Silicon Steel Laminated Sheet Spring Clip | Precision Metal Stamping Clamp | Strong Core Fastening, Anti-Vibration, Easy Assembly for Motor & Transformer

Product Description:

The silicon steel laminated sheet spring clip is engineered to clamp and stabilize electrical core laminations in motors, transformers, inductors, and EV drive systems. Produced on progressive stamping dies, each clip delivers consistent spring preload and bite through serrated locking windows that anchor into the lamination stack without welding or rivets. Precision deburring and edge-rounding minimize burr height and protect coatings, while optional heat treatment maintains elastic performance over long service life.

Built from high-grade silicon steel or stainless steel in 0.20–1.00 mm thicknesses, the clip withstands varnish-baking and typical operating temperatures of rotating machines. Its symmetric “H” geometry equalizes force paths to prevent lamination flutter, reduce magnetostriction-related noise, and keep stack height uniform—improving reliability and efficiency. Surface finishes (bright, anti-rust, zinc plating or custom) provide corrosion resistance for harsh environments.

Dimensions, tooth geometry, and slot patterns are fully customizable to match EI, UI, stator/rotor, or special core layouts, and to suit manual press-fit or automated assembly lines. Tight tolerances and SPC-controlled production ensure repeatability; PPAP/IMDS, RoHS/REACH compliance, and material traceability are available on request. Supplied in trays, bulk, or tape-and-reel packaging, the spring clip shortens assembly time, reduces parts count, and delivers durable, vibration-proof fastening for a wide range of magnetic cores.
