How Enamel Manufacturers Can Improve Spray Enameling Quality-Adjustment Methods for Enamel Spray Guns

In enamel production, the enamel spray gun serves as the key tool for wet spraying, applicable to nearly all enamel products. However, manual wet spraying demands high skill from operators, making proper adjustment of the spray gun crucial. Below we introduce methods for adjusting enamel spray guns. Enamel manufacturers are welcome to collect.

The nozzle size of the enamel spray gun is easily adjustable via a dedicated knob. Different nozzle sizes suit varying applications: small-nozzle guns are ideal for spraying small areas or intricate details, ensuring the enamel glaze slurry adheres more precisely to the product surface and maintaining coating quality in fine areas; large-nozzle guns are suitable for large-area spraying, enhancing work efficiency. Workers should flexibly adjust the spray gun nozzle size based on the product dimensions and coating requirements.

I. Nozzle Shape Adjustment

The worker can adjust nozzle shape by using the knob, allowing to select either a diameter nozzle or a fan nozzle based on actual requirements. The glaze emitted from a straight nozzle forms a column, making it suitable for requiring precise control over the spray area, such as localized coating of specific product sections. A fan nozzle disperses the glaze in a uniform fan pattern, providing broad coverage ideal for large-area, even spraying. This enhances coating uniformity and efficiency.

II.Air Pressure Adjustment

Air pressure directly impacts spraying results. Use the knob on the spray gun to adjust air pressure. Excessive pressure causes excessive glaze atomization, leading to waste and potential sagging on product surfaces. Insufficient pressure results in inadequate glaze atomization, uneven spraying, and compromised product quality. Operators must adjust air pressure appropriately based on glaze characteristics and product requirements to ensure optimal spraying results.
