Blister Boxes is a packaging product widely used in various industries. Its production process includes several key steps.
The first is design and molding. Designers use professional design software to design Blister Boxes according to the shape, size and packaging requirements of the product. After the design is completed, the blister mold is made by engraving machines, EDM machines and other equipment. The quality of the mold is directly related to the precision and appearance of the Blister Boxes, so this step is crucial. During the molding process, it is necessary to ensure that the mold size is accurate, the surface is smooth, and it has sufficient strength and durability.
The next step is sheet selection and heating. According to the purpose and requirements of Blister Boxes, choose suitable plastic sheets, such as PVC, PET, PP, etc. The sheets are placed in the heating equipment and heated evenly by heat radiation or heat conduction. The heating temperature and time need to be strictly controlled to ensure that the sheets reach the appropriate softening degree for subsequent blister molding. If the temperature is too high or the time is too long, the sheets may be over-softened or even burnt; if the temperature is too low or the time is too short, the sheets will not soften enough and cannot be molded.
Then comes the blister forming. The heated and softened sheet is quickly transferred to the mold of the blister forming machine. The negative pressure generated by the vacuum pump makes the sheet tightly adsorbed on the mold surface to form Blister Boxes that are consistent with the shape of the mold. In this process, the parameters such as the pressure, vacuum degree and forming time of the blister forming machine need to be adjusted according to the properties of the sheet and the requirements of the product. The formed Blister Boxes need to go through a certain cooling time to ensure that their shape is stable.
The formed Blister Boxes also need to be trimmed and sorted. The excess edge material is cut off to make the edges of the Blister Boxes neat and smooth. At the same time, the Blister Boxes are inspected and defective products are removed.
Finally, it is packaging and storage. Qualified Blister Boxes are packaged to prevent damage during transportation and storage. Packaging materials can be selected from cartons, plastic bags, etc. When storing, care should be taken to prevent Blister Boxes from being affected by adverse environmental factors such as direct sunlight, humidity and high temperature.
In short, the production process of Blister Boxes requires key steps such as design and molding, sheet selection and heating, blister forming, trimming and sorting, and packaging and storage. Each step requires strict control of process parameters to ensure the production of high-quality Blister Boxes.
