Blistering is a thermoforming production process. In the process of manufacturing plastic boxes, the combination of temperature control and time has a direct bearing on the molding quality of plastic molding.
All blister boxes are heated using film and then formed. In this process, the three factors of temperature, time and cooling are closely inseparable. Because the materials are different, or because the same material, but the sheet thickness is not the same, there are many same materials and sheet thickness, but because of the specific structure of the plastic box, so in the process of processing, for each parameter The settings will also be very different. All this must have very rich operational production experience to be competent.
PET blister boxes usually have lower temperature settings than PVC. Excessive temperatures can affect the transparency of PET blister boxes. In the process of molding PET, the time from softening to cooling is usually shorter than that of PVC. Therefore, the production of the same structure of plastic products, PET blister has more output.
PVC, whether it is baking time or heating temperature will be higher than PET, but it is not absolute. The plastic box produced by PVC is better than the PET plastic packaging box in terms of fit. Under certain conditions of use, this characteristic of PVC is not a substitute for PET. In theory, during the processing of PVC, slow heating, and then slow cooling, so that the PVC blister permeability produced by the above will be significantly improved. Many new blister operators tend to follow this rule, either consciously or unknowingly. In the general case, according to this operation, significant quality improvement can be seen in some products. However, in many cases, there is basically no finding that the blister packaging produced in this manner of operation has a lifting effect that can be discerned by the naked eye.
Blister high-speed machine operators to adjust the parameters according to the actual situation, practitioners do not have a parameter to produce all the things. With the increase in the number of years of work, many blister operators experience will become more and more abundant. Many technical personnel with more than 10 years of operating experience will soon know how much temperature to adjust, both sides and in the middle, as soon as they see the blister mold. What is the temperature difference, whether it can be successfully released, how to set the plastic cooling molding.
