Knead able Soldering Mass
In comparison to hard soldering blocks, Quick - Cast allows the piece to be soldered to be pushed into every conceivable position imagined. Solder remains in place, thin fragile wires can be covered with Quick - Cast so they don't melt. Soldering To solder several pieces with different levels together, its now possible to solder, without tedious preparation. The pieces are placed into Quick - Cast exactly as they should be soldered. Height differences are evened out with the workable mass, after everything is ready , a flame is passed over the mass which then turns black and hard. Flux and solder can be placed onto the pieces and soldered without wobbling. Complex as well as simple soldering jobs can be taken care of in a matter of minutes. After soldering Quick - Cast can be removed by either brushing or knocking off.


Quick - Cast
Casting in just 30 seconds.
Melting. The casting mass withstands temperatures up to 1600° C, so one can easily form a crucible for smelting, this is so well insulated that gold and silver can be melted even with a weak flame. Fluid Forming or express casting, is a specialty of

Quick - Cast . A form design is pressed or scratched into Quick - Cast, e.g.. wire, sheet-metal, mountings, or a model that you need to cast quickly. As much metal as needed is placed into a shallow hollow next to the impression, (this functions even under 5g metal). With the soldering flame, go across the impression briefly, then melt the metal and while it is fluid press it with a stamp (made out of Quick-Cast pressed in the plastic box) into the mold. In seconds a cast object is obtained, with minimal metal and a fraction of the usual time consuming casting operations. Your fantasy sets no limits to the used of Quick - Cast.

Max - Wax
Rational manufacturing of jewelry using wax models.
With a little practice, the goldsmith can produce settings and other jewelry pieces from different waxes in a fraction of the usual work time. For the fabrication of tube, pave, crown settings, sawing in wax needs approx. one fifth of the time. NO MATERIAL WASTE The tasks are carried out with spiral saw, scalpel, single cut files, single cut burs, lathe and wax knives. Material waste can be melted and reused without problem, excess material can easily be melted away with the aid of wax tools. Rough surfaces can with little effort be smoothed and edges rounded with benzene or alcohol. Should several models need to be cast, a silicon form can be make directly from the wax model. After casting, a perfect reproduction is obtained, requiring only minimal polishing. The result is a trinket without solder joints, minimum gold usage and in excellent quality. Besides tools and goldsmith experience, the correct wax material is needed.


An extremely fine flowing injection wax for filigree items. With this wax it is possible to produce lightweight items at a very reasonable price. The wax has an unusual further feature, according the the temperature the properties of this wax change.

1. Under 20øC it is hard.

2. At approx. 25øC it is elastic with a memory effect, returning to its original form.

3. Between 30 - 35øC it is plastically form able without breaking. The new form remains even after cooling to around 25øC.


Unbreakable, Greatest resilience and elasticity. For carving, filing, drilling from the heaviest signet ring to the finest setting with mechanics. For producing models in the shortest possible time or for building up and modifying existing cast objects.

Highly flexible all-round injection wax with release agents. Besides excellent injection properties, sharp edges and perfect form, it offers the possibility of modifying existing models by wax build up. Its also perfect application for

MAX WAX Technical Data
The memory effect by MAX WAX RED and profile remains by temperatures under 30øC . From 35øC (body temp.) MAX WAX profile is easy to bend, wire can be drawn , jump rings twisted and even knotted without breaking. A heat adjustable wax tool or a warmed scalpel allows the parts to be connected on cooling the parts remain in their new shape. These attributes can be used to your advantage, new forms can be created by warming in the hand or under a lamp - after cooling the new form can be worked anew.

MAX WAX PROFILE By 45øC MAX WAX can be pressed into profiles. The profiles offer solid's without becoming tacky on the surface allowing easy and light working of the wax.

By hand warming these profiles can be bent and with a wax knife soldered together. This is done in a fraction of the time it takes to work in metal.

Injection Properties
Extremely far flowing, renders itself for extremely fine and filigree pieces. Now improved so that the cooling process can be slowed down. Capable of flowing further into thinner forms. New is also the strong memory effect. Models that on removing from the rubber have bent, will automatically return to their original form in circa 10 minutes. Now one has a reliable all round wax for the highest expectations.

Recommended Temperatures.

70øC - 80øC

For signet rings, band rings 65øC - 70øC

MAX WAX flows further than other wax, so it is perfect to use for thin and fragile pieces. For larger and heavier pieces, the pressure can be reduced so as not to distort the rubber form, (reduce up to 80%)

Pressure e.g..

Signet ring 0,2 at

Claw setting 0,3 at

0,2 sheet metal 0,6 at

With usual jewelry wax one needs 100 - 400 % higher pressure and with unfavorable cooling conditions. MAX WAX remains in form and gives a more uniform result.

Plastic Properties.
Between 18 - 24øC MAX WAX is firm and elastic Compared was the penetration of a needle to DIN 51 579 The higher the number the stronger the irreversible deformation. Form comparison Through the elasticity even bent pieces return back alone. Sold in Kilo or in Blocks and as thin sheets. MAX WAX saves material by producing models of better quality.

