Customization from Concept to Completion: Provide us with your force, deflection, space, and environmental specs. We handle the design, prototyping, testing, and high-volume production.
-
End-to-End Quality Assurance: Our process includes load testing, fatigue testing, salt spray testing, and dimensional verification to ensure every spring meets its specified performance criteria.
Our Engineering & Manufacturing Process
-
Design & Analysis: Our engineers use industry-standard calculations and software to model spring performance, ensuring the design meets your functional requirements before production.
-
Prototyping & Testing: We produce physical samples for validation, conducting force-deflection tests and fit-checks in your assembly.
-
Precision Manufacturing: High-speed CNC spring coiling machines, followed by stress-relieving heat treatment and secondary operations (grinding ends, forming hooks).
-
Surface Finishing: Apply appropriate finishes such as zinc plating, powder coating, passivation, or oil coating for corrosion protection and performance.
-
Packaging & Logistics: Packed in bulk boxes, or on reels/bands to prevent tangling, tailored to your assembly line needs.
