It is necessary to select a suitable heat treatment furnace considering heating capacity, workability, maintainability, and environmental factors.
This introduction discusses "low-temperature annealing," a common heat treatment for springs that undergo cold forming. When springs are processed cold, residual stress occurs in the processed areas, leading to dimensional changes and a reduction in elastic fatigue strength. The purpose of this treatment is to eliminate that residual stress. Additionally, it also aims to improve the mechanical properties of materials that have undergone work hardening, such as piano wire, hard steel wire, and stainless steel wire, which are processed through cold drawing. [Objectives of this treatment] - Eliminate residual stress - Improve the mechanical properties of the material itself *For more details, please refer to the PDF document or feel free to contact us.

[Notes] <Extension Coil Spring> ■ If processed at temperatures exceeding 300°C after forming, the initial tension will be lost, so it is usually processed at 200 to 250 degrees. *For more details, please refer to the PDF document or feel free to contact us.*

Company information
To respond to the diversification of societal needs and the demand for small-batch production in cutting-edge markets, we have developed our own molds and tools, as well as high-performance machines, and adopted a multi-process automated production system linked with computers. As a result, we have gained wide trust overseas as RIKEN's springs. In recent years, we have also expanded our development and design into precision and functional assembly, from development to mass production. In the future, we aim to combine our theories with the latest manufacturing technologies through new ideas, hoping to be of service in various fields of society. As a company certified with ISO 9001 and 14001, we will sincerely strive to meet the needs of our customers, the market, and society.
