In the pharmaceutical world, encapsulation refers to various techniques to enclose and protect the drug ingredients by forming the capsule shell. Encapsulation equipment changes depending on whether the manufacturer needs to produce a soft or hard gel capsule. For instance, encapsulation systems and machines for softgels control the entire process from start to finish because their shells are filled at the same time they are produced. On the other hand, the filling of hard gel capsules comes by separating the body from the cap, and after the filling operations, the two parts are sealed together again, forming the shell.
