The Primary Components Of A Hydraulic Press

by Walter Smith

China is one of the leading hosts of the best hydraulic press suppliers in the market. The country hosts some of the most reliable manufacturers of hydraulic presses. These companies also manufacture parts of hydraulic presses. This post looks at the different parts of a hydraulic press and their functions.

Parts of a hydraulic press

The following are some of the primary components of a hydraulic press;

1. Safety door

The role of the safety door is to allow operators access to other components within the machine. This means that when accessories within the machine get damaged or fail to perform correctly, operators or repairers can access and fix them through the door. For this reason, some people refer to the safety door as the correction gate.

2. Limit switch

The role of this component is to keep particular objects from going past their predetermined position. When a hydraulic press is working, it often includes a lot of movement. This could cause objects to move from their original position. The limit switch restricts the movement to specified points.

3. Valves

A hydraulic press features two types of valves. They are;

  • Manual control valves- as the name suggests, this valve is typically controlled manually
  • Relief valves- the role of this component is to control and release pressure when it reaches high levels or exceeds certain limits

4. Pressure gauge

The role of the pressure gauge is to measure the pressure. It allows the operator to read the pressure levels when the machine is running.

5. Hydraulic cylinder

This component acts as a mechanical actuator. An actuator is a tool that is in charge of the movement of a mechanism. It is also responsible for controlling specific systems, like the opening and closing of valves. In a hydraulic press, the cylinder helps give a unidirectional force. This is achieved through a unidirectional stroke. This component is mainly made of steel.

6. Frame

The role of the frame is to hold the press together. It also helps give it strength and keep all its components intact. It is worth mentioning that there are different types of frame shapes for varying pressing applications. The frame is usually made from strong and durable material to provide the required strength.

7. Table

Also known as the bolster, the table is the part that supports the material. It is usually pressed and repositioned depending on how the materials need to be lined up with the press. It is also designed to accommodate different materials.

8. Pressing plate

The role of the pressing plate is to provide the necessary pressure to the object. Therefore, the plate needs to have high endurance and strength to accommodate its function.

9. Pump

This component uses the hydraulic fluid to create pressure for driving the cylinder.


It is worth noting that there are different types of hydraulic presses. This means that the components may differ from one type to the next. Regardless, a good hydraulic press features most of the standard components listed above. These components work together to enhance the performance of the machines.
