Everything you need to know about Shot Blasting

shot-blasting-electroless-nickel-plating-nitecShot blasting is a key factor in the fabrication process.  It is essential so that a clean finish can be provided in order for welding to be undertaken.  It also enables a keyed surface to be produced so that paint can be accepted by the prepared façade.

The Process of Shot Blasting

Shot blasting is undertaken by shot being fired or ‘blasted’ directly at steel, yes, the process is all in the name.  The force of the shot being blasted at the surface of the steel displaces dirt and scale, therefore cleaning the steel and preparing it for the welding process.  This is due to the indentations caused by the shot repeatedly hitting the steel surface, creating a rough texture, which is approximately 70 microns deeps.  Due to this abrasion, it enables paint to stick properly and long term to the steel surface, which creates protection and aids longevity to a component part.

Shot Blasting and Electroless Nickel Plating

The shot blasting preparation is often performed prior to the electroless nickel plating process, but for this to happen the surface preparation must be high quality and thorough, which is why shot blasting is used.  To achieve the ultimate final surface finish, chemical cleaning and activation processes, such as aluminium oxide 180-220 grit are used.  By choosing NiTEC UK to undertake your shot blasting and electroless nickel plating solutions, you know that the standards met will be the highest every time.  At NiTEC UK, the stainless steel shot blasting booth has the capacity to take 216m³.  This minimises the particles which settle on the component parts during their shot blasting or heat treatment processes.

Top 3 Reasons to Use Aqua Blasting as Your Metal Cleaning Method of Choice

Aqua BlastingAs experts in metal finishing and metal plating, NiTEC UK have recently expanded our services to include aqua blasting, or vapour blasting, as it is sometimes called. This wet blasting process has many great advantages, including the ability to effectively and gently eradicate surface dirt and grime from metal components. Here are 3 reasons to choose aqua blasting as your metal cleaning method of choice.

Aqua Blasting Leaves the Underlying Surface Smooth

The process permits non-aggressive surface cleaning in order to produce a satin finish on a wide range of metals. Aqua blasting cleans by the flow of water and not impact, and the water acts a lubricant between the media and the component. It involves the use of a non-ferrous media; which is subsequently mixed with water to result in an extra-smooth finish once the process has been carried out. That is possible thanks to the flow of a water-borne abrasive.

Unlike shot blasting, and other blasting methods which actually move the surface material from the components, the process of aqua blasting is non-intrusive. It is, therefore, suitable 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.

Critical Dimensions of the Part are Not Affected

Another benefit to aqua blasting is that the water used in the process acts like a protective buffer. This means that the emulsion is able to effectively lift off any grime, all the while leaving the underlying surface intact. That means that there will be no alteration to the dimensions of the treated part, eradicating the need for post treatment plating etc.

Aqua Blasting is Useful for a Variety of Needs

In addition to its gentle cleaning properties, aqua blasting is a process that can also be used for the removal of carbon deposits, and the removal of paint, rust, carbon, and similar deposits in engineering industries. It can also be used as a method of surface preparation prior to bonding, re-painting or re-coating.

Pickling Stainless Steel for World Renowned Aerospace group Meggitt

As experts in the various processes of metal finishing, and often the company of choice for several aerospace companies, NiTEC recently took on a project pickling steel for world renowned Aerospace group Meggitt.

Meggitt PLC – Engineering for Extreme Environments

Meggitt PLC is a global engineering group specialising in extreme environment components and sub-systems for aerospace, defence and energy markets.They are a FTSE 100 supplier of aircraft parts, and they supply flight displays and wheels to both Boeing and Airbus.

Why Pickle Stainless Steel?

The process of pickling stainless steel is a metal surface treatment that is used to remove any impurities from the surface of the metal. This could be stains, inorganic contaminants, and rust or scale. Acid is commonly used to remove these surface impurities.

The Safe Handling of Hydrofluoric Acid

pickling stainless steelStaff at NiTEC used hydrofluoric and nitric acid to remove the discoloured scale from the stainless steel, and as you can see from the pictures, the process makes a huge difference to the surface of the steel.

Hydrofluoric acid is a really effective acid for pickling; although it is typically more expensive than other acids, the process of pickling is much quicker and it effectively minimises the base metal loss.

We had the exciting task of pickling stainless steel for a project located in offshore Brazil and were lucky enough to be chosen as partners in the project because of our expertise in the safe handling of hydofluoric acid, which is an integral part in the process we carried out for Meggitt.
