With many different press options on the marketplace it can be hard to decide which is right for your facility and application. Read below to understand the pros and cons of a mechanical press, servo press, or hydraulic press.
Mechanical Press
A mechanical press uses mechanical parts to complete their work and provides the greatest production speeds, especially when processing parts with shallow, simple requirements as is common in the automotive or parts industries.
Pros:
- Relatively inexpensive
- Fastest production
- High accuracy
- High repeatability
- Simple set up
- Available special slide motions (i.e. link motions)
- Variable slide velocity
- Energy efficient
- Fixed stroke length
Cons:
- Limited versatility with variable stroke length, die space, and pressure
- Lack flexibility
Hydraulic Press
The hydraulic press uses water to move pumps and cylinders. It does not generally achieve the high cycling speeds of a similar-sized mechanical press, but it does offer greater versatility with its variable stroke length, die space, and pressure. The hydraulic press is often the best choice when producing parts with deep, complex forms that require a lot of material flow and are not dependent on production speed. Parts such as tanks, cylinders, and bowl shapes are often run on hydraulic presses.
Pros:
- Full tonnage throughout the stroke
- Unlimited customization and flexibility
- Longer tool life
- Variable stroke length
- Variable slide velocity
- Full working energy at any speed
Cons:
- Slowest
- Lower accuracy and repeatability
Servo Press
The mechanical servo press offers much of the versatility of the hydraulic press, at production speeds often approaching traditional mechanical presses. The stroke, slide motion, slide position, and speed are programmable to allow many different combinations that can work with a wide variety of dies, part types, and production speeds.
Pros:
- High accuracy and repeatability
- Full press capacity near bottom dead center of stroke
- Variable stroke profiles
- Precise slide motion and position control throughout the range of the stroke length
- Variable, precise slide velocity control, even within a single cycle of the press stroke
Cons:
- High initial cost
