By Axel HenselderMore from this author

State-of-the-art technology and innovative methods are the pacemakers for high-performance and effective work in a crafts trade. Jewelers and goldsmiths can draw clear benefits over the competition if they own a modern studio.

goldsmith studios

Whether they work in producing unique pieces or in repairs, specialist retailers have very special demands with regard to machines and tools: Firstly, they must be usable in very limited space. Secondly, they must also operate economically with very low unit numbers. Computer technology enables both of these options. Machines that previously were only interesting for large manufacturers are getting smaller and smaller and more efficient, while the procurement costs are falling. This opens the doors for goldsmith studios and ateliers to state-of-the-art technology. GZ Art + Design provides a summary of the latest products and methods over the next few pages.

Engraving by needle printer

The new MPX-70 needle engraving printer is probably the simplest and most inexpensive method of computer-assisted individualization. The new RPMS technology quickly engraves images, logos, lines and texts in materials such as copper, gold, silver, platinum, aluminum, stainless steel and acryl, drawing on its nine needles. Only three steps are needed for professional engraving: First of all, the digital data is imported from the camera, CD-ROM/DVD, a scanner or a mobile telephone. The supplied software can then be used to process and optimize the image. Now all that is necessary is to position the material for engraving and off we go. The jeweler or goldsmith only needs a few moments to individualize the item of jewelry just as the customer requested. www.beco-technic.com


Hand pieces, setter hammers and micro-devices

The firm Badeco from Geneva has produced high quality, reliable and high performance tools for discerning goldsmiths and watchmakers since 1945. The company is regarded as a specialist for machines and equipment relating to all aspects of drilling, milling, grinding, polishing, hammering, riveting, setting, engraving and chasing. The all-round talent Micro M3ASF is one example for the extensive tool program. Seeing as there are two heads for alternate operation, it is not constantly necessary to switch the device heads. The entire system can also be controlled using a foot pedal. An overload guard ensures safe work. Numerous exchangeable hand pieces, for example the rivet and setting hammer, engraver and such like round off the range. www.badeco-geneve.com

Multi-purpose magnifying glass for goldsmiths

The multi-purpose magnifying glass for watch makers, model builders and goldsmiths is fitted with an LED lighting option. The angle of the beam can be adjusted using a grid setting and produces a very bright, even light. The magnifying glass is ultra-light; it weighs less than eleven grams, including lighting and batteries. Two spare batteries are contained in the scope of delivery. The multi-purpose magnifying glass is only one example from the extensive program offered by the Pforzheim-based supplier Karl Fischer GmbH. The company is specialized in goldsmith tools, workshop equipment, fittings, pearls and gemstones. www.fischer-pforzheim.de

Cleaning jewelry with ultrasound

One of the new features in the range of over 14,000 products offered by DT & GoldArt for goldsmiths and jewelry retailers is the Finosonic compact ultrasound device. It presents itself as an extremely robust and high performance device for cleaning all objects in a goldsmith studio. The cleaning trough with the dimensions 140 x 11 x 55 mm offers sufficient space for the objects to be cleaned. The cleaning time can be set in five stages to between 90 and 480 seconds. The device operates extremely effectively with an ultrasound frequency of 42 kHz.

DT & GoldArt

Other new features from DT & GoldArt include the English quality rollers from the brand name Durston. The roller setting is read simply of a calibrated scale. Fitted with maintenance-free bearings and step-down gears, the high quality hand rollers can be used to process sheet metal and wire. A separate roller stand is also available for all Durston rollers. Alternatively, the rollers can also be screwed to the workbench. www.dt-goldart.com

From computer to production in hours

Castaldo introduced recently a new silicone rubber compound to make high-volume production molds directly from CAD/CAM, rapid prototyping and stereo lithography models without damage to the plastic originals. No intermediary steps are necessary with the new Castaldo® VLT ™ Jewelry Molding Rubber - customers can make a conventional production mold with this new rubber directly from their resin models.

