Electroforming

What is Electroforming and where is it used?

The best way to describe electroforming is a metal forming process used to manufacture parts using electrolyte deposition onto a model. In the manufacturing industry this model is known as a mandrel. It is a highly specialized process which sounds fairly simple in theory but not so easy in practice. We will now take a …

shot blasting machine

A Guide to Shot Blasting / Shot Peening

Shot peening (also known as shot blasting) is a surface conditioning process carried out after various manufacturing processes. In simple terms it increases/improves the surface finish. Shot peening is done with the help of small balls which are streamed out in the form of a jet at very high velocity, accelerated and directed toward a …

What is Parkerizing, how does it work?

Parkerizing is a method used on ferrous metals such as wrought iron, cast iron, steel and alloy steel, offering added protection from corrosion. This process is not suitable for non-ferrous metals like a copper, brass, aluminium, and plastic items. It can also be used to improve the wear resistance of materials by adding a surface …

electropolished engine

What is Electropolishing and what is it used for?

Electropolishing is a material removal process using an electrically powered chemical process called electrolysis. In this process the amount of material being removed is very small as it is done for polishing purposes only. A negatively charged copper electrode and positively charged workpiece are dipped into a solution of fast flowing electrolyte solution. When connected …

The melting point of steel alloys

The Melting Point of Steel Alloys

In simple terms, the melting point of steel for example, is the temperature when it starts to change from a solid state to a liquid. At this specific melting point temperature both phases of the substance exist in equilibrium. Therefore, further heating needs to be passed through the substance to complete the transition from solid …

AISI 316 Stainless Steel: Specification and Datasheet

The SAE / ANSI / AISI 316 is the second most commonly available/widely used type of stainless steel after the SAE/ANSI/AISI 304. Considered the generic workhorse, the SS 304 can serve in most situations with great success. However, while both are typically used in industry, the SS AISI 316 is used in even harsher environments …

Anodizing aluminium – process description & design guide

Anodizing is an electrolytic surface treatment most commonly used with aluminium components. It creates a hard, durable, corrosion-resistant, non-conductive, and often reflective oxide finish on the outside surface of the anodized part. It also makes the surface of the component easy to dye and paint due to the porous nature of the oxide layer. For …
