Curtain Coating Machine

Model SL-TLSU

The curtain coating machine is the most widely used equipment for flat product thick paint layer coating.

One alloy aluminum knife head recycles the liquid paint supplied by the pump from the paint container to create a paint curtain like a waterfall, two belt conveyors accelerate and decelerate to assist flat boards pass through the paint curtain very fast, coating a thick and evenly paint layer on their top side.

The curtain coating thickness is adjustable by knife head gap and conveyor speed, usually applied to PE, PU sealer, and UV topcoating to get the high gloss effect, suitable for wood, glass, fiber cement board, plate metals, PVC, ceramics, and marble, etc.

How does Curtain Coater work?

Base Materials

Wood
Glass
Metal Sheet

Advantages

High efficiency

It is suitable for rapidly coating large-area workpieces with high production efficiency.

High gloss effect

With precise control of coating fluidity and thickness, the curtain coating machine can easily achieve high gloss or mirror effects.

Even paint curtain

With the precise curtain system, the paint can flow evenly to form a continuous coating, avoiding sagging and ensuring a smooth surface.

Cost savings

Based on the recycling system, unused paint can be recycled and reused to reduce waste.

No air bubble

Equipped with a multi-layer filtering high-flow heating box, it filters impurities in multiple layers, eliminates bubbles, and achieves a high-fullness paint film.

Strong adaptability

It can handle products of different shapes and sizes and is suitable for a variety of surfaces such as flat surfaces and curved surfaces.

Standard Characteristics

Alloy aluminum knife

T6 heat process make entire knife better themal conductance, surface planish and electroplating process enhance its strength and compact, ensure wide knife paint fall smoothly.

Curtain coater head

Larger knife paint cavity supports more flow paint, one wheel to adjust wider curtain coater paint fall evenly and easily, mechanical adjustment ensures long-term precise regulation

Screw pump

Longer and thicker screw bar is working more stably, reduce the pump swing during work and decrease air bubble come. Flip type structure convenient to maintain entire bar.

UV paint container

Stainless steel filter paint case with electric heating function, internal 7 degree filters make more and longer paint stream loop ensure remove air bubble or any impurity.

FAQs

1. How to control the coating thickness with the curtain coating machine?

We have already adjusted the accuracy of the aluminum alloy knife head during production. There is a hand wheel near the knife head on the front of the machine. Adjust the gap of the knife head clockwise, and the thicker the coating will be. Adjust it counterclockwise, the thinner the coating will be.
2. What’s the difference between a split curtain coating machine and an integrated curtain coating machine?

In terms of design, the split curtain coating machine is composed of two conveyors and an independent curtain head. The integrated curtain coating machine is an integrated machine, in which the conveyor and curtain head are connected to one machine.

In terms of application, the split curtain coating machine can adapt to different production needs by adjusting individual components and is more suitable for industries that require frequent changes in coating materials or parameters. In addition, if there is a high requirement for coating uniformity, the performance of the split curtain coating machine is even better because the independent structure allows them to be unaffected by each other.

However, the integrated curtain coating machine also achieves similar goals with a lower cost, making it popular among manufacturers.
3. What are the wearing parts of the curtain coating machine?

Counter, replace the blade body rubber strip.
