Metal stamping is a process used in many different industries for countless everyday uses, many that we aren’t even aware of.
Such uses include parts in the auto industry; simple components such as washers, hallmarks, bike parts and many parts of other household and everyday appliances.
To put it into basics, the metal stamping process is a process which can transform sheets of metal into various shapes; not only can this process be valuable for parts and components of a flat nature, but also for other uses such as moulding metal for tools, pans and cutlery, etc.
Metal stamping is useful for numerous many other components, some of which are listed below:
Locks and Keys
Building Construction Industry
Individual Components within Furniture
Components within Household Appliances, such as Fridges, Blenders, Washing-Machines, Kettles, Dishwashers, Microwaves and so much more. From Large household appliances all the way down to everyday utensils
Construction Industry (inclusive of aerospace, automotive and marine)
… And much, much more.
There are many ways of pressing metal, such as die, punching, casting, moulding, cutting, blanking, embossing, bending, shaping and coining.
Yes, this process is also used to create monetary coins; literally. Have you ever wondered how coins are actually made? How they weigh the same, look the same and feel the same – right down to the tiniest detail?
The whole process of coining is created via the metal stamping process. This is both time and cost-efficient while being an effective way of producing large volumes from sheet metal. This method is also used for medals, hallmarking and such like.
However, many centuries ago, an entirely different method was used for coining, and in this day and age, there are many stages of operation that follow a particular coining process.
– Master Design Stage
3D models of the actual design used to be made by moulding and refining plaster. In this day and age, this can be done using a digital model.
-Metal Casting Stage
The raw metal is then melted into sheets or strips. This is then rolled to the required thickness and moulded.
The blank coins, known as discs are punched and edged (if required) at an incredibly fast rate within the blanking process.
The blanks are heated in preparation for the next stage and then minted with the design; this is done by way of pressing; also known as die-casting.
The coins are now cooled and completed, ready for the quality control checking.
There are many other stages in between these main steps, but this is a basic overview to the beginner. Maybe it’s not as simple as you thought, or perhaps it might seem a lot more complicated than you had imagined? Either way, there are many experts in this field with the relevant industry experience, and both tools and knowledge in order to construct such everyday items which we take for granted and don’t usually give a second thought to.
