Large and Medium-Sized Cold Isostatic Presses

Large and Medium-sized Cold Isostatic Presses

Product Features

1. Work chamber diameter range: 300~900mm

2. Automatically detects whether the working fluid has filled the work chamber, eliminating the need to rely solely on preset refill times to control the refilling process.

3. Smooth exhaust from the work chamber during cover closing and fluid refilling, effectively reducing time delays caused by excessive air in the high-pressure chamber.

4. Automatically collects working fluid that overflows from the work chamber opening and returns it to the refill tank, reducing waste and keeping the environment clean.

5. Com prehensive multi-stage working fluid filtration system ensures more reliable equipment operation.

6. The intensifier controls internal plunger reversal through non-contact position sensors, resulting in lower noise and smoother pressure increases during plunger reversal.

4. Membrane switches are affixed to the control cabinet surface with graphical designs for intuitive operation.

Technical Parameters

Installation Methods

Ground Installation

Easy installation, unlimited maintenance space, does not alter the original factory structure, suitable for equipment with a total height of less than 4 meters.

Pit Installation

The operating surface is flush with the ground, convenient operation, does not occupy factory height, requires prior construction of a foundation pit.

Isostatic Pressing Process:
The isostatic pressing process involves placing the product in a closed container filled with liquid and applying equal pressure to all its surfaces. Under high-pressure conditions, the density of the product increases, and it attains the desired shape. With advancements in science and technology, isostatic presses are increasingly used for shaping high-temperature refractory materials, ceramics, hard alloys, rare-earth permanent magnets, carbon materials, and rare metal powders.

Characteristics of the Isostatic Pressing Process:

1. Utilizing an isostatic press for blank forming results in high and uniform density of the blank, with minimal shrinkage during firing and reduced deformation.

2. It enables the formation of slender rod-shaped or tubular blanks that are difficult to prepare using conventional compression molding processes.

3. The products exhibit high strength and good machinability, significantly reducing internal stress.

4. Mold fabrication is convenient, with a long service life and relatively low cost.

5. It allows for the formation of large-sized blanks, with the capability to press multiple blanks per cycle.

Forming Methods:

Single-step Forming:

The powder is loaded into a flexible rubber mold, which is then sealed. The sealed rubber mold is placed inside the high-pressure chamber of the equipment for pressing, resulting in a high-density green part.

Two-step Forming:
The powder is initially pressed using a conventional dry powder press. The pressed green part is then vacuum-sealed and placed inside the high-pressure chamber of the equipment for further pressing, yielding a high-density and uniformly dense workpiece.

The M-series is ostatic press consists of three main parts: the mechanical host, the booster station, and the electric control cabinet.

● The frame movement is mechanically limited, ensuring stable and reliable operation.

● The high-pressure chamber cylinder cover is designed integrally with the frame, allowing for accurate positioning during closure and significantly extending the service life of the high-pressure chamber port seal.

● The reciprocating booster offers high boosting efficiency.

● It automatically detects whether the working fluid in the high-pressure chamber is fully filled, ensuring no gas is present before pressurization.

● It can automatically recover the working fluid dripping from the cylinder cover and the liquid overflowing at the opening of the high-pressure chamber.

● The make-up fluid station is equipped with multiple filtration mechanisms to collect impurities in the working fluid.
