Precision Laser Cutting for 0.05mm (50μm) Magnetic Steel Sheet Applications in Miniature Electromagnetic Components And Instrument Spring Contacts

Precision Laser Cutting for 0.05mm (50μm) Magnetic Steel Sheet

Applications in Miniature Electromagnetic Components and Instrument Spring Contacts

Precision laser cutting of 0.05mm (50μm) magnetic steel sheets is ideal for manufacturing miniature electromagnetic devices, sensor components, and precision spring contacts used in instrumentation, control systems, and compact electronic modules. At this scale, maintaining structural integrity, shape accuracy, and edge quality is essential — all of which are achieved through high-precision laser micromachining.
