How Do Manufacturers Keep Paper Shredders Quiet?

Paper Shredder Rubber BushingsHave you ever used a paper shredder that sounded like a lawnmower? I certainly have. Lawnmowers belong outdoors, not in the office. So how do manufacturers try and keep their paper shredders quiet? There are a few techniques used. Here are some of the most common “silencing” methods.

To begin, strip cut paper shredders tend to be quieter than cross cut shredders. This is because there is less cutting going on and fewer moving parts. The only downside is that strip cut shredders don’t provide as much security as cross cut shredders. Luckily many of our paper shredder manufacturers have made significant improvements in paper shredder noise.

Rubber Bushings – One significant improvement that many manufacturers are making is by using special rubber bushings in the design of their shredders. These bushings are placed around joins and mounting points where reverberations and vibrations are the worst. These rubber bushings act like motor mounts, dramatically cutting down on noise-making vibration.

Wooden Cabinets
– You’ll often find on many of the cheaper paper shredders that a lot of plastic is used in the construction. This is because plastic is cheap to use in manufacturing. The downside is that plastic can break and crack easily and has very few noise absorption properties. Many plastic cabinets used with lower-end shredders can even amplify sound. Most modern paper shredder manufactures try to use wood with their cabinets. Wood has natural noise absorption properties.

Auto Oilers – Many office and departmental paper shredders feature auto oilers. These auto oilers help keep moving parts and shredder blades properly lubricated, cutting down on metal-on-metal noise.

Tight Construction
– Tight construction, utilizing high quality bolts, screws and materials, can help cut down on sound by eliminating vibration caused by loosely fitted pieces. This feature is more difficult to tell with the naked eye and is generally a product of high-quality manufacturers.

Insulated Shredding Head – Some paper shredder manufacturers actually try and insulate the motor with noise absorption material, often called insulation. A well-insulated motor typically runs cooler and emits less noise.

What if you already own a shredder and it is loud? If you already own a shredder and are growing sick and tired of the noise, I highly recommend oiling it. You would be surprised how much noise can be reduced by eliminating friction in the shredder blades. Not only does this quiet a shredder, but it also prolongs its life.

Hopefully some of these tips help you in your quest to find a quiet shredder. Believe it or not, quiet shredders do exist, however, all shredders will make a little noise. You can find our entire selection of paper shredders here.
