Ceramic Bulletproof Plate Forming Solution

According to different powder formulas of customers, Mach provides three solutions for forming ceramic bulletproof plates:
Scheme 1: Dry pressing preform cold isostatic pressing compaction treatment
Applicable powder: good binder dispersion, good powder forming performance, high blank strength
forming equipment: YK1500-3000 two-way special ceramic hydraulic press, dry pressing mold, plastic film bag, vacuum heat sealing machine, cold isostatic press. Description of
forming process:
first process: pre-forming, putting the powder into the dry pressing die and pre-forming on the YK1500-3000 two-way special ceramic hydraulic press to obtain the dry pressing blank.
The second process: vacuum packaging, the pre-formed body into a PVC film bag, in a small vacuum heat sealing packaging machine vacuum packaging.
The third process: cold isostatic pressing, the vacuum-sealed preformed blank is hung in the hanging basket of the cold isostatic press, the sealing cylinder is pressurized to above 180MPa, the cylinder is opened after pressure is maintained and released, the pressed film bag containing the blank is taken out, and the pressed ceramic mobile phone back plate blank is taken out by blow drying and cutting the film bag.
Scheme 2: Dry Pressing Pre-forming Warm Isostatic Pressing Densification Treatment
Applicable Powder: Poor Binder Dispersion, Good Powder Forming Performance, High Body Strength
Forming Equipment: YK1500-3000 Two-way Special Ceramic Hydraulic Press, Dry Pressing Die, Plastic Film Bag, Vacuum Heat Sealing Machine, Warm Isostatic Press. Description of
forming process:
first process: pre-forming, putting the powder into the dry pressing die and pre-forming on the YK1500-3000 two-way special ceramic hydraulic press to obtain the dry pressing blank.
The second process: vacuum packaging, the pre-formed body into a PVC film bag, in a small vacuum heat sealing packaging machine vacuum packaging.
The third process: warm isostatic pressing, the vacuum-sealed preformed body is hung in the hanging basket of the warm isostatic press, the sealing cylinder is heated to about 80 ℃ for a period of time, and then pressed to more than 180MPa. After pressure maintaining and pressure relief, the cylinder is opened to take out the hanging basket for cooling, the film bag containing the body is taken out, the film bag is blown dry and cut to take out the pressed ceramic mobile phone back plate body.
Case 3: Dry Bag Isostatic Pressing
Put the powder into the dry bag isostatic pressing mold and form the dry bag isostatic pressing at a pressure above 180MPa.
