Anodize Type II: Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Under the corresponding electrolyte and specific process conditions, and the effect of the external current,aluminum could form a layer of oxide film on aluminum products.

Hard Anodize Type III: The process of hard anodizing is similar to anodizing. It is to reduce the dissolution rate of the film when aluminum part is anodized and obtain a thicker and denser anodic oxide film. This more thickness could improve the corrosion resistance, wear resistance, weather resistance, insulation and adsorption of aluminum parts.

Alodine: Alodine is a chromate conversion coating that protects aluminum from corrosion. The process is very simple, requiring only 3 minutes of immersion to complete the process, with no equipment. The alodine process is currently one of the most suitable processes for the surface oxidation treatment of CNC aluminum parts.

Sand-Blasting:Sandblasting (also named bead blast) is a very common kind of surface finish used for CNC machining aluminum parts. Sandblasting is the process of smoothing and cleaning a hard surface by forcing solid particles across that surface at high speeds using compressed air. People usually use mesh to decide the size for the sandblasting.

Brushing: Brushing surface finish is formed a very fine line pattern on the surface of the metal parts by grinding the product to provide a decorative effect. According to the different surface line patterns, there are three types of brushing surface: straight pattern brushing, messy pattern brushing, corrugated pattern, rotary pattern brushing.

Chromate Plated: Chrome plating involves applying a layer of chromium to a surface by submerging it in a chromic acid solution. It is more than just an aesthetic enhancement, although it does look pleasing to the eye. Chrome plating can increase the hardness and durability of the surface, prevent corrosion and even make it easier to clean. There are two types: hard chrome plating and decorative chrome plating.

Passivate: Passivation is a widely-used metal finishing process to prevent corrosion. In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion.

Phosphate Plated: Phosphate coatings are a crystalline conversion coating for steel and other metals that is formed on a ferrous metal substrate. The process is to immerse the steel parts in a phosphate solution to obtain a layer of water-insoluble phosphate film on the metal surface.

Electrophoresis: Electrophoresis coating (Also known as e-coating or electro-coating) is a painting process that parts are immersed in a paint solution contained in an electrified tank. The paint in the solution exists as ions with a positive or negative charge. When the parts are immersed in the tank, the paint migrates to the surface of the part. The paint ions gain or lose electrons at the surface of the part and are changed to solid paint that attaches to the surface. Normally the color is black or grey. It is generally used as a primer coating for metal products such as auto parts and hardware.

Tumbling: Tumbling finish is a process to remove the sharp edges, burrs and make a smooth surface for metal and plastic parts. There are two types of tumbling finish: Vibratory Tumbling and high energy tumbling finish.

Zinc Plate: Zinc Plating is a widely available solution for protecting steel parts from corrosion. It is commonly chosen because it is cost-effective, offers excellent corrosion protection and features an attractive blueish/silver appearance. Zinc plating is the process of covering substrate metals (like steel and iron, etc.) with a layer or coating of zinc to protect the substrate from corrosion. There are two types of zinc plating: Hot-dip Galvanizing and Cold Galvanizing.

Nickel electroplating: Nickel electroplating is the process of applying a nickel coating onto a metal surface by means of electrolytic deposition. In order for parts to be plated, they must be clean and free of dirt, corrosion, and defects so the plating can be applied. In order to prepare a product, it must be cleaned and protected before the plating process. To prepare a part, a combination of cleaning, masking, heat treating, pickling and etching is commonly used.

Nickel Electroless plating: Nickel Electroless Plating is a process that deposits an alloy of 90% nickel and 10% phosphorus on a wide range of metals. It provides additional wear- and corrosion resistance, lubricity, and ancillary performance characteristics compared to its electrolytic counterpart.

Power Coating: Powder coating is a dry coating process used as a metal finish mostly on industrial equipment. Powder coating is applied as a dry powder through an electrostatic process, then cured with heat. It is well known for providing high-quality finishes in terms of both functionality and overall look.

Black Oxided:  Black oxide (blackening) is a conversion coating that is used for appearance and to add mild corrosion resistance and minimize light reflection. The principle is to produce a layer of oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. It is used for ferrous materials, zinc, copper and its alloys, silver solder and powdered metals Black oxide is impregnated using oil and wax to achieve maximum corrosion resistance. It also provides a deep black color when used with proper post dips.

Electropolishing/Polish: Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel. The process leaves a shiny, smooth, ultra-clean surface finish.

PVD Vacuum Plating: Physical vapour deposition (PVD) is an industrial manufacturing process that mainly uses physical processes to deposit thin films.PVD Coating refers to a variety of thin-film deposition techniques where a solid material is vaporized in a vacuum environment and deposited on substrates as a pure material or alloy composition coating.

As Machined: Our standard finish is “as machined” finish. It has a surface roughness of Ra 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.
