Product Introduction
The temperature-controlled dip-coating machine is designed for coating processes that require specific temperature conditions during the dip-and-withdraw cycle. A clean, dry substrate is immersed in a solution (or sol); based on preset parameters, the substrate is then withdrawn vertically at a controlled speed. This process deposits a "wet gel film" onto the substrate. As the solvent evaporates from the wet gel film, the layer solidifies into a "dry gel film." Subsequent drying and high-temperature heat treatment transform this into the desired nanomaterial thin film.
Key parameters—such as constant temperature, withdrawal speed, withdrawal height, immersion time, number of coating cycles (for multi-layer coating), and interval time between coatings—are all continuously adjustable and precisely controlled. There are no special requirements for the substrate material; the system accommodates various shapes, including sheets, blocks, and cylinders. Stable operation and vibration-free liquid surfaces during the process significantly enhance experimental accuracy and efficiency.
Suitable for coating processes on solid materials such as silicon wafers, glass, ceramics, and metals; applicable to both scientific research and industrial production.
Product Features: Temperature-Controlled Dip-Coating Machine
1. Precision vertical withdrawal mechanism. Features a newly upgraded, German-imported vertical withdrawal assembly made from specialized functional materials. It offers high precision, zero-backlash transmission, smooth operation, corrosion resistance, a maintenance-free lifespan, and exceptional durability.
2. Servo motor drive. Paired with the German-imported withdrawal assembly and a programmable control system, the drive ensures operational precision and stability. The servo motor’s high precision, smoothness, and vibration-free operation offer performance unmatched by stepper motors.
3. Fully automated, multi-parameter program control. The system allows for the precise control and continuous adjustment of six parameters: descent speed, immersion time, withdrawal speed, coating length, number of coating cycles, and interval time between coatings. Once the coating program is set, the entire process—from lowering and immersion to the actual dip-coating (withdrawal)—runs fully automatically.
4. The coating system features a 7-inch LCD touchscreen for convenient control; operating parameters are displayed in real-time, providing an intuitive view of the coating progress.
5. Multi-stage temperature programming is supported, ensuring precise temperature control and high uniformity. The entire coating process takes place within a constant-temperature zone, with the temperature control system featuring an LCD display.
6. Limit sensors are installed at both the top and bottom positions; the mechanism stops automatically upon reaching these limits, preventing over-travel during lifting or lowering operations.
7. Operation is stable, continuous, and smooth at both high and low speeds. There is no vibration at the liquid surface during coating, resulting in a more uniform film.
8. A specially designed flat-jaw clamp grips the sample evenly from both sides without causing damage.
