Railway Track
Growing noise and vibration concerns near metro lines pushed
us to create the tuned composite spring isolator. Unlike traditional damping
mats, it allows easy replacement and maintenance. The result: longer track life
and better ride comfort. Contact us for your project.
Background
Vibration and noise from metro and suburban rail affect
nearby residents, creating demand for line isolation solutions.
Current Solution
Current products like sleeper pads and floating slab mats
can't be repaired or replaced, raising lifespan concerns.
Core Customer Requirements
Better safety, repairable and replaceable design, plus lower
slab vibration.
Our Solution
Tuned composite spring isolator: repairable, reliable
vibration isolation, superior life cycle performance vs mats.
Result
Less worry, 10 dB vibration reduction, and a 50-year design
life.
Building Vibration Reduction
With more transit-oriented buildings demanding better
vibration and noise control, we've invested heavily in building isolation and
vibration-seismic dual-control products. These solutions reduce the impact of
metro, suburban rail, and even earthquakes on building structures.
Background
Vibration isolation for a transit-oriented building project
at Chengdu Donghu.
Core Requirements
Vibration control in transit-oriented development (TOD)
buildings.
Our Solution
Install continuous cast polyurethane CPU isolation mat for
vibration control.
Result
99% reduction in vibration and noise.
Applications
Floating floors, TOD projects, and more.

Industrial Equipment
With stricter environmental regulations, many large factory
machines need vibration isolation before installation to reduce ground vibration
and noise. Some power stations and substations also require isolation for
transformers and switchgear.
Background
Increasing environmental requirements
Core Requirements
Vibration and noise reduction for industrial equipment
Our Solution
Install polyurethane isolation mat under equipment
foundations
Result
99% reduction in vibration and noise.
Applications
Large factories, substations, etc.
