Bench Top Compression Molding Presses for Laboratory Applications from Carver, Inc.

Hydraulic bench top press for ASTM compression molding.

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 ±2°C cooling rate.

ASTM International Organizational Member

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.
