Introduction
The round bidirectional press mold is a specialized tool used in high-pressure molding processes, particularly for creating intricate shapes from metal powders. This mold is designed to accommodate various shapes, including round, square, rectangular, and hexagonal, by utilizing different mold inserts. The process involves hydraulically applying pressure to a liquid-filled chamber containing the metal powder, which results in the mechanical bonding of the powder particles to form a solid green body. This technique is essential for producing components with large cross-sectional areas or requiring high pressures. The mold also features electric heating capabilities to facilitate the heating process within the tablet, enhancing the molding efficiency and product quality.
Applications
The round bidirectional press mold is versatile in various industrial applications, particularly in the fields of powder metallurgy, rubber molding, and diffusion bonding. This equipment is essential for creating precise shapes with high pressure and uniform heating, making it suitable for a wide range of products and processes.
- Powder Metallurgy: Used for molding powders into complex shapes with large cross-sectional areas under high pressure.
- Rubber Molding: Employed in compression molding, transfer molding, and injection molding processes to shape rubber products.
- Diffusion Bonding: Utilized in large-scale bonding of metal parts, ensuring uniform pressure distribution across extensive surfaces.
- Ceramic Molding: Applicable for pressing ceramic powders into intricate shapes, requiring high pressure and precise temperature control.
- Pharmaceutical Tableting: Used for compressing pharmaceutical powders into tablets, involving electric heating of molds for uniform heating during the tabletting process.
- Advanced Materials Processing: Essential for manufacturing advanced materials where precise pressure and temperature control are critical.
These applications highlight the versatility and critical role of round bidirectional press molds in various high-pressure and high-temperature industrial processes.

Operation steps
Two way pressurized cylindrical open mold is suitable for samples with high density requirements for powder pressing.
1.Assemble the die according to the operation diagram and install the sample in the cavity.
2.Put the die in the center of the hydraulic press and pressurize to required pressure.
3.Assemble the die according to the release diagram ，eject the sample out of the die bushing with the screw rod.
4.Take out the die from the hydraulic press , and remove the sample gently.
Advantages
- Enhanced Pressure Distribution: The round bidirectional press mold utilizes a multi-cylinder system with large pressing plates, ensuring uniform pressure across the entire surface. This is particularly beneficial for large parts, up to approximately 3 feet x 4 feet, which is significant for diffusion bonding processes.
- Independent Cylinder Control: Each hydraulic cylinder can be controlled independently, allowing for precise adjustments based on pressure transducer readings. This feature ensures that even over large areas, the pressure remains consistent, minimizing defects such as flow lines, blisters, or unfilled parts.
- Improved Stability and Uniformity: The bidirectional pressing method compacts the sample from both sides, resulting in enhanced stability and uniformity. This is crucial for subsequent processing stages and ensures the integrity of the final product.
- Versatility in Part Sizes: The press mold can accommodate a wide range of part sizes, making it versatile for various applications. This flexibility is particularly advantageous in industries where parts of different dimensions are commonly used.
- Reduced Dimensional Variability: Although initial setup may require some trial and error, the process once established becomes highly repeatable. This is beneficial for producing parts with specific dimensions, such as long aspect ratio pellets used in industries like automotive (e.g., spark plugs).
FAQ
What is a Round Bidirectional Press Mold used for?
How does the mold ensure even distribution of pressure?
Can custom molds be designed and produced?
What happens if there is uneven pressure during the molding process?
What is cold isostatic pressing (CIP)?
Cold Isostatic Pressing (CIP) is a process used to compact and mold powders and other materials into a desired shape by applying hydrostatic pressure at room temperature. The process is performed using a flexible mold, typically made of rubber or plastic, that is filled with a liquid pressure medium such as water, oil, or a specialized fluid.
How do you prepare pressed pellets for XRF?
What are the advantages of cold isostatic pressing?
- High green strength: Machining of the compacted material in its green state becomes more feasible.
- Materials that are hard to press: Isostatic pressing can be performed on powders without the need for water, lubricants, or binders, making it applicable to a wider range of materials.
- Predictable shrinkage during sintering is achieved due to the high compaction and uniform density.
- Time and cost savings in post-processing are possible due to the ability to create large, complex, and near-net shapes.
- Large aspect ratio parts with uniform density can be produced, resulting in improved quality.
- Green strength enables efficient in-process handling and treatment, reducing production costs.
What is a cold isostatic press?
A cold isostatic press (CIP) is a machine used to compact and mold powders and other materials into a desired shape.
The process works by filling a flexible mold, usually made of rubber or plastic, with a liquid pressure medium like water, oil, or a specialized fluid. This mold is then placed in a closed container, and equal pressure is applied to each surface to achieve a high-pressure environment.
The pressure results in an increase in the product's density and allows it to take on the desired shape.
Cold isostatic pressing is performed at room temperature, in contrast to hot isostatic pressing which is carried out at higher temperatures.
What pressure should XRF pellets be?
Application field of cold isostatic press?
Cold Isostatic Pressing is widely used for various applications, including the consolidation of ceramic powders, compression of graphite, refractory materials, and electrical insulators, as well as the production of fine ceramics for dental and medical applications.
This technology is also making inroads into new fields such as pressing sputtering targets, coating valve parts in engines to reduce wear on cylinder heads, telecommunications, electronics, aerospace, and automotive industries.
What is the advantage of XRF pressed pellet technique?
What are the wearing parts of cold isostatic pressing equipment?
The wearing parts of cold isostatic equipment are mainly various seals, such as various types of seal rings, valve cores and valve seats.
Do you provide matching cold isostatic press molds?
We offer a variety of standard mold shapes for customers to experiment or validate their process. Custom mold design services are also available upon request.
