The curtain coating machine draws the liquid paint from the paint box into the precise knife bit and down like a waterfall as the materials pass through the paint curtain on the conveyor at high speed. This type separates the conveyors from the machine body, preventing any shaking that could affect the waterfall coating effect and avoiding waves and uneven coating.
Application Materials:
Application Coatings:
The curtain coating machine creates a continuous sheet of liquid coating through the knife head, allowing flat panels to pass through the coating curtain at a controlled conveying speed. The split structure separates the coating assembly from the conveyor sections, helping maintain coating stability while panels move through the application area.
SENLIAN curtain coating machine is suitable for fiber cement board, magnesium oxide board, calcium silicate board, wood, veneer, glass, metal, plastic, marble, ceramic, and other compatible substrates. UV, PU, and PE coatings can be applied according to different production requirements.
As a continuous curtain coater, the machine provides a controlled coating method for flat surfaces where uniform material distribution and stable film thickness are required.
The independent knife body operates between two separate conveyor sections. Panels enter through the first conveyor, pass beneath the falling coating curtain, and continue onto the discharge conveyor. Separating the coating structure from the conveying system reduces mechanical influence around the knife area and helps maintain a stable coating flow during continuous production.
The mechanical flip-style knife bit allows adjustment through a handwheel and multiple screws. The knife position and coating gap can be adjusted according to coating thickness requirements and material characteristics. The larger paint cavity supports higher coating flow when the production process requires additional material supply.
Coating quality depends on stable material conditions before the coating reaches the knife head. The paint system can be configured with a heating and filtering box or a filtering box according to coating characteristics.
Filtering removes air bubbles and impurities before application, while the low-speed heavy-duty impeller pump maintains a consistent coating supply throughout the process.
The coating system includes:
The aluminum alloy knife body undergoes T6 heat treatment, planishing, and electroplating. The planished surface supports consistent contact across the coating area, while electroplated components improve corrosion resistance during operation.
For a complete finishing route, the curtain coating machine can be positioned after surface treatment equipment and connected with a UV curtain coating line. This arrangement allows panel preparation, curtain application, and curing processes to operate as one continuous production flow.
Different substrates and coating materials may require adjustments to the coating configuration. The curtain coating machine can be customized according to working size, knife head design, paint container, mechanical structure, conveyor layout, and electrical configuration.
The coating section can be arranged around actual panel dimensions, coating characteristics, and production requirements, allowing the machine to integrate into different surface finishing processes.d your actual panel dimensions, coating characteristics and production la
Custom curtain coating machines of different sizes are available for various products, and the parameters will vary accordingly. Please contact us.
When high-quality coatings are combined with curtain coating processes, they can impart excellent surface effects and coating performance to raw materials, resulting in wear resistance, resistance to yellowing, strong adhesion, and a hardness of 2-4H (adjustable depending on the coating type).
The curtain coating machine requires only 1-2 general workers to complete the order that would traditionally require 5-10 professional painters using manual spraying or brushing, significantly increasing daily output, ensuring consistent product quality, and reducing comprehensive production costs.
The curtain coating machine is compatible with various UV and polyurethane coatings, including clear coats, primers, colored paints, and topcoats, meeting the application requirements of industries such as furniture, building materials, electronics, decoration, and automotive, offering high flexibility.
The main knife body uses a mechanical flip-style tool bit rather than a traditional air-cylinder type. Fine manufacturing allows one wheel to adjust the wider curtain coating machine, enabling the paint waterfall to be evenly and easily distributed. More screws on the knife allow more precise adjustment of coating thickness, especially for wide-board coating. A larger knife paint cavity can support greater paint flow.
The aluminium alloy knife body of our curtain coating machine is precision-manufactured with T6 heat treatment, surface planishing, and electroplating. Automatic planishing equipment ensures the knife surface is extremely even, maintaining a consistent paint-coating thickness. The main parts of the knife are electroplated to prevent rusting and ensure long-term operation.
The curtain coating machine comprises three parts: two conveyors and an independent knife body. The conveyors automatically detect the board position and adjust the conveying speed accordingly, while the independent knife body precisely adjusts the knife head height via lifting and lowering mechanisms, or adjusts the gap between the knife heads to control coating thickness and achieve various coating effects.
Our curtain coating machines offer a choice of a large-flow paint heating and filtering box or a small-flow paint filtering box to match the different characteristics of UV or polyurethane coatings. They ensure that air bubbles and other impurities are removed from the paint before use, while the low-speed, heavy-duty impeller pump ensures a stable supply to the machine's knife body.
