F1 Plasma Spray Gun: Dual-Angle Coating Technology Empowering Industrial Coating Innovation

F1 Plasma Spray Gun - Reliability and Flexibility Combined

FST’s F1 plasma spray gun is renowned for its exceptional reliability and consistent coating quality, designed to meet the demands of complex industrial scenarios. The spray gun采用模块化理念，提供90°和45°两种喷涂角度配置，适配不同工件结构与涂层需求。其核心优势包括：

• Long-life tungsten nozzle: Significantly extends component lifespan and reduces maintenance frequency and production costs.
• Compact spray head design: Suitable for small diameter internal hole spraying (e.g., 75 mm and above).
• Nitrogen compatibility: Supports nitrogen as the primary fuel gas, expanding its application range in sensitive environments.
• Stable and efficient operation: Capable of continuous high-power operation, compatible with general and advanced coating processes.

Why Do Traditional Spray Guns Only Offer a 90° Spraying Angle?

Traditional plasma spray guns typically use a fixed 90° vertical spraying design due to the following reasons:

• Simplified process: A vertical angle maximizes energy transfer in the spray stream, ensuring full powder melting, suitable for flat and external curved surfaces.
• Technical barriers: Oblique angle spraying requires addressing issues like energy decay in the spray stream and powder trajectory deviation. Traditional solutions rely on external mechanical deflection, which can lead to performance degradation and increased maintenance complexity.

F1 Plasma Spray Gun Dual-Angle Spraying: Precise Adaptation to Complex Needs

90° Spraying Mode (Standard Configuration)

The 90° spraying angle is the standard configuration for most spray guns, with key advantages including:

• Suitable for large-area external surface coatings, such as turbine blade outer walls and hydraulic cylinder protection.
• Excellent coating density and high deposition efficiency, ideal for applications requiring strict surface uniformity.

Due to these advantages, this spray angle is the most widely used, applied in many standard surface spraying operations, such as thermal barrier coatings for gas turbine components (external surfaces) and wear-resistant and corrosion-resistant coatings for mechanical equipment.

45° Spraying Mode

The 45° spraying angle is an innovative feature of the F1 spray gun, with core advantages including:

• Specifically designed for internal holes, deep grooves, and obscured areas, addressing blind spots traditionally difficult to reach.
• Inert material spray head avoids short-circuit risks when in contact with conductive components, enhancing operational safety.

As a result, the 45° spraying angle of the F1 spray gun is widely used in applications such as repair and reinforcement of aircraft engine combustion chamber inner walls and protective coatings for energy equipment internal surfaces, among others involving internal wall or unconventional surface treatments.

Core Value of the F1 Plasma Spray Gun: End-to-End Optimization from Design to Application

• Modular flexibility: Quick switching between 90° and 45° modules without complex adjustments, accommodating multi-task production needs.
• Process compatibility: A single nozzle configuration supports spraying various materials (e.g., metal alloys, carbides, and ceramic coatings).
• Cost-efficiency enhancement: Durable hardware design combined with economical component replacement options significantly reduces lifecycle costs.

The F1 plasma spray gun, through its 90° and 45° dual-angle configurations, balances high-precision external surface spraying with complex internal hole and groove scenarios. It has become the preferred solution in aerospace, energy equipment, and advanced manufacturing sectors. Its modular design, long-life components, and nitrogen compatibility provide industrial users with dual assurances of flexibility and economy.

Our company’s F1 electrodes are compatible with original equipment models such as 340001, 343001, 343010, 340002, and 343002. They ensure high dimensional accuracy while maintaining seamless performance integration. Their lifespan and stability are comparable to those of original parts, with the added advantage of cost-effectiveness, providing customers with a more economical electrode replacement option.
