This is the third time that I used a waxing method to make jewelry pendants. The theme of this work is to add a silver jacket to the partner’s Yuzhu pendant. Reference to a hollow flower pestle pendant of the Croxin, enlarged and converted into a spin -available design.
The main part of the silver suit is to punch a punch to make a wax tube, and then carve the hollow patterns. First of all, the pattern must be designed. The editor is not enough. There is no art foundation. First draw the drawings by hand, print it with the line with the computer, and then slowly engraved along the lines on the wax.
Although the wax tube is not hard, it is not difficult to punch the hole, but it is also relatively crispy. You can’t directly punch with a thick drill, otherwise you will break the tube and have to gradually drill out the pipe holes from small to large, and then Push the internal thread with silk at one end.
Slowly carved the pattern along the line, the editor was stupid, and the process was extremely long. Essence Essence Essence Essence
After the main body is roughly engraved, start making the cross flower screws on the other end. I tried to attack the teeth on the wax rod directly with the tooth, but the wax tube was too loose and could not attack, so I had to find another way. Finally thought of using wax water to make a tooth pattern. First, a piece of aluminum alloy was found, and a hole that suits the size is good.
Push with the wire of the internal thread and attack the thread on the aluminum alloy.
Then put a PVC water pipe on the holes of the aluminum alloy and pour the melted wax water.
After the wax water is cooled, remove the water pipe water, and a wax tube with a tooth pattern is ready.
The basic materials are ready, and the carving of other parts will begin, and after a long process. Essence Essence Essence The whole accessories are carved.
Welded the wax mold to the wax rod and inserted into the bottom of the cast cup. This is: planting wax trees.
Enter the second stage, prepare gypsum pulp and mix well.
For the first time, vacuum.
Inject the casting cup.
The second time is vacuum.
I have experience this time. Taking advantage of the gypsum slurry, the overflowing pulp was wiped off, and the static was placed, and then I slept well. Essence Essence Essence Essence
Wake up the next day, the gypsum also solidified, removed the base, and prepared to put in the stove to bake.
After the stove is preheated to 150 degrees, the casting cup water is placed down into the furnace, so that the wax mold is hot -melt and evaporated, forming a hollow gypsum mold, this is: loss of wax.
It is another long baking process. According to the gradual heating and thermostat process of 150 degrees-300-degree-750 degrees -600 degrees, it finally keeps the molding mold at a high temperature of 600 degrees and prepares for casting.
The size of the casting this time is not small, and there are more silver materials used after calculation, so the furnace is used to melt silver to improve efficiency.
After the silver material is melted into silver water, take the casting cup out of the stove. Put the water mouth on the casting bucket of the vacuum machine, open the vacuum, then pour the silver water into the casting cup from the water mouth, and wait a while to wait a moment. You can turn off the vacuum and slowly wait for silver water to cool. This process is a high -temperature operation and is dangerous. To ensure safety, there is no distinction of photos.
After about 20 minutes of static cooling, put the casting cup in cold water and fry. The gypsum mold was naturally cracking under the action of heat up and cold, and the casting could be removed.
Finally met the casting. Although there were a lot of gypsum on it, the overall as a whole was basically intact, and the cast was successful.
Wash and wipe again, and let the gypsum in the gap in the ultrasonic cleaning instrument.
Clean the gypsum basically, and then perform the next step of repair and assembly process. At this time, the editor found that there were some small bumps on the casting and needed to be polished. This was not caused by the last cast guitar pendant. I wonder if the original wax mold surface was caused by dust or wax powder. The specific reason.
Cook the casting with alum water, cut the accessories one by one, polish the water mouth, and then carefully polish the surface and corners of the accessories.
Start the assembly accessories, wear a chain ring into the flower head, and welding a small section of silver bar on the flower head, so that the chain ring can stabilize the local card inside.
Welding the flower head to the main body, in fact, the wax mold can be welded into one when casting, but the editor does not have such a large furnace to release such a high casting cup, so I have to separate it to cast it again and again. Welded together.
The welding is completed, and the cross flower bottom is assembled to try. The overall effect is not bad. At this time, wash the welding mouth with alum water.
Do the old hair black, and then polish, the whole process is completed.
Put the jade pendant into the silver suit, and then tighten the bottom of the cross with the bottom, so that it will be made into a unique coin -bag jade pendant.
With the silver chain hand -made before, a set of privately customized retro banking jade necklace is completed.
Looking at the size, it is really big, but the little partner is also a tall, so there is basically no sense of disobedience. To sum up the whole process is really a process of constantly encountering problems to solve the problem. In poor craftsmanship, the size of the jade pendant is irregular, and it is repeatedly repaired or even redefined when the wax model is made.
