CARVER Auto-Four Press for ASTM Test Sample Molding
CARVER Auto-Four Press for ASTM Test Sample Molding
Carver, Inc. meets the more demanding requirements for molding test plaques in Class 5 polyethylene materials with two new “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 180°C to 45°C. The “Auto-Four” presses have electrically heated 12” x 12” platens which are designed for automatic cooling with closed loop water or air cooled chiller systems.
These Carver “Auto-Four” presses are four post design with cast iron 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.
Optional equipment for the “Auto-Four” includes chart recorders for data acquisition, chase frame molds for sample test plaque molding, and chillers for controlled cooling water. Multiple daylights are also available. The new presses maintain capabilities for Class 1 through Class 4 materials.
