Material Certifications & Compliance
We prioritize strict raw material control to prevent incorrect alloy grades, material mix-ups, and substandard recycled stock. Using an Oxford spectrometer for on-site chemical composition analysis, we verify material authenticity and consistency before production. All incoming materials are managed through batch traceability and sample retention, effectively eliminating quality risks at the incoming material stage before entering production.
We work exclusively with certified material suppliers and never substitute material specifications without prior customer approval. All materials comply with ISO, RoHS, and REACH requirements. Material certificates, incoming inspection records, and full compliance documentation are available upon request, ensuring consistent performance and complete traceability for long-term production.
