Shot peening machine is a process specifically designed to enhance the fatigue strength of components which are subject to high alternating stress. It can help to prevent fatigue cracks, corrosion, deteriorated strength and premature fatigue that can be caused by machining and form metal parts which also creates internal stress concentration. It also helps to prevent crack formation and growth since typically fatigue cracks generally begin at the imperfection on the surface of the material.

Application of shot peening machine:

Crankshafts

Gear wheels

Connecting rods

Automotive gear parts

Coil springs

Turbine blade (Aircraft)

Airframe components

Suspension springs

Medical implants

Advantages Of Shot Peening:

It reduces stress corrosion splitting

It can prepare components for plating

It straightens fragments that were deformed when manufactured

It reduces casting permeability

It can alter part dimensions

It will improve oil retention

Transportation System:

2-4 rotating carousel chambers allow one chamber to process (shot blasting or peening) while others to load and unload work-pieces. A higher production efficiency is insured.

Hanger with self rotating function keep work-pieces rotating while processing for a high abrasive coverage.

Blasting chamber:

The engineering team uses 3-D dynamic simulation design blast turbines layout to ensure that the steel shot ray can cover the surface of the workpiece 360 degrees.

Shot blasting chamber with Mn13 steel guard plate which has high impact toughness and high service life, fully realize the reflection funcation of abrasive and improve the cleaning quality. That we promise 10 years maintenance-free warranty to blasting chamber.
