Small Conical Springs
We produce tailored small conical springs with wire diameters 0.3mm–2.0mm, large end OD 8mm–30mm, small end OD 3mm–15mm and customizable free height 10mm–80mm. Unique tapered structure brings nonlinear stiffness characteristics, and precise forming ensures stable support for every small conical springs.
Structural Advantages
Space-saving design
Coils can nest inside each other when fully compressed, resulting in much shorter solid height than equivalent cylindrical springs.
Stable support
Wider large-end contact surface effectively prevents lateral deflection during compression.
Progressive stiffness
Effective working coils reduce as compression increases, achieving gradual rising stiffness for nonlinear load demands.
Compact overall size
Ideal for miniature products with limited internal assembly space.
Materials & Surface Finishes
Carbon spring steel wire, stainless steel wire and piano wire are available. Surface options include natural finish, zinc plating, nickel plating and black oxide to meet anti-rust and appearance needs.
Application Fields
Suitable for electronic appliances, switch buttons, stationery, toys, small hardware and precision instruments with limited installation space.
Professional Special-Shaped Design Capability
Baoding Zhongxin Spring Manufacturing Co., Ltd. has rich experience in designing non-standard springs like small conical springs. Our engineers calculate optimal taper, wire diameter and coil quantity based on customers' installation space, load and compression stroke. Stress distribution and fatigue life are fully evaluated during design to guarantee reliable long-term operation. We deliver both standard stock sizes and fully customized structural solutions for all special elastic component demands.
