Arthropods molt (moult) in a process called ecdysis. It is necessary for growth because of the inflexibility of the exoskeleton. The old shell remnants are called exuviae.
Note that the term 'anthropod' should not be confused with 'arthropod'; anthropods are humans or humanoids and do not moult in the canonic sense.
There isn't only one thing that can happen to an exoskeleton on a growing arthropod. For some arthropods, such as Spiders, the exoskeleton grows as they do. For some other arthropods including crabs, it is necessary to shed their exoskeleton and grow a new one.
The act of moulting (molting) the Arthropod exoskeleton is called ecdysis.

It is called molting basically.
Ecdysis, or molting.

Molting
The body of arthropods is physically supported by an external skeleton (exoskeleton) made of a tough protein called chitin. Because it is inflexible, arthropods need to shed it entirely in order to grow in size.
Because of a process called Ecdysis (also known as moulting) arthropods are able to grow bigger. In ecdysis old exoskeleton is shed and new one (slightly bigger) covers the body.
Since arthropods have a rigid exoskeleton, in order to grow they need to moult their entire skin, then wait for the new exoskeleton to harden. Some of them eat the old exoskeleton in order to recapture the mineral content. Since many (like the crustaceans) are vulnerable during this stage, they need to hide for a while. The moulting process for some arthropods also integrates with the limb regeneration function.
Most only do so in larval/juvenile stages, when it's time to grow. Some arthropods such as tarantula females continue growing and molting until death. Also, when damage has occurred (torn off leg for example) molting can be induced earlier to develop and grow new appendages. :)
The external covering on arthropods is called the exoskeleton (or cuticle). It is made of a tough protein called chitin, a long chain polymer comparable to cellulose. Because it's inflexible, arthropods need to shed it (moult) in order to grow.
Yes, owing to their hard chitinous exoskeleton, arthropods are compelled to shed (moult) periodically in order to grow, a process called ecdysis.

an arthropod sheds it old exoskeleton when it has grown to a point where it needs a larger exoskeleton. This process is called ecdysis.

Yes. Arthropods have a skeleton on the outside, called an exoskeleton. (By contrast, vertebrates will have an internal skeleton or endoskeleton). The exoskeleton of arthropoda is made of a tough protein called chitin, a long chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals where it would be found in hair, nails, hooves, claws, beaks, etc. Some arthropods, like crustaceans, further harden their chitin exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed it (moult) in order to grow, a process called ecdysis.
