Thick‑plate thermoforming, also known as thick‑plate vacuum forming, refers to a process in which the primary raw material used has a thickness exceeding 2 mm. Such parts cannot be produced on a fully automated, intelligent thermoforming machine; instead, they are manufactured using a semi‑automatic thermoforming press specifically designed for producing architectural thick plates.

　　Thick‑sheet thermoforming: characteristics and common classifications. The production process for thin‑sheet thermoformed packaging is similar, primarily relying on vacuum thermoforming. Thick‑sheet thermoforming refers to products made from raw materials with a thickness exceeding 2 mm; such items cannot be formed on a fully automated, intelligent machine and are instead manufactured using semi‑automatic thermoforming equipment specifically designed for thick sheets.
