At Rye Metal Finishing, we provide the following services –
This is the operation of forcibly propelling a stream of abrasive material (media) under high pressure to smooth a rough surface, roughen a smooth surface, or remove surface contaminants. Pressurized air is used to propel the media at the surface being treated. This is our preferred method of surface preparation for powder coating as it provides an excellent key for maximum adhesion of the powder.
At RMF we have two shotblast rooms, one dedicated to ferrous materials and the other dedicated to non-ferrous materials. For our non-ferrous room, our chosen blast media is aluminum oxide. This also gives us the facility to change this to glass bead, as it allows us to blast stainless steel, without the possibility of corrosion from trapped ferrous media.
Our non-ferrous blast room size is 6m long, 4m wide and 2.3m high which allows us to accommodate larger items.
Our ferrous blast room is 6m long, 5m wide and 3.5m high.
Glass Bead cleaning
Or Bead blasting, is the process of removing surface deposits by applying fine glass beads at high pressure without damaging the surface. This process is less aggressive than Shot Blasting and can be used to clean and prepare stainless steel and softer aluminium components. We can perform this in our non-ferrous blast room or in our dedicated bead blasting cabinet.
Metal/Thermal (Arc) Spraying
Metal/Thermal spraying is widely used to provide corrosion protection to ferrous metals or to change the surface properties of the sprayed items, such as improve the wear resistance or thermal conductivity. All methods of thermal spraying involve the projection of small molten or softened particles onto a prepared surface where they adhere and form a continuous coating. To create the molten particles, a heat source, a spray material and an atomisation/projection method are required. Upon contact, the particles flatten onto the surface, freeze and mechanically bond, firstly onto the roughened substrate and then onto each other as the coating thickness is increased. We can also use this process to build up pitted or holed car/motorcycle etc panels and to coat or non metal substrates, MDF or polystyrene for example. We are able to coat in Zinc, Aluminium, bronze or copper.
This is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher and more durable than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions and automotive and bicycle components.
Our state of the art spray booth and fan oven can deal with components as small as a single bolt, up to items 4m in length. Our oven size is 4.2m long, 2.5m wide by 2.1m high.
Alloy wheel refurbishment
We offer a full alloy wheel refurbishment package. The wheel is chemically dipped to remove all existing powder coating or paint (this DOES NOT affect the wheel in any way). The wheel is then shotblasted back to the parent material and inspected for any cracks or defects. WE DO NOT REPAIR OR RE-COAT ANY WHEELS THAT ARE FOUND TO BE DEFECTIVE. Light scuff damage from “kerbing” or deeper corrosion pitting is repaired using a specialized filler, purpose made for powder coating. The wheel is then “out gassed” in our fan oven before being coated in a zinc rich primer coat. This is followed by the first of the colour coats and finally a clear protective lacquer. As the whole wheel is re-furbished and not just the face, it produces a much superior finish to just spraying the face with an aerosol or wet spray (as many “specialist” mobile services offer). The finished product is a wheel that has a durable finish and looks as good as new.
PLEASE NOTE: The tyre must be removed prior to us commencing any work on the wheel. We can do this on site as well as refitting and balancing the wheels for small additional cost, contact us for pricing.
