Without cap tighteners, factory workers today would still be closing the company's products with the power of their own wrists and arms. Modern capping machinery, even the smaller electric table-top models, can handle 25 caps a minute and save a small business worker from carpal tunnel syndrome and a number of other health problems. With the investment of a cap tightener, any size business can benefit.

There are a number of different types of cap tighteners, starting from electric models to pneumatic ones. Pneumatic tighteners utilize the power of a air motors to create torque while electric ones work very much like hand-held power tools. An inertial cap tightener is built with an electric motor suspended above the operator along with a flexible and maneuverable shaft connected to the chuck.

A business must take careful consideration when choosing between all these varying types of cap tighteners. Table top tighteners are better for caps larger than 65 mm in diameter, while certain torque requirements may require stronger and more powerful machines. If the company is expecting a lot of bulk product to be processed throughout the day, a faster and more versatile machine (such as electric cap tightener with a fractional horsepower motor and adjustable cap width) is recommended.

Explosion-Proof Cap Tighteners

With certain volatile products, metal containers with metal caps, or plastic containers non-smooth necks a pneumatic tightener is best. These are great for flammable or corrosive materials, gas canisters, paints and spoilable food products. Even large assembly line cap tighteners can successfully and safely close and seal these and other dangerous liquids.
