Product Detail

Superior Shock Absorption Efficiency: The composite structure of high-density polyurethane core layer combined with a wear-resistant coating achieves a shock absorption efficiency exceeding 85%. This significantly reduces equipment vibration amplitude, helping operations meet relevant noise standards and protecting both equipment and surrounding structures from vibration-induced damage.

Easy Installation: The plate requires no special installation tools and can be fixed via pre-embedded bolts. This design simplifies mounting and replacement, reducing installation time and labor costs.

Durable Construction: The polyurethane core is oil-resistant and aging-resistant, maintaining stable performance in various environments including exposure to lubricants, hydraulic fluids, and process chemicals. The wear-resistant coating protects the core layer from mechanical damage during installation and service.

Industry Applications

Equipment Original Vibration Isolation

Ideal as original shock absorption components for vibrating screens, centrifuges, and flotation machines. The >85% efficiency reduces transmitted vibration to support structures, extending equipment life.

Building & Structural Base Support

Perfect for custom product base support feet and equipment pedestals. Reduces structural vibration transmission and protects building foundations from cyclic fatigue damage.

Steel Structure Floor Ground Pads

Suitable as shock absorption pads under steel structure floors and walkways. Effectively reduces foot traffic and equipment collision noise while protecting floor coatings from impact damage.

FAQ

What does "shock absorption efficiency >85%" mean in practical terms?

Shock absorption efficiency measures how much vibration energy is absorbed by the plate rather than transmitted through it. An efficiency >85% means that less than 15% of the incident vibration energy passes from the equipment to the supporting structure.

Practical effect: If a vibrating screen generates 10mm of vertical vibration amplitude at its feet, a standard steel base plate might transmit 8mm to the floor (>80% transmission, <20% absorption). This shock absorber plate would transmit only 1.5mm to the floor (85% absorption, 15% transmission).

For noise reduction, a 10dB reduction in transmitted vibration corresponds to a 50% reduction in perceived loudness.

Pre-embedded bolts are cast into the shock absorber plate during manufacturing. The bolt heads are fully encapsulated within the polyurethane, with threaded ends protruding from the mounting surface.

Installation process:

  1. Position the shock absorber plate on the support structure

  2. Align pre-embedded bolts with mounting holes in the equipment base

  3. Secure with nuts and washers (standard tools only, no special equipment)

  4. Torque to specification

Benefits vs. separate fasteners:

  • No loose parts to lose or misplace

  • Consistent bolt spacing and alignment

  • Faster installation

  • No drilling required in the field

Yes. The polyurethane core is UV-stabilized for outdoor applications. The wear-resistant coating provides additional protection against:

  • UV degradation (prevents surface cracking)

  • Moisture (no rust or water absorption)

  • Temperature cycling (-30°C to 80°C for continuous operation; intermittent to 120°C)

For extreme outdoor environments (coastal salt spray, direct desert sun, freezing alpine conditions), specify the enhanced outdoor formulation.

Yes. This is one of the primary applications. Vibrating screens generate high-amplitude, continuous vibration that rapidly degrades standard rubber or cork isolation pads.

Why polyurethane excels for vibrating screens:

  • Fatigue resistance: Polyurethane withstands millions of compression cycles without cracking

  • Consistent performance: Shock absorption efficiency remains >85% throughout service life

  • Chemical resistance: Withstands process water, dust suppression sprays, and cleaning chemicals

  • Load capacity: Supports the full weight of large screens (up to 20 tons per unit)

Install one shock absorber plate under each screen support foot. For screens with 4-8 support points, use matched plates to ensure level operation.

Minimal maintenance is required:

  • Visual inspection: Quarterly, check for cracking, excessive compression, or coating damage

  • Torque check: Annually, verify mounting nuts remain at specification

  • Cleaning: Remove accumulated debris that might trap moisture or chemicals

Replacement indicators:

  • Visible cracking through the wear coating into the core

  • Permanent compression (thickness reduced by >10%)

  • Softening or sponginess (loss of load capacity)

  • Oil swelling (unusual expansion, typically only with incompatible chemicals)

Expected service life: 3-7 years depending on operating conditions.
