Wine saucer Blister packaging box Specific production process:

1: Mold making and processing, Use 1-2 mm drills to drill many small holes in the low recesses that do not affect the appearance of the product packaging. If it is a product such as a packaging box, it is also necessary to drill some small holes on the four sides so that the air can be pumped out during the blister production. After the holes are drilled in the mold, the gypsum mold must be hardened. The hardening method is to soak it with concentrated alum saturated solution and then dry it. [1] 

2: After the mold is processed and dried completely, the mold is loaded into the iron plate on the upper layer of the vacuum chamber, and then the plastic sheet is loaded into the applicable size according to the size of the mold, and then the sheet is put into the heating wooden cabinet to make it completely fixed, and then the wooden cabinet and the plastic sheet are placed on the constant temperature furnace for softening treatment.

3: Place the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch, and suck the air in the vacuum chamber clean. After the plastic sheet is cooled, the same concave packaging or process mold as the mold can be obtained.

4: Blister packaging finishing; Trimming and finishing the produced products are finished products, which can be sold after packaging.
