Glass bottle automatic spray coating system for cosmetic bottles, wine bottles, perfume bottles, and other glass bottles.

and also we produce automatic glass bottle interior coating machine, high efficiency and high quality with paint saving.

3 steps for glass bottle automatic spray coating system procedure.

Step 1: Painting for base coat : Clean products-Load products on line-Preheating (IR oven)--base painting--IR leaveling preheating--UV curing--cooling--off-line

Step 2: Vacuum coating/metallizing: load products in evaporation vacuum coating machine-metallizing-unload products

Step 3: Painting for top coat: load products on UV line-electrostatic cleaning-top coat painting-IR leveling preheating-UV curing-cooling-unload products.

Glass bottle spray painting operation skills :

1, with a clean thinner or water to the paint sprayed to the appropriate viscosity, measured by coating -4 viscometer, the appropriate viscosity is generally 18 to 30 seconds. If there is no viscometer, visual method can be used: with a bar (iron bars or sticks) to stir up the paint to 20 cm high to stop the observation, such as paint in a short time (a few seconds) Too thick; such as a break from the barrel along the line is too thin; to 20 cm high when the stop, the paint into a straight line, and instantly become broken down into the drip, the viscosity is more appropriate. In this case,
2, the air pressure is best controlled at 0.3-0.4 MPa (3-4 kg force / square centimeter). Pressure is too small, poor paint spray, the surface will form pitting: pressure is too large and easy to hang, and the mist is too large, both a waste of material and affect the health of the operator. In this case,
3, the nozzle and the surface of the general spacing of 200-300 mm is appropriate. Too close to easy flow hanging; too far paint mist is not uniform, prone to pitting, and the nozzle from the surface of the far paint mist in the way of flying waste. The specific size of the interval, should be based on the types of glass paint, viscosity and pressure to adjust the size of the appropriate. When the air pressure, the distance can be a little bit, the pressure can be close to a little hour; the so-called far point is a little far between the 10 mm -50 mm range of adjustment, the pressure is too small, If this range is exceeded, it is difficult to obtain a desired paint film. In this case,
4, the gun can be used for up and down, left and right movement, preferably 10-12 m / min speed of uniform action, the nozzle should be straight to the surface coating, minimize oblique spraying. When sprayed to the surface at both ends of the gun, the gun button to quickly trigger the pine look, so that paint mist, due to the two ends of the surface, often to accept more than two spray, is the most likely to cause sagging place. In this case,
5, when spraying under a pressure to suppress a 1/3 or 1/4, so as not to leak leakage phenomenon. In the quick-drying paint spray, the need for a spray in accordance with the order. Fill spray effect is not satisfactory. In this case,
6, in the outdoor open space when spraying, pay attention to wind direction (wind should not be operating), the operator should stand in the wind direction, to prevent the paint mist was blown to the paint film has been caused by the disgrace of the grainy surface. In this case,
7, spraying the order is: the first difficult after the first, after the first outside. After the first low after the height of the first small area after a large area. So that will not cause the paint spray after the spray has been sprayed on a good film, the damage has been sprayed a good film.
