1. Overview of Equipment and Application Fields

The PF400 standard coating machine is a high-precision multifunctional coating equipment specifically designed for material science research, product quality testing, and small-batch prototyping. This device integrates two core coating processes—precision blade coating and wire rod coating—capable of meeting extensive coating requirements ranging from low-viscosity solvent-based coatings to high-viscosity pastes (such as lithium battery electrode pastes, ceramic precursors, and conductive silver pastes). The PF400 employs a high-rigidity gantry structure and precision guide rail transmission system to ensure the coating head operates without vibration or deviation, achieving optimal film thickness uniformity. Its core features an intelligent digital control system that supports stepless speed adjustment from 0.1mm/s to 50mm/s with exceptional stability. The working platform is equipped with powerful vacuum adsorption and a precision heating system (operating from room temperature to 200°C), enabling secure fixation of various flexible or rigid substrates (e.g., PET film, copper foil, aluminum foil, glass, silicon wafers) while optimizing solvent evaporation rates and film quality through temperature control. Widely applied in R&D and testing for new energy batteries (lithium batteries, fuel cells), photovoltaic industries (perovskite, organic PV), printed electronics, functional ceramics, biomedical coatings, and optical films, the PF400 serves as an essential tool for university laboratories, corporate R&D centers, and quality inspection departments.

2. Core Functional Highlights

· Dual-mode coating system, flexibly adaptable to various processes

o Precision刮刀涂布: Equipped with a high-precision fine-tuning scraper frame that supports micron-level gap adjustment. Users can precisely set the distance between the scraper and substrate according to target film thickness, suitable for high-viscosity slurries and applications requiring extremely precise thickness control. The scraper material is available in stainless steel or wear-resistant polymer materials, resistant to solvent corrosion.

o Mayer Bar Coating: Compatible with standard Mayer Bar installation interfaces, this system enables rapid coating of different wet film thicknesses by replacing with rods of varying diameters. The process is simple and highly reproducible, making it particularly suitable for rapid screening and comparative testing of low-viscosity coatings.

o Rapid switching design: The scraper assembly and wire rod holder feature a modular quick-release design, enabling users to switch between two coating modes within minutes, significantly enhancing experimental efficiency.

· High Precision Drive and Stable Operation

o Wide-range stepless speed control: Powered by high-performance servo or stepper motors, the coating speed ranges from 0.1mm/s to 50mm/s. It operates smoothly without crawling at low speeds, while delivering rapid acceleration and precise positioning at high speeds, meeting the coating process requirements of materials with diverse rheological properties.

o Constant speed control: The system features an integrated closed-loop feedback control system that continuously monitors and adjusts the operating speed, maintaining speed fluctuations within ±1% throughout the coating process to ensure consistent film thickness.

o Long-stroke precision guide rail: The coating head moves along a high-precision straight guide rail, effectively eliminating lateral wobble and vertical jump, ensuring uniform lateral thickness of the coating.

· Intelligent Heating and Vacuum Adsorption Platform

o Wide-area heating function: The workbench is integrated with high-quality heating elements, with a temperature control range from room temperature to 200°C and a precision of ±1°C. The heating function helps reduce the fluidity of high-viscosity materials, accelerate solvent evaporation, or induce specific crystallization processes, significantly improving film formation quality.

o High-Force Vacuum Adhesion: The platform surface is equipped with precision micropores that connect to a high-power vacuum pump, generating strong adhesive force. Whether for flexible films prone to curling (e.g., PI, PET) or smooth rigid substrates (e.g., glass, metal foil), the material can be firmly and evenly adhered to the platform surface, completely eliminating wrinkling, displacement, or bubble formation during the coating process.

o Exceptional thermal uniformity: The heating panel undergoes specialized processing to minimize surface temperature variation (±2% at 100°C), ensuring even substrate heating and preventing coating defects caused by localized temperature differences.

· Humanized Operation and Safety Design

o Intuitive control panel: Featuring a clear digital display and intuitive buttons/rotary knobs, users can easily adjust parameters such as coating speed, stroke length, and heating temperature, with real-time operational status display.

o Adjustable travel protection: Users can customize the start and end positions of coating to avoid wasting materials or damaging equipment due to invalid travel. It has a limit protection function to prevent mechanical overtravel.

o Corrosion-resistant structure: The main body of the equipment and components in contact with chemicals are made of solvent-resistant and acid/alkali-resistant materials (e.g., anodized aluminum, stainless steel, Teflon-coated materials), which are easy to clean and maintain, and adaptable to various harsh chemical environments.

o Emergency stop mechanism: There is an obvious emergency stop button, which can immediately cut off the power supply in case of abnormal situation to ensure the safety of personnel and equipment.
