Robotic Shot Peening Standards & Compliance

Guyson operates an ISO 9001-certified Quality Management System, providing customers with the assurance that all surface finishing equipment is designed, engineered and manufactured through controlled, documented and continually improved processes.

ISO 9001 certification supports key requirements, such as consistent product quality, full traceability, effective risk management and a structured approach to continual improvement.

Underpinned by robust quality assurance, Guyson processes help manufacturers reduce operational risk, maintain confidence in equipment performance and support specification compliance. For manufactures operating in regulated industries, this quality-driven approach provides a strong foundation for audit readiness, long-term reliability and sustained operational excellence.

Guyson has over 88 years of extensive experience manufacturing AMS2432 Computer-Controlled Shot Peening systems. Our controlled processes utilise real-time monitoring, process traceability and documented parameter verification to ensure consistent peening intensity, coverage and repeatable results across production batches.

By maintaining rigorous process controls, Guyson help leading OEMs and MRO organisations worldwide to meet industry standards, improve component fatigue performance and demonstrate full compliance for critical parts processed on AMS2432-specified equipment and systems.

For manufacturers operating in aerospace, defence and other highly regulated industries, Guyson robotic shot peening systems are engineered to support the process control, monitoring, repeatability and traceability requirements associated with Nadcap accreditation and other critical process specifications.

Leveraging over 88 years of extensive application and process engineering expertise, Guyson systems provide precise control and verification of key parameters including blast pressure, media flow, spindle speed, nozzle position, traverse speed and component coverage, helping manufacturers minimise process variation, maintain specification compliance and generate the documented process required for audit readiness. The result is a robust, repeatable and fully traceable surface treatment process that supports quality assurance objectives, customer requirements and the rigorous demands of aerospace and defence manufacturing.

Blast media quality is critical for achieving consistent shot peening performance, surface coverage and specification compliance. Media size, shape, hardness and cleanliness directly influence process outcomes, making effective media control essential for quality assurance and process reliability.

Shot Peening Media Types

• Cast Steel Shot is the most widely used shot peening media, offering excellent durability and process consistency across a wide range of industrial applications
• Ceramic Shot provides reduced contamination risk and is commonly used for aerospace and non-ferrous applications
• Glass Bead is used where lighter peening intensity or surface conditioning is required
• Cut Wire Shot is known for its dimensional consistency and predictable peening performance, making it ideal for high-precision applications

Media Control & Verification

To maintain process integrity and compliance, Guyson robotic systems can incorporate:

• Separation Sieves to classify shot by size and remove oversized or undersized particles that could alter peening performance
• Roundness Classifiers to ensure media shape remains within specification by separating non-spherical or degraded media that may affect peening consistency
• Reclamation Systems to recover, clean and recycle usable media while removing contaminants, broken shot, and dust
• Media Monitoring Equipment to support the control of shot size, shot hardness, media shape, contamination levels and media flow consistency

As Europe's leading blast and ultrasonic test centre, Guyson provides process qualification, application development and operator training to help customers establish validated shot peening parameters with confidence. A key element of this process is Almen strip testing, the globally recognised method for verifying shot peening intensity and ensuring compliance with customer and industry specifications.

By combining expert testing, process analysis and practical application knowledge, Guyson help manufacturers develop data-driven shot peening solutions capable of processing safety-critical components with confidence, consistency and full traceability.

Achieving the correct shot peening intensity and surface coverage is essential for component performance, fatigue life and specification compliance. Guyson combines advanced process validation, precision controls and automated inspection technologies to help manufacturers verify critical process parameters, maintain consistency and demonstrate quality assurance across production.

Blast Pressure & Velocity Control

Closed-loop digital pneumatic controls provide precise regulation of blast pressure and velocity, helping to maintain stable peening intensity throughout the process. Key benefits include: consistent peening intensity, real-time process adjustment, reduced process variation, enhanced specification compliance, improved process traceability

A state-of-the-art shot peening sensor measures in-flight shot media velocity, helping to ensure peening consistency, quality control, faster process development and set-up transfer.

Abrasive Flow Control

MagnaValves deliver accurate and repeatable abrasive flow control, ensuring a consistent media stream throughout production. By regulating media flow, MagnaValves help maintain: shot velocity, abrasive flow rate, peening intensity, process stability, surface coverage consistency

Vision Systems & Coverage Verification

Integrated 2D and 3D vision systems provide real-time monitoring of component positioning, robot path execution and process completion, supporting greater accuracy and process verification. Vision systems can be used for: surface coverage verification, component identification and tracking, part presence detection, robot guidance and positioning, automated inspection and quality control.

Advanced robotic programming is critical to achieving accurate surface coverage, process consistency and specification compliance in automated shot peening and blast finishing applications. Guyson robotic surface finishing equipment can be programmed to optimise nozzle positioning, stand-off distance, traverse speed and coverage across complex component geometries. Helping to reduce commissioning time, minimise process risk and support the quality, traceability and control requirements of aerospace, defence and other highly regulated industries.
