Certifications and Quality Management #
Yuan-Lih Knife Company states that its cutting tool products have passed multiple quality assurance certifications. The certifications listed on the official website are:
- ISO 9001 — Quality management certification, cited on both the Chinese and English versions of the website.
- ISO 14001 — Environmental management certification, listed on the English Quality Control page.
The company presents these certifications as evidence that its production processes comply with international standards and that both product quality and environmental protection are effectively controlled.
Quality Approach #
Yuan-Lih’s quality work is not limited to certification. The company describes the following practices:
- Material selection — Steel grades are chosen to suit the intended application, with hardening treatment adjusted for turning, milling and welding processes.
- In-house processing — Blade hardening and grinding are performed in-house, reducing dependence on outside contractors and communication errors.
- Precision grinding — Grinding targets small tolerances and good surface roughness, helping reduce friction during cutting and improve blade life.
- Traceability — Production records are kept clear and traceable so customers receive consistent products.
- Continuous improvement — Feedback from field use is used to improve material characteristics, edge sharpness and edge angles.
Certification Scope #
The official website does not publish a certificate download area or a detailed scope statement for each certificate. For current certificate numbers, validity dates and the exact products or sites covered, contact Yuan-Lih directly.
