In Toral We are experts in the machining of parts for industrial projects and serial production. In our facilities it is possible to shape metal parts through different processes, including pressingIn this sense, the machines used are the hydraulic and mechanical press, two teams that, although they have the same purpose, work in different ways.

Hydraulic and mechanical press: Features and advantages

The industrial presses They are essential machine tools in many sectors, from metallurgy to the manufacture of car components. Two of the most commonly used types are hydraulic press and mechanical pressAs we have already mentioned, both machines have the same purpose: to apply force to shape, assemble or cut materials; however, they have significant differences that can influence the choice of one or the other.

What is hydraulic press?

The hydraulic press works through a pressurized fluid system. This machine uses hydraulic oil to produce a constant force along the entire stroke of the piston. The operating principle of the hydraulic press is based on the Pascal's law, which determines that the pressure applied to a fluid is transmitted uniformly in all directions.

These are the advantages to use the hydraulic press:

• Constant and uniform force, which allows precise control of the applied pressure.
• Ability to handle large loadsThese hydraulic machines have the ability to handle large loads and are ideal for heavy duty stamping and forging processes.
• Greater versatilityHydraulic presses can be used in different jobs and adapt to the shapes and sizes of the pieces.
• Less mechanical wear, thanks to the absence of direct friction between solid components.
• Security and controlSpeed and pressure can be easily regulated, which reduces the risk of errors when machining parts.

If we make a comparison between the hydraulic and mechanical press, we found that the first is somewhat slower and requires greater energy consumption if used for a long time. Finally, it requires more complex and expensive maintenance because it is necessary to check the hydraulic system.

What is a mechanical press?

The mechanical press It is a machine tool that works through a system of gears, cams and eccentrics that transform the rotary motion of a motor in a linear pressing motion. The drive of the mechanical press is fast and precise, making it ideal for series production processes.

These are the advantages to use the mechanical press:

• High speed operationThis machine is capable of performing more cycles per minute, making it efficient for mass production of parts.
• Lower energy consumption in short cycles. Since it works mechanically, this reduces energy expenditure compared to the hydraulic press in certain processes.
• Greater accuracy in repetitive hitsThis machine is perfect for jobs such as stamping and cutting parts that require great precision.
• When comparing the hydraulic and mechanical press, we find that the latter requires less maintenance than the first.

Within the Disadvantages of this machine, it is found that the force is not constant; this means that the maximum force is reached in a specific point of the cycle and is not maintained throughout the entire stroke. On the other hand, the mechanical press does not adapt as easily to variations in size and shape of the pieces and of course, it supposes a increased mechanical wear due to friction between moving components.

Which press is best to use?

The choice between a hydraulic and mechanical press depends on various factors such as, for example, the application, he type of material of the parts and the outputFor example, to work thick and highly resistant materials, the hydraulic press is the best alternative because its force is constant and adjustableOn the other hand, to produce small parts with repetitive geometry, then the mechanical press can be more efficient due to its speed and precision in repetitive cycles.

When a is necessary controlled and adaptable pressure, as is the case with deep stamping, the hydraulic press is the most suitable. If what is needed is a lower operating cost and simple maintenance, then the mechanical press may be the most cost-effective option.
