3 cooling and shaping methods for zirconia ceramic structural parts

2. Zirconia ceramic internal pressure method

It is a method of pressurizing compressed air inside the zirconia ceramic structural parts, and adding a cooling shaping sleeve outside the pipe, so that the outer surface of the pipe is attached to the shaping sleeve and quickly cooled and hardened to determine the outer size. The pipe is evenly drawn out through the traction device.

3. Zirconia ceramic sizing orifice sizing (ejection method)

This method does not require a traction device and directly ejects the zirconia ceramic structural parts into shape. The characteristics of the head structure of the ejection method are: the straight part of the core mold is about 10-50mm longer than the die, and the screw thrust pushes the pipe out of the machine head. , directly pushed into the cooling water tank, the outer surface of the tube is cooled and hardened, and the inner surface is sleeved on the mandrel and cannot shrink inward to finalize the shape.
