VCC for Platinum has been designed with the special qualities of the metal in mind. Platinum is renowned
for its high melting point and the fact that it solidifies fast. During casting it is vital that the molten
metal is poured accurately, quickly and smoothly into the mould. To achieve this Yasui has developed the
'Double Swing Arm' this ensures that the mould and molten metal are precisely aligned in the same axis.
Precise servomotor control then allows the metal to be fully transferred into the mould in a 1 to 1.5 turn.
These advances overcome the problems associated with traditional straight arm casting machines where
strong angular acceleration and centrifugal forces are exerted on the molten metal. On rotation, this can
cause the molten metal to miss the mould and splash to outside of the flask.
On the Yasui system there are further enhancements in the form of highly accurate thermal control and
selectable casting atmosphere. The ideal atmosphere can be chosen from vacuum, air, inert gas presence or a
mix of both vacuum and inert gas.
Finishing Techniques have recently supplied a VCC for Platinum to Weston Beamor, the Birmingham based
pioneer in the design and casting of jewellery.
Firescan, an all in one laser engraving system, is being introduced to
UK jewellery manufacturers by the leading industry supplier, Finishing Techniques. Individuality is the
name of the game. Customers want jewellery that says something about them or records an event of importance
to them such that it is timeless like the piece that carries the message.
Now Firescan will give the jewellery industry a flexible laser system that is safe to use on a desktop.
The ultra-precise 0.2mm laser beam is controlled from a standard PC running easy to use software that is
supplied with the unit. Perfect engraving and inscriptions can be made on single pieces or batch production
of jewellery and giftware. Signatures, graphics, logos, photos and more are reproduced flawlessly every
time at resolutions up to 1000dpi.
Precious metals and even plastics are easy to etch using Firescan. Deep engraving and intricate designs
can be performed on flat or curved surfaces without the need for extensive training. Furthermore, all
markings are permanent, chemical proof and abrasion proof.
Unlike many other systems, Firescan is completely air cooled so there is no need for a water connection.
This contributes to low running costs and makes the unit more compact and convenient to locate wherever
there is a standard power point.
Firescan is one of a range of quality laser engraving and welding machines made by Siro Lasertech of
Germany and available in the UK solely through Finishing Techniques. Product details are available from the
company on 01706 825819.

RECYCLING AND WASTE WATER SOLUTION
FOR JEWELLERY PRODUCERS
A simple solution to recycling deburring and polishing fluids and
waste water, while concentrating pollutants for disposal, is now available from Finishing Techniques. The
WasteWizard uses a patented polymer membrane, that never clogs, to filter out and collect soils that reduce
the useful life of most fluids. The unit is ideal for use in deburring, polishing and other jewellery
production processes.
Significant savings in chemical costs are promised as WasteWizard re-purifies for reuse up to 85 per
cent. This ensures the unit achieves a quick payback. The unit concentrates waste by up to 99 per cent so
less bulk means the cost of collection is reduced. Cleaned water is made safe for disposal down the drain
or can re-enter the manufacturing process to save water charges.
WasteWizard is designed to fit a standard 200 litre drum or for lower volume needs of smaller jewellery
producers, the company produces the MiniWizard which provides the same benefits but sits on a 60 litre
drum. Filters can be stacked to provide greater processing capacity. A single stack will filter 16 litres
of fluid per hour rising to 80 litres for the five stack unit. A built-in cleaning cycle ensures the
clog-free membranes last from 12 to 18 months.
A major benefit for the jeweller manufacturing process is the recovery of precious metals from the waste
water. WasteWizard provides a fast and efficient method of producing a concentrated sludge that can be
refined to recover gold and other precious metals more easily. This is much quicker and more effective than
using settling tanks.
Finishing Techniques managing director, Jonathan Dean, explained, "WasteWizard brings more than
just cost benefits through waste reduction and recycling. It improves the manufacturing process by removing
contaminants that harm finished product quality. Another saving made by reducing rejection rates."
Purchase or rental packages are available. For free advice on the correct WasteWizard configuration the
company can be contacted on 01706 825819.
