NKPT1800 Semi-Automatic Penetrant Testing Line for Precision Surface Flaw Detection

Semi-automatic fluorescent penetrant inspection line for precise NDT surface flaw detection in industrial applications.

  • Semi-automatic operation with PLC control for improved efficiency and process stability

  • Fluorescent penetrant method ensures high sensitivity in detecting surface cracks and defects

  • Modular station design allows flexible configuration for various part sizes and testing requirements

  • Stainless steel structure for enhanced durability and resistance to corrosion in harsh environments

  • Applicable to multiple industries including aerospace, automotive, energy, and precision casting

Our Semi-Automatic Penetrant Testing Line is designed for high-precision surface flaw detection using the fluorescent penetrant inspection (FPI) method. With semi-automated control and modular station design, this system offers an efficient and reliable solution for non-destructive testing (NDT) in various industrial sectors.

Equipped with PLC + HMI control, the line automates key processes such as pre-cleaning, penetrant application, emulsification, water washing, drying, and development. The semi-automatic configuration allows for optimal balance between cost and productivity, especially for medium-volume inspection tasks.

The entire system is built using corrosion-resistant stainless steel, ensuring long-term performance and minimal maintenance, even in demanding environments. Each testing station can be customized to meet specific component dimensions and inspection standards such as ASTM E1417, ISO 3452, or NADCAP requirements.


✅ Key Benefits

  • Increases inspection consistency and sensitivity with fluorescent dye penetrant technology

  • Reduces labor intensity and improves throughput compared to manual setups

  • Modular design enables flexible configuration for different parts and layouts

  • Compatible with international NDT standards and aerospace specifications

  • Ideal for applications in aerospace, automotive, casting, and pressure vessel manufacturing
