Dental Sintering Lifting Furnace TT-LF-120-1700 (also known as a denture crystallization furnace) features high-purity silicon molybdenum rods rated for 1800°C, ensuring clean, contaminant-free crystallization and sintering of zirconia dental crowns. It delivers a highly uniform temperature field and includes a convenient bottom-loading design with an automatic lifting mechanism for easy loading and unloading. This furnace is ideal for use in dental laboratories and clinics for the precision processing of zirconia crowns.
- Integrated 7-inch touchscreen menu system with real-time process curve display. Data can be exported, and up to 15 pre-set sintering programs from various zirconia block brands can be stored and accessed anytime. Each program supports up to 30 editable segments.
- Lined with high-purity alumina ceramic fiber for clean, contamination-free operation, with an iron content of ≤440 ppm.
- Equipped with pure U-shaped silicon-molybdenum rods as heating elements, ensuring clean firing of individual zirconia crowns without contamination and supporting fast sintering cycles.
- Cylindrical furnace structure with ring-shaped heating for a highly uniform temperature field, enhancing crown translucency and consistency.
- Features an automatic bottom-loading design with a precision screw system and high-accuracy linear sliders, offering smooth, stable, and shake-free vertical movement.
- Supports two φ100mm sintering trays simultaneously, accommodating approximately 25–50 zirconia crowns per batch for efficient high-volume output.
- Built with a modular safety system that includes audio and visual alarms for over-temperature, overload, and thermocouple failure, along with automatic protective shutdown functions.
