Polyurethane Vibration & Sound Isolation Pads for Recording Studios - China Suppliers & Factory

,

Enhance your sound control with our premium acoustic solutions, ideal for recording studios, KTV rooms, theaters, cinemas, and opera houses. Designed specifically for both new and renovated independent spaces, our products effectively manage impact and airborne noise.
Our innovative acoustic principle incorporates elastic materials and engineered open cells to absorb and reflect sound energy, significantly reducing transmission. The tailored perforation rate and pore size ensure optimal sound performance, making our products a top choice among China suppliers and factory standards.
Experience superior noise reduction with sound insulation rated ≥17 dB, providing effective blocking of impact noise across the entire frequency spectrum.
Manufactured through a meticulous continuous casting process, our products promise durability and resilience against corrosion, acids, alkalis, and oils. They are mold-proof, insect-proof, and resistant to aging, with a service temperature range from –20°C to +90°C.
Enjoy a long service life of over 60 years with minimal maintenance required. The high flexibility of our acoustic solutions ensures tight bonding with concrete slabs, eliminating the risk of hollow spots or deformation during installation.
Our products demonstrate excellent load performance with uniform stress distribution under both static and dynamic loads, supporting a load capacity of up to 5 t/m² without thickness loss.
Available in thicknesses ranging from 2 to 30 mm, these solutions meet flame retardancy standards ≥ B
We adhere to industry standards, including GB50118-2010, HG/T5328-2018, and align with in-house enterprise standards and client specifications. Choose our factory for the finest acoustic products tailored to your 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.
