ASTM Presses for Testing Specimens of Plastics, Elastomers, Rubber Samples and other Thermoplastic Materials

These Carver “Auto-Four” presses are 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 factory for more information and/or a quotation to meet your specifications.
