Advanced Vacuum Sintering Furnaces

Lakshmi Vacuum Technologies manufactures high-temperature vacuum sintering furnaces engineered for the densification of powder materials. Our furnaces are critical for powder metallurgy, ceramics, and advanced composite manufacturing, providing contamination-free environments for structural transformation.

By operating under high vacuum or controlled atmospheres (like Argon), our sintering furnaces prevent oxidation and remove impurities, allowing metal and ceramic powders to bond at the molecular level. This process creates exceptionally strong, high-density components with precise metallurgical properties.

Capable of reaching temperatures up to 2000°C, our systems feature advanced graphite hot zones and precise PLC/SCADA control systems. This ensures absolute temperature uniformity and repeatability, batch after batch, for your most demanding sintering applications.

FAQs

Frequently Asked Questions

What is vacuum sintering used for?

Vacuum sintering densifies metal and ceramic powders by heating them below melting point in a controlled atmosphere. It is used for carbide tools, powder metallurgy parts, MIM components, ceramics and other high-performance materials that must stay contamination-free.

What maximum temperature do your sintering furnaces reach?

Our systems are offered with working temperatures from 1250°C up to 2000°C, with graphite hot zones designed for sustained high-temperature cycles. The right configuration depends on your material and process.

What vacuum level and atmosphere do you support?

Standard systems run at 1 x 10-2 mbar with 10-6 mbar available if required, and support vacuum or argon atmospheres to suit the material being processed.

What size and load capacity are available?

A typical system offers a 900 x 900 x 1200 mm useful working area and 900 kg charge weight, and we customise the working area, hot zone and quench pressures to your exact process.

Do your sintering furnaces support gas quenching?

Yes. Quenching pressures of 6, 10, 12 or 15 bar can be specified depending on the material and cooling rate your process requires.

Can we run trials or send parts before buying?

Yes. The group runs nine vacuum heat treatment units across India, so trials, job work and pilot batches can be arranged alongside your furnace selection process.
