cold isostatic press

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.

• 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.

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.

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.

The wearing parts of cold isostatic equipment are mainly various seals, such as various types of seal rings, valve cores and valve seats.

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.
