Introduction of cooling forming method of ceramic needle gauge

In the process of obtaining precise zirconia ceramic needle gauge, ceramic finishing and molding methods are extremely important, and its molding method will affect its quality. Below, Kezhong Ceramic Factory will introduce the cooling molding method.

1. Vacuum method

The method of vacuumizing outside the pipe to make the outer surface of the pipe adsorb on the inner wall of the shaping sleeve and cool to determine the outer diameter. This method is especially suitable for the extrusion of ultra-high molecular weight polyethylene ceramic needle gauge structural parts.

2. Internal pressure method

It is a method that compressed air is pressurized in the structure of ceramic needle gauge, and a cooling setting sleeve is added to the pipe, so that the outer surface of the pipe is attached to the setting sleeve, and the pipe is quickly cooled and hardened to determine the outer size, and the pipe is uniformly led out by a traction device.

3, sizing mouth sizing (ejection method)

In this method, the ceramic needle gauge structure is directly ejected for molding without a traction device. The structure of the ejector die is characterized in that the straight part of the core die is about 10-50mm longer than the die, and the pipe is pushed out of the die by the screw thrust and directly pushed into the cooling water tank, so that the outer surface of the pipe is cooled and hardened, and the inner surface can not shrink inward and be shaped when sleeved on the mandrel.
