Blister packaging production process

1. Mold making and processing: According to the requirements or sample specifications, firstly, the plastic molds are made. Under the general conditions, the plastic packaging molds are made by using gypsum, but the wood carving and metal carving products are also used as molds, and the plaster molds are well made. After that, let it dry naturally or completely, and then use the 1-2 mm drill to drill many small holes in the low concave of the product packaging without affecting the surface of the product. If it is a box or the like It is also necessary to drill some small holes in the periphery of the four sides, so that the air can be extracted when the plastic is produced, and the plaster mold is hardened after the mold is drilled, and the hardening treatment method is to soak with the concentrated liquid of the concentrated alum. Dry it out.
2. After the mold is completely dried, the mold is placed on the upper iron plate of the vacuum chamber, and then the plastic piece is loaded into a suitable size according to the size of the mold, and then the sheet is placed in a heating wooden cabinet to be completely fixed. Then, the wooden cabinet and the plastic sheet are placed on a constant temperature furnace for softening treatment.
3. Place the softened plastic sheet together with the wooden cabinet in the vacuum chamber, activate the suction switch, and vacuum the vacuum chamber air. After the plastic sheet is cooled, the same concave package or process mold as the mold is obtained.
4. Blister packaging and finishing; the finished products are trimmed and finished as finished products, which can be sold after packaging.
