This furnace is used to sinter compressed powder compacts of metal, ceramic, or cemented carbide into solid, dense components. Operating at high temperatures (e.g., 1200°C), it applies heat to cause atomic diffusion across particle boundaries. The working principle often requires controlled atmospheres (hydrogen, nitrogen, vacuum) to reduce surface oxides and promote bonding. Its purpose is in Powder Metallurgy (PM) manufacturing, producing complex net-shape parts like gears, bearings, and filters with high material utilization and excellent properties for automotive, aerospace, and industrial applications.
This configuration is suitable when the sample load must fit a 390 x 390 x 770 MM chamber with usable chamber volume of 117.1 litre, approximate power load of 19.8 kW, square chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes powder metallurgy sintering, ceramic densification and ceramic firing cycles.

Trutherm manufactures 1200 Degree Celsius (°C) Powder Sintering Furnace 390 x 390 x 770 MM Chamber for buyers who search by exact machine type, chamber size and 1200°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
Shrinkage during sintering is predictable but process-dependent, so setter plates and posts are used to support the part and prevent it sticking to the chamber floor as it densifies.
Dental, technical-ceramic and powder-metallurgy sintering each specify tight temperature-uniformity tolerances, which is why sintering furnaces are built with finer zone control than a standard box furnace.
This sintering furnace is tuned for the slow, multi-segment ramp/soak profiles densification needs, giving finer schedule control than a general box furnace where a simple on/off or single-ramp cycle is normally enough.
