- Product Introduction
Products Description
Dental Zirconia Sintering Furnace for CAD/CAM Dental Laboratories
After zirconia is milled, the restoration goes through another important stage of the digital workflow: sintering.
During sintering, the milled zirconia restoration is heated according to a programmed temperature cycle. The process affects the final density and dimensions of the restoration, so heating rate, temperature control, holding time, cooling, and program settings all need to match the zirconia material being used.
At Zotion, we develop and manufacture dental sintering furnaces for zirconia processing in dental laboratories.
features include:
Maximum temperature up to 1650°C
Programmable sintering cycles
Controlled heating and cooling
Touchscreen operation
Temperature accuracy of up to ±1°C
Multiple programmable settings

Why Temperature Control Matters in Zirconia Sintering
During sintering, the restoration follows a programmed temperature curve. The heating rate, target temperature, holding time, and cooling stage are all part of the sintering cycle.
The program needs to match the requirements of the zirconia material being processed.
Zotion provides material-specific sintering recommendations rather than using the same program for every zirconia grade.

Products advantages
Zirconia-Optimized Sintering
Precisely calibrated programs for 3Y, 4Y, and 5Y zirconia ensure optimal strength, translucency, and long-term durability.
High-Speed Performance
With heating rates of up to 100°C/min, the furnace enables rapid sintering cycles. A single crown can be completed in 15–30 minutes, significantly improving productivity.
Precise Temperature Control
An advanced PID control system with accuracy up to ±1°C ensures uniform heating and consistent restoration quality.
Easy and Intelligent Operation
An intuitive touchscreen, multi-language interface, and preset programs simplify operation and reduce training requirements.
Reliable and Safe Design
A durable structure combined with multiple safety protection systems ensures stable long-term operation and low maintenance costs.
Wide Compatibility
Compatible with most zirconia discs and other dental ceramics, suitable for both chairside applications and laboratory production.
What We Check During Furnace Production
As a dental sintering furnace manufacturer, we check the main operating parameters of the furnace during production and final inspection. The exact specifications vary by model.
Heating System
The heating system is checked against the rated heating performance of the furnace.
For example, the F2 model has a maximum heating rate of up to 100°C/min, while slower heating programs can be selected when required by the zirconia material.
The furnace can reach a maximum temperature of 1650°C, which covers the high-temperature range required for dental zirconia sintering.
Temperature Control
Temperature control is checked during the furnace testing process.
For applicable Zotion models, the specified temperature accuracy is up to ±1°C.
The control system follows the programmed heating rate, target temperature, holding time, and cooling stages. This allows the selected sintering cycle to be reproduced according to the programmed parameters.
Insulation
The insulation system is used to limit heat loss from the sintering chamber during operation.
During production inspection, we check the furnace's heating and temperature-holding performance rather than evaluating insulation only by its appearance.
Chamber Structure
The chamber size and tray configuration depend on the furnace model.
For example, the F2 is equipped with three trays, allowing technicians to load multiple zirconia restorations in one cycle.
The actual loading capacity depends on the size and arrangement of the restorations rather than simply the number of trays.
Control Software
The control system allows technicians to create, edit, save, and select sintering programs according to the furnace model.
A typical program can include settings such as:
Starting temperature
Heating rate
Target temperature
Holding time
Cooling stage
These parameters are checked during furnace production and final inspection according to the specifications of each model.
How to Choose a Dental Zirconia Sintering Furnace
When customers ask which furnace is suitable for their laboratory, we normally look at several practical factors.
How many restorations do you sinter each day?
This helps determine the chamber capacity and cycle frequency you need.
Do you mainly use conventional or fast sintering?
If your laboratory mainly uses conventional sintering cycles, a standard furnace configuration may be suitable.
If shorter turnaround times are part of your production requirements, a fast-sintering model may be worth considering.
Which zirconia materials do you use?
Check the sintering programs recommended for the zirconia materials you currently use and compare them with the furnace's available program settings.
Do you need multiple programs?
If your laboratory works with several zirconia grades, the ability to save and select different programs can make daily operation easier.
What is your local power supply?
Voltage and frequency should be confirmed before ordering, as power requirements can vary by model and market.

Customer Services
Zotion develops and manufactures dental sintering equipment as part of its CAD/CAM dental product range.
Our engineering team works with zirconia materials, milling equipment, and sintering equipment, giving us experience across the following workflow:
Zirconia Material → Milling → Sintering → Finishing
This is useful when a customer needs technical information that involves more than the furnace itself, such as selecting a suitable sintering program for a Zotion zirconia material.
For product-specific questions, our team can provide the corresponding operating instructions and sintering information.
Support After Installation
After a new furnace is installed, laboratory technicians need to become familiar with its programs, temperature curves, loading methods, maintenance requirements, and basic troubleshooting.
Zotion provides technical support for installation, operation, and questions related to sintering parameters.
For customers using Zotion zirconia, we can also provide the corresponding recommended sintering parameters.

FAQ：
1.What temperature does a dental zirconia sintering furnace need to reach?
Dental zirconia is generally sintered at high temperatures, but the required temperature depends on the zirconia material and its manufacturer's recommended program. Zotion furnaces can reach temperatures up to 1650°C.
2.How long does zirconia take to sinter?
There is no single sintering time for all zirconia materials.
A conventional cycle may take several hours, while some zirconia materials and furnace models support shorter cycles. The Zotion F1 has a specified fast-sintering cycle of around 25 minutes under defined test conditions.
3.Can one furnace sinter different zirconia brands?
In many cases, a furnace can be used with different zirconia brands if its temperature range and programmable settings meet the requirements of the materials. The sintering instructions provided by the zirconia manufacturer should be followed for each material.
4.What is the difference between fast and conventional sintering?
The main difference is the heating and holding schedule.
Fast sintering uses a shorter programmed cycle, while conventional sintering uses a longer temperature curve. Fast sintering should only be used when the zirconia material and restoration are suitable for the selected process.
5.How do I choose the right Zotion furnace?
Tell us your approximate daily production, zirconia materials, preferred sintering cycle, and local power requirements. We can then help you compare the available models and select one that matches your laboratory's requirements.
