Gear metering pumps are widely used in coating machines in different industries as follows:

Coating of Optical Films: During the production process of optical films, such as polarizing films and brightness enhancement films, it is necessary to accurately coat optical materials onto the base films. Gear metering pumps can precisely control the flow rate and thickness of the coating liquid, ensuring that the optical properties of the optical films are uniform, thus meeting the strict requirements of high-end electronic products such as liquid crystal displays and organic light-emitting diode displays for optical films.

Encapsulation of Electronic Components: For the encapsulation of electronic components, such as chip encapsulation and circuit board coating, high-precision coating processes are required to ensure the encapsulation quality. Gear metering pumps can accurately deliver encapsulation materials, such as epoxy resins, ensuring the thickness and uniformity of the encapsulation layer and improving the reliability and performance of electronic components.

Coating of Automotive Interior Parts: The surfaces of automotive interior parts, such as seats and instrument panels, often need to be coated with a layer of coating with properties such as wear resistance, weather resistance, and flame retardancy. Gear metering pumps can accurately coat the coating on the surfaces of interior parts with complex shapes, ensuring the quality and performance of the coating and enhancing the aesthetics and service life of the interior.

Bonding of Automotive Windshields: During the installation process of automotive windshields, adhesives such as hot-melt adhesives are needed for bonding. Gear metering pumps can precisely control the coating amount of the adhesives, ensuring the firm bonding between the windshield and the vehicle body while avoiding quality problems caused by excessive or insufficient amounts of adhesives.

Coating of Food Packaging: Food packaging materials, such as paper and plastic films, often need to be coated with a layer of coating with functions such as moisture resistance, oil resistance, and freshness preservation. Gear metering pumps can accurately coat food-grade coatings on packaging materials, ensuring the uniformity and quality of the coating, prolonging the shelf life of food, and ensuring food safety at the same time.

Coating of Labels: During the production process of labels, it is necessary to coat materials such as glue or ink on paper or plastic films. Gear metering pumps can precisely control the coating amount, making the pasting performance and printing effect of labels reach the best, improving the quality and use effect of labels.

Coating of Pharmaceutical Packaging: Pharmaceutical packaging materials, such as aluminum foil and plastic bottles, need to be coated with a layer of coating with functions such as sealing, moisture resistance, and oxidation resistance. Gear metering pumps can accurately coat pharmaceutical coatings on packaging materials, ensuring the quality and stability of pharmaceuticals and prolonging the shelf life of pharmaceuticals.

Coating of Medical Devices: The surfaces of medical devices, such as surgical instruments and implants, often need to be coated with a layer of coating with properties such as antibacterial, lubricating, and biocompatibility. Gear metering pumps can precisely control the thickness and uniformity of the coating, improving the performance and safety of medical devices.

Coating of Paper: During the production process of paper, in order to improve the surface properties of paper, such as glossiness, smoothness, and printability, coating processing is required. Gear metering pumps can accurately coat coatings on the surface of paper, control the coating amount and coating thickness according to different paper uses and quality requirements, and produce various high-quality coated papers, such as coated art paper and whiteboard paper.

Delivery of Pulp Additives: During the preparation process of pulp, various additives, such as sizing agents, strengthening agents, and defoaming agents, need to be added. Gear metering pumps can accurately deliver these additives into the pulp, ensuring the uniform dispersion of additives and improving the performance and quality of paper.

Coating of Plastic Films: Plastic films, such as polyethylene films and polypropylene films, often need to be coated with a layer of functional coatings, such as moisture-resistant, barrier, and antistatic coatings. Gear metering pumps can accurately coat coatings on the surfaces of plastic films, ensuring the uniformity and quality of the coating and expanding the application fields of plastic films.

Lamination of Plastic Films: During the lamination process of plastic films, adhesives such as glue are needed to bond different layers of films together. Gear metering pumps can precisely control the coating amount of the adhesives, ensuring the firm bonding between the films and improving the performance and quality of the laminated films.
