An apparatus for manufacturing a display apparatus includes: a first mold configured to accommodate a cover member thereon; a magnetic first guide in the first mold; a second mold arranged to face the first mold; and a magnetic shape-variable unit in the second mold. The shape-variable unit is configured to come into contact with and move a panel member toward the cover member, and a first portion of the panel member is configured to contact the cover member before a second portion of the panel member contacts the cover member due to a magnetic force between the shape-variable unit and the first guide.

A method of forming a material using a supersonic fluidic oscillator in a superplastic forming process and a related system. Pressurized gas, at a baseline pressure, is applied to a surface of the material when the material is received within a cavity of a forming tool. Pressure fluctuations, relative to the baseline pressure within the tool cavity, are created with a supersonic fluidic oscillator. Each pressure fluctuation (i) deforms the material and (ii) subsequently allows for a partial stress relief of the material during the forming process.

A packaging machine, comprising a control unit, at least one measurement device and a plurality of work units for different processes. One of the work units is designed as a sealing station which comprises at least one moisture sensor designed as the measurement device which is functionally connected to the control unit and is designed to detect moisture within the sealing station as a time-dependent measured variable during a program sequence of the sealing station. The program sequence may comprise an evacuation process, wherein the control unit is designed to calculate a rate of change in the moisture during the evacuation process of the sealing station. The control unit may abort the evacuation process performed on the sealing station, based on the rate of change, before reaching a target vacuum pressure within the sealing station, immediately or after a specified delay time elapses.
