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.
Magnetic cores, sensor arms, soft magnetic spacers
Used in miniature transformers, coils, electromagnetic relays, and actuators
Requires tight tolerance control and consistent magnetic properties
Thin spring sheets for sensitive measuring instruments, pressure sensors, and mechanical switches
50μm thickness provides both elasticity and responsiveness
Laser cutting ensures burr-free, high-repeatability production
Micron-level precision and clean edges
No mechanical stress or distortion
High repeatability in volume production
Capable of cutting complex geometries, slots, holes, and contours
Excellent for prototypes and mass production
Magnetic Stainless Steel (e.g., SUS410, SUS430)
Soft Magnetic Alloys (e.g., FeNi, FeSi)
Customized magnetic foils for EMI and inductive applications