The new Molding Rubber brings to jewelry manufacturers what has been missing from the CAD/CAM revolution - speed! Computer models can go into production in hours, not days! New Castaldo® VLT™ (very low temperature) rubber can be vulcanized at as low as 71° C/ 160° F, well below the softening point of most plastic resins and even below the softening point of traditional carving waxes. A standard sized jewelry mold with a beautiful high-shine finish in the pattern area, no loss of detail and very little shrinkage can be finished and are ready to go into high-volume production within 30 minutes, depending on the temperature used. Molds made from New Castaldo® VLT™ are tough, strong and long lasting - tough enough for multi-part molds and even molds with cores and spiral cutouts. Waxes are self-releasing - no release spray is needed because the rubber already contains silicone oil. Waxes come out with a beautiful high-shine finish which means less finishing of the final casting. Molds cut like butter and are easy to pack because the unvulcanized rubber is soft and pliable, like putty or molding. www.castaldo.com



Day and UV light from one lamp

The firm System Eickhorst from Hamburg recently presented a special edition of the silver Dialite lamp with a table joint, which can be switched from daylight to UV light, depending on the needs. The patented assembly of the upwards-facing, long-wave UV light with black glass filter as stone inlay reveals even week fluorescence, e.g. from diamonds and illuminates them with considerable contrast against the dark background of the filter and the shadow blind, which screens off the rooms light.

The daylight colors 5.500 Kelvin meet the CIBJO requirements for all gemstones and pearls. The 6.000 K, specifically designed for diamonds, can be used to the power of three and can also be controlled individually. The extremely flexible and feather light, double spring arm joint means that the Dialite DUV can be adjusted to suit any cramped assembly, irrespective of whether it is used with a table clamp, a screw connection or a heavy foot. Wobble and flicker-free operations and the quick start function mean that the silver lamp is an all-round, universal working unit for everyone involved in creating gemstones and jewelry. www.eickhorst.com

High gloss polish for precious metal alloys

Jewelry must sparkle lavishly in order to spoil the eye of the beholder. Increasing numbers of jewelry customers want to be able to clean their own jewelry in regular intervals. However, they often only polish the piece that is the current flavor of the month or that suits the outfit. So it needs to be quick and the result must be convincing. This is why particular significance is placed on the degree of fineness of the polishing material and the high gloss cloth used during high gloss polishing. The firm Hatho from Eschbach in the Breisgau region offers a fine, ammoniac-free emulsion for high gloss polishing of silver and gold alloys. Hatho Polistar Emulsion is characterized by a creamy and liquid consistency, a pleasant aroma and a fine high gloss polishing agent in a µm range. Just a few drops on a clean cotton cloth are sufficient in order to polish the prepared, scratch-free surface quickly to high gloss. Hatho Polistar Emulsion is available in handy plastic bottles containing 50 and 125 ml. This is just one of many products from the range offered by the specialist tool retailer for the watch and jewelry industry. www.hatho.de

Analysis of alloys and galvanic baths

The top model "FISCHERSCOPE X-RAY XDVSD", which was introduced by Helmut Fischer GmbH + Co. KG from Sindelfingen this spring, is particularly suited to determining the contents of fine gold and other precious metals and for the analysis of galvanic baths and minerals. The device works with power-dispersive X-ray fluorescence. This permits non-destructive, non-touch and automatic measurement. The device is easy to handle and provides meaningful results in a very short time span. The X-rays are screened in such a way in the full-protection device that no irradiation protection officer is required in the company. Up to 24 individual ratios with regard to layer thickness and element concentration can be determined at the same time in one measurement procedure on a specimen. The layer thickness of alloys can be measured down to a magnitude of 10 nanometers. In gold analyses, a repeated precision of 0.5 percent can be achieved. The results of the material analyses are precise up to 100 percent. www.helmut-fischer.com

Miracle weapon for processing prongs

Rounding off prongs and claws when setting gemstones requires precisely suited tools. Despite optimized cutting geometry of the tools, this work may indeed lead to shavings blocks and therefore to blockage of the teeth. In order to counteract this, the firm Busch has developed the hollow drill 411CCC (Clean Cut Cup Bur) In addition to the tailor made cutting geometry, the special feature of the CCC hollow is the precise Phillips tip, which promotes removal of the shavings. This means that there is no blockage of the teeth and instead smooth surfaces on the work piece. A circling approach to the work is necessary to ensure good results. The CCC hollow drill made of tool steel is available in ten different sizes or as a set. www.busch.eu



Correct fine welding is an acquired skill

The PUK fine welding devices by the firm Lampert have established themselves in many workshops, schools and production plants since their market introduction five years ago. Electrical light arc impulse welding has an important place in addition to laser and gas welding. The working manner, which is very similar to laser welding, and the comparably low investment requirements make the technology very popular among goldsmiths. Like with any modern tool, training or professional instruction are important to get the most out of using the equipment.

