Powder Coating

At KMA Shot Blasting Limited we offer all powder coating services. Powder coating is essentially a coating type applied in the form of free flowing powder particularly on metal surfaces. Powder coating is a substitute for paints without the usual solvent and filler parts. Powder coating is an electrostatic process where heat is applied for the free flow of powder through powder spray guns. This thermoplastic powder then forms a thin skin and gets applied on a surface.

Alloy Wheels Powder Coating

Metal powder coating was first introduced in United States in the 1950’s and is now used in almost 15 percent of all surfacing jobs. Apart from automobile bodies, powder coating is extensively used in sports goods, and manufacturing industries. At KMA Shot Blasting Limited we do motorbike powder coating, bicycle powder coating, and alloy wheels powder coating, Powder coating of metallic frames is also an important area of operation at our works this list is not exhaustive.

Process of Powder Coating

For getting the best motorbike powder coating, four-wheeler powder coating or bicycle powder coating work in Poole and Bournemouth, you could always rely on KMA Shot Blasting Limited. The process of metal powder coating followed at KMA Shot Blasting Limited is highly methodical and completed in three interlinked stages:

1. Pre-treatment or Part preparation

2. Application

3. Curing

All metal surfaces go through these three steps before it is thoroughly powder coated. Finally it is quality checked, wrapped for protection and delivery of the product.

Pre-treatment

This process involves removal of grease, oil, soil, welding scales, and metallic oxides that might be present on a metallic surface. Both mechanical and chemical processes are used for pre-treatment of metallic bodies. Mechanical processes include shot blasting, sand blasting and abrasive blasting. Chemical methods of pre-treatment include hand preparation. Pre- treatment not only cleans the metallic surface to be powder coated, but enhances bonding between powder and metal surface.

Application

Use of electrostatic gun for spraying powder is the usual process of powder coating used at KMA Shot Blasting Limited. The powder inside a spray gun develops a positive charge while the metallic surface to be powdered remains grounded. Compressed air sprayed at high speed helps formation of electrostatic charge between the powder particles and metal surface. The nozzle used for spraying depends on the shape of the surface to be powder coated. Thin substrates are coated and then stoved for 12 minutes. However, with thicker materials it is heated for longer periods prior to coating allowing the powder particles to melt and form a uniform thin film. On cooling this film becomes hard and durable.

Curing

Curing is a process wherein epoxy or polyester powder is exposed to melting temperature allowing it to flow and chemically react to form a polymer of higher weight. This curing process can be carried out at a specific temperature, the time span is dependent on the heat required to warm the substrate.

Powder Coating and its Advantages

Powder coating done at KMA Shot Blasting Limited offers a durable coating to metallic surfaces and hence used in motorbike powder coating, bicycle powder coating, and powder coating all types of metal substrates. Powder coated surfaces are more resistant to chemicals, moisture, impact and even ultra violet rays when using architectural grade powders as compared to liquid paint. Corrosion, scratches, and chipping may be also prevented to a greater extent. The finish of any surface that is powder coated is of uniform appearance when viewed from any angle. This may not the case with liquid spray painting.
