Edge-winding (ຊຶ່ງເອີ້ນກັນວ່າ 'No-Tooling-Cost' coiling) ກ່ຽວຂ້ອງກັບການ winding ສາຍແປ pre-tempered ເທິງແຂບຂອງຕົນ. ຂະບວນການນີ້ຮັກສາການໄຫຼເຂົ້າຂອງເມັດພືດຕາມເສັ້ນຮອບວຽນຂອງພາກຮຽນ spring, ເຊິ່ງຊ່ວຍເພີ່ມຊີວິດຄວາມເມື່ອຍລ້າແລະຄວາມສອດຄ່ອງຂອງການໂຫຼດຢ່າງຫຼວງຫຼາຍ. In contrast, stamping involves punching the spring from a sheet, which results in 'cross-grain' orientation at various points around the circle, creating weak spots susceptible to premature failure. Furthermore, edge-winding eliminates the scrap associated with stamping and allows for the easy production of multi-turn Crest-to-Crest springs with shim ends, which provide a $360^∘$ contact surface for more uniform load distribution.
