Hot Mounting Press - OPAL 460

ATM’s OPAL 460 is a fully hydraulic, water-cooled hot mounting press for mounting samples prior to polishing. The process sequence is performed automatically. The completely automatic sliding closure allows rapid and easy opening/closing of the mold assembly. Mold assemblies can be exchanged swiftly and without the need for tools.

The sturdy aluminum construction is powder-coated. With its solid construction and ATM hydraulic system, the machine’s operating noise is reduced to a minimum. ATM’s full selection of mold assemblies from Ø 25.2-50 mm and different pressure techniques provide best conditions for mounting a sample. Two mounts can be produced simultaneously with the use of a spacer.

The OPAL 460 and 480 are available as single units as well as integrated in a bench. By incorporating the mounting presses into ATM’s System, a comfortable working height is created. Optionally, the System-Mounting Press can be fitted with a closed cooling water system, so that it becomes independent from any mains water supply. Furthermore, the water consumption is reduced to a single filling (6 l). The System-Mounting Presses are available as twin or triple powder-coated aluminum units and fit ideally into the ATM System Lab.
