Using an isolated, shear-damping approach, Wolverine’s elastomer-coated materials control resonant modes that are active contributors to noise, vibration and harshness in oil pans. Our treatment of oil pans range from low- to high-thickness aluminum and magnesium castings, to steel-formed and deep-draw stampings. The combination of free damping outer isolation (rubber-coated steel), with “peel-and-stick” (PSA) viscoelastic adhesive polymers, provides exceptional damping and thermal management.
Strategic placement of isolated materials vs. mass coverage, guarantees a more cost-effective solution.
The materials used in oil pan treatments provide the ability to tune over a wide frequency bandwidth. It also:
- Improves modal damping – peak loss factor of .6 – .9 @ 70°F (21°C) with medium band temperature range
- Dissipates vibrational energy
- Reduces acoustic noise levels
Wolverine’s proprietary viscoelastic polymers, which are chemically bonded to metal, result in a composite that’s formulated for extremely high durability and extended life. The thin profile material also provides superior performance for high-heat insulation in environments up to 300°F (149°C).
Customizable Metals & Elastomer Thickness
The oil pan dampers or any other treatment can be customized based on your specific requirements.
Lightweight & Ultra-Thin Profile
Our materials are engineered for a perfect fit that meets tight clearance design requirements. Specialty thin-grade metal substrates and coatings are ultra-thin and lightweight compared to traditional foam and barrier-type options.
- External treatment without changing rib structure/shell design
- Improves acoustic radiation energy between 100 – 4000hz
- Bonding integrity without mechanical attachments
- Meets 800-hour pass-by durability testing at wide open throttle, under heat
- This treatment is effective in powertrain lower block and pan combustion noise for diesel cackle and low-frequency attenuation
