GST automatic blister packaging machine manufacturers first explain that the size of blister packaging can be divided into three types: copying according to customer samples (mold making is called complex mode), making molds according to drawings, and designing according to the actual object. Because the shape of the blister is generally customized according to the actual object, the shape is often irregular, and many dimensions are inaccurate or cannot be marked when the drawing is made, so there is a large deviation when making according to the drawing. For the sake of accuracy, it must be accompanied by a physical trial. The size deviation of the product made according to the sample complex mold will not be very large.
The general thickness tolerance of blister packaging is 0.1mm, and the product deviation is ±2mm. The main reasons for the tolerance are:
1. The deviation caused by manual mold removal. This deviation is generally less than 2mm.
2. The deviation produced when the seed model replicates the child model. This deviation is small, generally less than 0.5mm.
3. The thickness deviation of the same mold due to different materials and blister temperatures. This deviation is small, generally less than 0.1mm.
4. The thickness tolerance depends on the specific situation. The larger the same area is stretched, the thinner the thickness of the block will be. Different operators and different temperatures will also make the thickness of the same part different.
Among the above reasons, the first one is the main reason for the dimensional tolerance, but because the mold can be modified and corrected, the deviation of the blister can generally be controlled within 2mm.
It should be noted that the thickness of the material is two numbers (0.05mm) smaller than the thickness of the finished product. Although there are such phenomena that when the surface area of the finished product is much larger than the surface area of the material, the thickness of the finished product will be much smaller than the thickness of the material, the surface area of the finished product is much larger than the surface area of the material, and the thickness of the finished product will be much smaller than the thickness of the material, but overall Generally speaking, the general gap is 0.05mm. Blister is a very clear "tailor-made" product. If you want the right size, you must take the real thing to try it on.
