Tuned Compound Spring Isolator - Quality China Suppliers & Factory for Low-Frequency Vibration Control Solutions

,

Common applications of our advanced isolator include:
- Under punch presses and compressors
- Floating floor systems in buildings near rail lines
- Sensitive measurement and medical equipment
Compared to standard spring isolators, our tuned compound type provides superior isolation at low frequencies, eliminating the need for oversized springs.
Key benefits:
- The durable steel spring offers a low natural frequency, typically between 2–3 Hz.
- The tuned mass effectively absorbs energy at a designated target frequency.
- Built-in damping features prevent excessive motion during startup and shutdown, enhancing stability.
Materials:
- Q345B (structural steel)
- PA6GF (nylon 6 reinforced with glass fiber)
- NR (natural rubber)
- High-damping elastomer
Process:
- Rubber injection molding
As a leading factory and supplier in China, we are committed to providing high-quality isolators that meet various industrial needs.

    Application

    Widely used across China’s rail network, the Elastic Ballast Mat delivers proven results. Installed under the ballast bed, it boosts track elasticity, cuts down ballast breakage, and improves load distribution—especially on curves and turnouts. Designed with a puncture-resistant top layer and an elastic damping layer, Ballast Mat performs reliably with or without retaining walls.

    Quality Assurance

    We have designed, manufactured, and exported ballast mats for over 20 years. Our products are installed on more than 40 metro lines across major Chinese cities like Beijing, Shenzhen, Wuxi. Customer satisfaction stands at 98%.
    number
    Before leaving our factory, the ballast mats will be tested strictly according to standard requirements . For customers who require more, we carry out type tests at our in-house testing centre. 

    Tests include:
    • Fatigue testing
    • Static and dynamic stiffness measurement
    • Tensile testing

    This process verifies Elastic Ballast Mat reliability under real working conditions.

    Production Capacity

    We handle Ballast Mat production in-house 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 Railway ballast vibration reduction mat.

    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.
