CIP 1250 video

Cold Isostatic Press (CIP) is a core foundational equipment in modern materials science and powder metallurgy industry, and the CIP D420 X H1000/160MPA is Hongnuo's flagship Standard Model Press engineered for industrial-grade densification needs. This equipment applies ultra-high isotropic static pressure (up to 160MPa) to powder or prefabricated billets sealed in flexible molds at room temperature via a liquid medium, achieving uniform densification of materials. It effectively overcomes defects like uneven density and high internal stress in traditional unidirectional compression molding, and can be seamlessly integrated with our Automatic Pressing System to form a complete Production Line Press—catering to both cutting-edge scientific research and large-scale industrial production.

Unparalleled Uniform & Dense Effect

True isostatic pressing technology ensures pressure is evenly transmitted from all directions to every part of the workpiece, even for components with deep holes, grooves, or complex geometries. This achieves highly consistent density distribution from surface to core, significantly reducing deformation and cracking risks during sintering, and greatly improving product qualification rates and consistency—an advantage that makes our Standard Model Press stand out in the market.

Superior Material Adaptability

Optimized for processing a wide range of powder materials, our equipment is perfectly applicable to hard alloys, advanced ceramics (alumina, silicon nitride), graphite products, rare earth permanent magnet materials, metal injection molding (MIM) debinding blanks, and advanced refractory materials. Whether for small-batch R&D or mass production via a Production Line Press, it meets diverse industrial needs.

Robust & Reliable Core Design

The core pressure-bearing component (working cylinder) is made of high-quality high-strength alloy steel, manufactured via advanced forging and heat treatment processes. Combined with precise sealing technology and multiple safety protection systems (automatic overpressure relief, safety mechanical locks, electronic access control linkage), the equipment ensures safe and stable operation under long-term high-pressure cycles—providing lasting production guarantees for users.

Intelligent & Efficient Operation Experience

Integrated with an advanced Automatic Pressing System (fully automatic PLC control) and an intuitive HMI touchscreen, users can easily set, store, and call multiple pressure programs to achieve fully automatic pressurization, holding, and depressurization cycles. Real-time pressure curve display, data recording, and fault diagnosis functions reduce operational difficulty and support process optimization & quality traceability.

1. Mold & Material Preparation: Select a flexible mold matching the target material, fill it with powder/prefabricated billet, and ensure uniform material distribution to avoid initial density inconsistencies.
2. Mold Sealing: Hermetically seal the mold to prevent pressure medium infiltration, which is critical for maintaining material integrity during pressing.
3. Load into Working Cylinder: Place the sealed mold into the D420×H1000 working cylinder, ensuring proper positioning for even pressure transmission.
4. Parameter Setting: Use the HMI to set pressure (up to 160MPa), holding time, and depressurization rate—our Automatic Pressing System supports program storage for repeatable Production Line Press operations.
5. Initiate Pressing Cycle: Start the automatic cycle; the system fills the cylinder with pressure medium and applies isostatic pressure as programmed.
6. Pressure Holding & Depressurization: Maintain the set pressure to ensure full densification, then depressurize slowly to avoid workpiece damage.
7. Retrieve Finished Product: Remove the mold from the cylinder, open the seal, and take out the densified green product for subsequent sintering/processing.
