Stainless Steel Shots

Application of Stainless Steel Shots in Shot Blasting:

Shot blasting is a surface treatment process commonly used on aluminium extrusions to prepare them for further finishing or to improve their appearance and durability. It involves propelling abrasive media at high velocity onto the aluminium surface, effectively removing imperfections, creating a uniform texture and enhancing adhesion for subsequent coatings like paint or anodizing.

 

Purpose of Shot Blasting:

Surface Preparation:

Shot blasting removes surface imperfections such as die lines, scratches and oxidation, creating a clean and consistent surface for further processing.

Adhesion Enhancement:

By creating a textured surface, shot blasting improves the adhesion of coatings like paint, powder coating or anodizing.

Aesthetic Improvement:

It can create a desired matte or satin finish, enhancing the visual appeal of the aluminium extrusion.

Corrosion Resistance:

Shot blasting can improve the corrosion resistance of the aluminium by removing surface contaminants and creating a more uniform surface.

Stress Relief:

The process can also relieve some surface stress in the aluminium, potentially improving its long-term performance.
