How to choose a right liquid electrostatic spray gun?

The following is a practical guide for selecting liquid electrostatic spray guns, combined with core parameters, application scenarios, and brand characteristics:

1、 Clearly define the spraying requirements

Scale of homework

Small batch/sampling: Choose hand in hand dynamic models (weight ≤ 500g), support quick color change and cleaning

Production line: prioritize automatic spray guns such as Hongda HDA-90 auto electrostatic spray gun, or rotating bell spray gun such as HDA-605 electrostatic rotating bell spray gun ),

Compatible with robot integration Coating characteristics

Viscosity: For high viscosity coatings (such as epoxy paint), a large-diameter nozzle (≥ 1.8mm) should be selected

Water based paint requires a dedicated electrostatic model

Conductivity: Non metallic workpieces (plastic, wood) need to undergo conductivity treatment in advance

Comparison of core parameters

Nozzle selection:

round nozzle: wraps small workpieces (screws, beads)

Fan nozzle: fast coverage of flat surfaces (door panels, metal sheets)

Maintenance cost:

Choose ceramic nozzle+tungsten steel valve core (Hongda HDA-100), with a lifespan three times longer than ordinary parts

Avoid soaking the gun body in solvents and maintain it with a soft bristled brush and specialized cleaning agent.

In recent years, many foreign agents have also developed and received good reviews. HDA electrostatic spray gun is the best cost-effective choice for both domestic and foreign users. For the service aspect, it is also very good. Every year, technicians are arranged to provide on-site support for local exhibitions organized by agents. HDA factories in countries with agents do not directly hold any exhibitions, allowing opportunities to be given to local agents.

What are the models of spray guns available

Manual liquid electrostatic spray gun
