What Is a Dip Coater?
A Dip Coater is a surface coating system that operates on the principle of immersing a substrate into a coating solution and withdrawing it at controlled speeds and durations. This method is particularly preferred for thin-film coating applications and allows precise control of coating thickness.

Dip Coater systems offer the following advantages:

• High surface uniformity

• Precise control of coating thickness

• Repeatable and standardized results

• Compatibility with a wide range of materials and coating solutions

These features make Dip Coater systems indispensable for R&D, laboratory, and industrial applications.

DMR Tekno’s Dip Coater Approach
DMR Tekno adopts a process-oriented engineering approach in Dip Coater projects. Each application differs in coating solution, viscosity, target film thickness, and production capacity. Therefore, instead of standard solutions, fully project-specific systems are designed.

DMR Tekno’s Dip Coater approach is based on the following core principles:

• Precise and repeatable coating

• Stable mechanical structure

• Advanced automation and control

• Ease of use and maintenance

• Long-lasting and reliable system design

Thanks to this approach, the Dip Coater systems developed by DMR Tekno are used safely across various industries.

Working Principle of the Dip Coater
The working principle of Dip Coater systems is relatively simple, yet it requires high precision in practice. The coating process mainly consists of three stages:

Immersion:
The substrate is immersed into the coating solution at a defined speed, ensuring complete and uniform contact between the surface and the solution.

Dwell Time:
The substrate remains in the solution for a specified duration. This time directly affects coating thickness and surface interaction.

Withdrawal:
The substrate is withdrawn from the solution at a controlled and constant speed. Withdrawal speed is one of the most critical parameters determining coating thickness.

DMR Tekno Dip Coater systems control these three stages with high precision to achieve excellent results.

Critical Parameters in Dip Coater Design
The success of Dip Coater systems depends on the technical parameters considered during the design phase. DMR Tekno analyzes these parameters in detail for each project.

Immersion and Withdrawal Speed
One of the most important factors directly affecting coating thickness. Controlled by precision motors and drive systems.

Coating Solution Properties
Viscosity, density, and chemical composition form the basis of the design.

Substrate Size and Weight
The dimensions of the part to be coated influence the carrier mechanism and frame design.

Environmental Conditions
Factors such as temperature, humidity, and vibration can directly affect coating quality.

Mechanical Structure and Stability
Mechanical stability is critical for coating quality in Dip Coater systems. Vibrations or mechanical oscillations may cause waviness and irregularities on the coated surface.

In DMR Tekno Dip Coater systems:

• High-rigidity frame design

• Precision linear motion systems

• Low-vibration motors and transmission components

are used to create a stable and reliable structure.

Coating Bath and Material Selection
Since the coating bath is in direct contact with the coating solution, chemical resistance is of great importance. DMR Tekno offers different material options depending on the application.

Available bath materials:

• Stainless steel

• Glass

• Teflon and special polymers

This variety allows the safe use of different chemical coating solutions.

Automation and Control Systems
DMR Tekno Dip Coater systems can be equipped with advanced automation infrastructures. Thanks to PLC- or microcontroller-based control systems, all process parameters can be precisely adjusted.

Advantages provided by automation systems:

• Precise control of immersion and withdrawal speeds

• Timing and recipe management

• Repeatable processes

• Minimization of operator errors

Optional data logging and remote monitoring systems can also be integrated.

Energy Efficiency
Dip Coater systems are processes that operate with low energy consumption. DMR Tekno prevents unnecessary energy losses by optimizing motor and drive selections.

Energy efficiency approach:

• Proper motor selection

• Optimized motion profiles

• Low-friction mechanical design

This approach reduces operating costs while contributing to environmental sustainability.
