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.

Copper Plating and the Use of Copper Balls

copper-plating-process-nitec-ukCopper balls have been specially designed to aid the quality of electroplating.  The balls are 25mm, 31mm, 40mm or 50mm in diameter and are made up of 99.9% copper and between 0.04 and 0.06% phosphorus.  They enable the quality of copper plating to be heightened.  This is due to them being able to give free flowing material which dramatically reduces the development of sludge during the process of plating.  This is their sole purpose.  It is also useful that they are able to reduce sludge development because this extends the anode baskets life because the sludge does not erode them.

Successful Copper Plating

The anodes are created using the purest of copper which is oxygen free.  The anodes must be made out of oxygen free copper so that the correct phosphorus content occurs for the electroplating process to be successful.  This process is watched and monitored strictly for quality control and this highly automated process creates a product of great uniformity and high quality of plating.

Why Choose Copper Plating?

Copper plating is functional and decorative.  It is well known for being an excellent conductor.  The deposited layer which is left when copper plating occurs is very bright and levels well.  Copper plating is often used in Medical settings or laboratories due to it being able to kill off bacteria naturally without need for any chemical assistance.  In reference to its decorative flare – this is due to its highly polished copper-pink appearance.  Lacquers can be applied so as to prevent tarnish from building up on the copper plating if it is solely intended for decorative use.

Is Copper Plating the New Solar Panel Platform?

taiwan-copper-plating-nitecIt seems that the Industrial Technology Research Institute of Taiwan (ITRI) have discovered that Copper plating could be the solar panel platform.  They intend to cooperate with aiding the development of copper plated solar panels on a small-scale, fast production.  The collaboration between Motech Industries, Gintech Energy Corporation and TSEC Corporation and that of the ITRI seems to have captured gaps in the photovoltaic (PV) global market.

Copper Plating and Taiwan

The General Director of ITRI’s Green Energy and Environment Research Laboratories, Dr. Robert Yie-Zu Hu, stated that this brand new development has in fact been in research state since 2012 and that the copper plating for silicon solar cells metallization technology currently achieves 20% energy conversion.  This is a first for copper plated solar cells in Taiwan, where production can reach 200 solar cells per hour.  The efficiency of the solar cell will increase by 0.2% with the cost reducing by 5-7%.

Increased Rating of Copper Plating

Many foreign manufacturers have been developing copper plating technology themselves but no one has so far been able to produce copper plated solar panels on such a large scale.  This could, therefore, be a large profit making scheme for Taiwan, also making them leaders in the global copper plated solar cell market.  Currently, they are the world’s second largest solar cell market, but with the industry now stable and demand rising, this could easily change.  So, will we be seeing these copper plated solar panels in Britain any time soon?

Why Choose Copper Plating?

Copper plating is functional and it looks good.  Copper plating is very bright and eye catching.  It naturally kills bacteria and is often used for decorative purposes.  Copper plating has a smart, polished copper-pink finish and can be lacquered to prevent tarnish from occurring.  But the best reason for it being used as a solar panel is due to it being such an excellent conductor.

Why Choose Electroplating?

copper-electroplating-nitecElectroplating is a modern form of metal finishing.  It is commonly used in the automotive, aerospace, medical, army and electrical industries.  It occurs by means of an electrochemical process when metal ions in an electrolyte solution bond to a metal substrate through electrodeposition.   The required metal component is suspended in solution, whereby a direct power supply provides a direct flow of current to the said metal component in the chemical bath.  This current provokes the ions in the solution to attract to the surface of the metallic part, resulting in a metal coating which covers the base metal thoroughly.

Electroplating Benefits

Electroplating is mainly done in order to enhance the performance and longevity of the component part in question.  Certain characteristics can be added to the part in order to create specific needs for the manufacturers.  These can include areas such as:

  • Lower friction through greater lubrication
  • Better wear, abrasion and corrosion resistance
  • Temperature and impact resistance
  • Improved conductivity
  • Improved solderability
  • Porosity reducing
  • Creating added strength and hardness to the component
  • Creating a thicker appearance to smaller or undersized components
  • Increased protection for EMI and RFI shielding

Common Plating

Plating facilities match base metals with a wide array of coating surface metal finishes.  The most commonly used in this field are copper, brass, nickel, steel and bronze.  In order to decide which surface metal is used to coat for the finish, the components uses are highly considered so that the manufacturer can get the highest performance and longest lasting component part electroplated.

As examples:

Gold plating is the perfect solution for electrical conductivity, heat protection and corrosion and can survive in a multitude of environments and temperatures.

Silver plating is commonly used in the electrical industry dues to its low electrical resistance.

Nickel plating is ideal for the chemical industry.  It protects against chemicals and is corrosion and wear resistant.

Copper plating is most commonly used in the automotive industry.
