ZOTION Launches New F4 Zirconia Sintering Furnace for Dental Laboratories

 

 

Chongqing, China – ZOTION, a manufacturer specializing in dental CAD/CAM equipment and materials, has officially introduced its new F4 Zirconia Sintering Furnace. Designed around the daily production needs of dental laboratories, the F4 delivers improvements in temperature stability, heat distribution, energy efficiency, and ease of operation, offering a dependable solution for the sintering of zirconia crowns, bridges, and other restorations.

Integrated Display System for Stable Operation

The F4 features an integrated display and control design that helps reduce signal interference during operation. Even during long production cycles, the system maintains stable performance without lagging, data drift, or unexpected interruptions. This contributes to greater consistency between batches and helps reduce remakes and material waste, making the furnace suitable for routine laboratory production.

Four MoSi₂ Heating Elements for Better Heat Retention

The furnace chamber is equipped with four molybdenum disilicide (MoSi₂) heating elements combined with an upgraded insulation structure. Heat retention is improved, heat loss is reduced, and energy utilization becomes more efficient.

With a rated power of 2000W, the F4 offers lower operating costs during long-term use, helping laboratories manage energy consumption more effectively.

360° Heating Chamber for Uniform Temperature Distribution

The newly designed 360° three-dimensional heating field provides even temperature distribution throughout the chamber. Temperature accuracy reaches ±1°C, helping every restoration receive consistent heat exposure.

Whether processing a few single crowns or a full batch of multi-unit bridges across all three trays, restorations can achieve uniform density, consistent color, and stable mechanical properties. Uneven heating issues commonly found in traditional furnaces are significantly reduced.

DC Heating Technology with Gentle Temperature Rise

The F4 uses a DC heating system with an adjustable heating rate from 5°C/min to 15°C/min.

The gradual heating process allows zirconia restorations additional time to release internal stress during sintering. This helps reduce the possibility of cracking, distortion, or structural defects, particularly when processing thin restorations, large-span bridges, or highly esthetic zirconia materials.

Practical Specifications for Daily Production

Power Supply: AC220V ±10%

Rated Power: 2000W

Temperature Accuracy: ±1°C

Maximum Heating Rate: 15°C/min

Chamber Size: 120 × 135 × 120 mm

Tray System: Three-layer sintering tray design

Machine Dimensions: 556 × 360 × 647 mm

The compact footprint makes installation easy in small and medium-sized dental laboratories while still providing sufficient chamber capacity for batch production.

Designed for Zirconia Sintering

The F4 is developed specifically for zirconia restorations and supports a wide range of mainstream zirconia materials and sintering programs. Laboratories can select different sintering curves according to material requirements and production preferences.

As a new addition to the ZOTION furnace lineup, the F4 Zirconia Sintering Furnace combines stable performance, precise temperature control, efficient energy use, and user-friendly operation in one compact system. It is well suited for both small-scale custom work and high-volume daily production, providing dental laboratories with a practical and cost-effective zirconia sintering solution.
