Precision Grinding
High-precision grinding ensures consistent, stable dimensions and elevates surface quality and product performance.
Half a century of precision craftsmanship — from piston rings and engine components to lithium batteries and energy-storage systems.
Every piston ring carries half a century of technology, quality and commitment.
“C.T.I.” originally stood for China Traffic Industry; the three letters also derive from the Spanish words Calidad (Quality), Tecnología (Technology) and Innovación (Innovation)
— the very philosophy C.T.I. lives by.
End-to-end control from raw material to shipment; every model is traceable.
Decades of precision grinding, surface treatment and materials engineering.
From combustion to storage — always seeking the next form of power.
Founded in 1973, C.T.I. Traffic Industries Co., Ltd. is one of Taiwan's earliest piston-ring manufacturers.
Starting from a single production line, we built our reputation on precision grinding and materials craftsmanship, supplying the global aftermarket.
We specialize in piston rings and oil rings, and also produce engine valves, overhaul gasket sets, carburetor repair kits, timing kits, and brake and chassis parts — widely used in automotive engines, agricultural and industrial machinery, heavy cranes and snowmobiles, exported to 110+ countries under one quality standard.
In 2018 we established our New Energy Division, developing power-battery applications for energy-storage and backup systems across the vehicle, construction, consumer and industrial sectors. We earned the world’s first UL1973 (12V / 5AH 1C) certification and launched the “12V/24V Auto-Sensing Jump Starter,” a smart vehicle-rescue system with high instantaneous current output, certified to CE, FCC and UN38.3.
High-precision grinding ensures consistent, stable dimensions and elevates surface quality and product performance.
Made from high-grade Japanese imported wire and cast-iron stock for outstanding wear resistance and durability.
From raw-material machining, heat treatment and surface finishing to final assembly — produced and managed entirely in-house.
Operating under the IATF 16949 quality management system, with strict process control through final inspection to ensure consistent quality that meets international standards.
Our New Energy Division develops lithium-battery modules and energy-storage systems (ESS), bringing half a century of manufacturing discipline to the energy transition. The same precision, a different kind of power.
Headquartered in Tainan, Taiwan — shipping to 110+ countries across five continents.
