What are the requirements for making film panels

Thin film panels are widely used in our daily lives, whether it is the outer shell of refrigerators, the surface of microwave ovens, the buttons of washing machines, the buttons of rice cookers, or the outer shell of remote controls. Its elegant figure can be seen. Structurally, thin film panels are mainly divided into two categories: convex and flat. When used as thin film switch panels, they all need to meet the following key conditions:

Dimensional stability: Thin film panels need to maintain dimensional stability within a certain temperature range (-40 ℃ to 55 ℃) to ensure normal operation in various environments.

Appearance quality: The surface of the thin film panel should be flat and smooth, with uniform gloss, and should not have any defects such as damage, scratches, or inclusions to provide the best visual effect.

Elasticity requirement: The thin film panel needs to have a certain degree of resilience, which can be determined by the elongation of the material. Materials with high elongation can provide better elastic deformation ability.

Weather resistance: As a surface layer exposed to natural environments, thin film panels need to be able to maintain stability under various natural conditions, without deformation, cracking, aging, and discoloration.

Chemical resistance: Thin film panels may come into contact with various chemicals, so they should have a certain degree of chemical resistance, especially to common mineral oils.

For raised film panels, the button parts are slightly raised, slightly higher than other panel parts. This design allows users to more accurately locate the button positions, thereby improving the convenience and accuracy of use.
