QC Profile

1. Dimensional Inspection

The first step is verifying the "unloaded" physical specs using high-precision calipers or optical measuring systems

 

2. Torque and Deflection Testing

Since torsion springs provide rotational force, a specialized Torque Tester is required.

 

3. Material and Surface Quality

The durability of a spring depends on its "skin" and internal structure.

4. Load Life & Fatigue Testing

For safety-critical parts (like garage door springs or automotive components), manufacturers perform "cycle testing."
