Automatic Powder Coating Machine Manufacturer for Internal Spray Bottle

Common Application Scope

The internal bore fully automatic spraying machine is suitable for inner wall coating of round pipes, cylindrical structures, and deep-hole components. It is widely used for products that require anti-rust, insulation, or functional coating performance. This type of system is often combined with an automatic coating machine setup for stable production efficiency.

Common Industries

• Inner wall coating for pipes and cylindrical structures
• Internal and external coating for cosmetic boxes and containers
• Internal coating processing for various bottles and containers

HD-220 Coating Machine Advantages

Multi-Station Simultaneous Production

• When equipped with four spray guns, up to four products can be processed at the same time

High-Efficiency Spraying Design

• Automatic up-and-down spraying reduces blind spots
• Spraying stops when the workpiece is repositioned, reducing material waste

Flexible Operation Adjustment

• Spraying speed, cycles, and pressure can be adjusted based on requirements
• Rotation and revolution speeds are adjustable for different product types

HONGDART provides practical system design as an experienced powder coating machine manufacturer, helping customers build stable and efficient coating production lines.
