ASTM Plastic Molding Press
Models AutoFour/15PL-ASTM (4393) and AutoFour/30PL-ASTM (4394)
ASTM Rubber Molding Press
Model AutoFour/48-19-ASTM (5370)
Auto Bench Top 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.
Carver offers PM Servies/Calibrations/Troubleshooting on existing equipment. Please feel free to contact our Service Department for details at 260-233-6900 or via email.

(AutoFour/15PL-ASTM (4393) and AutoFour/30PL-ASTM (4394))
- Clamping force between the 2 models 15 or 30 (minimum 1,000 lbs)
- Adjustable Daylight 0″ – 13.5″ (Factory set at 4 ½”)
- Stroke 6”
- Four (4) fully threaded columns
- Self-contained 1/4 HP hydraulic unit
- Two (2) 12” x 12” electrically heated cored for cooling, Temperature range up to 343ºC (sized for 8 ºC/minute temperature rise, Platen & perimeter insulation, Programmed platen cooling per ASTM D-4703 Procedure C (formerly D1928 procedure C), Package includes platens designed for flood cooling, inlet and outlet manifolds and valves for platens, programmable temperature controls with ramp capability
- Programmable control system; 25 Programmable segments of clamp pressure, cure time and temperature per recipe, 250 recipe storage capability, Programmable in units of Kg, US Tons, Metric Tons & Pounds
- Two “anti-tie-down” close buttons for operator safety
- Interlocked safety enclosure with hinged door
- 230V 1-Ph supply voltage
- Electrical disconnect (non-fused)
- Dimensions: 50”L-R x 29.5”F-B x 61”H (uncrated)
- Weight: 1,050 pounds (uncrated)
The following calibrations certificates are provided with the press: Force & Temperature calibration of platen temperature controls by using equipment traceable to NIST (10 point check), Temperature uniformity of platens, Platen parallelism, Certification of timers in PLC.
The ASTM Catalog #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 180°C to 45°C. 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.
