Wax setting ฝังพลอยในเทียน 3

WAX INJECTION

It should be possible to use most types of wax for stone in wax setting. Much is dependent on ambient temperature inside the work shop.

It is however necessary for the wax to have a certain elasticity to allow the stones to really “click” into place. SRS recommends theSRS 003 Pink wax.

Inspect all wax patterns for signs of defects or blemishes that will translate into the metal in the final product.With the time that is invested into making a master for stone in work it is well worth additional time on the front end of the process to insure that the end cast result is of the highest quality.Clean and smooth all wax patterns in preparation for the stone setting into the wax.As a general practice, all waxes that are injected in a day should be used the same day.Wax patterns that set over night can become brittle and break when the stone is clicked into the stone seat.Freshly injected wax patterns should be allowed to set and normalize for several hours, if a stone is set into a warm newly injected wax this could result in distortion of the wax pattern and a poorly fitting seat for the stone in the wax. * When setting stones into wax patterns do not set stones over wax flashing or any defects, when eventually replaced by metal this can result in stone breakage or damage.CLICKSET™ masters are designed to not need any special tools for imbedding the stones to be set into the wax patterns. Stones should click into place on the back set models and snap down evenly on the prong style models and channel sets.If for some reason a hot wax tools is needed to repair the wax be careful not cause a wax film on the back of the stone.Stones that look dark after casting are usually the result of a thin film of metal on the back of the stone where wax was inadvertently deposited.Prong set CLICKSET™ masters should have all of the prongs smoothed and finished in the master model portion of the process so that when a stone is clicked into the prong seats in the wax pattern it should fit snugly and there should be no need for any additional work to the prongs or prong tipsBack set CLICKSET™ masters should have sufficient metal on the bezel top to hold the overall stone table and girdle in place. Stones back set into place in the wax pattern should fit smugly and the table portion of the stones should be evenly displayed from the top of the wax pattern. The small specially engineered nibs inside of the wax pattern on Clickset mountings should hold the stone level and securely.
SETTING STONES INTO THE CLICKSET MASTER WAX PATTERNS:

Once the wax pattern has normalized to room temperature and passed a quality check, place the right size stone into the pattern and using a flat smooth surface for prong set stones, press the stone into the wax prongs.

It should snap into place and seat level in the wax.

For setting the back set CLICKSET™ wax patterns, turn the pattern so that the backside of the mounting is facing toward you and rest the top of the mounting on a smooth even surface, place the stone in the back of the wax pattern and using a pointed tool gently press on the pavilion of the stone till it clicks into the wax seat.

It may be necessary to press on several locations on the back of the stone to insure that it is seated under each of the wax nibs inside of the back set CLICKSET™ model.

Cold setting of stones is the preferred method of setting for CLICKSET™ patterns; hot wax pens are not needed for this process. When setting channel set stones into CLICKSET™ models be sure that stones do not touch at the girdle or overlap in the channel, as either of these problems can cause stone breakage when they are cast except as noted before.
