PET Vacuum Forming Sheet Extrusion Line Machine For thermoforming Printing Package

Description:

The PET sheet production line consists of a feeder, a hopper, an extruder, a screen changer, a melt pump, a melt runner, a mold, a three-roll forming machine, a cooling bracket, a silicone oil drying device, traction trimming, and collection. Roller and other components. At the same time, according to the specific needs of customers, the design of the PET sheet production line will still be slightly different.

(1) If customers require multilayer PET sheets, the number of extruders needs to be increased. Three-layer PET sheet needs at least two extruders, which can produce PET sheets with ABA structure; it can also be customized according to customer requirements. 5-layer PET sheet, if the sheet structure is ABCBA, then 3 extruders are required, and a distributor is required in front of the mold to adjust the distribution ratio;

(2) According to the purpose of PET sheet, the auxiliary equipment equipped on the PET production line is different. If customers use PET sheets to make blister products, such as plastic electronic product packaging, parts packaging, fast food boxes, plastic cups, etc., then the production line needs to be equipped with silicone oil coating and drying equipment, which is beneficial to PET sheets In the later stage, it is molded on the blister machine and demolded; if the PET sheet produced by the customer is not used for thermoforming, this part can be removed, which can also save the customer the equipment purchase cost; if the PET sheet produced by the customer needs to be used for post-printing Or it can be combined with other materials, then a corona machine needs to be added to the PET sheet equipment. The corona machine can treat the surface of the PET sheet; if the surface of the PET sheet produced by the customer needs to be smooth and bright, it can be on the PET sheet line Increase the upper and lower laminating devices to cover both the front and back sides of the PET sheet with a protective film;
