Description

Technical Field

[0001] The utility model relates to the technical field of PETG sheet processing, and more specifically, to a pressing device for PETG sheet processing. Background Art

[0002] PETG sheet offers outstanding toughness and high impact strength, 3 to 10 times that of modified polyacrylates. It also boasts a wide processing range, high mechanical strength, and excellent flexibility. Compared to PVC, it offers greater transparency and gloss, is easily printable, and offers environmental advantages. PETG sheet facilitates the production of complex shapes and high-stretch ratio products. Furthermore, unlike PC and impact-modified acrylic, PETG sheet does not require pre-drying before thermoforming. Compared to PC or acrylic, it offers shorter molding cycles, lower temperatures, and higher yields. However, further processing of PETG sheet requires lamination of multiple sheets. Existing PETG sheets are prone to horizontal shifting during lamination, reducing the effectiveness of the lamination process. To address this issue, we have developed a lamination device for PETG sheet processing. Utility Model Content
