1: Mold making and processing: According to the requirements or sample specifications, first make a blister mold. Under normal conditions, gypsum is used to make blister packaging molds, but wood carving and metal carving products are also used as molds, and gypsum molds are made. After that, let it dry completely naturally or dry, and then according to the specific conditions of the product surface, use a 1-2 mm drill to drill many small holes in the low concave place that does not affect the packaging appearance of the product, if it is a product such as a packaging box , It is necessary to drill some small holes on the four sides so that the air can be pumped out during blister production. After the holes are drilled in the mold, the gypsum mold has to be hardened. The hardening treatment method is to soak in concentrated alum saturated solution. After drying. [1]
2: After the mold is completely dried, put the mold on the upper iron plate of the vacuum chamber, and then load the plastic sheet into the applicable size according to the size of the mold, and then put the sheet into the heating wooden cabinet to make it completely fixed , and then put the wooden cabinet together with the plastic sheet on the constant temperature furnace for softening treatment.
3: Put the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch, and suck out the air in the vacuum chamber. After the plastic sheet is cooled, the same concave package or process mold as the mold is obtained.
4: Blister packaging and finishing; Trimming and finishing the produced products are finished products, and they can be sold after packaging.
