Hydraulic presses are used in a wide range of industrial and manufacturing applications, such as forging, stamping, deep drawing and pressing. They use a fluid (oil) to generate a compressive force to shape and form different materials, including metals, plastics and composites. They are available in H- or C-frame designs, offering large working areas and stability to perform a specific function as per need. These presses are known for their high force-generating capacity, ease of use and accurate & consistent results. Raptor Supplies offers a wide range of these portable hydraulic presses from brands like Enerpac, Fervi, Dake Corporation and others, ideal for automotive, aerospace, metal fabrication and plastic processing industries.

We offer a wide range of hydraulic / arbor / C-clamp presses designed for applications in metal fabrication, cosmetic, pharmaceutical and glass manufacturing industries. For transforming metallic objects into sheets or thinning glass, these hydraulic press machines use a hydraulic cylinder to create a compressive force on the ram / piston which then transfers it to the fluid. Featuring a welded / bolted construction for maximum strength and durability, these hydraulic presses are offered in different frame capacities. Raptor Supplies offers a wide array of various hydraulic press manufacturers like Enerpac, Dake Corporation, Gray, Baileigh Industrial and OTC. For different applications, fixed / portable hydraulic press machines are available in movable, fixed, single-acting and double-acting cylinder options.
Working Mechanism
Hydraulic presses use a pump to pressurise fluid, typically oil, which is then directed into a cylinder.
The pressurised fluid then pushes a piston within the cylinder, creating a force that is transferred to a tool or dies attached to the cylinder.
The resultant force generated by the press can be used to shape or form metals and other materials.
These electric hydraulic presses can handle large and bulky items, and the table height can be adjusted for proper positioning using the included lifting chain.
They have three-point levers that allow users to control the ram with one hand.
Their dual-acting cylinder moves the ram throughout the downstroke and return, allowing for precise alignment and smooth movement in both directions.
These double-acting hydraulic presses compress workpieces during clinching, moulding, punching, deep drawing, metal forming and forging operations.
They feature welded construction with a Hydra-Lift bed for effortless vertical daylight adjustments and a roller head design for smooth movement.
These Enerpac electric hydraulic presses also include a hydraulic clamp for locking the frame in place.
Frequently Asked Questions
What is the difference between single-acting and double-acting hydraulic presses?
Single-acting presses have a single connection to a source of pressurised fluid and the other end is connected to a reservoir or return line.
Double-acting presses, on the other hand, have two connections to a source of pressurised fluid, wherein one connection helps the cylinder to extend and the other let it retract during the operation.
What is the use of an H-frame hydraulic press?
The H-frame consists of two pillars that support the cylinder and the upper and lower platens. This design allows them to create better stability for tasks like stamping, punching, bending, cutting, forging, deep drawing and straightening metals or plastics. In addition, H-frame presses offer high precision, easy maintenance and the ability to withstand large loads.
Where are movable and fixed cylinders used?
A movable cylinder moves about the press's frame where it needs to exert force on the workpiece. For example, in a stamping press, the cylinder moves downwards to apply force to the stamping die.
Fixed cylinders are used in presses, where the cylinder is fixed on the punching plate while the workpiece is placed on a bed. In operation, the gliding screw provides an upward force while the cylinder provides a downward force to the upper body, causing the punching machine to move downwards with a greater impact and cut / shape the workpiece.
