Small Continuous Laboratory Coating Machine for Precise Wet Film Application

Product Overview

This small continuous laboratory coating machine is designed to produce precise, repeatable wet films on controlled substrates. Manual coating often varies with operator technique, coating speed, and pressure applied to the coating rod, making it difficult to compare samples reliably. This system provides a controlled mechanical coating motion that improves wet-film consistency and reduces variation between operators.

The equipment is suitable for laboratory production trials involving adhesives, paper, films, and related coating materials. Its 30 cm effective coating width and 40 cm coating length support practical sample preparation while maintaining a compact footprint for laboratory benches and pilot-scale development areas. It is useful for coating process development, sample evaluation, formulation comparison, and small-batch production studies across coating and converting applications.

A variable-speed drive allows operators to select a suitable coating rate for the material and substrate under evaluation. The rigid base, glass coating bed, clamping arrangement, and adjustable bed support help maintain stable contact between the substrate and coating rod. With correct installation, cleaning, and alignment, the equipment provides dependable operation for repeated testing under demanding laboratory conditions.

Key Features

• Controlled Continuous Coating Motion: Motorized movement provides a consistent coating stroke, reducing the operator-to-operator differences associated with manual application and improving the repeatability of wet-film samples.

• Adjustable Coating Speed: The drive operates from 0 to 250 cm/min with stepless speed adjustment, allowing users to match the coating rate to adhesive, paper, film, and other process materials. Custom speed configurations can also be requested when a specific development process requires them.

• 30 cm Effective Working Width: The coating area provides a 30 cm effective coating width across a 40 cm coating length. This format supports representative laboratory samples without requiring the space or material consumption of full production equipment.

• Dedicated Coating Rod: The supplied coating rod is 10 mm in diameter and 40 cm long, with a 30 cm effective coating section. Its defined geometry supports controlled contact across the working area.

• Stable Glass Coating Bed: The glass coating bed provides a smooth, level support surface for substrates. Keeping the bed clean and free from debris helps preserve flatness and supports consistent coating results from one test to the next.

• Secure Substrate Clamping: Clips hold the selected substrate firmly on the coating bed. This reduces substrate movement during the coating stroke and improves sample quality, especially when working with thin paper or flexible films.

• Adjustable Bed Parallelism: The coating bed support feet can be adjusted to align the bed parallel with the coating rod. A feeler gauge can be used to check the gap, enabling fine adjustment for more uniform coating contact.

• Practical Sample Handling: The front-mounted coating control supports straightforward testing, while the waste collection tray makes it easier to remove residual material after the coating cycle. Finished samples can be removed promptly for inspection or further testing.

• Compact Laboratory Construction: Measuring 580 x 340 x 180 mm and weighing 20 kg, the unit fits efficiently into laboratory work areas while providing a stable platform for repeatable coating trials.

Applications

Technical Specifications

The equipment should be unpacked at or near its installation location whenever possible. Before opening the package, inspect the external packaging for visible damage. After unpacking, check the condition of the unit and compare the contents with the packing list. Any damage or shortage should be documented and reported in writing immediately.

Before operation, place the machine on a firm, level foundation in an area isolated from vibration. Install the glass coating bed centrally between the two swing arms, ensuring that its rear edge is flush with the rear of the machine. The bed and coating rod must remain parallel. If adjustment is required, use a feeler gauge to identify the gap and place an appropriate shim beneath the relevant support foot. The supports are normally supplied unfixed so that users can adapt the positioning to their specific requirements; they may be bonded after the correct alignment has been established.

For each coating run, place the selected substrate flat on the glass bed and secure it with clips. Return the push rod before installing the coating rod, then select the required speed using the stepless control. Position the required amount of coating material directly in front of the rod and select the TEST position to begin the coating stroke. When the stroke is complete, scrape remaining material into the waste collection tray and remove the finished sample.

Cleaning is important for maintaining coating accuracy. Debris or dried material on the glass bed can change the bed flatness and affect the next coating result. Any spilled material should be removed promptly, and waste should be cleaned after every use. If the main unit does not move, first verify the power supply, switch position, and indicator status. Then check that the speed control is not at its minimum setting and confirm that the coating control is oriented correctly.