This is why Lampert Werktechnik GmbH offers its customers a special service not only selling the equipment, but also the know how to for uncomplicated, flexible and highly efficient welding on precious metal alloys. A free PUK newsletter, published every six to eight weeks and accessible on the Lampert website, provides users with a step by step guide as to how to weld properly. Practical tips and handling instructions - elaborated on using practical examples - turn the newsletter into a real workshop.


Perfect interchangeable clasp systems

Nittel system manufacturers the optimum interchangeable clasp system offering goldsmiths every option to realize their designs and elaborate ideas within a cost-efficient framework. The Nittel clasp consists of a spring tube is soldered or bonded invisibly in gold or stone balls, pearls or intermediate gold pieces.

Ranging in length from 5 mm to 20 in intervals of 0.5 mm, the products offer all conceivable variations. Orders are delivered inside of 24 hours, meaning that stockpiling is not necessary. All clasps and keys are supplied in 18 karat white or yellow gold, platinum, sterling silver and in stainless steel. www.nittel-system.de




Laser welders for any budget

Neutec/USA® announces its new line of laser welding machines: the PulsePoint™ Studio™, the PulsePoint Model 150 and the PulsePoint Model 200. Specially engineered to make every joule of energy work harder, the Neutec PulsePoint laser welders make laser technology available to every business - no matter what jewelry production or fabrication tasks they perform. The full-size, floor-standing PulsePoint™ Model 150 and Model 200 laser welders offer full production capabilities. Each is designed for precision production welding of nearly any metal - even on difficult-to-weld metals such as silver. These machines are designed to provide rapid cycle times with all the power needed for a vast range of assembly and repair tasks. Their advanced constant voltage power supply eliminates power spikes to deliver smooth, consistent power. On the Model 200, settings for finer spot size are ideal for extra-fine detail work such as filigree and stone mountings, and provide extra versatility in weld depth for curved surfaces or heavy pieces.

At a much lower cost than larger machines, the compact, tabletop PulsePoint™ Studio™ delivers high-quality laser welding - a benefit for almost any budget. The Studio plugs into any power supply, needs only 16-1/8″ x 15″ of workspace and weighs less than 60 pounds, yet its 30W average power output easily handles production, repair, assembly and fabrication needs with professional results - an excellent choice for working with chain. It's easy to move and set up, easy to use, and easy to maintain. www.neutec.com

Wellness at a goldsmith's place of work

There is no doubt that a workshop is not the place for relaxing massages or spa packages. Nevertheless, there should be minimum standards of wellbeing in the course of everyday work. After all, we all spend a lot of time at work. However, it is frequently the case that a goldsmith's work surface does not even satisfy the simplest standards of ergonomic requirements. The firm Paul Peter Schula from Lübeck offers special work tables made of wood and steel that really bring out the fun in work.

In addition, Schula is a competent partner for all questions relating to workshop equipment. Two different types of bench filing pin systems are examples of the company's performance. The working height of one of the systems can be varied between 0 and 200 mm. Within this framework, the solid steel construction ensures high stability and resistance to vibration, which are important factors when sawing and filing. An alternative is the innovative bench filing pin system from the well-known gold and silversmith Hansjörg Fritsche. The double design of the bench filing pin means that the system is suitable for left and right-handed people and can be turned and locked in any desired horizontal position. Additionally, the double bench filing pin is also designed as a dovetail, which significantly simplifies sawing work. The supplied intermediate block means that workplaces that are too low can be raised by around 40 mm. www.schula.de

Multicolored jewelry: together forever

Particularly in the design of wedding rings latest trends show that there is an increasing demand for new, fancy designs. Multicolored designs consisting of various mixed materials are en vogue. Schultheiss took care about this direction of the market and offers the appropriate production technology.

