Hydraulic Compression Plastic/ASTM Presses for PE Sample Preparation
Plastic ASTM Presses
No. 3710-ASTMModel CMG30H-12-ASTM (Model “B”)
Specially configured to perform compression molding of test plaque, bar specimens, polyethylene and other thermoplastic resins.
Carver ASTM presses are specially configured to perform the compression molding of test plaque or bar specimens of Type I, II, III, IV or V polyethylene and other thermoplastic resins. The procedure is in conformance with ASTM Method D 4703, Procedure C. The presses are equipped with heating/cooling platens and a programmable digital controller which has a heating/cooling loop for each platen and built-in program for the required 15°/minute +/-2°C cooling rate.

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.
