Compressive stress helps prevent crack formation > Peened aerospace parts offer an increased fatigue resistance and improved operating life The shot peening process works by introducing residual compressive stress in the surface of the component. The compressive stress helps to prevent crack initiation, as cracks cannot propagate in the compressive environment generated by peening.Compressive stresses are generated when the impact of each particle of shot on the component produces a small indentation. It follows that if the surface has been dented then the material beneath the dent has been...

pockets for lubricant retention; it also reduces the surface area in contact under rolling or sliding conditions, thus reducing friction. Peening also has a surface hardening effect and helps the ֑skin of the material to resist wear. These characteristics, when combined, provide excellent anti-galling properties making your components more resistant, harder working and providing increased efficiency.Corrosion Җ intergranular and stress corrosion cracking can be inhibited by shot peening which modifies the properties of the metal at a metallurgical level. The process advantageously alters...

Peen forming - increasing strength regardless of size Peen forming is a variation of shot peening. The forming of wing skins by pressing or rolling can introduce the tensile stresses that are responsible for the initiation and propagation of cracks. Because shot peening introduces compressive stresses, it is possible to form thin components like wing skins into shape, simply by Process selection is critical to performance Equipment and process selection, whether to employ a compressed air system with blast nozzles or a wheel blasting technique, are of paramount importance when developing...

Impact Finishers, the sub-contract division of Wheelabrator Group has passed an in-depth examination to receive the aerospace industrys acclaimed NADCAP accreditation. The distinction applies to Impact Finishers sub- contract shot peening facilities in the UK at Slough and Coventry. Launched in 1990 by the Society of Automotive Engineers, Nadcap is a universal standard administered by the not-for-profit Performance Review Institute (PRI), to ensure manufactured aircraft and aero-engines are of the highest quality. It is now specified by the majority of prime manufacturers in these...

Flexible even for special components Innovation giving you total control Customer Focused Blast Solutions The flexible nature of the double-frame technology also allows special components to be blasted without interfering with normalђ production runs. Special workpiece carrying frames are used which are equipped with manually or automatically loadable workpiece supports and are easily entered into the blast chamber via inlet openings. This reduces the set up times and also solves the safety problems generated by manual loading in an automatic production line. After the special components...

Optimum ergonomics and easy maintenance: The whole installation is soundproofed not to exceed a 75 dbA sound level. The motorised front main entrance door provides complete clearance of the working zone, yet minimizes the layout space. For improved ergonomics, the main access zones for operators and maintenance procedures are located at ground level. Additionally, a stairway and secured platform allow easy access to the higher levels.After 12 months of production, this machine has successfully passed the most demanding qualification programme, and has been entitled to join the prestigious...

Bespoke solutions to meet your specific needs The RTM range of equipment from Matrasur Composites has been specially manufactured for the aerospace industry. RTM or Resin Transfer Moulding is a low pressure injection transformation technology and ensures a total control of injection parameters: flow rate, pressure, temperature, quantities. Injection is carried out according to the desired requirements and the injection process is traceable, repeatable and complies with environmental regulations. The machines offer accuracy and control with an excellent quality result. > RTM offers accuracy...

Wheelabrator Group teams up with Sonats to relieve stress in China > The Stressonic process is very repeatable which is a key point within the aerospace industry. There are only three parameters to be controlled: mass of balls, time and vibration amplitude of the sonotrode. All are continuously controlled during the treatment. The Beijing Aeronautical Manufacturing Technology Research Institute (BAMTRI), was interested in this new process and after few demonstrations was convinced that this was the solution to their shot peening issue. Bamtri bought a Stressvoyager unit and is operating it...
