Quality Control at Tingko: Ensuring Precision and Reliability

At Tingko (Shanghai) Co., Ltd., quality control is the cornerstone of our Swiss-type CNC machining operations. We adhere to strict protocols, including 100% inspection coverage and compliance with IATF16949 standards (planned certification). Our process involves initial material verification, in-process monitoring with real-time data logging, and final product validation to achieve tolerances as tight as 0.005mm. With a dedicated quality assurance team of experienced engineers, we minimize defects and ensure every part meets client specifications for industries like automotive, medical, and communications. This commitment to excellence supports our 100% on-time delivery rate and 40% export business to Europe and America.

At Tingko, every machined part undergoes rigorous 100% inspection to guarantee tolerances down to 0.005mm, ensuring unmatched precision for global clients.

Our quality control system integrates advanced tools like Hexagon CMM for dimensional accuracy and Mitutoyo roughness testers for surface finish evaluation. We conduct regular audits and traceability checks throughout the production cycle, from raw material intake to final packaging. This proactive approach not only prevents issues but also drives continuous improvement, aligning with our quality policy of excellence and sustainable operations. Clients benefit from detailed reports and certifications upon request, fostering trust in our high-precision Swiss-type machining services.

In our workshop, quality extends beyond inspection to include employee training and process optimization. All 17 team members are trained in lean manufacturing principles, reducing waste and enhancing efficiency. We handle micro parts with minimum diameters of 1 mm using Japan Star SB20R machines, where quality control is embedded in every step. From automotive transmission parts to medical stapler components, our QC measures ensure durability and performance, backed by 24-hour shifts and full compliance testing. This results in zero-tolerance for errors, positioning Tingko as a reliable partner in precision manufacturing.