For more than two decades now, Schultheiss is developing and producing induction melting systems, pressure over vacuum casting systems, granulating systems and continuous casting systems. A couple of years ago the development of new possibilities in the field of high temperature casting was achieved. As for casting platinum jewelry parts or manufacturing industrial stainless steel prototypes the machines work not only by gravity or pressure over vacuum, additionally a centrifugal force is applied to achieve optimal casting conditions. In the area connecting two different parts together, Schultheiss has started with inductive soldering including ring soldering units. Subsequently, when the demand of the industry increased and soldering reached its limitations, Schultheiss developed the diffusion bonding technology, to join metals of different materials and colors - the sintering machines. The basic idea was to be able to connect seamless different metals (gold of different colors, but also with platinum, steel or even titanium) without the help of additional solders or brazing alloys.

The sintering process - also known as diffusion bonding - takes place under vacuum and pressure. After the parts to be connected have been positioned and placed into the die of the machine, the system is heated up by a powerful induction heating. The control guarantees a fast heating at the lower temperatures and a precise movement to the desired final set point. Once this temperature, where the bonding itself takes place, is reached, a high mechanical pressure is applied to the parts. Staying under certain - perfectly monitored and controlled conditions - the materials will be diffused and bonded to each other. The new produced boundary surface with a thickness of a couple of µm belongs to both of the materials and therefore assures a stable and lasting connection even under mechanical stress or high temperature changes. Since it is a fusion between the combined metals the sintered connection is practically unbreakable. The parts can be further processed mechanically by rolling, stretching, machining and also multiple sintering processes, without the risk of breaking the connection. www.schultheiss-gmbh.de




Specialist for surface processing

For ten years now, the firm Otec has operated successfully on the markets around the world with machines for surface processing. Since it was founded by Helmut Gegenheimer, the number of employees has risen to 35.

CNC revolution

Watchmakers as well as the jewelry industry generally produce all the components of their own chronograph creations themselves. The high degree of verticality in production and pressure to lower costs demand new production techniques. The problem is that industrial CNC machines are too large and expensive for most parts made in this sector. Smaller, less expensive, but still highly precise CNC machine tools are needed; and that is exactly what watchmakers and jewelers are finding at Austria's largest machine tools manufacturer, Emco. Emco offers table-top CNC lathes and milling machines. These little wonders boast all the features and functions of modern industrial CNC machines enabling the user to manufacture the required parts quickly, economically and with incredible precision. One of the factors in the success of Emco technology is its ease of use. A PC controls the machine. We have kept the software simple for ease of use, enables the operator to work the machine without any prior CNC-programming knowledge. www.emco.at



Greater efficiency at work with laser welding

The new desktop device Powerlaser from the firm J. Schmalz enables smaller companies to get a foothold in the progressive technology of laser welding.

The right solution for every cast

Indutherm turned ten years old just a few days ago. A young team of highly gifted engineers founded the firm in 1996, specialized in casting machines. The company's casting machine, the VC 500, immediately set new standards and was welcomed by the customers with open arms. Slightly later, the VC 400 was added to the program (the smaller brother to the VC 500), soon followed by the VC 600, a program-controlled, automatic machine. This therefore covered almost the entire range of jewelry production. All that was missing was a range of very large machines for industrial applications and the connecting link to the design studio, the MC 15. This MC 15 has kicked up a veritable storm in recent times, as this compact desktop machine can also cast steel and platinum - a great option at a moderate prize.

Right from the start, the machines were constructed to be very user friendly. State of the art technology remains decently in the background, while users are supported and not confounded. Instruction is fast and does not require any computer skills. As time passed, the machines have of course been consistently developed. For example, a D type of the VC 500 has been produced, in which all of the casting parameters can be saved and printed out: This means that the casting parameters for difficult cast parts can be accessed even after a long period; additionally, all data can be analyzed in the event of any problems relating to casting. An innovative vibration technology was introduced in the VC 600, which has favorable effects on the form filling and metal structure. For this innovation, Indutherm has received the globally coveted MJSA Technology Innovation Award 2006. www.indutherm.de

Polymer ceramics add color to jewelry design

Material, form and color have always been close auxiliaries when it is a question of fashioning high quality, creative jewelry objects. Colors especially leave unmistakable traces, provide identity or trigger emotions and passion. In Novorit, the company Heimerle + Meule has offered since this spring a system for high quality color creations. It draws on a recently developed polymer ceramic material. And it offers entirely new design options for jewelry designers and manufacturers. Polymer ceramics represent a new generation of materials. Using a multi-stage manufacturing process, methacrylate is combined with finely ground ceramics. Defined color pigments are added in the process. The result is a new compound material with over 55 percent contents of high quality ceramics. In five standardized stages of work, jewelry designers and manufacturers can achieve a constant and high level of quality and efficient processing, even when dealing with large unit numbers.

