Description

Shot peening technology

There are three types according to shot blasting application. 1. shot blasting cleaning 2. shot peening 3. shot peening forming  shot peening is traditional surface treatment technology, the principle is : by means of impacting of high speed shots on the workpiece, to make it plastic deform in order to produce residue stress, and increase the bent/twist fatigue strength of parts, improve stress corrosion splitting performance. The shot peening is a process of cooling, that is numerous round shots beating on the surface, like a micro hammer beating on the surface to produce small indentation and hollow.  
 
You can imagine, in a pressure stress area, split is hard to form or extend. As almost all the fatigue and stress corrosion occur on the surface or near the surface, thus by shot peening, the lifetime of spare parts can be extended. The residual stress by shot peening must reach half of the tensile strength of part material.   
 
 The notable enemy of metal fatigue failure is tensile stress. The production of tensile stress is due to alternate load by exterior or residual stress of production process like welding, grinding. Tensile stress tries to stretch or pull the surface to cause split in the final.

Digital control shot peening machine for aviation industry 

In the aviation industry, it has higher requirement, not only the spare parts material should be light, but also it can bear extreme load in bad environment. By virtue of protecting the surface of spare parts from exterior destroy and extend the lifetime, our surface treatment can improve the whole performance of spare part.
Most of the spare parts used in aviation industry, including airplane frame, wings, motors, landing gear, driving device, or transmission parts( gear); all adopt shot blasting treatment to meet its performance specifications.

Digital control shot blasting formed machine tool
Shot peening is a good way to form a complicated air power curve. This process without the module for the formation of airplane wing is ideal. It can also be used to remove the distortion of complicated parts due to processing or hot treatment.

Shot peening is a good way to form the complicated air drive curve, this is the ideal process to form the airplane wing, this process can also be used to remove distortion caused by processing or heat treatment of complicated parts.
The process can improve the performance of lifting, and reduce oil consumption and environment pollution.
The shot peening formation can be used to meet requirements of surface curvature, thickness, shape, and reinforced rib and process deformation.
The shot peening formation is a way to save money, used by many airplane manufacturers. It need no mould, so the expensive mould developing and manufacturing fees can be saved.
