Industry Development Trends & Tech Integration

⚙️

High-Pressure Resilience

Modern Turbochargers and GDI (Gasoline Direct Injection) engines require oil circuit lines that can withstand extreme heat and fluctuating pressures. Our braided stainless steel and reinforced PTFE lines are designed for these exact environments.

🔋

New Energy Vehicle (NEV) Transition

The shift to Electric Vehicles hasn't eliminated the need for fluid lines; it has redirected it. We are now specializing in advanced cooling system pipes for battery thermal management and gearbox lubrication in hybrid models.
