Mounting Machines

Items available on this section:
Metapress-P
Metapress-A
Metapress-M
Summary Table

After cutting the specimen, the next step is mounting. The aim of mounting is to handle small or odd shaped specimens and to protect fragile materials, thin layers or coating during preparation as well as to provide good edge retention. Mounting produces specimens with uniform size so that it is easier to handle in automatic holders for further preparation steps.

Basically, two methods are available:

• Hot Mounting
• Cold Mounting

In hot mounting, the specimen is mounted under heat and pressure with a hot mounting press.

Cold mounting is preferred for samples which are sensitive to damage from heat and pressure (like coatings, PCB, etc.) Cold mounting resins are easy to use and require mixing which is then poured into a mould and allowed to set.

Summary Table for Grinding and Polishing Machines

In order to obtain a highly reflective surface that is free from scratches and deformation, the specimens must be carefully ground and polished before they can be examined under the microscope.

FORCIPOL Series of instruments are available as Single wheel and Dual wheel Units (200/250/300 mm wheel size). Both single or double wheel versions are available with constant, dual or variable rotating speeds with digital display. This allows the setting of the optimum speed for each individual preparation process.

When the number of specimens to be prepared increases, FORCIPOL instruments can be fitted with FORCIMAT automatic head for automation. FORCIMAT automatic head provides high rate of sample preparation and frees the operator from the grinding and polishing procedures.
