Injecting wax: Melt the wax through Jewelry Wax Injector and inject it into the rubber mold with pressure. The rubber mold with wax is left for 2 to 3 minutes. After the wax mold is cooled, carefully remove the wax mold. The temperature of the molten wax during wax injection is adjusted according to the nature of the wax. The air pressure is adjusted according to the thickness of the wax mold, which is generally controlled at 4 to 10 air pressure, and the thick wax mold uses a higher pressure. When injecting wax, clamp the rubber mold with two pieces of aluminum plate or steel plate or plexiglass plate, hold the wax injection nozzle in both hands and press the foot control switch, and the wax injection starts. When the light goes out, the wax pattern is filled.

1. Wax injection is to melt the wax through a wax injection machine and then inject it into the rubber mold with air pressure. The currently commonly used equipment is a vacuum wax injection machine. The basic principle is that the gas in the rubber film is exhausted by vacuuming before the wax injection, and the wax in a molten state is injected into the rubber mold by using air pressure. The advantage of vacuum wax injection is that it has a good filling ability. It can also be injected from relatively thin wax molds, and there are fewer bubbles in the wax molds.

2. When injecting wax, different pressures and temperatures should be selected according to the complexity of the injected jewelry wax mold. When the design of the jewelry wax mold is simple or the area is large, the temperature and pressure of the liquid wax in the betting machine should be reduced. When the design of the jewelry wax mold is delicate and complicated, the temperature and pressure of the liquid wax in the wax injection machine should be increased. Before wax injection, the rubber mold should be opened first to check the integrity and cleanliness of the rubber mold.

3. In order to make the jewelry wax mold well off from the rubber mold, talc is generally used as a lubricant, and baby powder can also be used instead. During the operation, open the rubber mold as much as possible, so that talcum powder is puffed to each corner of the rubber cutting surface. The best operation method is to blow off the talcum powder with compressed air after the rubber mold has blown on the talcum powder, and each time the rubber mold blows on the talcum powder, 3-4 jewellery wax molds can be injected, and then the talc is reused Powder is more appropriate. Do not use too much talc to avoid roughening the surface of the wax tray.

4. When using a vacuum pressure wax injection machine to make jewelry wax models, in order to obtain a wax mold with a smooth surface and high precision, two aluminum plates with a thickness of about 2 mm should be added to the top and bottom of the rubber mold during operation, and evenly distributed with fingers. After pressing the entire rubber mold, align it on the injection nozzle of the wax injection machine. Due to the elasticity of the rubber mold, the shape of the wax mold will be distorted according to the pressure of the hand. To prevent this phenomenon, the pressure of the hand should be kept at a certain level.
