Metal Coatings

Aside from being powder coating specialists, ChinaSavvy specializes in a number of metal coatings, making us a world class metal finishing shop that offers a full spectrum of services to meet your every need.

The use of coatings on metal components and tools is not only increasingly popular, but has become an essential in order for base materials to perform tasks beyond its capabilities.

Metal coatings are used in order to change the surface properties of the substrate to that of the coating being applied. While the substrate is responsible for load bearing capabilities, the metal coating provides a durable and corrosion resistant layer.

As a superior metal finishing company, ChinaSavvy knows both the functions and importance of metal coatings and offers:

  1. Corrosion Resistant Coatings
  2. Decorative Coatings
  3. Powder Coatings

 

Corrosion Resistant Coatings

Aimed at protecting substrates against the gradual chemical or electrochemical attacks from the environment in which it is placed, corrosion resistant coatings can aid in protecting substrates against various types of corrosion, including general, localized, galvanic, caustic agent corrosion as well as stress-corrosion cracking.

Here, the type of coating applied will depend on the type of metal (of which the substrate is made) as well as the type of corrosion prevention needed.

Chromium, copper, nickel and zinc are widely used corrosion resistant metals and are applied in order to control corrosion. Process and technology developments has allowed manufacturers with an assortment of of solutions that offer protection against corrosion.

ChinaSavvy offers a number of corrosion resistant metal coating solutions, including:

 

Decorative Coatings

Offering a range of decorative metal coatings, ChinaSavvy specializes in a number of decorative coating processes including Physical Vapor Deposition (PFD) and decorative plating.

Physical Vapor Deposition (PVD) is a plasma coating deposition process and entails the deposition of a thin film on the surface of the substrate using a vaporized form of the desired coating material.

An environmentally friendly decorative coating process, PVD coatings offer resistance to wear, a superior hardness as well as a coating that will not tarnish, chip, fade or corrode.

Using a number of deposition methods ( including Sputter Deposition, Evaporative Deposition, Cathodic Arc Deposition, Pulsed Laser Deposition and Electron Beam Physical Vapor Deposition), ChinaSavvy works with various PVD coating metals such as Chromium, titanium and zirconium.

Plating processes are also used in order to create a decorative metal coating. Electroplating entails the use of an electrical current in order to coat an electorally conductive substrate with a thin layer of metal, while electroless plating uses an autocatalytic reaction in order to deposit a thin layer onto the substrate.

Able to be applied to a number of ferrous and non-ferrous metals, ChinaSavvy offers:

  • Chrome Plating
  • Copper Plating
  • Gold Plating
  • Nickel Plating
  • Rhodium Plating
  • Silver Plating

 

Powder Coatings

An extremely popular metal coating, powder coating is applied as a free-flowing, dry powder which is typically thermostatically applied and followed by curing.

As powder coating specialist, our powder coating shop uses:

  1. An Electrostatic Gun (Corona Gun)
    1. Most commonly used, this electrostatic gun imparts a positive electric charge to the powder, which is then sprayed towards the grounded part to be coated either through mechanical or compressed air. The positive electric charge causes the powder to accelerate to wards the part to coated.
  2. The Tribo Gun
    1. Also used in our powder coating shop, the Tribo Gun positively charges the powder by rubbing it in a Teflon tube inside the barrel of the gun. The powder, now positively charged through friction, is sprayed towards the grounded part.
  3. Fluidized Bed Method
    1. Here, the part to be coated is heated and then dipped into an aerated, powder filled bed. The powder now sticks to the part and melts, followed by curing to create a powder coating. Note that this process is more commonly used in cases where a coating thickness of more than 300 micrometers is required.

 

Powder coating also offers a number of benefits, some of which includes a longer life (than that of paint coatings), a uniform film thickness and a resistance to corrosion. Offering a number of color and texture options, powder coating is also an environmentally friendly metal coating process and parts coated using powder can be ‘bent’ without cracking.

Metal coatings are not only used in order to create a decorative finish, but also applied to substrates in order to provide a resistance to corrosion as well as a resistance to abrasion. Metal coatings aid in minimizing friction as well as aid in the protection of substrates against oxidation, rust, corrosion and chemicals

ChinaSavvy, being a superior metal finishing company abased near the heart of industrial China, offers a full spectrum of metal coating services, each designed to meet specific requirements. Powder coating specialists, we are also masters in the field of decorative and corrosion resistant coatings, and work with a large number of materials to meet your requirements.

Operating to ISO 9001:2008 standards, you can be sure that only the best metal coated product leaves our shop and reaches you.
