Back in the days, people who wanted to cut, stamp or shape metal would cut it and polish it to shape using their own hands and some basic tools. Whilst this is still an alternative today, it is an impractical method for pieces that require precise dimensions and for those in need of mass production.
When it comes to metal pressings, there are two primary methods to choose from: stamping and fine blanking. Each of these processes has different benefits, price, size and material.
Stamping metal pressings involve hydraulically or mechanically driven presses. Over a certain period, these can reach higher phases and are more typical in industrial press shops. Whilst hydraulic driven presses can provide packed force anywhere you want, mechanical driven presses can only transmit complete force at the bottommost of the stroke.
On the other hand, fine blanking metal pressings generally cater to limited materials. If you choose this process, you can only use stainless steel, carbon, alloy, copper, brass and aluminium. This will still offer you an extensive work to operate with. Those who will be using a different metal would have to choose a different process.
A common fine blanking press will comprise of a guide plate, which has the same size and shape to blanking die; female, which is a hardened blanking die; and male, which is a hardened die punch. Instead of common punching, many people argue that this process seems more like an extrusion.
Other than determining the material you need to use, you will also have to identify the number of metal pressings you will need. Whilst the two metal pressings processes mentioned here provide similar results, it is ideal to choose what will best suit your needs.
