Ultrasonic Testing (UT) is a process by which a transducer introduces an ultrasonic pulse to a substrate. The ”pulse-echo” effect of Ultrasonic waves can be measured and defects internal to the material will show up with an amplitude on a receiver for the return of the pulse through the material. … Read more >
Fluorescent Penetrant Inspection (FPI) is a process by which a high sensitivity dye is applied to a non-porous material in order to detect defects in the substrate. FPI ranges from low sensitivity, similar to red dye inspection to high sensitivity penetrants requiring several steps in order to develop the fluorescent dye to find minute defects in the substrate.… Read more >
Magnetic Particle Inspection (MPI) is a process used to detect surface and subsurface defects in ferromagnetic materials, such as Iron (Fe), Nickel (Ni), Cobalt (Co) and related transition metal alloys. MPI is a standard process in a variety of industries including Aerospace, Transportation (Automotive, Locomotive, etc.)… Read more >
Sinto Surface Technologies has the capability to polish a variety of components requiring enhanced surfaces, with requirements that do not meet the “super finishing” level of surface finish. The basic process routinely achieves surface finishes of 25 µin Ra and can be modified to achieve surfaces in the 10-15 Ra.… Read more >
Texturing is a process utilizing an abrasive media stream propelled against a surface at a high velocity to enhance or modify the existing surface. The purpose for texturing a component could be for any number of reasons, such as providing improved adhesion or friction properties or aesthetics.… Read more >
High-energy mass finishing describes any form of abrasive media-based parts finishing that uses more than the force of gravity and vibration to deburr, radius, smooth, burnish, descale or otherwise prepare parts. High energy processes use centrifugal force and other mechanical leverage to increase the aggressiveness of the finishing process, versus standard vibratory processes, reducing time and increasing the rate of removal of unwanted surface materials on a variety of wrought, cast and forged components. … Read more >
Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten a large number of work pieces. Sinto Surface Technologies uses both bowl and tub type vibratory units to provide both coarse and fine surface finishes as is appropriate. … Read more >
Sinto Surface Technologies has the process capability to super finish Aerospace, Medical Implants and other components requiring highly polished surfaces. The basic process routinely achieves surface finishes of 20 micro inch / 0.5 micrometer surfaces and can be modified to achieve 10 µin / .25 µm Ra surfaces or better.… Read more >
Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of a component. It entails impacting a surface with shot, applying sufficient force to create plastic deformation.
The process is typically used for components to increase fatigue strength and resistance to stress-corrosion cracking for parts such as axles, springs (helical, torsional and leaf), gears, shafting, aircraft landing gear, structural parts, especially life-limited aircraft engine components such as airfoils and disks, as well as similar items but usage is not limited to such applications.… Read more >
