Gasbarre isostatic presses are optimized for reliable cold dry bag isostatic pressing. Cold isostatic pressing involves the compaction of powders encased in elastomer molds. 

Through this process, the mold is placed into a pressure chamber and filled with a room-temperature liquid before the press applies the pressure from all sides, condensing the metal powder. As a result, the powder particles mechanically bond to each other, creating a solid green body. Finally, the liquid is removed and the container expands to its original form so that the product can be retrieved.

There are two types of presses used for cold dry bag isostatic pressing — monostatic isostatic presses with single-cavity structures and densomatic isostatic presses with multi-cavity designs.

We carry reliable and innovative cold dry bag iso­static presses for powder compaction. Gasbarre’s SIMAC product line offers uniquely configured presses to allow for the laboratory or production manufacture of uniform density components. The dry bag design simplifies powder filling, compaction and ejec­tion and is more efficient, allowing for quick, ready-to-press parts.

SIMAC presses include a tool mounting system that allows for a wide range of parts to be produced in the same machine. Their dual inner bag configuration allows simple tool changeover.

Our monostatic presses comprise a single-cavity design suitable for research and development (R&D) as well as production needs. Our automation systems and in-line horizontal lathes are available add-ons. Gasbarre monostatic presses comprise the following characteristics:

• SINGLE CAVITY
• SEMI OR FULLY AUTOMATIC
• ADJUSTABLE DWELL
• BUILT TO FIT APPLICATION

Some of the key features of our monostatic presses include:

• Removable inner (product) tools.

Our cnc hydraulic presses are manufactured in capacities from 15 tons to 1,200 tons for single-level or multi-level parts for carbides, ceramics, powder metals, polymers and other particulate material industries. Gasbarre’s computer numerical control (CNC) hydraulic presses are optimized for reliable and lasting service with numerous innovative features and application capabilities.

What Are Servo Hydraulic Presses?

Hydraulic presses use hydraulic cylinders to produce a compressive force that aids in lifting and condensing large items. This equipment is optimized to perform various actions, including stamping, molding, punching, forging, clinching, metal and rubber formation, and powder compacting. 

CNC hydraulic presses play a role in numerous industrial applications, such as ceramics, car parts, aircraft, appliance and electrical component manufacturing.

How Do Hydraulic Presses Work?

Hydraulic presses operate on the principle of Pascal’s Law, which states that when pressure is applied to a confined fluid, it transmits that force across the entire solution, resulting in the same pressure change throughout. 

These machines are powered by manual, electric or pneumatic pumps and generate a fixed pressure that expands the cylinders. Hydraulic presses comprise two fluid-filled cylinders — a large one, known as the ram, and a small one, known as the plunger. The press operates by exerting force onto the plunger, which reacts by pressing the fluid beneath it. Then, the pressure evenly distributes and raises the ram. Once the pressure is dispersed between both cylinders, they work to condense the item placed between them.

Benefits of Using Hydraulic Presses

Using servo hydraulic presses in your automotive manufacturing facility means experiencing all the benefits of these powerful and reliable machines, including:

• Greater pressure, travel distance and position control.
• Minimal maintenance and repairs.
• Easily replaceable parts.
• Overload protection capabilities.
• Quiet operation.
• Smaller surface area for better space savings.

Why Choose Gasbarre for CNC Hydraulic Presses?

Movement of the press axes is performed by closed-loop control. Extreme precision and repeatability are the results.

What Are Electric Presses?

Electric powder presses are servo-powered equipment designed for compressing materials under high pressures. Because of their servo motors, these machines can control the output shaft’s positioning and speed rather than maintaining a fixed press cycle speed. Electric metal presses also use a closed looping feedback system to enable more precise cycle rate and load regulation and can perform all of the following functions:

• Inserting
• Clamping
• Press fitting
• Riveting
• Staking
• Crimping
• Joining
• Punching
• Swaging
• Spring testing

How Do Electric Powder Presses Work?

Like most presses, electric powder compaction presses operate by pressing a die or plate against a material using high pressures to deform it. Servo presses locate and deliver the product by pushing the upper or lower die or plate onto the piece using primarily hydraulic pressure.
