Cold Isostatic Presses (CIP), Wet Bag, and Molds – EPSI

EPSI, a world leader in custom-engineered high-pressure solutions, introduces its Cold Isostatic Press Production Unit (CIP). Designed for high productivity and low maintenance, EPSI’s Cold Isostatic Presses (CIP) are ideal for the ceramic, carbon, plastics, and powder metals industries and can be customized to suit application-specific needs. Cold Isostatic Presses (CIP) are capable of operating at pressures up to 100,000 psi (approximately 700 MPa). With control of pressurization and decompression, results lead to products of uniform density; reducing internal stresses, cracks, strains and laminations.

EPSI’s Cold Isostatic Presses (CIP) are available in a variety of sizes from pilot to large production units and feature top-closure and load-handling systems designed to meet the customer’s production requirements. Cold Isostatic Presses (CIP) are equipped with safety and alarm devices, adjustable pressure set-points, dwell time, and fluid drain settings. Cold Isostatic Presses (CIP) are available either threaded or yoke-framed.

Cold Isostatic Presses (CIP) also feature a hydraulically intensified high-pressure pump and a decompression circuit with low wear. High product production 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, yoke frame or threaded closure system, and a vertical or gantry top-closure system.
