There are many different factory presses to choose from, and finding the right press for your needs means matching the functionality and design of the press to the needs of your process. It’s important to assess your process first, so you know what to look for in a press, and then assess the different options available, so you can find the right fit.
As you assess your process, look for the following:
The following are a few of the most common presses used in manufacturing and assembly operations. We’ve selected these press types because of their versatility, functionality, stability, and power, which makes them ideal for a variety of different manufacturing and assembly tasks.
The C-frame hydraulic press is a versatile choice for manufacturing and assembly. Its open-front design allows easy access to the work area for easier die changing or adjustments and also for material loading, making it suitable for a variety of tasks such as bending, stamping, and forming. Since these presses are often smaller than 2 or 4-post presses by design, they are great choices when you’re dealing with limited floor space but still need the power of full hydraulic force. These presses are typically lower in cost compared to 2 and 4-post hydraulic presses as well.
Hydropneumatic presses are also available with a C-frame design. Air-over-oil presses can provide between 2.5 and 50 tons of force, allowing these models to accomplish many of the same jobs as hydraulic presses.
For heavy-duty applications, 2 or 4 post hydraulic presses provide stability and strength. The vertical posts on each side of the working area can either be structural, or have a guided platen that moves along the posts for perpendicularity. In either case the hydraulic cylinder or cylinders are typically mounted at the top of these posts.
With non-guided 2- or 4 – post hydraulic presses, the structural configuration simply offers more room for larger pieces of working material. Guided systems provide an even surface area of pressure, exerting force horizontally along the surface area of the guided platen, ensuring perpendicularity for tasks that require a consistent and uniform application of force. These configurations may be required for punching several dies from a sheet of metal, foam or plastic, or for other applications like metal forming and pressing over a large surface area.

The following presses are not full hydraulic presses, but they fit the bill for jobs and applications that require hydraulic power and often come with higher efficiency and lower cost and maintenance, so they are worth mentioning in the same vein. These are hydropneumatic presses, the first of which is something uniquely designed to function just like hydraulic, with a higher return on ROI.
A hydropneumatic press is a great alternative to a purely hydraulic press for manufacturing and assembly. The Air Hydraulics line of AH-Series Hydropneumatic Presses provide a range of 4 to 50 tons of force. Since this model combines pneumatic and hydraulic forces, it works faster than a purely hydraulic press, and also requires less maintenance and initial investment. This model’s rapid, low-force approach stroke uses a hydraulic-intensified half-inch power stroke, providing a strong finish to a steady procedure, and also provides a low-cost, energy-efficient alternative to a single or 3-phase high voltage hydraulic power unit.
While most hydropneumatic presses deliver intensified power within a half-inch of the cylinder stroke, air-over-oil presses designed with full power strokes like our unique C-Series Air Hydraulics Presses, can be the perfect alternatives to medium force hydraulic presses.
These presses combine the advantages of hydraulic and pneumatic systems, offering a full power stroke like their hydraulic counterparts, but using compressed air for the return stroke, providing efficiency and speed. The full powerstroke air-over-oil model press provides between 2.5 and 15 tons of force, with pressure maintained throughout the entire stroke. This type of press is ideal for bushing or bearing insertion, press fit, stud insertion, and many other manufacturing and assembly tasks. These presses provide the force of a hydraulic press, with reduced maintenance demands, increased speed, quieter operation, no high-voltage power requirements and a lower upfront investment cost.
