We are adding a pressing process to flatten the hook.
The material is "Piano Wire Type A, SWP-A," with a wire diameter of Φ3.0. Both arms of this torsion spring are designed as hooks for assembling the wire. We received a request from the customer that "the hooks should be flat when viewed from the side." After the forming process, we add a pressing step to correct the hooks to be flat. A phosphate coating treatment has been applied for rust prevention. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully.
