Advanced Vacuum Processing for Rare Earth Permanent Magnets
The rapid growth of electric vehicles, renewable energy systems, robotics, aerospace, defence and advanced industrial applications is driving demand for high-performance Rare Earth Permanent Magnets. Lakshmi Vacuum Technologies Pvt. Ltd. is at the forefront of vacuum processing technology for Rare Earth Permanent Magnet manufacturing in India — with established expertise in developing and manufacturing advanced vacuum processing equipment for this strategic industry.
Vacuum Strip Casting Furnace
The production of high-performance NdFeB magnets begins with the preparation of a homogeneous NdFeB alloy and its conversion into a controlled microstructure suitable for subsequent powder processing. Our Vacuum Strip Casting Furnace is designed for controlled melting and rapid strip casting of Rare Earth alloy compositions.
- High-purity vacuum / inert atmosphere processing
- Controlled melting of NdFeB alloy
- Precise alloy composition and temperature control
- Rapid solidification through strip casting
- Uniform strip thickness and microstructure
- Reduced oxidation and contamination
- Controlled conditions for hydrogen decrepitation & powder preparation
Vacuum Sintering Furnace
Following powder preparation, alignment and compaction, sintering is one of the most critical stages in the manufacture of NdFeB permanent magnets. Our Vacuum Sintering Furnace is designed specifically for controlled thermal processing of compacted Rare Earth magnet components.
- High-temperature operation under high vacuum / inert atmosphere
- Precise temperature control and uniformity
- Programmable heating and cooling cycles
- Controlled vacuum and partial-pressure atmosphere
- Low-contamination processing environment
- High process repeatability
- Controlled sintering and densification
- Multi-stage thermal processing capability
- Data acquisition & process monitoring for traceability
