If you are using any metal tool or object in your daily life, it is more than likely that it has been metal that has been pressed. Things made from metal are often formed to the final shape by an intricated and sophisticated technique know as metal pressing.
The art of metal pressing has been around for centuries, ever since man discovered metal was a hard substance that could be converted through heat or pressure to form the required shapes or configurations. Pressed metal requires a die that is much harder than the metal being pressed and a press that can apply the required force to enable the metal to acquire the required shape of the die. Hard steel alloys are used for dies, while the pressure is applied mechanically or hydraulically. The die requires having a reverse image of the metal part that is desired. It is also important that the correct size of a metal sheet or plate be inserted as any metal pressing NZ will have a greater surface area than the projected area that it covers. It is important to reduce wastage and any offcuts left over after the metal is pressed so that the required economy is ensured.
This complicated process is helped by the use of computer controlled equipment and this helps to reduce errors while ensuring metal pressing NZ of the correct shape. Pressing can be shallow or deep. Shallow pressing is more of use for thicker and harder material, while a deep press will be more effective for thin metal sheets. In some cases, the press also has arrangments that allow for the heating of the metal in order to make it pliable and thus easier to bend.
Metal pressing NZ is used by many industries in New Zealand to make items of daily use and in the manufacture of vehicles, and instruments. It is almost impossible to manufacture any modern appliance or machinery without having to use metal pressings for its various parts and even its exteriors. Most industries in New Zealand use computers that allow them to completely automate the pressing process and to achieve the desired economy and efficiency while carrying out this work. In metal pressing NZ, metal is manipulated into a new shape and this work is carried out by heating or by the application of mechanical force. Some metal presses will combine these two methods to get the required shape. Heat can cause additional stresses in the metal and also cause a change in dimensions. These factors have to be considered in any design to ensure that the final product has the dimensions in all axes, as required.
The shaping and forming of metal are very necessary for many industries in New Zealand and requires proper presses, dies and other machinery for carrying out the work as desired. It is a complex process that requires a high degree of sophistication and careful designing of dies, presses, and cutting of metal to achieve the required quality and economy.
