Shape: The use of CNC machines with specialized cutting blades allows processing a variety of materials (PET, printed circuits, foam grout, 3M adhesive layer) with tolerances in microns. All cuts are clean and flat, creating a premise for assembling layers to achieve optimal fit, with no gaps for dirt to penetrate.
-
Layout: The CNC machine system integrates coordinate alignment technology (registration) based on reference points on the material surface. This ensures that the metal dome (Metal Dome) always lies exactly at the center of the electrical contact point, maintaining stability and uniform tactile feedback across the entire key matrix.

Modern technology:
-
Machining mechanism: Digital steel knife mold combined with variable speed CNC spindle, helps control cutting pressure to suit each material property (from hard insulation layer to soft foam grout).
-
Superiority: Extremely high repeatability is the core value of this technology, completely eliminating errors due to vibration or excess heat, helping HMI components achieve the highest durability in industrial environments.
