A Double Action Hydraulic Press is designed for manufacturing operations where controlled forming, deep drawing, and consistent pressure are required. Unlike a basic single-action press, a double-action system generally uses separate movements for the main ram and blank holder. This provides better control over the workpiece during forming and is especially useful for sheet-metal components with deeper or more complicated shapes.

For manufacturers searching for a Double Action Hydraulic Press in Delhi, selecting the machine should involve more than checking tonnage. Material type, component dimensions, drawing depth, die size, blank-holder force, stroke, daylight, production volume, and automation requirements all need to be considered before finalizing the machine.

What Is a Double Action Hydraulic Press?

A double-action hydraulic press uses two hydraulic actions during the forming cycle. The primary ram applies the main forming force, while the second action controls the blank holder. During deep drawing, the blank holder keeps the sheet properly positioned while the punch moves the material into the die.

This controlled material movement is one of the main reasons manufacturers use double-action presses for demanding forming applications. Incorrect blank-holder pressure can lead to problems such as wrinkles, excessive thinning, or inconsistent component shapes. Therefore, the hydraulic system and die arrangement need to be selected according to the actual application.

Parrytech Hydraulics manufactures double-action hydraulic deep-draw presses in different capacities. Its published specifications range from 100-ton to 1000-ton models, with heavy-duty deep-drawing presses available up to 4000 tons. The company also states that presses can be manufactured according to customer requirements.

How Does a Double Action Hydraulic Press Work?

The operating cycle starts when the workpiece or metal blank is positioned over the die. The hydraulic power unit supplies pressurized oil to the cylinders to generate the required force.

The blank holder first applies controlled pressure to the material. The main ram then moves the punch downward, forcing the sheet into the die cavity. During this movement, the blank holder controls the flow of material and helps maintain the required shape.

Once the forming operation is completed, the hydraulic system controls the return movement of the ram and blank holder. The exact sequence can be adjusted according to the component, material, die arrangement, and production requirements.

Parrytech’s double-action deep-draw press specifications include PLC-controlled operation, Yuken/Rexroth solenoid valves, Polyhydron pre-fill valves, and ABB/Havells motors. Its listed models operate at a working pressure of 210 bar, with different combinations of capacity, stroke, daylight, blank-holder capacity, and platen size.

Main Components of a Double Action Hydraulic Press

Understanding the main components helps manufacturers evaluate a machine before purchase.

Hydraulic Cylinders

The cylinders generate the pressing and blank-holder forces. Their capacity and stroke must match the required forming operation.

Main Ram

The main ram carries the punch and provides the primary forming force required to shape the workpiece.

Blank Holder

The blank holder controls the sheet during deep drawing. Its pressure needs to be suitable for the material and component geometry.

Hydraulic Power Unit

The hydraulic power unit supplies pressurized oil to operate the cylinders. Pump selection, pressure, oil capacity, valves, and filtration all contribute to reliable machine operation.

PLC Control System

A PLC can control the machine sequence and make repeated production cycles more consistent. Parrytech’s double-action deep-draw press is listed with PLC-controlled operation.

Die and Platen Area

The platen or bed size determines the available working area for tooling. Manufacturers should ensure that the machine’s bed dimensions are compatible with the required die.

Applications of Double Action Hydraulic Press

Double-action presses are widely used for industrial forming and deep-drawing applications. Typical uses include:

• Kitchen sink manufacturing
• Cooking hob production
• Cooker and cookware components
• Automobile components
• Fire extinguisher bodies
• Metal containers
• Electrical components
• Sheet-metal forming
• Industrial deep-drawn parts

Parrytech Hydraulics offers a broad range of deep-drawing equipment, including presses with blank holders, die cushions, industrial deep-drawing systems, cooking hob presses, SS kitchen sink presses, and fire-extinguisher deep-draw presses.

This variety is useful for manufacturers because different components require different forming arrangements. A sink, for example, may have very different drawing requirements from an automobile or industrial component.

Benefits for Manufacturers

Better Control of Material Flow

The blank holder provides additional control over the sheet during forming. This is particularly valuable for deep-drawing operations.

Consistent Production

Once suitable hydraulic pressure, stroke, speed, and blank-holder settings are established, the machine can repeat the forming cycle consistently.

Suitable for Deep Drawing

The separate hydraulic actions make the press suitable for applications where controlling material movement is important.

Flexible Capacity Options

Manufacturers can select machine capacity according to the required forming force. Parrytech’s published range demonstrates configurations from 100 tons through 1000 tons, with higher-capacity presses available for heavy-duty requirements.

Custom Machine Configuration

Production requirements vary from one manufacturer to another. For this reason, factors such as bed size, stroke, daylight, blank-holder capacity, motor power, and control system can be selected according to the application.

Improved Process Control

PLC-based controls can help operators manage machine sequences and repeat production cycles more efficiently.

What Should Manufacturers Check Before Buying?

Choosing a hydraulic press only by its tonnage can create problems later. Manufacturers should evaluate the complete application.

1. Material: Identify whether the machine will process mild steel, stainless steel, aluminium, or another material.

2. Component size: The finished component dimensions influence the required bed and die size.

3. Drawing depth: Deeper components may require greater stroke and better blank-holder control.

4. Required force: Calculate the forming force instead of automatically selecting the highest available tonnage.

5. Blank-holder force: Ensure that the blank-holder capacity is suitable for the material and tooling.

6. Stroke and daylight: These determine whether the required die and component can be accommodated.

7. Automation: Decide whether manual, semi-automatic, or PLC-controlled operation is appropriate.

8. Hydraulic components: Check pumps, valves, cylinders, filtration, oil tank, and pressure-control arrangements.

9. After-sales support: Installation, commissioning, maintenance, training, and breakdown support should also be considered.

These practical factors help manufacturers select a machine that fits the production process instead of purchasing a press based on capacity alone.
