Quality Certifications and Compliance

We are quality.

For CSS, it is more than an external requirement. Quality-by-design principles are rooted in the culture here at CSS, defining all of our processes and everything we do. We were one of the first in our industry to become ISO certified in 1994 and among the first to manufacture and distribute precision parts internationally. We have continued to dedicate ourselves to a consistently high standard of quality worldwide, surpassing what our customers typically expect from a supplier or a partner.

We live by defined quality management systems. Whether the application is medical, defense/firearms, aerospace or government, we follow established standards and procedures for each industry so that we can deliver consistent and dependable products. We meticulously plan every tooling and component project, from incoming order processing and work instructions to production and shipping.

The American Systems Registrar has audited and approved Connecticut Spring & Stamping for quality management systems applicable to the design, support and manufacture of springs, wire forms, metal stampings, and tooling and for the assembly of springs, stampings and purchased components.
