ANODIZE

Description

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called «anodizing» because the part to be treated forms the anode electrode of an electrical circuit. It is applied on aluminum alloys.

Type II (sulfuric acid): Also called clear anodizing, Sulfuric Acid is the most common and widely used solution for anodized coating, ranging its thickness from 1.8 μm to 25 μm.

Type III (Hard Anodize): Hard Anodizing is used when an extremely hard, abrasive resistant coating is required (coating thicker than 25 μm). Hard anodized coatings can also be grown to greater thickness, typically .002 inches or more. It is basically a modification of the sulfuric acid process, requiring lower temperatures and higher voltages during processing. As a result, a denser, thicker film is formed.

Hardcoat finishes are typically darker in appearance than standard anodizing depending on the coating, thickness and alloy. A variety of colors are available on thinner coatings. Heavier coatings can be dyed black and some darker shades of color.

 

Benefits

Anodize Type II: Sulfuric Acid anodizing improves wear resistance and corrosion protection to a wide-range of aluminum parts because of the hardness of the finished process plus its excellent corrosion resistant features. Because the nature of the process, it is easily dyed a wide range of colors to achieve special cosmetic effects. * Because the nature of the process, it is easily dyed a wide range of colors to achieve special cosmetic effects. Anodize

BRIGHT DIP

Description

Bright dip is a chemical polishing process that removes oxides and enhances the brightness of base metals while at the same time providing a shiny finish to the original base material color. The finished-part brightness is dependent on the type of base material. In addition, the bright dip process does not leave any type of deposit on the surface of the part that might interfere with later processing steps.

Benefits
  •  Bright dip gives a glossy clear o colored finish on parts or products.
  •  Gives protection against corrosion, fading and scratching..
  •  Cosmetic enhancement with a variety of colors for your finish.
  •  No deposits are left on the surface.
Applications

Bright dip is widely used in the automotive industry, appliances, sporting goods, for light reflectors, and more.

EPOXY POWDER COATING INSULATION

Description

Epoxy powder coating has a high dielectric strength, which is a necessary quality for electrical insulation to protect manufacturing people, service technicians, and customers who work on electrical systems. With the proper application technique, most parts can be uniformly coated to ensure a consistent insulation barrier. The material eliminates insulation cut-through from the high-voltage spikes that are often generated in cable systems. Prototype and short-run requirements, in particular, benefit from this insulating process by reducing the need for costly fixtures typically required to insulate or laminate multiple conductor assemblies. What’s more, the smooth and uniform finish that the epoxy provides is especially suited for protecting motor components, switchgear, cables, and other parts.

Epoxy powder coating is a free-flowing, thermosetting dry powder. Think of this process as a way of «melting» paint over a busbar’s surface to create a durable, protective surface with thickness ranging from 6 to 120 mils or .006 to .120 inches. When the epoxy powder cures, a cross-link occurs increasing molecular weight and insulation capability.

 Applications

Epoxy powder is chemical resistant and one of the oldest powder paints used in the electronics industry. It not only protects against corrosion but carries a high insulation rating of 800 volts per mil (.001 inches) at a minimum of 10 mil (.010 inches). Due to safety consideration it is recommended that a Hipot test is performed rather than rely on film thickness. Tensile strength on raw and plated copper bar is in the range of 7500 PSI. UL rating is 130 Cº. Epoxy powder coating’s high dielectric strength can be varied based on the application process, thickness and component preparation.

COPPER

Description

Copper plating is the process in which a layer of copper is deposited on the item to be plated by using an electric current.

        ZINC

        • Zinc
        • Description

          Zinc plating is a soft, ductile, decorative, marginally solderable, corrosion-resistant finish. Unlike most other commonly plated metals, zinc protects the substrate by sacrificing itself and thus corrodes before the base metal. For corrosion protection, chromates are applied over the zinc. There are acid zinc and alkaline zinc plating, providing customers with an excellent sacrificial protection to steel parts. Acid zinc has high conductivity resulting in a brilliant deposit on the part. While alkaline zinc may not be as bright in appearance, the throwing power of the alkaline process is much better. It is also less brittle and provides a more even thickness. Alkaline zinc is usually the best selection, when the part requires plating in recessed areas or the part will be crimped after plating.

          Benefits

          Zinc Trivalent is environmentally friendly and highly protective and bright.With Zinc Trivalent, deposits are extremely low stressed and gives excellent covering power and uniformity of plate distribution.
