Bottom Loading Furnace

What is BLF(Bottom Loading Furnace)?

As the name suggests, material loading in the BLF is done from the bottom side. It means that the door is fitted at the bottom, which is lifted or lowered with a smooth motor drive mechanism. Loading of material is done on the door itself (loading platform).

Why BLF is used?

Heating elements are fitted on all four sides of the inner chamber thus providing the most uniform heat distribution. Loading and unloading of material is easy with help of a lifting platform. Bottom-loading furnaces are ideal for achieving a wide range of heating-cooling cycles while maintaining temperature uniformity and product quality. BLF is convenient for heavy, large, or high-volume workloads.


Working of BLF

BLF uses electrically operated motor gear assembly to raise and lower the loading platform with precision. Loading and unloading time is kept minimum while avoiding any impact.

Application of BLF

Melting Sintering Ceramic injection molding(CIM) Calcining
Soldering Degassing Metal injection molding(MIM) Brazing
Drying Debinding Rapid prototyping Hardening
Tempering Synthesis siliconization Quenching
sublimation Firing Carbonization pyrolysis
Annealing Thermistors Ferroelectric application capacitors
