- Metal Finishes
- Metal Plating
- Metal plating machines use a chemical bath to coat or alter the surface of a substrate with a thin layer of metal, such as nickel or PTFE.
- Electroless-plating
- Electroless plating employs an autocatalytic process in which the substrate catalyzes the reaction.
- Advantages: Improves durability, corrosion resistance, surface friction, and exterior appearance. In high-volume production runs, a barrel-finishing machine is a fast and efficient plating solution.
- Generates an electric current to coat the substrate
- Disadvantages: Generally not suited for smoothing out surface defects.

- Buff Polishing
- This machine uses a cloth wheel to buff the product’s surface
- Advantages: smooth, non-textured finish, high, glossy sheen
- Disadvantages:Buff polishing machines tend to round out a product’s edges, and due to the cloth wheel’s range limits, the process is less effective for applications requiring intricate, fragile, or recessed features.

- Brushed Metal
- Advantages: An abrasive belt or wire brush is usually employed to achieve this effect. In addition, the singular direction of the belt or brush can create slightly rounded edges perpendicular to the grain.
- Disadvantages: Unlike plating, brushed metal finishing is an effective method for removing surface imperfections. These finishing machines create a uniform, parallel grain surface texture to smooth out a product’s exterior.

- Metal Grinding
- Grinding machines use friction, attrition and/or compression to smooth out a metal product’s surface. There are several types of grinding machines designed to deliver different levels of finite smoothness. For example, a ball-grinding mill is an excellent fine grinder for cement products, but may not work for more extensive smoothing projects.

- Metal Vibratory Finishing
- Vibratory finishing machines are used to deburr products and remove sharp edges. They position material inside a drum filled with abrasive pellets and a substrate, then apply tumbling vibration to create a uniform random texture. The machine’s cycle speed and magnitude of vibration are usually variable, allowing effective treatment for a range of small- to large-sized parts.
- Sand Blasting
- Sand-blasting machines are typically employed in projects requiring a uniform matte texture. The process forces sand, steel shots, metal pellets or other abrasives into a substrate at high speed.
- Advantages: Results in a smooth, clean product texture, particularly in soft metals.

- Powder Coating
- The process involves melting dry plastic powder onto the metal to produce a textured, matte, or glossy coating.
- Advantages: Applies a decorative finish that is similar to paint, but with greater durability. A textured powder-coating machine is also highly effective in removing surface defects.
- The process involves melting dry plastic powder onto the metal to produce a textured, matte, or glossy coating.
- Hot Blackening
- Hot blackening machines spread a thin layer of black oxide onto a product’s surface to create a matte black finish with high abrasion resistance. It is a high-temperature process in which the product is inserted into a series of tanks containing cleaners, caustics, and coolants. Hot blackening is most commonly used in the production of automotive parts, tools, and firearms.
