Steps to Wax the Jewelry

The purpose of jewelry waxing is to make the jewelry more beautiful and prevent oxidation. Next, Casting Machines Manufacturer will explain the steps of jewelry waxing.

1. Wax injection is the melting of the wax by the Jewelry Wax Injector and then injected into the mold by air pressure. The equipment usually used is a vacuum wax injection machine. The basic principle is that the gas in the film is discharged by vacuuming before the wax is injected, and the molten wax is injected into the mold by air pressure. The advantage of vacuum wax injection is that the filling property is better, and the thinner wax mold can also be injected, and the wax mold has fewer bubbles.

2. When waxing, depending on the complexity of the wax pattern of the jewelry, different pressures and temperatures should be selected. When the design pattern of the jewelry wax mold is simple or large, the temperature and pressure of the liquid wax in the Jewelry Wax Injector should be lowered. When the design pattern of the jewelry wax mold is delicate and complicated, the temperature and pressure of the liquid wax in the Jewelry Wax Injector should be increased. Before waxing, the mold should be opened first to check the integrity and cleanliness of the mold.

3. In order to make the jewelry wax mold well detached from the rubber mold, talcum powder is generally used as a lubricant, and baby talcum powder can also be used instead. During the operation, open the rubber mold as much as possible to make the talc powder pour into every corner of the rubber cutting surface. The best way to do this is to blow off the excess talc powder with pressurized air after the rubber mold has passed the talcum powder, and the talc powder can be injected for 3-4 pieces of glaze after each talcum powder is thrown by the rubber mold, and then the talc is reused. Powder is more appropriate. The talcum powder is not used too much to avoid the rough surface of the wax tray.

4. When using the Jewelry Vacuum Wax Injector to make a jewelry wax model, in order to obtain a wax mold with a smooth surface and high precision, two aluminum sheets with a thickness of about 2 mm are attached to the upper and lower surfaces of the rubber mold during operation. And use your fingers to evenly press the entire rubber mold and align it with the wax nozzle of the Jewelry Vacuum Wax Injector. Since the rubber mold has elasticity, the shape of the wax pattern is distorted according to the pressure of the hand. To prevent this phenomenon, the pressure of the hand should be kept at a certain size.
