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substrate is then withdrawn vertically at a controlled speed.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.
