This means you can choose a press with a tonnage really adapted to your needs, without having to oversize it to benefit from sufficient force at the beginning of the operation. However, hydraulic presses allow the full power of the press to be used throughout the manufacturing process. Repeatability is lower with a hydraulic press than with a mechanical press. They generally make less noise than mechanical presses of equivalent tonnage. Hydraulic presses offer great flexibility thanks to their length of stroke as well as their variable and customizable pressure. They are particularly suitable for deep drawing but can also be used in other applications. These machines generally offer lower production speeds than mechanical presses, and are more suitable for small-volume production. They require a lot of maintenance, but with a well-maintained hydraulic press, breakdowns are rare and relatively easy to repair. They generally have a smaller footprint than mechanical presses of equivalent tonnage. Hydraulic presses can compress all types of materials. In the latter case, you can consider transfer presses that allow you to carry out consecutive striking in a fully automatic manner.Īll these criteria will allow you to choose the most suitable technology for your installation, whether it be hydraulic, mechanical or pneumatic. For mass production, it is essential to know whether you need single striking or a repeated striking. For one-off needs or small series, you might be interested in manual, mechanical or hydraulic presses, or even electric presses which also exist in portable models. Production requirements are also important to consider, whether they are unitary or small or large series. There are presses from 5 kN (0.51 metric tons) up to 500,000 kN (50,000 metric tons). The tonnage of the machine is usually expressed in kilonewtons (kN). This will depend on the type of material you will be working with, its thickness and the type of stamping to be performed (for example, the stamping depth or the cutting perimeter). You will then need to define the tonnage of the machine you require. You will also need to have a fairly accurate idea of the finished dimensions of the workpiece to be formed, and the dimensions of the parts to be handled for punching or riveting, in particular to be able to correctly choose the dimensions of the worktable and the press opening height.
