Surface Technologies

Product Description

Automatic Peening

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, and similar items but usage is not limited to such applications.

Blast Cleaning

Blast cleaning is a process utilizing an abrasive stream of media propelled against a surface at a high velocity to remove rust, scale, coatings, or other unwanted material.

Burn Off

Burn off cleaning is a method of removing unwanted coatings by a process known as pyrolysis.

Computer Monitored

Computer monitored shot peening is intended to provide a method of process observation, trace-ability, and response for all process input settings, in real time, during the entire peening process to ensure with objective evidence, the desired process outputs.

Consulting Services

we can offer consulting services to kick start your in-house surface processing objectives, support initial startup with redundant capacity, machine recommendations through Sinto America, installation of quality systems and other technical services.

Die Life Enhancement

D – SCC is our proprietary surface modification process for improving resistance to stress corrosion cracking (SCC)

Fixture Repair

Fixture Adjustment to maintain critical positioning and fixture fabrication and repair to your original design

Fluorescent Penetrant Inspection (FPI)

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

High Energy Mass Finishing

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

Mag Particle Inspection (MPI)

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

Manual Peening

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

Mobile Services

Sinto Surface Technologies offers mobile shot peening services for a variety of on-site applications including large industrial, transportation and infrastructural components and assemblies

Peen Conditioning

Peen conditioning is an Automatic Peening process typically performed on components such as airfoils after thermal coating


The basic process routinely achieves surface finishes of 25 µin Ra and can be modified to achieve surfaces in the 10-15 Ra.

Super Finishing

Sinto Surface Technologies has the process capability to super finish Aerospace, Medical Implants and other components requiring highly polished surfaces.


Texturing is a process utilizing an abrasive media stream propelled against a surface at a high velocity to enhance or modify the existing surface.

Ultrasonic Testing (UT)

Ultrasonic Testing (UT) is a process by which a transducer introduces an ultrasonic pulse to a substrate.

Vibratory Finishing

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.
