Binder removal is a critical step for manufacturers of cast or molded products. Debinding furnaces employ several methods to handle a wide variety of binder materials, including high-temperature polymers used in Metal Injection Molding (MIM) and 3D Printing/Additive Manufacturing. Debinding can be performed under positive pressure or partial pressure atmospheres using flowing argon, nitrogen, hydrogen, or other inert or reactive gases or gas mixtures. These flowing gases sweep binder vapors from the product efficiently.

Advanced control systems provide full recipe control over gas flows, pressures, and flow direction to minimize shadowing effects common in some MIM processes. Differential pressure controls isolate and remove binders effectively without contaminating the hot zone. Burn-off or incinerator systems eliminate binder vapors, while cold traps or two-stage condenser systems capture heavier wax or binder residues to protect vacuum pumps and downstream equipment.
