The Belleville spring washer, a century-old precision elastic component, was first developed by French engineer J. Belleville. Subsequent engineers refined its theory and established industrial standards (e.g., DIN 2092 and DIN 2093). The introduction of the national standard for Belleville springs has provided a unified production and quality benchmark for global spring technology, making it a fundamental component widely adopted in industrial applications.

Jiangsu Sunzo Spring Technology Co., Ltd. specializes in the R&D and manufacturing of disc springs, providing high-end customers worldwide with a diverse range of disc spring products. In recent years, the company has successfully developed a series of miniature disc springs with an outer diameter of less than 20mm, which are widely used in the electronics industry and have become a key driver of technological advancement.

In precision manufacturing, Sunzo employs automated stamping forming equipment to ensure dimensional accuracy and consistency of micro disc springs. Through multiple processes including quenching, tempering, polishing, and high-pressure sorting, the load-bearing capacity and service life of these springs are significantly enhanced. Notably, Sunzo's independently developed high-pressure sorter can process disc springs with outer diameters as small as 3mm, achieving high-precision automated sorting and has obtained national patent certification.



Sunzo's disc spring designs cover an outer diameter range from 2.20mm to 20mm, with a variety of product sizes including:
- 2.20*1.20*0.15*0.30
- 4.75*2.36*0.25*0.38
- 6.00*3.20*0.20*0.45
- 8.00*3.20*0.20*0.40
- 10.00*3.20*0.30*0.55
- 12.00*4.20*0.40*0.80

Micro disc springs are not only suitable for the electronic information industry but also applicable to other specialized industrial applications. Through continuous innovation in disc spring technology, Sunzo provides customers with highly reliable elastic solutions.
