SINTOKOGIO manufactures Shot Peening, Abrasives ,Shot Peening Machines.

Blasting steel abrasives, or other media on the surface of parts causes compressed
stress, which, in turn, increases fatigue strength and resistance to stress-induced
splitting and corrosion cracks.
Shot peening applications are now expanding from traditional auto and aircraft parts
into many new areas which demand a higher grade of reliability, durability and
ligher weight.

1.	A variety of shot peening machines employing either wheel of nozzle projection systems.
2.	Superior quality shot from fine beads as small as 44 microns to larger sizes, each size suitable to different applications.
3.	Laboratory testing and analyses assure the proper combination of conditions for maximum peening results.
4.	Prompt after-sales technical and maintenance services.
5.	"3 in 1" Equipment, shot, and Engineering through Sinto's global network.

Sinto manufactures a wide array of shot peening machines with two different projection
systems: the wheel type projects large amounts of shot over a wide area, and the other
is the air nozzle type projects shot over a limited area.

This high productivity machine treats products having large surfaces, by employing
one or more wheels rotating at a speed of 2000 to 3600 rpm to project large quant-
ities of shot.

The air nozzle peening machine utilizes compressed air to project shot from the
nozzle. Computer numerical control (CNC) allows for easy selection of projecting
speed, shot amount, angle, and distance from workpieces. This method effectively
applies peening to specific areas of workpieces. This style can be integrated into
an inline manufacturing system.

*Peening Results Maxmized through Analyses
	Sinto tests, then eveluates peening quality. The results of numerous tests are evaluated using various measuring instruments, such as precision X-ray stress devices and fatigue testers. By rigorous analyses, Sinto offers expert advice to achieve the best peening conditions.

*Integrated Monitoring System for Peening Condition

Maximum peening quality demands consistent and accurate control of many factors
affecting the outcome of the peening precess. Sinto developed integrated control
technology by which various sensors are attached to the shot projection control
system, shot control system, projection nozzle movement control, workpiece
positioning system, etc, so that optimal peening condition is maintained through
continuos monitoring.

Superior quality shot is essentinal for consistently effective peening.
Sinto's SB PEENING SHOT is produced under severe control using the latest
production facilities and the most advanced technology.
SB peening shot meets rigorous quality requirements for peening.

*	Uniform hardness
*	Consistent size
*	Free of internal defects

*	Uniform spherical shape
*	Microstructure to withstand high impact

*SB Peening Shot Satisfy Diverse Demonds
	SB Peening Shot is effecitively used in diverse applications, from precision peening to hard peening, depending on material, shape, hardness, and required finish.

*High Hardness Shot for Hard Peening
	Hard Peening is receiving a lot of attention recently. It is the technology of projecting shot with hardness of around HRC 60 at speeds of 80 to 100m/sec., onto metal surfaces to produce high residual stress, extending fatigue life several times compared to the results achieved by conventional peening technology.
