1. Mold making and processing: According to the requirements or sample specifications, it is necessary to make a good vacuum forming mold. Generally, gypsum is used to make vacuum forming packaging molds, but Dongguan packaging materials also use wood and metal carving products as molds. After the gypsum mold is made, it should be naturally dried or dried first. Then, according to the specific situation of the product's surface convexity and concavity, 1-2 millimeters of drill holes should be used to drill many small holes in the low concave areas that do not affect the product packaging appearance. If it is a packaging box or other product, some small holes need to be drilled around it so that the air can be extracted during vacuum forming production. After drilling the holes in the mold, the gypsum mold needs to be hardened. The hardening treatment method is to soak it in a saturated solution of concentrated alum and air dry it.

   
   

2. After the mold processing is dry, the mold is placed on the upper iron plate of the vacuum chamber. Dongguan Packaging Materials | Then, according to the size of the mold, the plastic sheet is loaded into the appropriate specification size, and then the sheet is placed in a heated wooden cabinet to be 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 a vacuum chamber, turn on the suction switch, and clean the air in the vacuum chamber. After the plastic sheet cools down, the same concave packaging or process mold as the mold is obtained.

4. Blister packaging organization; The finished product is produced by trimming and organizing the edges, and can be sold after packaging.
