We are adhering to the attitude of "human lives are at stake" to provide patients with "foolproof" products, for ASTMF136/67/1295 standard inspection content, Baoji Xinnuo to achieve further tightening and automation:
1. The dimensional inspection adopts 100% laser diameter measurement, which reverses the problem of undetectable dimensional consistency of manual sampling inspection
2. Ultrasonic inspection is tightened from Φ≥7mm as stipulated in the standard to Φ≥6mm, and supplemented by 100% eddy current inspection for non-ultrasonic detectable size products (Φ˂6mm).
3. Surface inspection is executed with 100% optical inspection to effectively avoid surface defects of bar material from missing detection.
In the product inspection link, those not required by ASTMF136/67/1295 standards are strictly implemented as follows.
1. A special inspection process is set up for longitudinal cut jamming passability to ensure 100% passability inspection.
2. For products outside the detection range (Φ˂7.0mm) specified in the standard, 100% eddy current detection is guaranteed.
