Non destructive testing

Products, equipment and accessories for penetrant and magnetic particle testing, and ultrasonic couplants for aerospace and other industries through our subsidiary Babbco and partner, Sherwin Babbco. Our dedicated NDT Technical Engineering and Support Team assists our customers from product recommendation through to delivery, maintenance and after sales service.

Magnetic particle testing

Magnetic particle testing is a test method used globally to detect surface discontinuities. Parts can be locally or fully inspected. MT is dedicated to ferritic steel, and can be performed manually in situ during maintenance (MRO), or automated close to a manufacturing line (OEM).

How does MT work? The part is magnetized and iron particles applied to the surface. Discontinuities affect the flow of the magnetic field, causing the applied particles to gather at locations of flux leakage, producing a visible indication of the irregularity on the surface.

Penetrant testing

Penetrant testing is another test method used globally to detect surface discontinuities. Parts can be locally or fully inspected. It can be used on all metals and other non-porous materials such as ceramics, some plastics and composites. PT can be can be performed manually in situ during maintenance (MRO), or automated close to a manufacturing line (OEM).

How does PT work? A dye solution is applied to the surface to penetrate any surface breaking cavity. Once the excess solution is removed, a developer is applied to draw out any unseen penetrant. With visible dyes, a colour contrast between the penetrant and developer makes the ‘bleed-out’ easy to see. With fluorescent dyes, UV light makes the ‘bleed-out’ fluoresce brightly, allowing imperfections to be seen.

Lighting

PT and MT use white or black lights (UV—A), depending on whether the dye or particles are visible or fluorescent. Both techniques are based on contrast ratio (luminous and colour contrast). We offer a wide range of lamps and accessories, depending on the method used and the needs.

Ultrasonic Testing

Ultrasonic Testing  (or UT) is a method of characterizing the thickness or internal structure of a test piece through the use of high frequency sound waves.

How does UT work? High frequency sound waves are transmitted into the material. When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected back from the flaw. We provide coupling agents in the form of paste and gels to facilitate the transmission of the ultrasonic energy into the material.

Replication systems

Replication materials are elastomer products that offer fast setting, dimensionally stable measurement of tooling, mold making dies, gears, prototype tooling, production parts and surface finish replications, as well as a number of other applications.

They are an ideal material for measuring wear on moving parts, production pieces against specification tolerances, overall quality of machined or plated surfaces, in conjunction with optical comparators, and corrosion pitting.
