Finishing and Surface Treatments

 

Hajm steel  routinely provides a wide range of metal finishing and surface treatments to its cast products in order to enhance their mechanical or aesthetic properties.

Once the component surface preparation, usually in the form of fettling, linishing and shot blasting is complete, surface treatments and finishes are applied and these can include heat treatment, anodising or painting.

Fettling & Linishing

 

These are the first processes usually performed on raw sand and die-cast components. Fettling removes the risers and excess material while linishing is the process of grinding or sanding the surface to remove surface irregularities.

Shot Blasting & Peening

 

Shot blasting is used to create a uniform surface finish by removing surface burrs or debris remaining from the casting process. Shot peening is a similar but less aggressive process where finer particles are blasted at the surface thus avoiding the risk of surface cracking in some alloys. These processes provide an excellent key for further surface finishes.

Painting & Powder Coating

 

Castings can be finished according to customer specification, with wet painting being the most common.

Surface Treatments

 

Hajm steel  can provide any form of surface treatment required including sulphuric or chromic anodising, for enhanced durability and corrosion resistance.

Heat Treatment

 

Castings can be subjected to various heat treatment techniques that can be used to harden them, change the properties of the alloy or remove internal stresses. Hajm steel  is able to advise on the options and deliver castings that are optimised for their operating environment.
