Powder Coating System for Manual Coating Equipment, GC20FZ with Vibratory Box Feeder
Powder hopper Capacity 50L
Output Voltage 100kV
Input Pressure 5.5-6bar
Maximum Powder Output 520g/min
To meet the growing demand for small-batch production, multiple product varieties, and fast delivery in modern manufacturing, the Powder Coating System for Manual Coating Equipment, GC20FZ with Vibratory Box Feeder provides a highly flexible coating solution. Its main advantage is the replacement of the traditional powder hopper with an inclined vibratory platform design. Operators can place the original powder box directly on the vibration table, allowing the suction tube to draw powder straight from the box. With the support of a 150W high-frequency vibration motor installed at the base, the powder is guided toward the pickup point through the combined effect of gravity and mechanical vibration, helping improve powder utilization.
This direct powder feeding design eliminates the need to clean the hopper after every color change. It is an ideal choice for flexible production lines, color sampling rooms, and small processing workshops.
For R&D environments that test dozens of colors each day, operators only need to replace the powder box and activate the one-touch hose cleaning function to complete a color change in as little as 2 minutes.
Customized Small Metal Parts
Suitable for small-batch and multi-color coating of aluminum parts, motorcycle accessories, sheet metal parts, metal panels, radiators, and fan housings. This design helps minimize powder waste caused by hopper cleaning during frequent color changes.

System Components
This system mainly includes the GC20 main control unit, MG20 manual spray gun, PPH40 powder pump, powder hose (12 × 18 mm, 6 m), pressure regulating valve and air distribution unit, standard powder hose connection accessories, and Nozzles & Spare Parts.
High-Performance Spray Gun Control Unit
The control unit is equipped with digital valve technology and PCC precise current control, helping maintain stable airflow and pressure during the coating process. It also provides precise current adjustment below 10 µA, which helps prevent powder overcharging and improves coating stability and quality.
The GC20A controller supports up to 20 programmable coating programs, and each parameter set can be saved automatically for quick recall in future production.
It is equipped with a CANOpen communication module and provides an EDS file, offering strong support for secondary development and equipment connectivity.
The system features built-in self-diagnosis and one-touch cleaning. The self-diagnosis function monitors the operating status automatically and alerts users to potential issues in time.
The one-touch cleaning function greatly simplifies spray gun cleaning and maintenance, helping improve color change efficiency.
Three preset coating modes are available for flat parts, recoat parts, and complex parts. With dedicated buttons, a touchscreen, and a stepless adjustment knob, the controller enables fast and efficient operation.

MG20 Manual Spray Gun
The MG20 manual spray gun is equipped with a built-in 100 kV high-voltage module and is suitable for most standard powder types.
Its built-in 100 kV high-efficiency voltage multiplication circuit ensures stable output for better coating performance. In addition to handling most common powders, it can also coat materials that are traditionally difficult to charge. Its wear-resistant design and carefully selected materials also help reduce maintenance costs.
The MG20 spray gun features an ergonomic design and weighs only 510 g, combining light weight with strong durability. Its unique spray angle and handle design help reduce operator fatigue during long working hours. The external remote control module allows coating parameters to be adjusted easily, and preset coating programs can be switched quickly by double-clicking the trigger, helping improve working efficiency.
PPH40 Powder Pump
Suitable for fast color change and quick cleaning, the PPH40 powder pump features a plug-and-play design for fast installation, fast color change, and quick cleaning. Its quick-connect powder hose structure makes hose removal and reconnection easier during cleaning. The venturi tube is made of high-quality non-stick material and is fitted with a quick connector for compressed air. It delivers stable and even powder feeding with excellent atomization, helping produce high-quality coatings. The maximum powder output can reach 520 g/min, depending on the actual configuration and powder type.
Vibration Table
The vibration table uses high-frequency vibration to keep powder particles suspended and break up agglomeration caused by gravity or electrostatic attraction, resulting in better powder flowability. It also reduces friction between powder particles, helping maintain a stable and consistent powder supply to the spray gun over time. This system draws powder directly from the original powder box, so there is no need to replace or clean the hopper during color changes.
