Mechanical Press vs Hydraulic Press: Which One Is Right for You

Durmark

A press is a machine that processes or shapes various materials. It can process a variety of metal materials, including forging, die-cutting, stamping, etc.

Today, there are many types of press machine on the market. But it is mainly divided into two categories: mechanical presses and hydraulic presses.

"Then what type of press should I choose? What is the difference between a mechanical press and a hydraulic press?" This is a question from many customers.

Therefore, although these machines have the same purpose, it is very important to understand the difference between them and choose the right press to get more benefits for your operation and production.

This article will take you to understand the difference and choice between hydraulic presses and mechanical presses, I hope it will be helpful to you.

 

Working principle of mechanical press

Obviously, mechanical presses generate power mechanically. The principle of the mechanical press is that the main motor drives the flywheel, and the clutch drives the gear, crankshaft, connecting rod and other components to complete the linear movement of the slider.

The components of the mechanical press are all interrelated, so that the mechanical press can produce higher production speed and productivity. The simple setup and operation of the mechanical press brings fast and efficient repetitive effects.

At the same time, the components of the mechanical press are interrelated, which limits its application.

 

The working principle of hydraulic press

Unlike mechanical presses, hydraulic cylinders replace the movement of parts of hydraulic presses. The hydraulic pump moves the piston to increase the pressure of the internal liquid, and then the cylinder moves along the axis to press the pressure head onto the workpiece.

The pressure that a hydraulic machine can generate depends on the working pressure and the size of the cylinder diameter. And each axis will be independently controlled, which means that the hydraulic press has excellent flexibility compared to the mechanical press, and you can perform more flexible operations to complete more complex tasks.

 

Differences between functions and applications

We mentioned above, the working principle of mechanical presses and hydraulic presses. Obviously, their functions are similar, but their characteristics are different.

The hydraulic press is more flexible and has a wider range of uses;

The speed and production speed of the mechanical press are more excellent, and the operation is simpler.

Advantages and disadvantages of mechanical presses

Advantage

  • easy to use

    Because of its linkage, the mechanical press makes its operation requirements and settings simpler and lowers operating costs.

  • high productivity

    The mechanical press is a high-speed machine, suitable for fast and mass production.

  • Maintain clean and environmentally friendly

    The mechanical press does not use hydraulic oil, so there is no leakage and environmental protection issues.

  • Larger tonnage at the bottom

    Compared with hydraulic presses, mechanical presses can achieve larger tonnage in a smaller stroke.

 

shortcoming

  • High maintenance costs

    The internal components of the mechanical press are very expensive, and maintenance costs also need to be considered.

  • Application is not flexible enough

    Because of its mechanical linkage caused the limitation of the fixed stroke, limiting its application. Although some manufacturers have presses with adjustable strokes.

 

Advantages and disadvantages of hydraulic press

Advantage

  • Flexible operation

    As the stroke length is variable, the sliding speed can be changed, and the entire sliding movement and position can be controlled, which brings more extensive applications. At the same time, the customization of hydraulic presses is more flexible.

  • Relatively cheap maintenance

    The components of the hydraulic press are cheaper than the components of the mechanical press.

  • Same tonnage throughout

    The maximum pressure can be generated at each position in the stroke, which allows more operations during operation, including stroke, pressure setting, and so on.

 

shortcoming

  • Relatively low production speed

    Although the production cost is lower, compared with mechanical presses, it usually reduces output, accuracy and repeatability. Because the cylinder and fluid are not designed for rapid production.

  • Hydraulic oil leak

    Common faults of hydraulic machinery and hydraulic oil leakage are headaches. It may be the production environment of the factory, even the soil and groundwater.

 

Finally - Should I choose a hydraulic press or a mechanical press?

Although the two types of machines have the same purpose, they have their own characteristics. Therefore, before buying, please determine the attributes of the products you need to produce, and determine the speed, output, cost and functionality of the production machines you need. Choosing the right press can fight for greater economic benefits for you.
