Vapour Honing Basics

This mechanical finish also goes by the names Silk Etch, Vapour Blasting, Slurry Blasting, Aqua Blasting and Wet Blasting. It is a mild blasting process where a slurry of water and an abrasive, pressure boosted by air, is pumped through specially designed equipment. Subject to the selection of abrasive and the pressures involved, the finish can range from semi-bright to matt. The use of water in this process gives a smoother finish than that obtained by the traditional dry blasting method.

As the slurry is constantly being recycled, it gives us the ability to add chemicals to the mix, which can degrease or chemically treat the components during the blasting cycle.

Applications for this finish range from surface finishing and smoothing edges to a pre-treatment process for under anodising or E-coating finishes. It will also remove burrs and mill scale.

The vapour blasting process is free from any toxic chemicals, making it uniquely suitable for components that are used in the medical and pharmaceutical industry.

Vapour Honing

Vapour honing is the process of using a ‘slurry’ of abrasive material carried in water, applied to components through thin nozzles under high pressure, to finish the component’s surface.

More on Vapour Honing

Thickness: Vapour honing components show very little metal removed (subject to abrasive selected).

Uniformity: Subject to the part’s dimensions.

Hardness: The process can increase surface hardness due to the inherent peening action.

Gloss: Coatings are for industrial use and tend to be a semi-gloss or metallic finish.

Toxicity: Vapour honing is approved for food contact.

Corrosion Resistance: Vapour honing can remove surface contamination that may affect corrosion resistance.

Hydrogen Embrittlement: No hydrogen embrittlement on high strength steels. The blasting action may stress relieve parts.

Cost: Unless there are large volumes that justify automated equipment, the process is rather labour intensive and is charged accordingly. Please contact us to find out more.

Size limitations: Generally this process is suited to smaller parts.

Distortion: Being a blasting process, there a limits on metal thickness as distortion may occur on thinner materials.

Recommended Uses

Vapour honing plays an important role in producing quality finishes on most metal parts. It removes sharp edges and cleans to a very high standard, making it well suited to medical industry components. It also completely removes mill scale.

Before we process any work, we always provide a specification or a service requirement for the vapour honing so we can ensure our process meets all your needs, no matter how great or small.
