Shotblasting – The Abrasive Protection

shot-blasting-nitec-ukShotblasting is a technological process which enables impurities of metal parts to be removed from a wide variety of surfaces, through the medium of abrasionShotblasting can be used as a preparation method performed before other processes, such as welding, colouring, painting, where imperfections must be eradicated to gain a perfect finish, join or seal.  It can also be used as a method of surface protection.  The end result of a cleaned metal surface depends on multiple characteristics.  These can be examples, such as the mass size of the abrasive particle, its shape, density, coverage of strokes (kg/m²), the particle impactor angle and the particle velocity.

The shotblasting process can be undertaken for multiple reasons – the cleaning, strengthening or polishing of metal.  These processes are used in almost every single industry which uses metal, including that of the aerospace, automotive, construction and transportation.  In order for shotblasting to take place, two technological processes can be undertaken – wheelblasting or airblasting.

Wheelblasting for the Shotblasting Process

Wheelblasting is the direct conversion of electric motor energy into kinetic abrasive energy through the use of a rotating turbine wheel.  Each wheel has a capacity starting from 60kg per minute and maximising at 1200kg per minute.  Companies need wheelblast machines where large parts or great areas have been derusted, descaled, deburred, desanded or if they need cleaning in some way.  Often the way to work out how to choose which process your business needs is based upon the size of the metal part that needs work doing to it – the ease of its transportation is the deciding factor.

Shotblasting and the Airblasting Process

Airblast machines are pneumatically accelerated machines which are air powered, with projected nozzles angled on to the component – the process, quite literally, is all in the name!  Airblasting can occur in two ways, either in a blastroom or a blastcabinet.  If special applications are needed, water mix can be used which is known as wet blasting.  Whether you need airblasting or wet blasting, the blast nozzles can be installed in to unique positions to target problem areas.  They can be operated manually or automatically or even by robots.

Shotblasting at NiTEC UK

Shotblasting at NiTEC can occur for component parts which weigh up to 20 tonnes.  Usually, the shotblasting process is required prior to our electroless nickel plating process, as a surface preparation, in order for you to gain the best finish and your metal components to get the best protection.  The better the abrasive finish from the shotblasting process, the better the electroless nickel plating, the better your component part will work and the longer it will last for you.  Shotblasting is an important process.

Everything You Need to Know About Vapour Blasting

aqua blastingAqua blasting, or vapour blasting as it is sometimes called, is commonly used for fine surface preparation, de-burring, finishing and polishing.

The aqua blasting service here at NiTEC UK will degrease, blast and finish components all at the same time, providing a complete vapour blasting service for a variety of components. Other uses for the process include the removal of carbon deposits, the removal of paint, rust, and similar deposits in the engineering industry, and surface preparation prior to bonding, re-painting or re-coating.

How Does Vapour Blasting Work?

The process of vapour blasting is completely dust free, and uses a mixture of a media and water to form a slurry. This slurry is then pumped through a vapour blasting nozzle under considerable pressure whilst at the time being mixed with a high pressure air supply. The pressurised slurry then flows over and around the part, component or surface that is being blasted, producing a clean, smooth finish.

What are the Advantages of Aqua Blasting?

Vapour blasting has a lot of advantages over conventional sandblasting or bead blasting. Unlike shot blasting (and other blasting methods which actually move the surface material from the components), the process is non-intrusive; and it is perfect for delicate parts and soft metal. Aqua blasting is commonly used when a fine finish is required for aluminium, alloys, steel and many other metals; including bronze, magnesium, titanium, brass and copper.

With the water acting as a protective buffer; and the emulsion gently eradicating any grime – the underlying surface is crucially left intact. Vitally, there will be no alteration of critical dimensions. The creation of any dust is also avoided; as there no break-up of any media during the aqua blasting process.

Key Advantages of Aqua Blasting:

  • Can be applied to almost all metals
  • Surfaces are degreased and cleaned in tandem
  • Cleaning process relies on water flow and not impact
  • Makes surfaces more stain resistant
  • Singular part or batch process
  • No dust from the process
