This 2500℃ high-temperature vacuum sintering furnace is a
batch-type induction heating unit fitted with IGBT power control,
cutting energy consumption significantly while delivering unrivaled
operational stability. Engineered for precise, efficient material
processing, it combines advanced electric induction heating
technology with a fully sealed vacuum chamber—eliminating external
environmental disruptions to maintain steady, consistent high
temperatures that satisfy the strict sintering criteria of
high-performance materials.
Built with industrial-grade durability, its rugged,
anti-deformation structure is paired with a high-precision
intelligent temperature control system. This setup ensures
accurate, stable regulation of heating rates, holding times, and
cooling procedures, preventing temperature fluctuations and
guaranteeing uniform heating of every workpiece during the entire
sintering process.
Ideal for large-scale or small-batch production, it reliably
processes diverse components including boron carbide plates,
ceramic parts, and alloy pieces. Its user-friendly operation
interface and comprehensive safety mechanisms (over-temperature
alarm, vacuum leakage detection) further ensure stable, continuous
operation—making it perfectly suited for both laboratory R&D
and industrial manufacturing scenarios where processing consistency
is critical.
Application:
Ceramic Materials: Sintering of boron carbide plates, silicon carbide, zirconia,
sapphire, and other advanced ceramic components.
Hard Alloys & Metals: Processing of tungsten carbide, carbide alloys, metal billets,
and powder metallurgy products (e.g., neodymium magnets, NdFe14B).
Special Materials: Sintering of gemstone, diamond, rhenium materials, boron
nitrogen, vanadium carbide powder, and composite metal powders.
