TOP 10 HYDRAULIC PRESS APPLICATIONS - CULTURE VOCABULARY - 2025

Some applications of the hydraulic press are forging, glass thinning, making cosmetic powders and forming pills in the medical industry. A hydraulic press is a device that uses a hydraulic cylinder to generate a compressive force. This instrument has multiple uses. In addition to those mentioned above, one of the main ones is to transform different types of metal objects into metal sheets.

A hydraulic press can compress a material to its full extent and requires less space than a mechanical press. Hydraulic presses can be automatic or manual, depending on the industry where they are used.

There are many types of hydraulic presses. The gazebo press is a manually operated press for lighter duties such as stamping, punching or flattening metal. The laminate press uses heat to laminate certificates, identification documents, or even book covers.

There are also C-shaped presses that have specific applications for drawing, straightening, and assembling work. On the other hand, the pneumatic press uses less force and is common for uses in automobile or aircraft brake systems. These industrial presses need an operator to assemble, draw and punch.

The inventor of the hydraulic press was Joseph Bramah, which is why it is also known as the Bramah press.

10 applications of the hydraulic press

1- Multipress

The hydraulic multi-press can be used for literally thousands of applications. From stamping equipment, to assemble one part to another or the construction of various items such as filters and compact powders.

It is also used to trim excess metal parts as in the case of a gearbox or to produce controlled portions of fish, chicken or other foods.

2- Compression presses

Hydraulic compression presses are used as the core of any automotive crushing system. In this process, a hydraulic motor applies great pressure to the fluids within the cylinders.

This fluid pressure causes the plates to lift and then with great force, the plate is pushed over the car, crushing it.

3- Pneumatic presses

These presses are the most basic that are used in the industries, because in this system the air is compressed to create a pressure that produces movement. The advantage of mechanical presses is that operations are performed more quickly.

Its disadvantage on the other hand is that it is not capable of creating too high pressures, as other hydraulic presses do. They are typically used in automobile and aircraft brake systems.

Industrial uses for pneumatic presses include assembling, drawing, drilling, among others. To function they need an operator who must handle additional safety accessories such as electrical safety systems.

4- Cosmetic industry

Hydraulic presses can be used to press cosmetic materials into makeup such as eyeshadows, cosmetic blush powders, and others. Pneumatic presses are the most appropriate for this type of work, since they produce very fine powders of excellent quality.

5- Medical field

Hydraulic presses are also used in the medical field for the formation of tablets and tablets. These presses can compact granulated or powdered ingredients and tablet them for the pharmaceutical industry, chemical plants, hospitals, research institutions and laboratories.

They are lightweight, small in size, and packed with various functions. An average press can form more than 5000 tablets per hour.

6- Creation of credit cards

With a vacuum press used to make foils, credit cards can be made, which are formed from several superimposed layers of plastic. A film can also be applied to the plastic layers.

7- Creation of swords

The presses are used to make swords, since they allow to give a flat shape to the raw steel and achieve the hardness but at the same time the lightness that these types of weapons need, which are currently used more for exhibition and collection.

8- To prepare powdered chocolate

When cocoa beans are processed, a liquid known as cocoa liquor is produced. If you want to keep only the cocoa, without adding sugar, preservatives or fats, the liquid is squeezed in a hydraulic press.

After this stage, it is processed again to form cocoa powder, in the way we know it and without added fat.

9- Forging industry

Large ton hydraulic presses are used for forging and cutting metals on a large scale.

Currently, most of the forging processes are carried out with hydraulic presses, which allow an adequate distribution of pressure in the material, which reduces the number of elements used and improves production by increasing the speed in manufacturing.

10- Creation of ceramics

Hydraulic presses can be used to manufacture glass products, metal connectors, Teflon materials, magnetic elements, and clay products that require a considerable amount of force to be applied to form a target from powdered or granulated substances.

Hydraulic press working principles

The hydraulic press relies on Pascal's Principle to function, which indicates that the pressure through a closed system is constant. One part of the system is a piston that behaves like a pump, with a moderate mechanical force acting on a small cross-sectional area.

The other part is a piston with a larger area that generates a corresponding mechanical force. Only a small diameter pipe - better withstanding pressure - is needed if the pump is separated from the press cylinder.

According to Pascal's Principle, the pressure in a confined fluid is transmitted without decrease and acts with an equal force in equal areas, at 90 degrees from the walls of the container. This causes a difference in the length of the stroke, which is proportional to the radius of the piston head areas.

A fluid such as an oil is displaced when each piston is pressed inward. Since the fluid cannot be compressed, the volume that that small piston displaces is equal to the volume that the larger piston displaces.
