Introduction
Behind every successful HVOF or plasma spraying operation lies a network of ancillary equipment that makes consistent coating production possible. From powder feeders to cooling systems, these auxiliary components are essential for quality, safety, and efficiency.
What Is Ancillary Equipment?
Ancillary equipment refers to all supporting systems that work alongside the spray gun. These include motion control, powder feeding, cooling, surface preparation, ventilation, and safety systems.
While the spray gun gets the spotlight, ancillary equipment often represents a larger investment. Machining equipment alone can cost €200,000–€1 million, while robots and quality control systems each require €75,000–€200,000.
Key Categories
Motion Control
The thermal spray environment—high temperatures and noise—makes handheld spraying unsafe. Common solutions include turntables, X-Y manipulators, and six-axis robots.
Powder Feeders
These deliver consistent material flow using rotary feeders with digital controllers. For fine WC-based powders, static-dissipating hoses are essential.
Cooling Systems
Supplemental air cooling controls part temperature and removes overspray debris. For flat surfaces, coolers go on both sides of the spray stream.
Control Consoles
Modern systems use PLC-based controls with touch-screen HMIs and remote diagnostics. Safety interlocks and automatic shut-offs are standard.
Surface Preparation
Grit blasting equipment (€10,000–€40,000) prepares surfaces before coating. Systems include blasting cabinets and dust collection.
Ventilation
HVOF generates significant fumes and overspray. Ventilation systems (€30,000–€45,000) protect operators and ensure regulatory compliance.
Integration
Coating process cells combine motion control, inspection, and robotics in one automated system—ideal for high-volume, precision-critical applications like aerospace and medical devices.
Conclusion
Ancillary equipment is the backbone of thermal spray operations. As HVOF technology advances, so does its supporting infrastructure—enabling better coatings and safer workplaces.