1 Kilo MAX WAX yields approx. 11 kilo silver and 15 kilo 585 gold castings.
Around 2500 pieces can be produced, when only 1 minute polishing time can be saved per piece (usually its much more), then at least 800.00 DM /per 1 kilo wax, can be saved at a hourly salary of 20.00 DM .
MAX WAX is a synthetic wax (thermoplastic) for models produced by the lost wax casting method. It burns at 500øC without residue.


for production of high quality precision castings. Castin is a fluid which is used instead of water to mix all the usual investments, (Kerr, Hopin-Davis, Randolph etc.,). In comparison to water Castin has also the following qualities.


Reducing Results
With Castin the investment glazes on contact with the molten mass, giving air no access to the casting and therefore stalling the oxidation process. With the correct casting temperature a shiny oxide-free result is achieved.

Sometimes this effect can be seen as a light red copper tone on the surface dependent upon alloy used. Structures smaller than 1/1000 mm are eliminated by the surface tension of the glaze, so polishing becomes much easier. Through Castin, casting with stones in place (diamonds, sapphires, garnet etc.,) can be achieved without oxidation on the contact surface. Generally one can eliminate cleaning baths or bead blasting after using Castin, this represents not only a cost saving but increases the quality of the metal surface.

Diffusion gets more
Castin works by finely netting, but with greater part differential hardening. 15% less investment is needed to fill the same amount of flasks, additionally the firmness is improved. With greater volume and evenly spaced cavities, the air resistance is lessened reducing consequently metal resistance on casting.

With quicker filling, a more uniform tree is obtained whereby thin and fragile parts cast out, these usually not being successful in the normal casting process.

With Castin the temperature of the metal can be reduced giving a metallurgical better result. The metal can flow quicker into the form by all types of castings, spin, pressure and vacuum. The metal flows further and more uniform in the complete form. Therefore two advantages are obtained:


a: The castings are more compact and uniform.

b: Thin and fragile parts, eyeglass frames, watch bezels can be cast successfully. High quality filigree castings are now possible with Castin.

1. No surface skin, and easier workable metal.

2. Casting with precious stones in place without "sorrow ring"

3. Filigree casting without alloy overheating.


Surface Activation
Investment containing Cristoballite is a natural product, difference in grain size occur naturally thereby making a less uniform paste when mixed with water.. Sometimes ugly elevations appear underneath larger objects which have to be filed.

Castin contains fine ingredients that improve the cristoballite granules. Castin helps the investment to adhere to the model eliminating water spots and balls on the object.


Retarding Properties
Castin green and blue lengthens the potting time for several minutes so mixing, evacuating and pouring can be take care of more thoroughly. For large trees and small vacuum machines.


Castin Red
Potting time as long as the usual mixing time with water, ideal for normal use.

Castin Green
Slightly longer potting time.

Castin Blue Retard
For lengthy potting time, especially for investing without vacuum and vibrator.

For spin casting with high casting pressure, we recommend thinning down, one part Castin per two parts water. The reducing properties are still effective and the metal flows slower into the flask, this can reduce the risk of metal tearing. The suitable mixing measures are: 1 kg Investment + 0,44L thinned fluid.

Regular mixing Measures. Two measures investment to one measure Castin. (1 Kg powder + 0,5L Castin)

Mixing Before removing liquid, always shake before use, so the liquid is fully mixed.

Hardening Time
Castin Red 20 min
Castin Green 30 min
Castin Blue 50 min
After which the flask can be placed in the oven.

Heating Time

Exactly as without Castin, certain waiting times at critical temperatures should be observed. In the seminar, the optimal, quickest possible cycles are discussed.

Burning Out

Generally shorter than usual but in any case until no soot in the sprue is to be seen.

Cooling Time

Maximum 250 Degrees / per hour till the required casting temperature is reached.

Casting Temperature.

200 Degrees Centigrade for thick and heavy pieces
400 Degrees Centigrade for normal objects
600 Degrees Centigrade for filigree items



for Platinum
Castin - Yellow is ideal for mixing with phosphate bound investment. All metal, Platinum, Chrome, Cobalt, Titanium and Steel can now be cast in Castin quality.
Castin - Yellow has strong reducing properties

Castin - Yellow now makes possible the further flowing of metal into the tree, making larger trees more economical.

Castin - Yellow makes the clean up work from the flask easier, no more milling away.

Castin - Yellow gives a thinner flowing fluid during investing, makes for easier vacuuming, balling on the surface belongs to the past. Phosphate bound cristoballite investment is mixed 1 kg investment to 0.5 Liter Castin Yellow. Small flasks should be stirred to start the binding reaction or placed in a warm place.

1. Better surface quality and easier to work.
2. Filigree items in Platinum now possible.
3. Rationalization of Platinum casting with larger trees.
