Zhonghuan Electric Furnace Announces Patent for “An Integrated 3D Printing Ceramic Degreasing and Sintering Furnace and Its Operating Method”
2026-01-05
According to the Tianyancha app, Tianjin Zhonghuan Electric Furnace Co., Ltd. recently had its patent application for “An Integrated Furnace for Debinding and Sintering of 3D-Printed Ceramic Shaped Parts and Its Operating Method” published. The abstract states that the invention discloses an integrated furnace for debinding and sintering of 3D-printed ceramic shaped parts, along with a corresponding operating method. The integrated furnace comprises a furnace body, a supporting structure, a lifting drive mechanism, a sealing assembly, and an atmosphere-supply pipeline. The sealing assembly consists of a movable sealing unit and a sealing pipe, which, through vertical movement, can create a sealed chamber within the furnace. The operating method includes the steps of loading, forming a sealed chamber, purging the atmosphere, debinding, decarburizing, sintering, and cooling, thereby achieving fully integrated, continuous processing throughout the entire workflow. By employing dynamic sealing technology, the invention eliminates damage caused by handling green bodies during transfer, significantly improves yield and production efficiency, reduces equipment investment and energy consumption, and resolves the core challenges inherent in conventional step-by-step processing.
The ceramic 3D printing debinding-and-sintering integrated furnace combines the two core processes of “debinding” and “high-temperature sintering” to deliver end-to-end thermal processing—from green body to finished product—specifically designed to address the pain points of conventional manufacturing. Featuring an all-in-one design, the equipment completes both debinding and sintering in a single chamber without the need to transfer the green body, effectively preventing cracking, deformation, and contamination during handling. The furnace shell is constructed from high-grade, high-temperature-resistant materials with exceptional thermal insulation, paired with an advanced heating and temperature-control system that precisely meets the thermal-processing requirements of various ceramic materials, including zirconia, alumina, silicon nitride, and ceramic slurries, thereby providing stable and reliable forming assurance for 3D-printed ceramic components.
