A coating head is a key component in coating equipment. It is used to uniformly apply fluid materials such as coatings, glues, and inks onto the surfaces of various substrates like paper, plastic films, metal foils, and artificial leather. It is widely used in industries such as packaging, printing, electronics, and leather manufacturing to endow substrates with specific properties, such as water resistance, stain resistance, decoration, and conductivity.
-
Uniform Coating: Can achieve high-precision control of coating thickness, with the coating thickness deviation controllable within ±2%, ensuring the formation of a uniform and flat coating on the substrate surface. It can also ensure coating uniformity for substrates with a width of 1-3 meters.
-
Flexible Adjustment: The coating amount can be flexibly adjusted according to production needs. By changing the structural parameters of the coating head (such as slit width, metering roller gap), fluid pressure, and coating speed, it can adapt to materials with different viscosities (1-10,000 centipoises) and coating amount (5-200 g/m²) requirements.
-
Quick Switching: Some coating head designs are convenient for quick replacement or cleaning, and can complete the switching of different coatings or different processes in a short time (15-30 minutes), improving production efficiency and reducing downtime.
-
Coating Width: Common specifications include 600mm, 1000mm, 1500mm, 2000mm, 3000mm, etc. It can be customized according to the substrate width of the production line.
-
Working Pressure: The fluid delivery pressure range is generally 0.1-1MPa, specifically determined according to the coating viscosity and coating requirements.
-
Adapted Fluids: Suitable for various types of fluids, including water-based, solvent-based, UV-curable coatings, and materials such as hot-melt adhesives.
-
Packaging Industry: Apply barrier layers, moisture-proof layers, or printing inks on packaging paper and plastic packaging films to improve the performance and aesthetics of packaging materials.
-
Printing Industry: Used to apply pre-coating adhesives, varnishes, etc. on paper and films to enhance the gloss, abrasion resistance, and water resistance of printed products.
-
Electronics Industry: Apply conductive pastes, insulating coatings, etc. on the surfaces of electronic materials such as flexible circuit boards and display substrates.
-
Leather Manufacturing: Apply decorative layers, waterproof coatings, wear-resistant coatings, etc. on the surfaces of artificial leather or natural leather to improve the appearance and performance of the leather.
