As leaders in high-pressure technology, we specialize in the design and manufacturing of advanced Isostatic Presses. Our systems—both Hot Isostatic Presses (HIP) and Cold Isostatic Presses (CIP)—are engineered to achieve full densification of powdered metals, ceramics, and composites, or to eliminate internal porosity in castings and 3D-printed metal parts. The result is components with superior material integrity, enhanced mechanical properties, and unparalleled reliability.
Custom-Engineered HIP and CIP Systems
We recognize that no single solution fits every application. That is why we are dedicated to providing fully customized Isostatic Presses tailored to your specific process requirements. Our engineering team works closely with you to define critical parameters, including:
Vessel Size: From compact laboratory presses for research and development to massive production systems with working zones several meters in diameter.
Pressure & Temperature: We design systems to achieve a wide range of pressures (up to 30,000 PSI / 200 MPa or higher) and, for HIP systems, temperatures exceeding 2,000°C.
Control Systems: We offer advanced, intuitive PLC-based control systems for precise cycle management, data logging, and operational safety.
Over 30 Years of Proven Manufacturing Expertise
The foundation of our company is our people. Our core technical and manufacturing team possesses over 30 years of hands-on experience exclusively in the isostatic pressing industry. This deep institutional knowledge translates directly into robust, safe, and efficient machine design. We have a profound understanding of the critical nuances of high-pressure vessel engineering, adherence to international safety codes (like ASME), and the complex interplay between materials, pressure, and temperature. This expertise ensures that every press we build is not only powerful and precise but also built to last.
By combining our deep-rooted experience with a commitment to custom engineering, we deliver Isostatic Presses that are complete, reliable solutions for today’s most demanding manufacturing challenges.
