Spring products have extremely high requirements for dimensional accuracy, elastic coefficient, fatigue strength, and geometric tolerances. Especially for high-end products such as precision springs, special-shaped springs, automotive-grade springs, and medical springs, even minor errors can lead to product scrapping and affect the service life of downstream equipment. In traditional production, manual equipment parameter adjustment and manual operation are prone to hand tremors, visual errors, fatigue mistakes and other issues, resulting in poor product consistency and a high reject rate.
Automated production lines adopt a numerical control programming mode. By inputting core parameters such as spring wire diameter, mean diameter, number of coils, pitch, and angle in advance, the equipment can accurately execute each process, with dimensional errors controlled within ±0.01mm, completely eliminating quality fluctuations caused by human factors. Equipped with an online intelligent inspection system, technologies such as electromagnetic induction, visual recognition, and laser ranging are adopted to conduct full inspection of spring dimensions, elasticity, surface defects, coil count and other indicators at the second level. Unqualified products are automatically sorted and rejected, realizing 100% full-process quality control and preventing defective products from entering subsequent processes or the market. In long-term production, product quality is highly consistent, with the pass rate increased by more than 20% compared with manual lines, perfectly meeting the stringent standards of the high-end manufacturing sector and helping enterprises build a high-quality brand reputation.
