The tool is smoothly wrapped and processed to prevent scratches and scuff marks.
The material used is "Piano Wire Type A, SWP-A," with a wire diameter of Φ2.3. The shape of the hooks at both ends is "semi-round hooks." The hooks are formed using a multi-forming machine, which includes the hook processing. Since tension springs have the characteristic of concentrating stress (load) at the hook part, the processing tools are smoothly wrapped to prevent scratches and marks. After spring forming, heat treatment (low-temperature annealing) is applied to remove processing strain. The surface treatment is "trivalent chromate + baking." Springs of the same shape have also been successfully made from spring stainless steel wire, SUS304-WPB, SUS316-WPA, and Herculite. Our company handles the manufacturing, design, and prototyping of tension springs. Please feel free to consult us if you have any concerns.
