Heat Treatment: Ensuring high spring quality

In this blog post, we look at the use of heat treatment in spring manufacturing to optimise quality. The quality of any product is directly and heavily impacted by the procedures carried out during its production. There are a range of processes and practices which can be implemented to ensure the highest quality of manufacture is achieved, with heat treatment being one of these. The effect of temperature on initial tension and elastic limit of stainless steel [...]

Prestressing: Ensuring high spring quality

Prestressing is a quality-improving process often implemented during the manufacture of springs – mainly compression springs – to enhance their mechanical properties and improve their fatigue life (life cycle). The process involves compression by loading a spring past its elastic limit until it reaches a solid position or a predetermined length (the latter is less common) and plastic deformation occurs. This results in a number of enhancements to the spring including: Increased elastic deformation Increased load capability Improved relaxation [...]

Shot Peening: Ensuring high spring quality

In this series of blog posts, we will look at how to reduce the net stress on springs through quality manufacturing. In this post, we delve into how shot peening achieves this. This process traces back to its use in the automobile industry in the late 1920s. It is still widely used today in aerospace and automotive high performance component production. What is Shot Peening? Shot peening is the cold working process of firing spherical pellets at the surface [...]
