 Forming solutions for Ceramic Shell of Mobile

 
There are three kinds of forming solutions available for Ceramic Shell of Mobile subject to diversified  powder formulations.
Solution 1: Dry Presssing + Cold Isostatic Compaction Treatment
Applicable powder: good dispersion of binder, good powder forming performance, high strength of green body
Forming equipment: YS350 servo CNC ceramic mobile phone back plate special hydraulic machine, dry pressing mold, plastic film bag, vacuum heat sealing machine, cold isostatic press.
Description of the forming process:
The first process: pre-forming, the powder is put into a dry pressing die and preformed on a special hydraulic machine of the YS350 servo numerical control ceramic mobile phone back plate to obtain a dry compact body.
The second process: vacuum packaging, the preformed blank is placed in a PVC film bag, and vacuum-packed on a small vacuum heat sealing package machine.
The third process: cold isostatic pressing, the vacuum-sealed preform body is hung in the hanging basket of the cold isostatic press, and the sealing cylinder is pressurized to 180 MPa or more, and the cylinder is taken out after being pressed and relieved. The film bag with the blank body is blown and cut into the film bag to take out the pressed ceramic mobile phone back plate blank.
Solution 2: Dry Pressing + Warm isostatic Compaction Treatment
Applicable powder: poor dispersion of binder, good powder forming performance, high strength of green body
Forming equipment: YS350 servo CNC ceramic mobile phone back plate special hydraulic machine, dry pressing mold, plastic film bag, vacuum heat sealing machine, warm isostatic press.
Description of the forming process:
The first process: pre-forming, the powder is put into a dry pressing die and preformed on a special hydraulic machine of the YS350 servo numerical control ceramic mobile phone back plate to obtain a dry compact body.
The second process: vacuum packaging, the preformed blank is placed in a PVC film bag, and vacuum-packed on a small vacuum heat sealing package machine.
The third process: warm isostatic pressing, the vacuum-packed preform body is hung in the hanging basket of the warm isostatic press, and the sealed cylinder is heated to about 80 ° C for a period of time, and then pressurized to 180 MPa or more. After holding pressure and pressure relief, the cylinder is taken out to cool the basket, and the film bag with the blank body is taken out, and the film bag is blown and cut out to take out the pressed ceramic mobile phone back sheet body.
Solution 3: Dry Bag Isostatic Forming
The ceramic powder is placed in a static pressure die such as a dry bag and directly formed by a static pressure bag of 180 MPa or more, thereby saving powder and processing cost.
