In the world of manufacturing today, the potential liability of shipping a defective part is catastrophic to you, your customer, and the consumer. Non-Destructive Test--Resonant Acoustic Method (NDT-RAM™) inspection is designed to help you deliver fully inspected parts, economically and on-time, giving you confidence in the quality of your parts.

The principle of NDT-RAM is simple. Every part has a unique resonant signature or pattern that reflects its composition. Any deviation from the expected signature or pattern indicates the presence of a flaw or variability. A familiar example is a cracked bell, which no longer has a clear ring and cannot hold its tone.

NDT-RAM detects imperfections such as variances in dimension, geometry, weight, voids, cracks, density, bonding, and manufacturing processes. The entire procedure takes seconds per part, allowing for efficient quality-control testing of all parts in your process line.

Resonant Acoustic Method

Currently, there are three available configurations of the NDT-RAM™ system:
NDT-AUTO NDT-SEMI NDT-MAN

Fully Automated NDT-RAM System

• Ideal for in-line, automated, objective inspection
• No operator intervention needed for inspection
• 100% inspection to test every part prior to shipment
• Fast throughput - as fast as a part per second
• Customizable conveyor configurations

 Semi-Automated NDT-RAM System

• Ideal for adapting to existing process automation
• 100% inspection to test every part prior to shipment
• Fast throughput - as fast as a part per second

Manual NDT-RAM System

• Portable - fits easily inside a laptop case
• Ideal for spot checking in the field
• Ideal for new part set-up, investigation, troubleshooting

Who needs NDT Resonant Inspection?
Manufacturers or users of metal parts that
• Have substantial inspection cost
• Require 100% inspection of their parts
• Desire to improve quality of their parts
• Produce and/or use safety-critical parts
• Have customers demanding higher quality
• Have substantial scrap costs due to false rejects
What does NDT Resonant Inspection detect?
• Cracks, chips, and holes
• Porosity
• Out-of-tolerance dimensions
• Variations in hardness
• Residual stress
• Bonding, welding, or brazing failures
• Machining or heat-treating processes
Benefits
• Extremely Portable -- fits easily inside a laptop case
• No "part preparation" required
• Parts are fully inspected in seconds
• Reduction of scrap costs with elimination of false rejects
• Easy to learn and use application software
• Report generation, including statistical analysis
• Industrial packaged -- NEMA4 enclosure
• Contact or non-contact test many different parts
• Same system can test many different parts
• Confidence that all tested parts are defect-free
