Micrometer Adjustable Slot Die Applicator for Lab Film Coating

Micrometer Adjustable Lab Slot Die Film Applicators and Coating Heads

Product Overview

The TOB-JTM100 micrometer adjustable slot die applicator is a high-precision coating tool designed for laboratory-scale thin film coating and process development. It is specifically engineered to meet the requirements of advanced coating research where accuracy, repeatability, and environmental stability are critical.

This applicator supports both slot die coating and doctor blade coating, allowing researchers to switch between open and closed coating methods within the same platform. When operating in slot die mode, the slurry flows through a closed cavity, significantly reducing environmental interference and improving coating uniformity.

The system is typically used together with a flat coating machine and a precision slurry feeding device (such as a syringe pump), and is widely applied in battery materials, OLED devices, solar photovoltaic films, and conductive polymer coatings.

What is a Slot Die Applicator?

A slot die applicator is a precision coating device used to deposit uniform thin films onto flat substrates. Unlike traditional adjustable film applicators, slot die coating uses a closed-channel design to control slurry flow, enabling highly consistent coating thickness and improved process stability.

Compared with conventional adjustable film applicators, slot die systems are less affected by environmental factors such as airflow and solvent evaporation, making them ideal for high-precision laboratory coating applications.

Technical Specifications

The TOB-JTM100 slot die applicator is designed for high-precision laboratory coating applications with micrometer-level adjustment.

Core Features and Advantages

● Micrometer-Level Adjustable Coating Control

The applicator is equipped with a digital micrometer adjustment system with 1μm resolution, allowing precise control of coating thickness and gap height. This ensures excellent repeatability and accuracy in thin film preparation.

● Dual Coating Modes (Slot Die & Doctor Blade)

The TOB-JTM100 integrates two coating methods:

- Slot die coating for high-uniformity, closed-system coating
- Doctor blade coating for flexible and rapid testing
This dual functionality makes it ideal for comparative studies and process optimization.

● Closed Coating System for Higher Stability

In slot die mode, the coating process occurs within a sealed cavity, minimizing the impact of environmental variables and improving coating consistency.

● High-Quality SUS630 Material

- The coating head is made of SUS630 stainless steel, providing:
- Excellent corrosion resistance
- Long service life
- Stable mechanical performance under various slurry conditions
- Compact and Laboratory-Friendly Design

The compact structure allows easy integration into laboratory setups, including glovebox environments. The optimized geometric design ensures convenient operation and cleaning.
