1: Mold making and processing: According to requirements or sample specifications, first make a blister mold. Under normal conditions, plaster is used to make blister packaging molds, but wood carving and metal carving products are also used as molds, and plaster molds are made well. Then, let it dry completely or dry naturally, and then according to the specific situation of the surface of the product, use 1-2mm drill 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 necessary to drill some small holes on the four sides so that the air can be extracted during the production of blister. After the mold is drilled, the plaster mold must be hardened. The hardening method is to soak in a saturated alum solution. Let dry afterwards.

2: After the mold is completely dried, put the mold into the upper iron plate of the vacuum chamber, and then load the plastic sheet into the applicable specifications according to the mold size, and then put the sheet into the heated wooden cabinet to make it completely fixed , 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 to suck up the air in the vacuum chamber, and after the plastic sheet cools, you will get the same concave packaging or process mold as the mold.

4: Blister packaging and finishing; trimming and finishing the produced products is the finished product, which can be sold after packaging.
