Vim®-1 Vacuum Cold Mounting Machine

Product Introduction
The Vim®-1 Vacuum Cold Mounting Machine is designed for vacuum impregnation and cold mounting of metallographic specimens, particularly porous, fragile or complex samples. By removing trapped air from the specimen, the mounting compound can penetrate pores and gaps more effectively, reducing voids between the specimen and mounting material.
This improves edge retention and specimen support during subsequent grinding and polishing, making the Vim-1 especially useful for fragile and porous materials.
A robust vacuum pump provides sufficient vacuum for rapid air removal. The unique rotating cup holder inside the vacuum chamber allows multiple specimens to be vacuum impregnated simultaneously. The dedicated pouring mechanism enables premixed mounting compound to be placed in a mixing cup and poured into specimen molds in a controlled manner.
The system is compatible with various epoxy resin and polyester cold-mounting compounds.

Performance Features
• Designed for vacuum cold mounting and vacuum impregnation of metallographic specimens.
• Removes trapped air from porous and permeable samples.
• Improves penetration of epoxy or polyester mounting compounds.
• Reduces gaps between the specimen and mounting compound.
• Helps improve edge retention during grinding and polishing.
• Provides better support for fragile specimens.
• Robust vacuum pump provides a maximum vacuum of -85 kPa.
• Rotating cup holder supports simultaneous processing of multiple specimens.
• 5 rpm rotating tray helps distribute mounting compound during impregnation.
• Dedicated pouring mechanism simplifies resin filling.
• Compatible with various epoxy resin and polyester cold-mounting compounds.
• Compact vacuum chamber with Φ260 × 125 mm chamber dimensions.
• Simple vacuum/pressure cycling operation.

Working Principle
The specimen mold is placed inside the vacuum chamber, and the prepared cold-mounting compound is placed in the mixing cup. After the chamber is evacuated, air trapped inside pores and cavities of the specimen is removed.
The premixed mounting compound is then poured into the specimen mold. Under vacuum conditions, the compound can penetrate the previously evacuated pores and gaps, improving contact between the mounting material and specimen.
After approximately one minute of pouring/holding, the chamber is returned to atmospheric pressure. The vacuum-pressure cycle can be repeated several times to improve impregnation. The chamber is then opened and the mounted specimen is allowed to cure normally.
This process is particularly beneficial for porous, cracked, fragile or edge-sensitive specimens.

Application Scenarios
The Vim®-1 is suitable for metallographic and material sample preparation where porous or fragile specimens require enhanced mounting support:
• Metallographic laboratories
• Materials research
• Porous metal specimens
• Rock and geological specimens

Comparison: Vim-1 Vacuum Cold Mounting vs. Conventional Cold Mounting

Feature	Vim®-1 Vacuum Cold Mounting	Conventional Cold Mounting
Air Removal	Vacuum removes trapped air	Air may remain in pores
Resin Penetration	Improved by vacuum impregnation	Mainly gravity/manual filling
Porous Samples	Particularly suitable	More difficult to impregnate
Edge Retention	Helps improve edge support	Depends on mounting quality
Fragile Samples	Provides enhanced support	May leave gaps around specimen
Multiple Samples	Rotating cup holder supports multiple samples	Usually manual processing
Mounting Compound	Epoxy and polyester compounds	Depends on mounting method
Process Control	Vacuum/atmospheric pressure cycling	Generally simpler manual process
Application	Advanced metallographic sample preparation	General cold mounting

FAQ
1. What is the Vim®-1 Vacuum Cold Mounting Machine used for?
It is used for vacuum impregnation and cold mounting of metallographic specimens, especially porous and fragile samples.
2. Why is vacuum used during cold mounting?
Vacuum removes air trapped in pores and gaps, allowing the mounting compound to penetrate these areas more effectively.
3. What types of samples benefit most from vacuum impregnation?
Porous, cracked, fragile and complex specimens can particularly benefit because improved resin penetration provides better support during subsequent preparation.
4. What is the maximum vacuum of the Vim-1?
The maximum vacuum is -85 kPa.
5. Can multiple specimens be processed at the same time?
Yes. The vacuum chamber uses a rotating cup holder that allows multiple specimens to undergo vacuum impregnation simultaneously.
6. What mounting compounds can be used?
