PLC Controlled Dip Coating Machine for Programmable Thin Film Deposition

Product Overview

This PLC-controlled dip coating machine is designed for vertical immersion and withdrawal coating of samples in liquid-phase thin-film materials. A precision lifting wire lowers the sample into the coating solution, holds it for a defined period, and withdraws it at a controlled speed. The process enables a thin film of controlled thickness to form on the sample surface through repeatable immersion, withdrawal, and drying cycles.

The equipment provides programmable control over withdrawal speed, immersion time, entry speed, cycle count, and drying time. Its compact footprint supports efficient laboratory use where bench space is limited, while the straightforward operating method helps new users establish reliable coating procedures quickly. An optional constant-temperature drying oven can be configured when film growth must proceed under controlled thermal conditions.

Designed for laboratory environments, this unit combines a high-precision stepper motor, suspended motor vibration reduction, touchscreen operation, and CE certification. The robust operating range, controlled motion, convenient cleaning, and low power demand make it suitable for repeated research work under demanding academic, institutional, and industrial laboratory conditions.

Key Features

• PLC Program Control: The PLC-based control system allows users to set and adjust withdrawal speed, immersion duration, entry speed, drying time, and the number of immersion and withdrawal cycles. This supports consistent process execution across repeated samples.

• Wide Withdrawal Speed Range: Adjustable withdrawal speed from 1 mm/min to 200 mm/min provides practical control over coating behavior and film formation conditions for different liquid-phase materials and sample requirements.

• Programmable Immersion and Drying: Immersion and drying times can be configured from 1 to 999 seconds. Defined timing helps maintain a repeatable coating sequence and reduces variation caused by manual operation.

• Controlled Multi-Cycle Processing: The system supports 1 to 20 lifting cycles, allowing users to establish repeated coating routines without manually restarting each movement. This is useful when multilayer or repeated deposition procedures are required.

• High-Precision Stepper Motor: The precision stepper motor provides controlled vertical movement and supports accurate, repeatable sample positioning during immersion and withdrawal.

• Vibration-Reduction Design: A suspended motor arrangement helps reduce vibration during operation. Stable movement is important when coating quality depends on uniform sample withdrawal and controlled liquid-film interaction.

• Color Touchscreen Interface: The color touchscreen simplifies parameter entry and adjustment. Operators can configure process settings directly at the machine, supporting efficient setup for both experienced researchers and first-time users.

• Compact Laboratory Construction: Measuring 320 mm x 260 mm x 560 mm, the equipment occupies limited bench space while providing the required vertical travel and sample handling capability. Its compact design is well suited to laboratories with constrained working areas.

• Convenient Maintenance: The simple structure and accessible working arrangement make routine cleaning easier after coating operations. This helps laboratories maintain an orderly workspace and prepare the unit for subsequent experiments.

• Certified and Low-Power Operation: CE certification supports use in professional laboratory environments, while the 50 W power rating helps keep routine operating demand low. The equipment requires no water, compressed gas, or dedicated ventilation installation.

Applications

Technical Specifications

The installation environment should remain within the specified altitude, temperature, and humidity conditions to support stable operation. The unit requires an AC 220 V, 50 Hz electrical connection with reliable grounding. No water, gas, or dedicated ventilation system is needed, which simplifies placement in university, research institute, and enterprise laboratories.

The working table should provide at least 800 mm x 600 mm x 700 mm of available space and support more than 200 kg. These requirements provide a stable foundation for the 17 kg equipment and associated sample-handling activities. Before installation, users should confirm that the table is level, sufficiently rigid, and positioned to give the operator clear access to the touchscreen and coating area.

The motion system accepts a maximum lifting load of 100 g and is designed for samples measuring 75 mm x 25 mm x 2.5 mm. The effective immersion length is 60 mm. Users can set the movement and timing parameters according to the coating material, sample geometry, and research protocol, provided the selected setup remains within the stated load, dimension, and travel limits.

For processes that require thermal stability during film formation, the optional constant-temperature drying oven provides an expanded configuration path. This option allows the drying stage to be performed under a controlled temperature condition when that requirement is part of the experimental method. The base unit remains suitable for standard programmed immersion, withdrawal, and drying-time studies without requiring the optional oven.
