High-efficient Fluorescent Penetrant Inspection Systems
Surface flaws too fine for the human eye decide whether a turbine disc flies or fails. PROMAG builds complete FPI lines — from a single compact station to a ten-station automated aerospace line — engineered in Taiwan and installed turnkey anywhere in the world.
Rigorously compliant with ASTM E1417, NADCAP, and the specifications of major global aerospace primes.

Why Choose PROMAG FPI?
30+ Years of Excellence
Designed and manufactured entirely in Taiwan on three decades of accumulated know-how. One contract covers engineering, fabrication, on-site installation, commissioning, and long-term technical support — wherever your plant is located.
Tailored
Layouts
Linear, L-shaped, and U-shaped configurations are all available as standard. Whether you are squeezing a line into a tight corner or installing oversized tanks, the layout is drawn around your floor plan rather than the other way round.
Smart
Conveyance
Choose manual handling, semi-automated assistance, or fully automated transport. Each level of conveyance is designed to take physical load off the operator while pushing throughput and workplace safety upward.
Industry-
Proven
Installed and running in aerospace manufacturing, MRO, automotive component production, and heavy industry — sectors where the tolerance for a missed indication is effectively zero.
Method Compatibility
Penetrant class is dictated by surface chemistry and susceptibility to chemical attack. PROMAG builds complete FPI systems around two principal removal methods.
Water-Washable (A)
Excess penetrant rinses away directly with water — the shortest route through the process, and the reason it suits high-throughput parts.
Post-Emulsified — Lipophilic (B) & Hydrophilic (D)
A specialized emulsifier step controls removal rather than rushing it, keeping penetrant where micro-flaws hide. Built for safety-critical aerospace components.
Versatile Plant Layout Configuration
No matter your footprint, PROMAG brings 30+ years of spatial engineering expertise to integrate FPI systems into your facility. Four proven configurations, each with a different trade-off.
One Straight Line
Workpieces enter at pre-clean and move linearly to the unloading area. The shortest, simplest route through the process — minimum part handling risk, best suited to fast-flowing plants with the length to accommodate it.
U-Shape Configuration
The line doubles back so loading and unloading sit side by side, letting one operator manage both ends. A significant footprint saver compared with a straight run of the same station count.
L-Shape Flow Design
Fits along your workshop's perimeter walls or corners, preserving valuable center space for heavy machinery and transport access. The usual answer when floor space exists but not in a straight line.
Two / Multi-Line Integrated
Parallel FPI paths share centralized, high-cost modules — ultrasonic post-clean systems, large ovens, multi-level darkrooms. Capacity multiplies without the capital cost multiplying with it.
PROMAG FPI Lines
From laboratory validation to fully automated aerospace production, PROMAG delivers standard-compliant, cost-effective FPI series.
