1, Familiar test with the heat treatment, shot peening.

2, Paint Shop has a shot peening equipment.

3, One of environmental protection of sandblasting, shot peening oriented.

4, And when shot peening treater, the fatigue strength of the chian will improve 12.3 %.

5, The gear fatigue test showed that shot peening can improve its strength significantly.

6, On-line testing shows that, this digital ultrasonic peening power supply based on DSP can make the system work at the resonance state, and the peening process is stable.

7, Mechanic shot peening is a traditional process and widely employed by industrial circles.

8, Shot Peening ( SP ) is a typical severe plastic deformation method to produce ultra - fine grains of metallic materials.

9, Shot peening is also improved the stress relaxation ability of copper alloy.

10, The reverse torsion fatigue limit after shot peening and prestrain is higher 20-30% than that of ground one.

11, The proper peening process was presented on the basis of shot peening density and coverage test.

12, Business are: various sandblasting machine ( shot peening machines ) equipment and related product design, production and marketing.

13, Due to residual stress induced by laser shot peening can be deeper in depth.

14, Great improvement has been brought about in the service life of springs by hot peening.
