Cold Isostatic Pressing Supporting the Ceramics Industry

For decades, Cold Isostatic Pressing (CIP) has been used successfully by manufacturers around the world. CIP is used to consolidate metal- and ceramic powders to make a “green” part that can be further treated, i.e. rolling, machining or sintering.

With typical pressure from 1,035 to 4,138 bar (15,000 to 60,000 psi) and ambient temperature up to 93°C (200°F), CIP can achieve 95% of theoretical density for ceramics. For metals ~100% theoretical density is possible and also improve the ductility and fatigue resistance of critical, high-performance metallic materials. The components are often of net shape or near net shape configuration.

A proven process for high performance ceramic parts
Common applications for Cold Isostatic Pressing include consolidation of ceramic powders, compressing of graphite, refractories and electrical insulators, and other fine ceramics for dental and medical applications.The technology is expanding into new applications such as pressing of sputtering targets, coatings of valve parts in an engine to minimize wear of the cylinder heads, telecommunications, electronics, aerospace and automotive.

CIP of Advanced Ceramics for Highest Performance

Quintus Technologies’ patented fine decompression system to accurately and controllably lower the pressure and the cycle time, and to give the highest productivity. Benefits are reduced mechanical wear of valves, safe production due to the most accurate pressure control and minimized material losses due to entrapped air that will cause cracking and spalling of the “green” ceramic parts.

Quintus has the safest and lightest design on the market in accordance with ASME Section VIII, Division 3, “leak-before-burst”. The life time of our pressure vessels are the longest that are produced today. Most of our CIP-units are still in operation due to the unique wire-wound pre-stressed technology, that ensures easy inspection and longest maintenance intervals.

Improving life for the ceramic industry with our CIPs
Our CIPs are designed for unmatched performance and can handle the highest pressure and weight loads as well as the fastest cycle times. Extremely long life of the pressure vessel components. Advanced and intelligent pressure control with operator friendly HMI. Fine decompression system for accurate pressure control and possibility to continue the cycle in case of earth fault. The safest and redundant cooling and filter system to handle powder failures. It is THE system for safe operation.
