Metallographic mounting presses, MV Series

These easy-to-operate cold mounting vacuum presses produce excellent pore impregnation and well-supported samples with increased clarity and edge retention. They include a durable vacuum pump that supplies sufficient vacuum to evacuate entrapped air from any porous specimen. A freely adjustable 360° joy stick allows multiple moulds to be filled under vacuum from the attached epoxy cup holder and flow control.

MV01 is a high-capacity vacuum impregnation machine which offers an efficient and reliable solution for handling porous samples for metallographic specimen preparation. It effectively reduces bubble formation, which is crucial in the metallographic preparation process, especially for porous materials. Air bubbles could lead to voids or uneven distribution of the mounting resin in the sample, affecting edge preservation and the accuracy of subsequent metallographic observations. This makes MV01 an essential equipment for metallographic specimen preparation in laboratories and production lines.

MV02 is a specialised compact cold vacuum impregnation machine for metallographic specimen preparation, catering to the needs of small-scale and flexible sample impregnation in laboratories. This machine provides rapidly and effectively evacuates air residues from porous samples, optimizing edge preservation. As a result, subsequent metallographic observations and analysis yield accurate and reliable results. MV02 demonstrates significant application value in the preparation of samples from porous materials, providing reliable support for laboratory research and testing work.

Advantages of Vacuum Encapsulation/Impregnation with Epoxy Resin

Encapsulation is the immersion of samples in resin using a mould for the purpose of improving the external integrity of a friable or brittle samples and/or bonding separate fragments. Impregnation refers to the penetration of a porous sample to preserve its internal as well as external integrity. Epoxy-based resin works best for both impregnation and encapsulation. The lower the viscosity of the epoxy, the deeper it will penetrate into a sample and the better it will mechanically bond separated fragments.
