    Carver 4391-ASTM, Model 12-12H-ASTM Compression Molding Press (12 Tons)


    Manual ASTM Press for Testing Specimens of Plastics, Elastomers and Other Thermoplastic Materials.


    Model 12-12H-ASTM Catalog #4391-ASTM


    The Manual ASTM Model 12-12H-ASTM (catalog# 4391) was designed to perform the ASTM compression molding of test plaques 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 (formerly D1928, Procedure C). This compression molding press is equipped with heating and manually water cooled platens and a programmable digital controller which has a heating/cooling loop for each platen and built-in program for the required 15/minute 2C cooling rate.

    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, and Platen parallelism.

    NOTE: 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.
