This invention discloses a method for manufacturing 3D display glass and its curved display glass, relating to the field of glass manufacturing technology. A conveying preheating box is attached to one side of the top of a multi-stage temperature control frame. Several pressure-equalizing hydraulic cylinders are equidistantly installed on the top of the conveying preheating box. Pressure-limiting fixing frames are attached to the bottom of the pressure-limiting fixing frames. Inlet and outlet electric slide rails are symmetrically installed at the bottom of the pressure-limiting fixing frames. Inlet and outlet sliding frames are installed at the bottom of the inlet and outlet electric slide rails via slide rail seats. A positioning electric slide rail is embedded at one end of the inlet and outlet sliding frame. A shaping top mold is fitted between two clamping fixing frames. This invention utilizes a combination of pneumatic hot bending, gravity hot bending, shaping hot pressing, and edge correction hot pressing. Furthermore, by using slow heating and slow cooling, along with mold control, the shape of the curved glass can be effectively controlled. Simultaneous operation of pretreatment and forming processes reduces the waiting time required during production.

This invention discloses a ball valve body anti-shrinkage casting module, relating to the field of ball valve body processing. It includes a casting main block, with a first guide post welded internally. The inner wall of the first guide post is lined with paraffin wax. This invention sets up a module by welding the first guide post to the inner wall of the casting main block and correspondingly welding a second guide post to the inner wall of the casting sub-block. One end of the first guide post is designed as a tapered structure.
