    Carver 5370 AutoFour/4819 ASTM-NE-ASTM Molding Laboratory Press (48 Tons)


    The Carver 5370 “Auto-Four” press is a four post design with bolsters for maximum rigidity. Integral hydraulic power unit is completely self-contained and electrically operated. Fully programmable controls direct press functions and provide for recipe storage. Clamp area is fully guarded with interlocked operator gate.

    Chart Recorders for data acquisition are available for any of these three AutoFour ASTM Models. Chase Frame molds for pressing test plaques, Floor Stands and Chillers for controlled water cooling are available for the Plastic Model ASTM Presses (4393 & 4394).

    If your application requires multiple daylights or other specific specifications, please feel free to contact us for more information and/or a quotation to meet your specifications.

    The following calibrations and certifications are provided with the press: Pressure calibration and certification traceable to NIST (10 point check), Calibration of platen temperature controls (10 point check), Temperature uniformity of platens, Platen parallelism, Certification of timers in PLC

    The ASTM Catalog#’s 4393 and 4394 meet the more demanding requirements for molding test plaques in Class 5 polyethylene materials with “Auto-Four” bench top hydraulic compression presses, 15 or 30 tons clamp force. ASTM D4703 (formerly D1928) Procedure C demands accurate and controlled cooling from 180C to 45C. The “Auto-Four” presses have electrically heated 12” x 12” platens which are designed for automatic cooling.

    • Water Requirements: 8 10 GPM (approximate) at 50 psi and 8 13 deg C
    • Compressed Air Requirements: 0.5 SCFM at 80 psi (Required for platen cooling only)

    NOTE: Pressure step-down will relax the force to "0" and rebound to the next lower force setpoint. To run material class 1 thru 4 requires a constant water supply of 13 deg. C (55 deg. F.) To run class 5 material, a constant water supply of 8 deg. C (45 deg. F) is necessary. Water and air cooled chillers for providing the proper process water are available as an option.
