What Is a Manual Powder Coating Machine? | Haztek Powder Coating Solutions

A manual powder coating machine is an electrostatic spraying system designed for flexible, efficient, and high-quality powder coating applications. With a large powder capacity and a fully portable design, it is ideal for small workshops, custom coating businesses, and industrial manufacturers that require consistent finishing performance.

This type of electrostatic powder coating machine uses an advanced control panel that is easy to operate, allowing users to adjust powder flow, electrostatic charge, and spray patterns with precision. During the coating process, electrostatically charged powder particles are sprayed onto grounded metal parts to create a strong and uniform finish.

How Does an Electrostatic Powder Coating Machine Work? | Haztek Powder Coating Technology

An electrostatic powder coating machine uses high-voltage electrostatic charging technology to apply dry powder particles onto grounded metal surfaces. This advanced finishing process delivers excellent coating adhesion, uniform coverage, and superior durability compared with traditional liquid paints.

Step-by-Step Working Principle of an Electrostatic Powder Coating Machine

1. Powder Feeding System

The powder coating machine draws powder from a hopper or vibration feed table. Compressed air fluidizes the powder, allowing it to flow smoothly into the spray gun.

2. Electrostatic Charging of Powder

Inside the spray gun, the powder particles pass through a high-voltage electrode (typically 60–100 kV). When the powder is sprayed, each particle becomes electrostatically charged.

3. Attraction to the Grounded Workpiece

The metal part being coated is properly grounded, creating an opposite electrical potential. The charged powder particles are strongly attracted to the surface and “wrap around” edges and curves, improving coverage and transfer efficiency.

4. Powder Deposition and Film Formation

The powder forms a soft, even layer on the workpiece without dripping or sagging. The electrostatic force helps the powder stay in place before curing.

5. Curing in a Powder Coating Oven

After spraying, the coated parts are placed into a powder coating curing oven. Under controlled temperature (160–200°C), the powder melts, flows, and chemically crosslinks to form a hard, durable protective film.
