QUICK - CAST 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.
MAX WAX RED 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.
MAX WAX BLUE 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.
MAX WAX GREEN 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.

Castin 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
CASTIN - YELLOW 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.
