Product Introduction
This series of graphite debinding and sintering integrated furnaces is specially designed by our company for metal powder injection molding (MIM), powder metallurgy, and binder jetting3DMetal Printing (Binder Jetting) industry, a vacuum degreasing and sintering integrated equipment, mainly suitable for304Stainless Steel,316Metal materials such as stainless steel and iron-based alloys. The equipment adopts a double-layer water-cooled vacuum shell structure, uses graphite as the heating element, and cooperates with multi-zone independent temperature control technology to achieve excellent temperature uniformity. The degreasing process supports both vacuum degreasing and partial pressure degreasing modes. The gas conveying system adopts a multi-channel laminar flow design, which improves the degreasing and binder removal effect. This equipment is the preferred equipment for the powder metallurgy industry to carry out integrated degreasing and sintering processes.
Technical Features
Integrated degreasing and sintering: Hot degreasing and high-temperature sintering are completed in the same furnace, avoiding contamination or oxidation during workpiece transfer, shortening the production process, and improving efficiency.
Double-layer water-cooled vacuum shell: The outer shell is forced water-cooled, with a low surface temperature; the overall sealed structure can achieve high vacuum, meeting the requirements of stainless steel and iron-based alloys for low oxygen and low nitrogen environments.
Graphite multi-zone independent temperature control: Uses high-purity graphite heating elements, with fast heating speed and high radiation heat transfer efficiency; multi-zone independent control ensures uniform temperature distribution in the furnace, adapting to complex shaped workpieces.
Dual Mode Debinding (Vacuum+Partial Pressure): Vacuum degreasing (rapidly removes binder decomposition gases) or partial pressure degreasing (introduces a small amount of inert gas to assist mass transfer) can be selected, effectively reducing residual carbon and ash content, and preventing carbon increase after sintering.
Multi-channel laminar gas system: Gas flows horizontally across the workpiece surface from multiple inlets, achieving uniform atmosphere distribution and avoiding dead zones, resulting in more thorough binder removal and a purer sintering atmosphere.
Suitable for stainless steel and iron-based alloys: High vacuum and precise atmosphere control can effectively prevent oxidation of elements such as chromium and iron, ensuring the density, hardness, and corrosion resistance of sintered parts.

Product Advantages
Simplified production process: Degreasing and sintering are completed in one step, eliminating intermediate processes and equipment, reducing labor and equipment investment costs, and shortening delivery cycles.
Excellent degreasing effect: Multi-channel laminar flow gas combined with vacuum/Dual pressure mode, binder discharge is cleaner, reducing defects such as residual carbon, blistering, and cracking, thereby improving the yield rate.
High temperature field uniformity: Graphite multi-zone heating design, good consistency in shrinkage rate of batch workpieces during sintering, especially suitable for high loading production.
High Efficiency and Energy Saving: Graphite heating elements have small thermal inertia, allowing for rapid heating and cooling. The furnace body's sealing and insulation design reduces energy consumption, leading to lower costs for mass production.
Good surface quality: Sintered under vacuum or protective atmosphere, the workpiece surface is free of oxidation, bright and clean, and does not require subsequent pickling or sandblasting treatment.
Safe and Reliable: Double-layer water-cooled shell and a complete safety interlock system (over-temperature, water pressure, vacuum, abnormal atmosphere alarms) adapt to continuous industrial production.
Long Equipment Life: Graphite heating elements and hot zone structures are optimized for durability and ease of maintenance. The furnace lining materials also use corrosion-resistant high-purity graphite and carbon fiber composite materials.
