(1) Improper selection of blister molding process
Inflatable plug pressure-assisted technology can be used instead.
(2) The blister sheet is too thin
A thicker sheet should be used instead.
(3) Uneven heating of the blister sheet
The heating system should be checked, and the temperature of the part that will form the corner of the product should be lower. Before pressing, some cross lines can be drawn on the sheet material to observe the flow of the material during forming, so as to adjust the heating temperature.
(4) Uneven temperature of blister mold
Should be properly adjusted to uniformity.
(5) Improper selection of blister materials
The raw materials should be replaced.
