Continuous Mesh Belt Sintering Furnace - 1150°C for Powder Metallurgy, Atmosphere-Protected

Sintering furnaces are precision high-temperature heat treatment industrial furnaces. Through precise temperature control combined with a controlled atmosphere or vacuum-sealed environment, they utilise atomic diffusion to bond powder green parts and reduce porosity at temperatures below the raw material’s melting point, densifying the green parts into finished workpieces. The process prevents oxidation, decarburisation and deformation throughout, making it the core forming equipment following powder compaction.

After being loaded into the furnace, workpieces sequentially undergo three processes: debinding and degreasing → high-temperature sintering → uniform controlled cooling:
Low-temperature stage: Removal of binders and lubricants from the green body;
High-temperature sintering stage: Atomic diffusion forms a sintering neck, causing the green body to shrink and densify;
Slow cooling stage: Uniform cooling under a protective atmosphere to prevent product cracking and oxidation.

1. Vacuum Sintering Furnaces (Batch Type): Cemented carbides, tungsten-molybdenum alloys, neodymium-iron-boron magnets, special ceramics, and small-batch high-precision products.
2. Mesh Belt Continuous Sintering Furnaces: Iron- and copper-based oil-impregnated bearings, small powder parts, and high-volume assembly line production.
3. Pusher-Type Atmosphere Sintering Furnaces: Large structural components and stainless steel powder metallurgy parts.

1. Powder Metallurgy: Automotive gears, sprockets, oil-impregnated bearings, construction machinery structural components.
2. Cemented Carbide: CNC cutting tools, drill bits, wear-resistant moulds.
3. New Electronic Materials: Ferrite cores, aluminium nitride ceramics, lithium battery components.
4. Refractory Metals: Tungsten, molybdenum and titanium alloy products.

1. Precise temperature control: Minimal temperature control error, high sintering consistency of products, and low defect rate.
2. Sealed atmosphere/vacuum design: Isolates the workpieces from air, preventing oxidation and decarburisation.
3. Energy-efficient and environmentally friendly insulated furnace body: Low heat loss, resulting in lower energy consumption during long-term use.
4. Optional automation: Intelligent temperature control system allows one-touch setting of heating and cooling curves for simple operation.
