Part 334627−05 E 2015 Nordson Corporation Description 2-1

Section 2 Description

Introduction The Sure Coat automatic powder spray gun electrostatically charges and sprays organic or metallic powder coatings. It is used with a Sure Coat automatic gun control unit, or a Sure Coat Modular Gun Control System, or an iControl system.

Features See Figure 2-1 or 2-2.

The spray gun features a straight-through powder path, which minimizes surfaces for impact fusion to occur. The rigid powder tube and all powder path components are easy to remove, clean, and inspect.

The negative-polarity, integral power supply (voltage multiplier) is user-replaceable. All spray guns are equipped with gun air to prevent powder from collecting on the electrode.

The quick-disconnect hose connector (1) allows the operator to quickly switch powder feed hoses while performing a color change.

Mounting Configurations The spray gun is available in both bar- and tube-mount configurations.

Refer to Table 2-1 for a description of the variations available for both mounting configurations.

E 2015 Nordson Corporation Part 334627−05 2-2 Description

Mounting Configurations (contd)

Table 2-1 Mounting Configurations Gun Type Variations Illustration Tube-mount The tube-mount gun is available in the following lengths: Figure 2-1 S 0.91 m (3 ft) S 1.22 m (4 ft) S 1.52 m (5 ft) S 1.83 m (6 ft) Bar-mount The bar-mount gun may accept either of the following size gun Figure 2-2 bars in any lengths: S 1 1 /4-in. OD S 5 /8-in. OD 1 NOTE: The 1 /4-in. OD gun bar is a new, larger diameter, rigid bar. Refer to Parts for ordering information for the standard 3- and 4-ft long gun bar mounting assemblies.

Theory of Operation See Figure 2-1 or 2-2.

The control unit supplies low-voltage dc power to the voltage multiplier in the spray gun body (2). The multiplier converts the low-voltage dc power to the high electrostatic voltage needed for powder coating. The voltage generates a high-strength electrostatic field between an electrode in the nozzle (3) and the grounded part in front of the spray gun. The electrostatic field produces a corona discharge around the electrode.

Flow rate air pressure pumps the powder from the feed hopper, through the feed hose, into the hose connector (1), and out through the spray gun’s nozzle. As the powder particles are sprayed past the electrode in the nozzle, they pick up an electrostatic charge and are attracted to the grounded parts.

The spray pattern is controlled by the shape of the nozzle, the flow rate air pressure, and the electrostatic field generated between the electrode and the grounded part.
