√ Winding process control: The CNC spring machine monitors parameters such as wire feeding speed, winding angle, and pitch accuracy in real time to ensure consistent spring geometric with the mean diameter tolerance controlled within ±0.05mm.
√ Automatic detection control: Proprietary patent [Lifeng Spring Automatic Detection Control System Copyright] 24/7 automated monitoring of spring dimensions, elasticity,, and appearance defects, integrating PLC control, data acquisition, automatic judgment, and defective product sorting functions.
√ Heat treatment process monitoring: temperature uniformity controlled within ±5℃; atmosphere protection to prevent decarburization; oxygen content maintained below 0.1%; temperature monitoring system ensures the time-temperature curve meets process requirements; elastic limit fluctuation less than 3%.
√ Surface treatment monitoring: Electroplating layer thickness is sampled every 2 hours with a fluctuation range of ±2μm; salt spray test after passivation treatment verifies corrosion to ensure no red rust for 72 hours.
