Square shaped shims and round shims are common fasteners used for connecting gaps and distributing stress between bolts, nuts, and connecting parts. They help reduce friction, limit deformation, transfer pressure, and prevent leaks.
Wire Cutting Process: Uses energized metal wire to melt material without direct contact. Ideal for hard metals and small-lot production with no burrs.
Laser Processing: Uses laser beam heat energy for precise cutting of complex shapes. Best for materials 0.05 to 2mm thick and small production runs.
