Shot Peening Technology | Working with PCL | Benefits of Shot Peening | Typical Components | Typical Post-Peening Treatments
Plastic Coatings Ltd provides a specialist shot peening service
to achieve increased fatigue life and corrosion resistance, plus wider benefits on your components.
We recommend our shot peening service for components undergoing treatments such as stress relieving, phosphating, oiling, coating and plating – although our team will discuss the right processes for your project during initial consultations.
Our shot peening service is undertaken in-house, ensuring that Plastic Coatings retains control over costs and timescales for your project, helping to keep our service competitive without compromising on quality.
We undertake all projects to the highest quality standards and have maintained ISO9001 amongst other accreditations as a part of this.
Shot Peening Technology
Shot peening is a cold working process, in which the surfaces of components are subjected to substantial impact from small spherical pieces of media called shot. Each individual ball of shot acts as a tiny peening hammer, creating small indentations or dimples on the surface. This causes plastic deformation in a shallow layer of the component. When the indentations in the surface overlap, the fatigue life of the component is greatly increased.
Plastic Coatings uses the Almen Arc method of measurement for validating the process, ensuring intensity control and repeatability across the operation for improved component quality.
Plastic Coatings can further offer a variety of shot to perfect the treatment of your components.
In the spring and gear manufacturing industries, shot peening is used extensively where the benefits of the process are used predominantly to enhance product longevity.
Working
with PCL
Plastic Coatings has specialised in a comprehensive coating service, including pretreatments such as shot peening, since our establishment in 1952. Our extensive experience and knowledge ensure we can provide a leading pretreatment service for a wide range of industries.
Our shot peening operations are complemented by a variety of additional pretreatments. Our tailored approach to your project means whether you require an isolated service or a full coating system, we can help.
Benefits
of Shot Peening
Increased fatigue life
Increased corrosion fatigue resistance
Increased stress corrosion cracking resistance (SCC resistance)
Increased surface hardness caused by the cold working effect of shot peening
Increased surface roughness of shot peened parts allows for better adhesion of subsequent coatings that may be applied (if required)
