Introduction
A spring making machine should be evaluated with consecutive samples produced from the intended wire material.
Before purchasing equipment, manufacturers should confirm drawing revision, wire diameter, material, tolerance and testing conditions.
Important inspection items include outside diameter, free length, number of coils, end coil condition, squareness and load performance.
Continuous sample testing helps verify repeatability and production stability.
Machine selection should consider both forming capability and final spring performance.
To agree on a sample inspection plan, contact Jinchun with the spring drawing and load requirements.
