Bench Top 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.
