Why You Should Rely on a Blacking Process

Blacking offers manufacturers a way to manufacture steel and iron components so they are more attractive for sale. This type of process is not only easy to apply but safe as well. The chemical immersion process, which is facilitated at room temperature, does nothing to change a component’s dimensions. As a result, this type of protocol is often used for precision-engineered parts. Therefore, blacking is typically used in the machinery and tool manufacturing fields.

The Benefits of Blacking

So, when you use blacking, you will realise a number of benefits, namely in the way of the following:

  • Corrosion resistance – Blacking a surface causes the surface to absorb oil, wax, or a sealant, thereby providing corrosion safeguards.
  • No dimensional alterations – Blacking machined parts offers a tight tolerance, which means that painting or metal plating are not necessary.
  • Additional sales – When a resilient black finish is applied, it adds to the value and appeal of the part or
  • Safety and enhanced production – Blacking reduces the glare of illumination. As a result, moving parts that are black are also safer. This type of product also lowers worker fatigue.

Enhanced Sales Appeal

So, a process such as Blackfast metal blacking is not done for aesthetic purposes only. The sales of components that have undergone a blacking process are also based on the safety of the parts and their overall usage. When you do not have to worry about dimensional alterations or corrosion, it also makes it easier for you to sell a better quality part.

Defining the Process

By definition, blacking, which is also known as blackening, is a finishing process that changes the composition of certain metals. This process produces a stronger protective barrier on a metal’s surface – a barrier that keeps a part safe from moisture problems or corrosion. This type of process is also more economical. Therefore, it is a preferred method used in various industries today.

The Basic Steps

The blacking process used on metals makes use of a simple dipping operation that leads to uniform colouring. The colour that is applied is used for machined surfaces, blind holes, and threads. The blackening results in a chemical conversion on the surface of the part. In turn, degreasing is employed, as well as the immersion of the part in a surface conditioner. Afterwards, the blacking is applied. The corrosion protection is provided by a final immersion in dewatering oil.

Extending the Lives of Parts and Components

So, you have good reason to consider a metal blackening kit for future manufacturing projects. The reason why most manufacturers choose to use this type of process is because it provides corrosion resistance. In addition, blacking makes a part stronger and more resistant to the elements. Therefore, manufacturers who use this type of treatment also produce components with a longer life.

This type of process, as indicated, is more cost-efficient than the use of metal plating. Blacking normally increases the dimensions of a metal surface by about one micron. For most parts, this added size is negligible. Therefore, the part can still be used for its intended purpose.

Two blackening processes are used for metals: cold and hot blacking. Either process affords certain advantages. Which one you choose will be contingent on the specific application and your manufacturing setup.
