Product Overview

Engineered to protect structures from ground-borne vibrations and dynamic loads, this vibration isolation pad has been adopted across sectors where vibration control is critical. Applications include nuclear power plants, substations, booster stations, data centers, radar stations, semiconductor fabs, precision machine tools, hospitals, schools, offices, clubs, communication buildings, museums, art galleries, memorial halls, and facilities handling chemicals, toxic substances, or hazardous materials. It is also suitable for buildings directly affected by traffic or machinery vibration, as well as critical structures within lifeline engineering systems. In all these settings, the pad provides reliable passive and active isolation.

Product Features

This isolation pad supports various vibration control needs through multiple installation methods to accommodate different site-specific conditions. On-site installation is straightforward, and construction progress is rapid. Once in place, it delivers a long service life with stable, consistent performance. It also operates reliably in harsh environments, including tunnels.

Mechanical & Chemical Properties

The pad offers excellent buffering capacity, supporting loads up to 30 t/m², and delivers outstanding passive and active isolation effects. It is suitable for use as a plane bearing under cast-in-place concrete slabs. Resistant to chemical attack from oil, acids, and alkalis, the pad withstands high static and dynamic stresses, with a compression set of no more than 5%.

Quality Assurance

Raw material control: Every incoming batch is lab-tested before being accepted into the factory. Production only begins once the batch meets our specified property requirements.

In-process quality checks: Sampling inspections are performed at three stages – pre-production, in-process, and post-completion.

In-house testing capability: All tests are conducted in our own laboratory, which holds CNAS accreditation. This means our test results are recognized under international standards.

Lead time: 7 to 30 days, not including design or mold development. ap1

Production Capacity & Delivery

We handle Prefabricated Slab Track Vibration Isolation Pad production inhouse at our dedicated continuous foaming workshop. The facility runs on an automated German production line, giving us consistent quality and high output. Current annual capacity stands at 900,000 square metres of Prefabricated Slab Track Vibration Isolation Pad.

For delivery, lead times are flexible. Depending on customers’ order quantity and specifications, we typically ship within 7 to 30 days after order confirmation.

Custom Mould Design & Manufacturing

– In-House, Start to Finish

Our Mould Engineering Department operates a full digital workshop equipped with more than 20 CNC machines, including machining centres, spark eroders, and wire cutters. This allows us to design and manufacture a wide range of moulds for the rail transit industry – injection moulding, rubber, SMC, and specialised types such as auto-core-pulling bush moulds.

Annual output stands at 300 sets of moulds and tooling.

If your project calls for a non-standard shape for Elastic Ballast Mat, a special material, or a unique production feature, we have the equipment and the experience to deliver.
