process entails melting dry synthetic powder onto metal to create a matte, glossy or textured coating. A machine for textured powder-coating is also extremely efficient in removing surface defects.

Hot blackening machines spread a thin layer of black oxide onto a product’s surface to create a matte black finish with high abrasion confrontation. It is a high-temperature course in which the product is inserted into a series of tanks containing caustics, cleaners and coolants.
