In fact, the uneven thickness of the blister tray is also a normal phenomenon, experienced blister tray manufacturers can reduce this problem to the most reasonable range. Because it and the overall design, molding, molding and molding temperature control has a close and inseparable link. Therefore, in general, in the design of medical blister trays, ASTRO Packaging will not only consider the appearance and functionality of the product after molding, but also take the molding wall thickness into consideration. If the internal structure is too complex, it is necessary to grasp the positive and negative mold strength, temperature, time, etc., and try to control the wall thickness tolerance value.
At the same time, it is also affected by the way the mold is arranged. This is why there is a difference when customers compare samples with mass production goods. Because when making a sample of medical blister tray, it is made by one out of one mold and made by hand sample machine, all the parameters are well controlled and the wall thickness is relatively uniform. But when mass production according to different product size and structure of the mold, solid middle and side of the mold molding process wall thickness will be different, but for ASTRO Packaging, this difference is controllable.
