Special-shaped hooks not specified by JIS standards are also possible.
The material used is "Piano Wire Type A, SWP-A," with a wire diameter of Φ3.5. The body part is processed using a core wire type winding machine. For small lot production, we can achieve cost advantages compared to processing with a multi-forming machine. To manage the initial tension, we use a winding machine with NC control to regulate the winding hardness. The initial tension refers to the force with which the wires in the body part try to adhere to each other, and it can be adjusted by our manufacturer's force. The hook on the right side is a "U hook," while the hook on the left side is a special shape not specified by JIS standards. Both hooks are smaller than the body, but of course, they can be processed to be smaller or larger. After spring forming, heat treatment (low-temperature annealing) is performed, and rust prevention oil is applied before shipping. If you have any concerns regarding "springs," please feel free to consult us. Our technical staff will respond carefully.
