Light Duty Compression Springs
Our factory manufactures standard light duty compression springs with wire diameters ranging from 0.2mm to 1.5mm and outer diameters from 3mm to 20mm. Free height can be customized between 5mm and 100mm, featuring compact volume and gentle elastic force. Precise numerical control coiling ensures consistent soft elastic feedback for each light duty compression springs.
Product Features
Compact size
Minimum outer diameter reaches 3mm, perfectly fitting small finished goods and precision equipment with limited assembly space.
Gentle elastic force
Thin wire and dense coils create low stiffness, delivering sensitive deformation under tiny loads.
High sensitivity
Rapidly responds to minor force changes to realize precise force control and displacement feedback.
Light weight
Minimal material consumption avoids extra load burden for weight-sensitive products.
Materials & Surface Treatment
Optional raw materials include carbon spring steel wire, stainless steel wire and piano wire. Surface finish options: natural finish, zinc plating, nickel plating and black oxide to satisfy different anti-rust and appearance requirements.

Application Fields
Mainly applied to electronic appliances, precision instruments, stationery accessories, toys, switch buttons and small hardware with light loads and compact assembly space.
Precision Manufacturing Capacity
Baoding Zhongxin Spring Manufacturing Co., Ltd. is equipped with multiple CNC precision spring machines for stable production of micro springs starting at 0.2mm wire diameter. We adopt dedicated precision winding equipment for light duty compression springs, paired with skilled technicians to strictly control wire diameter, outer diameter, coil count and free height. Mature process schemes cover micro to medium-sized springs to fully meet diverse customized specifications.
