Electric cold isostatic press for powder

The Electric Cold Isostatic Press (ECIP) is an advanced powder compaction device widely used in the molding and pre-treatment of ceramics, metal powders, composite materials, and other fields. By uniformly applying multi-directional pressure within a sealed mold cavity, the ECIP can compact powder materials into high-density, complex-shaped pre-formed parts at room temperature, without heating, making it particularly suitable for processing heat-sensitive materials.

Product Description：

The CY-CIP-30MA Electric Cold Isostatic Press operates by placing the workpiece in a closed container filled with liquid. When the device is activated, the liquid applies equal pressure on all surfaces of the sample. Under high pressure, the material’s density increases, the gaps between powder particles shrink, and the desired shape is achieved. With the advancement of science and technology, and in-depth research on powder materials, cold isostatic presses are becoming increasingly used in powder metallurgy, composite materials, refractories, ceramics, hard alloys, and other material molding processes. The CY-CIP-30MA Electric Cold Isostatic Press is designed for research departments in universities and research institutes that need small sample materials, featuring compact size, reliable operation, and simple operation.

Product Features：

Multi-directional Uniform Pressure: Applies isostatic pressure (typically 100-400 MPa) within a sealed space to ensure material density and uniformity.

Electric Drive: Uses a servo motor-driven hydraulic system for high efficiency, low energy consumption, and stability.

Room Temperature Operation: No heating required, avoiding thermal deformation, making it especially suitable for processing heat-sensitive materials.

High-Precision Control: Equipped with a digital control system, allowing precise adjustment of pressure, time, and speed as required.

Application Case: 《Using Electric Cold Isostatic Press to Prepare Dielectric Ceramics》

Process Steps：

1. Material Preparation

Select ceramic powder: Choose suitable materials, such as alumina (Al₂O₃), barium titanate (BaTiO₃), and lead zirconate titanate (PZT), based on the required dielectric properties. These powders should have good flowability and appropriate particle size.

Add additives: Add binders, lubricants, dispersants, and other auxiliary materials as needed to improve powder flowability and uniformity during pressing.

2. Mixing and Ball Milling

Mix: Uniformly mix ceramic powders and additives, typically through ball milling or mechanical stirring. Ball milling helps improve powder uniformity and ensures the binder and additives are evenly distributed on the powder surface.

Control humidity: Maintain appropriate humidity levels to avoid particle agglomeration, which could affect pressing quality.

 3. Pre-Forming

Mold forming: Place the mixed ceramic powder into molds and form preliminary green bodies through simple pressing or heating treatments. This step provides initial shape and stability for the body, facilitating the subsequent cold isostatic pressing process.

Wet pressing (optional): If higher density is needed, wet pressing can be performed at this stage to compact powder particles further.

4. Electric Cold Isostatic Pressing

Load the sample: Place the prepared ceramic powder sample into the cavity of the Electric Cold Isostatic Press, ensuring uniform distribution and a flat surface.

Set parameters: Adjust pressing parameters according to the ceramic material’s characteristics, including pressing pressure (typically 100-400 MPa), pressing time, etc.

Cold isostatic pressing: Start the machine to uniformly apply isostatic pressure to the ceramic powder. The pressure will be evenly transferred in all directions, promoting better particle contact and increasing density.

Sintering (High-Temperature Treatment)

Drying before sintering: If binders or additives are used, dry the green body to remove moisture and organic materials, preventing bubble formation during sintering.

Sintering: Transfer the cold isostatically pressed body into a sintering furnace. The sintering temperature typically ranges from 1000-1600°C, depending on the ceramic material type and particle size. During sintering, the ceramic particles will expand and fuse, achieving the desired density and mechanical properties.

5. Cooling and Inspection

Cooling: After sintering, slowly cool the sample to prevent thermal cracking.

Inspection: Perform performance testing on the sintered ceramics, such as mechanical strength, dielectric constant, and dielectric loss. Microstructural analysis can also be conducted to examine the ceramic's crystalline structure and density.

6. Post-Processing and Finishing

Surface treatment: If needed, perform surface polishing, grinding, coating, or other treatments to improve appearance and performance.

Final inspection: Conduct a final performance inspection to ensure the ceramics meet specific application requirements, such as dielectric properties and mechanical strength.
