Cold Isostatic Pressing (CIP) is a widely used process for consolidating metal, ceramic, plastic, and composite powders. Wet bag CIP is performed using rubber molds, which can be manufactured to intricate shapes and various sizes. This creates uniform density throughout the green body, resulting in predictable shrinkage during subsequent sintering or HIPping. CIP can form parts that are too complex for uniaxial die presses. Additionally, CIPed green bodies can be machined easily prior to firing. Wet bag presses are capable of processing molds of different sizes, multiple bags simultaneously, and even very large parts. Most materials compact in the range of 10,000 to 40,000 psi. A research system with a 60,000 psi capability allows testing to be done prior to scale up. AIP research systems are extremely simple and economical, allowing organizations to own one or more systems in-house. AIP Cold Isostatic Presses make an excellent addition to any facility, providing safety and reliability.
Wide array of systems available from American Isostatic Presses. ASME designed monolithic (one piece forging) vessels with Full Thread, Partial Thread (Breech), Pin type or Yoke held closures. Safe, proven, durable, and cost effective. These vessels are easily inspected, maintained, and accepted for use in most locations. ASME stamping is also available.

Cold Isostatic Press Systems with pin closure vessel
AIP3-12-60CP RESEARCH CIP
Simple. Easy to operate. Easy to maintain. Safe, cost effective pressing. Working pressure 60,000 PSI. Vessel type: single ended, single wall one piece 4340 forging. Closure type: threadless quick opening pin type and air over oil lift cylinder. Microswitch head in place detection. Brass anti-extrusion backup seal with elastomeric o-ring. Working size: 3” diameter x 12” long. Pump: Haskel, 60,000 psi, air-operated positive displacement liquid pump. Approximate pump up time 5 minutes. Controls: Allen Bradley Micro Logix PLC digital pressure controller with Automation Direct touch interface. Stellar 60,000 psi pressure transducer. Piping and valves: 60,000 psi rated, with replaceable Stellite tip and stem on valve. Rupture type safety head assembly. Plexiglas reservoir. Air filter with regulator and pressure gauge.
Forged aircraft quality 4340 monolithic (one piece forging) vessel with pin closure top cover. The closure is lifted automatically by an air over oil cylinder. This is safer and more smooth than a strictly pneumatic actuated cover.
Safe, proven, durable, and cost effective. These vessels are easily inspected, maintained, and accepted for use in most locations. Optional materials and ASME code stamping are also available at additional cost.
The system is rated for 60,000 psi working pressure. The vessel is protected by a mechanical rupture disk to prevent potential overpressure of the vessel. Additionally the pump is limited by an adjustable air pressure regulator.
The vessel interior working size is 3" diameter x 12" long. Standard optional lengths are 3x8, 3x12, 3x16, 3x22 inches. Any custom size can be ordered.
The control system features a programmable logic controller that is easily programmed using the touch screen interface. Featuring a large digital pressure readout that is programmable to control pressure and shut off the pump at setpoint.
AIP offers any style of optional controls or computer to operate the system, with fully automatic or manual operations. Various venting options are also available for different applications including automated let down and multiple stage vents.
The system comes with an air driven Haskel pump, Model DFHX 602 capable of 60,000 psi. It is driven by a customer supplied air source. The speed of the pumping is directly related to the size of the customer air source.
Other air powered or electric-hydraulic powered types are offered. Brands include Hydro-Pac, Haskel, Hofer, Maximator, and Hydraulics International.
Warm Isostatic Press (WIP) Systems
AIP designs and builds Warm Isostatic Presses for many applications. These system can be gas or liquid pressurized and are often used for plastics and laminated products. WIPs are usually purpose built and can be low pressure all the way to extreme pressures. Liquid WIP systems range to 250 C and gas WIP systems can go to 500 C. Both cold and hot wall versions can be supplied. AIP has worked with many companies to also develop the molding and technologies required to make the process cost effective and possible. AIP has toll WIP capabilities and can offer testing to interested parties.
