Have you ever wondered how manufacturers secure caps on their bottles? According to Market.us, Coca-Cola sells over one billion bottles of cola every day. That is a lot of bottles, and that is just one major company. The Coca-Cola company, and many other businesses, would not be doing nearly as well without the help of cap closing machines and rotary automation. What is a capping machine?
Cap closing machines seal bottles of all shapes and sizes once full (liquids or solids). Beverage bottles, medicine bottles, and household cleaning products are all manufactured with these machines. The machines carefully line up bottles and lids before placing caps and securing them. A cap closing machine does just what its name implies, but different types of cap closing machines exist to meet the demands of different industries.
Inline Capping is the most used method of adding caps to bottles because it seamlessly works for different caps and containers. The machine also boasts speeds of up to 200 caps per minute (this number depends on the configuration of containers and the size of caps). These systems often use air load clutches or springs to control torque.
Snap Capping is a specialized machine that is almost exclusively used in NEPCO applications. It uses the same principles as an inline capping system, but it applies minimal pressure when securing caps. The system is less expensive than any others because it has few moving parts.
