Equipment features:
1. High precision control
Temperature control: PID controller is used to achieve precise temperature control, ensuring temperature stability and gradient consistency during crystal growth process.
Motion control: Precise mechanical system and servo motor drive ensure the smoothness and accuracy of crucible descent, furnace movement, and rotating lifting actions.

2. Optimized temperature gradient
Through carefully designed heating element layout and cooling system, an ideal temperature gradient can be formed within the melt, which is beneficial for defect free growth of single crystals.

3. Uniformity and Quality
Rotating pulling: Rotation helps to achieve uniform distribution of temperature and composition inside the melt, reducing micro defects in the crystal.
Adjustable pulling speed: Adjust the pulling speed according to different material characteristics to obtain the best crystal growth conditions.

4. High degree of automation
Programming control: Supports multi segment temperature curve programming and motion parameter settings, allowing users to easily set and monitor the entire growth process through a touch screen or computer interface.
Data recording and analysis: Built in data acquisition system, real-time recording of key parameters such as temperature, position, and speed, and providing professional data analysis software for subsequent analysis.