The new Novorit method means that all color accents can be realized in just one layer. Every desired material layer thickness can be applied in any chosen color and then hardened. This is connected with significant time savings in production compared with all previous methods. The new polymer ceramics can be used to create extremely hard and resistant surfaces. After deep hardening, they are entirely homogeneous and free of bubbles. Nevertheless, they can be ground simply and quickly and can be polished matt or to high gloss. The polymer ceramics can also be processed and designed using lasers. For example, this may create multicolor, integrated color patterns or even three-dimensional effects.

Novorit polymer ceramics are available in a large selection of standard colors. There is also the option of developing individual, customer- specific colors on the basis of Pantone color standards. And in order to ensure that Novorit design pastes can be processed according to the individual circumstances of the company manufacturing the jewelry, Heimerle + Meule offers the complete engineering, supplies tailor made processing packages and also looks after the instruction of the future users. www.heimerle-meule.com

More than just a precious metal refining center

When Eugen Dürrwächter founded Doduco (Doktor Duerrwächter Company) in Pforzheim, Germany in 1922, it only started as a small refining center. It was taken over by the American Technitrol in 1996 and became AMI DODUCO so that today it is a major player on the international scene.

It has a wide range of diverse products and services including locations in Europe, Asia and North America. It focuses on manufacturing products for electroplating, precious metal coating and precious metal recovery. The high-profile precious metal separating center of Ami Doduco guarantees fast and economical processing of all recoverables containing precious metal based both on time-honored and next-generation technologies. Armin Nittel, the sales manager of the precious metal separating center sees in recycling "something that will be necessary for a long time to come" since gold mining is becoming increasingly complex, resources increasingly scarce and environmental protection increasingly important. www.amidoduco.com

The multi-cell soldering equipment

The Spirflame® electrolysis soldering equipment from Spirig is patented all over the world. In contrast to the known hydrogen soldering equipment, it has a unique technology of twenty (and more) electrolysis cells making it genuine multi-cell soldering equipment. You benefit from this technology with low heat loss and even heat dissipation. The multi-cell technology creates flexible, high-performance and very reliable welding equipment for use with one or several burners and clean process gases for long-term use in industry. A good example is filigree gold wire work from Giovanni Corvaja (Italy) that requires a calm hand and even and constant heat development on the finest flames. Spirflame® is the first soldering equipment that allows you to do this work well. The KARAT® models have a two-year guarantee. www.spirig.comwww.karat250.com

From the label to the inventory

"Our software is not a merchandise information system" emphasizes Alex Schickel, CEO at Ferdinand Eisele GmbH, forcefully. But the label specialist's program is good for more than printing tags. "Extra4 is a modular building block system," he explains with regard to the software structure, "and this gives users untold opportunities." As a label manufacturer, they know precisely what is important when printing data on to a label and to make it useful for other options as well.

With Type'n Print, the simplest level of the program, the user simply types in the label texts in a prepared window, issues the print command and the label is finished. Store'n Print enables the user to save items that recur regularly using the installed label database, to call them up individually by item number or to print them out in stack processing. In addition to the labels themselves, texts or any length and also images can be stored. Lists of the saved items can also be printed out. There is a large number of prefabricated layouts available for all standard label forms. The customer selects a layout to suit the label and then fills the input window with text.

Certain modules expand the potential of the basic version for experienced users. These plug-ins enable access to external desktop databases such as MS Excel, MS Access, dbase and many others, along with client/server databases such as Microsoft SQL, Borland Interbase and so forth. The module Calc can read data from connected gold scales and convert it into individual label texts.

Particularly ambitious users can also upgrade the label printing program using the inventory module provided by the firm Comcept from Cologne and therefore use it for simple inventory or even for the merchandise information system CCJewel, without having to recreate data that have already been saved. www.ferdrnand-eisele.com
