We need prepare the wax mold tree that we already have.If you want to know how to make the wax mold tree,you can read my another article.
Casting gypsum powder is mainly used in casting stainless steel, platinum, palladium, gold, silver, beryllium copper and silver jewelry casting. Gypsum mold high temperature resistance, can withstand 800℃ high temperature, mold is not easy to crack, effectively reduce the loss of precious metals.
What proportion
1) Measure 1000 grams of gypsum powder
2) Measure water 380-400 ml (water temperature is required to be around 22℃)
3) Put the water into the container and add the plaster powder
4) Blend for 3.5 to 4 minutes
5) Pour into the steel cup, and then vacuum for 1.5 to 2 minutes
6) Let it sit flat for 60-120 minutes
We need pour the mix gypsum power into the container with wax mold tree,in this process we need protect ourselves.
When we pour the mix gypsum power into the container and the air also into it ,we all know the air will lead to a lot of holes,so we need to vacuum treatment.
After a period of vacuum treatment, we observed that the gypsum powder had solidified. At this time, we needed to remove the container and take out the yellow tape on it.
Sintering:
1) The room temperature must be 120 minutes to 180 ° C, 150 minutes from 180 ° C to 270 ° C, and 150 minutes to maintain 270 ° C
2) The average heating time from 270℃ to 730℃ is 150 minutes
3) Keep at 730℃ for 180 minutes
4) Then drop back to about 630 ° C and start casting.
We need to prepare gold raw materials, and these gold raw materials are recycled, and we need to adhere to sustainable development.
There are many high-temperature equipment used to melt gold, such as: gold furnace, electric furnace, furnace, gold spray gun and gas gun, we can choose the equipment we are familiar with to melt gold.When we operate, we must pay attention to safety and take good safety measures
We use tongs to take a container of cast gypsum powder out of a hot oven, place it on a special device, and then we begin to pour the melted gold into the container, as we come into contact with hot objects, we must take safety measures. Our factory is now operated by machines to avoid human harm.
After waiting for a period of time, take out the container for cooling treatment
The wax mold is heated to (850 — 1200 degrees) through a quartz crucible. The molten liquid gold is inverted to present a single ingredient suitable for processing gold ornaments.
Cut off all the arms of the ring and all the arms of the bracelet. Because of all the components, the bracelet arm is the most stressed and worn area. After the inverted mold, the density of gold is not enough. It needs to be forged by a senior technician for a long time to change the thickness of gold to make it stronger and more durable.
Hammer first, and then polish with a file to make the gold jewelry more delicate and smooth. Then check the interior of the jewelry. Sandpaper all the dead corners, and use grinding needles, grinding wheels, disc grinding wheels, and other tools for fine grinding, further shaping. Much of the gold cannot recover in the forging process, which adds to the cost.
Grinding needle, grinding wheel, disc grinding wheel, and other tools for fine grinding. This process is generally impossible to see in gold production because the loss is enormous.
After polishing, all the products will be handed over to quality inspection, which is to check the fine artistry and check the purity of gold with imported nuclear element gold meter. The qualified products will be put into storage. The unqualified products will be returned to the factory for re-production.
Note:Now we have replaced dangerous operations with machines
