Water Cooling Metallographic Hot Mounting Press Support Make 2 Specimens Simultaneously

Technical Data Download: iqualitrol Mounting Press iPress-891

Brief Introduction:

iPress-891 is used for setting up those irregular specimens, the specimens can be fixed in with the request of the surface, also can protect the edge and keep out of the abrasion.

The specimen size is limited by the semi-automatic or automatic Grinder/Polisher. In this case, mounting press is one of the necessary equipment in the metallographic lab. It fits of all thermosetting materials because of the cooling system.

iPress-891 can automatically operate with the heating, the holding time, and acting force. There are 4 diameters moulds according to the difficult specimens, and can make 2 specimens simultaneously.

Mounting of specimens is usually necessary to allow them to be handled easily. It also minimizes the amount of damage likely to be caused to the specimen itself.

The mounting material used should not influence the specimen as a result of chemical reaction or mechanical stresses. It should adhere well to the specimen, and if the specimen is to be electropolished later in the preparation then the mounting material should also be electrically conducting.

Specimens can be hot mounted (about 150 °C) using a mounting press either in a thermosetting plastic, e.g. phenolic resin, or a thermosoftening plastic e.g. acrylic resin. If hot mounting will alter the structure of the specimen a cold-setting resin can be used, e.g. epoxy, acrylic or polyester resin. Porous materials must be impregnated by resin before mounting or polishing, to prevent grit, polishing media or etchant being trapped in the pores, and to preserve the open structure of the material.

A mounted specimen usually has a thickness of about half its diameter, to prevent rocking during grinding and polishing. The edges of the mounted specimen should also be rounded to minimize the damage to grinding and polishing discs.
