Air Intake System

Dust Contamination and Abrasion

Root Cause

• High dust environment (construction / mining sites)
• Poor sealing at hose joints
• Long-term particle abrasion on inner wall

Our Solution

• High sealing silicone hose structure
• Tight-fit end reinforcement design
• Abrasion-resistant inner layer formulation

Productivity

• Prevents dust ingress into engine
• Protects turbocharger and air filter system
• Improves combustion efficiency and engine life

Hose Cracking from Vibration

Root Cause

• Continuous engine vibration
• Rigid mounting stress points
• Aging of standard rubber materials

Our Solution

• High-flex silicone elastomer
• Fabric-reinforced vibration damping structure
• Optimized bend radius design

Productivity

• Prevents fatigue cracking
• Improves long-term durability
• Stable air intake under off-road conditions

Intercooler System

Pressure Expansion / Burst

Root Cause

• Turbo boost pressure spikes
• Weak reinforcement layer structure
• Heat softening under continuous load

Our Solution

Multi-layer reinforced silicone + fabric/aramid
• High burst pressure design margin
• Thermal-stable compound formulation
• Controlled wall thickness engineering

Productivity

• Prevents hose burst under peak boost
• Maintains charge air system integrity
• Stable engine power output

Heat Fatigue and Softening

Root Cause

• Continuous high-temperature turbo air
• Heat cycling (hot → cool → hot)
• Poor thermal resistance material

Our Solution

• High-temperature silicone compound (-40°C to +220°C)
• Anti-aging formulation design
• Heat cycling resistance structure

Productivity

• Maintains elasticity under long-term heat exposure
• Prevents deformation and hose collapse
• Extends service life in engine bay

Application Cases in Heavy Equipment Systems

Demonstrating how our engineered hose solutions improve reliability and performance in excavator and heavy machinery applications.

What Customer Gains

■ Stable Engine Power Output—Consistent airflow ensures optimized combustion efficiency

■ Reduced System Failure Risk—Eliminates hose burst, leakage, and deformation failures

■ Extended Maintenance Cycle—Longer service life compared to standard rubber hoses

■ Improved Machine Uptime—Reduces unexpected downtime in harsh jobsite conditions

What Are the Operating Conditions

• Temperature: -40°C to +220°C (peak hot air conditions)

• Pressure: 0.2 – 2.5 bar boost pressure (turbocharged system)

• Environment: High vibration, dust, oil mist exposure

• Duty cycle: Continuous heavy-load operation (mining / earthmoving / construction)

Why Our Hose Works

• High Temperature Resistance

• High Boost Pressure Resistance

• Reinforced Structure (Fabric / Wire Reinforced)

• Dust & Oil Mist Resistance
