Medical equipment: CT scanners, MRI machines, and other precision medical devices that require stable operation

Key function: Provide stable anti-vibration support, isolate external vibration interference, and ensure the accuracy of test results and equipment operation.

5.4 Home, Commercial & Special Equipment

This category covers daily-use and special-scene equipment, focusing on noise reduction and stability improvement:

Home appliances: Washing machines, refrigerators, air conditioner outdoor units, dishwashers, dryers

Commercial equipment: Large commercial freezers, treadmills, fitness equipment

Special equipment: Marine pumps, fans, marine air conditioning units, marine auxiliary equipment, cinema speakers, power amplifiers, stage lighting, audio equipment, recording studio equipment, HiFi equipment, trucks, engineering machinery

Key function: Reduce noise in daily use, prevent equipment displacement, and adapt to special environments (such as marine and outdoor) with corrosion and wear resistance.

Pre-installation Preparation: Ensure the foundation surface is flat, clean, and free of oil, dust, and debris. If the foundation is uneven, level it first to avoid uneven force on the shock pad. For 3D printers and precision equipment, ensure the installation surface is level to maintain equipment precision.

Pad Placement: Place the shock pads symmetrically under the equipment's load-bearing beams or feet. The number of pads should be determined according to the equipment's weight and size, ensuring uniform load distribution. For small equipment (such as desktop 3D printers), 4 pads are usually placed at the four corners.

Equipment Placement: Slowly place the equipment on the shock pads, ensuring that the equipment is level and the shock pads are not eccentrically compressed or partially suspended.

Fixation (Optional): For heavy equipment, use bolts to fix the shock pads to the foundation (avoid directly penetrating the rubber layer to prevent vibration short circuit). Anti-slip steel plates can be added between the pad and the equipment/foundation to prevent slipping. For light equipment such as 3D printers, fixation is generally not required.

Post-installation Check: After installation, check whether the shock pads are evenly compressed, whether the equipment is stable, and whether there is abnormal vibration or noise. For 3D printers, test the printing precision after installation to ensure vibration isolation effect.

Regular Inspection: Inspect the shock pads every 3-6 months. Check for signs of aging, cracking, bulging, creep, or uneven compression. For outdoor or harsh environment applications, shorten the inspection cycle. For precision equipment such as 3D printers, check monthly to ensure vibration isolation effect and printing precision.

Maintenance Notes: Avoid long-term overloading of the shock pads; avoid contact with strong acids, strong alkalis, and organic solvents; keep the surface of the shock pads clean. For 3D printers, avoid spilling resin or other chemicals on the pads to prevent rubber corrosion.

Replacement Criteria: Replace the shock pads if any of the following occurs:

① Severe aging, cracking, or bulging;

② Creep exceeds 10% of the original thickness;

③ Vibration isolation effect is significantly reduced, and noise increases obviously;

④ Service life exceeds 3-5 years (depending on working conditions).

For 3D printers, replace the pads immediately if printing precision is affected by vibration.

Do not use the shock pads beyond the rated load, otherwise, it will cause damage to the pads and affect the vibration isolation effect.

Do not install the shock pads in environments with concentrated strong acids, strong alkalis, or high concentrations of ozone, unless special rubber materials are selected.

When replacing the shock pads, stop the equipment first and ensure the equipment is stable to avoid safety accidents. For 3D printers, turn off the power and wait for the equipment to cool down before replacement.

Keep the shock pads away from open flames and high-temperature heat sources to prevent rubber aging and deformation.

Q1: How to select the appropriate rubber material for my equipment?

A1: Select the rubber material according to your working environment: For oil-containing environments, choose NBR; for outdoor environments, choose CR or EPDM; for high-temperature environments (such as 3D printers with heated beds and high-temperature fans), choose Silicone; for general dry environments, choose NR for cost-effectiveness.

Q2: Is the harder the rubber shock pad, the better?

A2: No. The hardness of the shock pad should match the equipment's weight and working frequency. Too hard pads have poor vibration isolation effect, while too soft pads may cause equipment shaking and resonance risks. For precision equipment such as 3D printers, it is recommended to choose 40°A-60°A hardness to balance stability and vibration isolation.

Q3: Can I stack multiple shock pads to improve the vibration isolation effect?

A3: Yes. Stacking multiple shock pads can adjust the static compression and natural frequency, improving the vibration isolation effect. However, it is recommended to add galvanized steel plates between layers to enhance load-bearing capacity and stability. For 3D printers, stacking 2 layers of thin pads is sufficient to achieve ideal vibration isolation without affecting equipment leveling.

Q4: What is the service life of the rubber shock pad?

A4: The normal service life is 3-5 years, which is affected by the working environment, load, and rubber material. For example, Silicone pads have a longer service life in high-temperature environments (such as 3D printers), while NBR pads have a longer service life in oil-containing environments.
