Quality Control Methods
·Raw Material Re-inspection: All raw materials come from qualified suppliers such as POSCO, ATI, Baosteel and other internationally renowned steel mills. Upon arrival, the QC team performs PMI composition re-inspection to ensure the material meets order requirements.
·Traceable production process: The main production processes include 100% laser welding, cold drawing, and bright annealing. Each production stage is supervised on-site by experienced engineers and technicians, with professional QC inspectors participating throughout and taking photos for archiving. The entire production process uses process cards, supporting full-process traceability.
·Pre-shipment full inspection: Siri Tubing has a professional QC team that conducts a series of inspections and tests on finished products, including routine appearance inspection, PMI composition verification, dimension measurement, and more. At the same time, special inspections such as airtightness testing, hydrostatic testing, and eddy current testing are conducted. Additionally, we support third-party inspections by SGS, TUV, and BV to meet the inspection requirements of international customers.
Santoprene TPV Encapsulation
Santoprene TPV (thermoplastic elastomer) combines the soft feel of rubber with the processability of plastic, offering excellent weather resistance, ozone resistance, and chemical resistance. With outstanding sealing performance and a comfortable tactile feel, it is commonly used in automotive seals, medical devices, and consumer goods. TPV is recyclable, aligning with environmental sustainability trends. Metro offers Santoprene TPV overmolding solutions to meet customers’ comprehensive needs for elasticity, durability, and aesthetic appeal.
