Wet blasting machine

Blasting (shot, sand & glass bead)
dry or wet blasting

Vapormatt have now become market leaders in replacing existing highly toxic and expensive chemical cleaning methods, commonly used in the Jewellery trade, with their wet blast process.

Following investment casting, the jewellery “trees” leave the mould with a heavy black oxide coating and investment powder residues, which are currently removed by water blasting and chemical soaking, being a lengthy, expensive process and which is environmentally unacceptable.

(Above). Lost Wax Casting Trees.
The Vapormatt process replaces this with a “one stop” method, namely; wet blasting - at low pressure with a fine glass bead as the media. All traces of tarnish, discolouration and investment are removed, leaving an excellent surface finish prepared for subsequent polishing. One of the major advantages is that there is no measurable removal of material from the surface even though burrs are smoothed.

The system itself is totally non-toxic to install, (for example, the used water is clean enough to flow to usual drainage), and very user friendly.

Conventional pattern waxes are hydrophobic – they resist wetting – and create surfaces that are difficult for bonding. To overcome this property, investment casters wash, scrub, dip, rinse and use aggressive etches to prepare the wax surface for shelling.

The Investment Casting Process
After de-waxing a concern to investment casters is the residue left in the shell before preheat, and ash remaining in the shell after preheat and burnout. But the new pattern compound, due to the high amounts of water, is low ash filler, resulting in an improved cleanliness of shells after de-waxing.

Casting Cut Off and Clean-Up[ Click for image ]
The individual castings are removed (cut-off) from the cluster (tree). Remaining protrusions left by gates or runners, are removed by grinding. Generally the castings are shot, sand or bead blasted for a smoother finish.

Blasting (shot, sand & glass bead)

Glass Bead: A spherical, glass particle multi-purpose abrasive which produces a smooth, bright, uniform matte/ satin finish. Glass Bead cleans surfaces of chemical impurities, peens and stress relieves for improved strength, fatigue life and wear qualities, blends surface marks, removes burrs, hones and burnishes without altering dimensions, removes glare from finish, reduces porosity, reduces susceptibility to corrosion, reduces part to part friction, improves lubrication between parts and is inert and will not contaminate parts. Primarily used in such applications as:
