Manufacturing Process of 4D Multi Layer Zirconia Disc
Each Honchon® zirconia disc is the result of a meticulous multi-stage production process, ensuring precision, durability, and consistency.
Powder Loading
High-purity zirconia powder, specifically formulated for dental applications, is carefully loaded into the equipment. Only premium-quality powder is used to ensure stability and safety.
Pre-Pressing (Shaping)
The powder is compressed into a preliminary shape to ensure uniformity and optimal compaction, preparing it for densification.
Cold Isostatic Pressing
The shaped powder is placed into a mold and pressed from all directions using cold isostatic pressure. This step ensures maximum material density and homogeneity.
Pre-Sintering
The discs are heated at controlled temperatures to partially fuse the zirconia particles. This increases strength and makes them ready for machining.
Milling & Shaping
The pre-sintered blanks are precisely milled using advanced CAD/CAM technology to achieve accurate contours and dimensions.
Inspection & Packaging
Each disc undergoes thorough quality control to ensure consistency in shade, shape, and performance. After inspection, they are securely packaged to prevent damage during transportation.
