The ASTM Catalog#’s 4393 meet the more demanding requirements for molding test plaques in Class 5 polyethylene materials with “Auto-Four” bench top hydraulic compression presses, 15 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.
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
