EPSI, a world leader in custom-engineered high-pressure solutions, introduces its Warm Isostatic Press Production Unit (WIP), a press with a high-pressure vessel and pressurized fluid heating to 300°C (572°F). Designed for high productivity and low maintenance, EPSI’s Warm Isostatic Presses (WIP) are ideal for all applications requiring moderate temperature during the application of pressure and can be customized to suit application-specific needs. The Warm Isostatic Presses (WIP) are capable of operating at pressures up to 100, 000 psi (approximately 700 MPa), with control of pressurization and decompression. This results in products of uniform density; reducing internal stresses, cracks, strains and laminations in the parts being processed.

The Laboratory Cold Isostatic Press (CIP) also features a hydraulically intensified high-pressure pump and a decompression circuit with low wear. High product repeatability is obtained through the use of elastomer molds. The CIP offers an automated fast fill and drain circuit with a low-pressure transfer pump. Configurations available on the CIP include; a low-pressure decompression system, a yoke frame or threaded closure system, and a vertical or gantry top closure system.

EPSI, a world leader in custom-engineered high-pressure solutions, offers its Dry Bag Cold Isostatic Press (CIP) Production Unit. Designed to produce large volumes of small parts, EPSI’s Dry-Bag CIP is ideal for the ceramic, carbon, plastics and powder metal industries for near net and net shape parts. EPSI’s Dry-Bag is equipped with the capability to change tooling to produce parts of various dimensions on the same press. With a fast cycle time of 20 to 60 seconds and a powder fill diameter of 50-250 mm (2 to 10 in.), the Dry-Bag CIP can be used to manufacture grinding balls, valves, tubes, rods, nozzles and implants. The Dry-Bag CIP can also press small balls with a diameter up to 30 mm (1 to 2 in.) in a capacity of 100 parts per minute and may be custom built for larger parts up to a filling diameter of 250 mm (10 in.) and a length of 700 mm (27.5 in.). EPSI collaborates with the German company, Frey GMBH, to produce its Dry-Bag CIP.
