Shot blasting
What is shot blasting?
A method of cleaning the surface of metal using abrasive/blasting material. This process can remove paint, oxidation, oils and other contaminants, smooth/abrade the surface and prepare it for further processing. Cleaning metal surfaces to pure metal is an important factor to ensure a high quality subsequent surface treatment. We provide a surface preparation class of Sa 2.5 and can also offer a class Sa 3 if required.
How Shot Blasting Works
In addition to cleaning metal, shot blasting creates micro-dimpling on the surface of the metal as millions of units of shot inundate and repeatedly strike - acting like a peen hammer - to produce a uniform compression stress layer. The surface compression strengthens the overall metal, making it ready for your end-use applications.
Applications of shot blasting
Removing corrosion
A method of cleaning the surface of metal using abrasive/blasting material. This process can remove paint, oxidation, oils and other contaminants, smooth/abrade the surface and prepare it for further processing. Cleaning metal surfaces to pure metal is an important factor to ensure a high quality subsequent surface treatment.
Surface preparation
It is possible to form countless fine irregularities called "textures" on the surface of metals, resins, and other materials. By changing the size, shape, or material of the particles used, it is possible to create a variety of textures. The purpose of this textured processing is to achieve the anchor effect which improves adhesive strength, adds patterns, and improves wettability.
Paint Stripping
Shot blasting is used to remove or strip paint from the surface of the object.
One of the features of blasting is that it can do this removal regardless of the material of the workpiece, unlike chemical or heat treatments.
Increased product life cycle
By colliding spherical particles against the surface of the target metal at high speed, compressive residual stress is applied, causing work hardening and plastic deformation that is called peening.
This peening improves the wear resistance and fatigue strength of the target workpiece.
Surface smoothing/deburring
Protrusions that occur when processing metals, resins, etc., as well as those protruding from mould joints and hardened during casting, are called burrs. Burrs cause various problems such as injury during product use and deterioration of quality. Therefore, they are removed by blasting if necessary.
Even burrs in small areas that are difficult to reach can be removed by blasting, thanks to its features of constant processing force and non-directionality.
