In the forming process of zirconia ceramic structural parts, both the sintering method and the cooling process will be used to obtain high-quality finished products. Next, Pintejin Ceramics will introduce the cooling and forming of zirconia ceramic structural parts.
Zirconia ceramic structural parts, also known as engineering ceramics, fine ceramics, etc., are inorganic non-metallic materials with high temperature resistance, wear resistance, corrosion resistance and relatively stable chemical properties.
1. Vacuum cooling molding of zirconia ceramic structural parts
The vacuum method of cooling and forming of zirconia ceramic structural parts adopts the method of vacuumizing the outside of the tube, so that the outer surface of the tube is adsorbed on the inner wall of the forming sleeve to cool and determine the outer diameter. This method is especially suitable for the extrusion of ultra-high molecular weight polyethylene ceramic needle gauge structural parts. Way.
2. Internal pressure cooling and forming of zirconia ceramic structural parts
The internal pressure method of cooling and forming of zirconia ceramic structural parts is to use pressurized compressed air in the zirconia ceramic structural parts, and add a cooling and setting sleeve to the tube to attach the outer surface of the tube.
3. Cooling and forming of sizing opening and sizing (ejection method) of zirconia ceramic structural parts
The zirconia ceramic structural part is formed by cooling and forming the diameter of the sizing hole (ejection method). This method does not require a traction device, and the zirconia ceramic structural part is directly ejected and formed.
The characteristics of the head structure of the ejection method are: the straight part of the core die is about 10-50mm longer than the die, the screw thrust pushes the pipe out of the head and directly into the cooling water tank, the outer surface of the pipe is cooled and hardened, and the inner surface is sleeved on the core The rod cannot be shrunk inward to form the shape.
The above is the cooling and forming of zirconia ceramic structural parts brought by Pintejin Ceramics. Pintejin Ceramics is a manufacturer specializing in the production and machining of ceramics, focusing on the machining of alumina ceramic parts and zirconia ceramics, and can process ceramic products according to your needs.
