Background

With the development of Vacuum Insulation Panels (VIP), more and more profiled vacuum insulation panels are used. The special-shaped vacuum insulation panel is an empty insulation panel with a groove on the surface, and the groove is used for yielding a copper pipe or other assemblies. The method adopted in the industry at present is to use a groove pressing mould to press grooves with the depth, width and spacing meeting the requirements of customers on the finished product of the vacuum insulation panel. After the vacuum insulation panel is vacuumized, the barrier film and the inner core material are tightly pressed together by atmosphere, and the barrier film and the inner core material are pressed out of the groove, namely, the core material of the part is flattened, and the barrier film is stretched, so that the groove is formed.
