Aluminium Bobbins for Embroidery Machine — Smooth Thread Release

Small part, big difference. The bobbin is at the heart of every stitch — a warped or rusty bobbin means broken threads, uneven tension and constant stops. Weishili aluminium bobbins solve this at the source.
Made from lightweight aluminium alloy and machined to tight tolerances, each bobbin runs true at high speed and releases thread smoothly and evenly, keeping stitch quality consistent from the first minute to the last.

Lightweight aluminium construction — Less centrifugal load at high RPM, more stable tension and less stress on the rotary hook.
Rust-free and durable — Unlike steel bobbins, aluminium will not corrode, so bobbin thread stays clean and lint stays low.
Smooth, even thread release — Fewer thread breaks and bird-nesting, less downtime.
Trusted brand, boxed packing — Each box is factory-sealed, easy to store and re-sell in your shop.
Suitable for most commercial computerized embroidery machines (Tajima, Barudan, Dahao-controlled machines and similar 7.94 / 7.12 hook systems — confirm size before ordering). Stock up: embroidery workshops go through bobbins fast.
