SDS Self Adhesive Dampers

SDS produce range of steel/aluminium vibration dampers which are available in 2000mm*1000mm, 2500mm*1250mm, 3000mm*1500mm or cut to size. The thickness of the material can be specified from 0.5mm up to 4.0mm (there is little advantage in using more than this)

Avoids Fabrication Issues. Folding a laminated SDS sheet can result in slippage between the two layers of steel. This is avoided by fabricating in the traditional way and bonding the SDS dampers on afterwards, acoustic benefits are not affected.

Avoids Welding Issues. Welding acoustic laminates can be tricky as the polymer often isolates the two layers of steel. One solution is to fabricate and weld the traditional way, then apply an SDS damper to the flat areas avoiding welds and folds. We are developing a laminate that can be easily welded.

Powder Coating. Laminates and dampers can be supplied with high a temperature polymer or silicone so dampers can be fitted prior to anodising or powder coating.

Low Cost Solution. SDS dampers are an effective way to solve potentially expensive noise issues. It is often just a simple case of applying a self adhesive damper to the vibrating panel. Covering 75% of the flat surface areas produces results similar to using a fully laminated sheet.

Lighter Construction Saves Costs.  The fabrication can be made out of a thinner gauge of steel as the constrained layer damping principle does not rely on mass to reduce vibration.

Metal Fatigue.  SDS also has the additional benefit of helping to reduce metal fatigue by damping out harmful vibrations & harmonics, which makes it ideal for vibratory feeders and chutes.
