In the primary mixing and blending process of the rubber and tire industry, high-viscosity materials such as carbon black, silica, oil, and chemical additives are mixed under high temperature and pressure, causing strong friction, impact, and wear simultaneously.

Yuil Tech supplies components such as chambers, rotors, mixing blades, liners, and screws to major clients including Hankook Tire and Kumho Tire, and also provides refurbishment and repair services using hardfacing technology.

Chamber

Measures internal wear depth → applies hardfacing layer via welding → finishes with surface grinding

Optional buffer layer applied to prevent hard layer cracking

Rotor

Precisely measures and welds worn blade angles for accurate repair

Applies vibration reduction technology for stable high-speed rotation

Screw & Feeder

Wear from particle friction during dispersion and transfer → hardfacing welding or thermal spray coating applied

Liner / Mixing Blade

Surface cracking from repeated high-viscosity friction → repaired with composite hardfacing or replaced with domestic alternatives
