Description

Technical Field

[0001] The utility model relates to the technical field of production of PET material blister trays, in particular to a PET material blister tray forming mould. Background Art

[0002] When producing PET material blister trays, it is necessary to use a blister mold for molding. First, the substrate is heated, and then the substrate is placed on the upper outer surface of the mold, and then air is evacuated so that the substrate can fit on the mold.

[0003] In the actual production process, the substrate is attached to the inner wall of the mold cavity by vacuuming. Since the vacuum holes are evenly distributed, the substrate can be attached to the middle of the lower end of the mold cavity. However, it is difficult to attach the substrate to the corners, which reduces the quality of the product. When the product is packaged later, it is difficult to completely place the product inside the blister tray.

[0004] Therefore, we propose a PET material blister tray forming mold. Utility Model Content
