There are many different types of plastic moulding, most of which is manufactured in China. Depending upon which type of plastic moulding is used would determine the way the moulding is fitted.
The resulting moulding with incomplete filling of the plastic resin is called in practice as short moulding.
Cove or crown moulding which is fitted at the junction of a wall and ceiling.

Two common plastic groups used for heat and moulding plastics are thermoplastics, which can be melted and remoulded multiple times through heating and cooling processes, and thermosetting plastics, which undergo a chemical change during moulding and cannot be remelted or reshaped after the initial moulding process.

Mold Setup and Design: An accuracy mold, typically steel, is designed particularly to replicate the part shape of interest. Precious Enterprises Pune, India, provides service to develop high-strength and precise high-quality injection mold bases. Material Preparation: Dry plastic pellets (ABS, polypropylene) are fed in the machine hopper. Melting and Injection: Pellets are melted in a barrel to molten state and high-pressure injected (1,000–30,000 psi) into the mold cavity. Cooling: The melt of the plastic freezes and solidifies inside the mold and assumes shape. Ejection: The mold is opened and the finished part is ejected. Finishing: Trimming or surface grinding for finish can be done on parts, a service Precious Enterprises performs well. Precious Enterprises offers specialty mold bases for injection molding that offer precision and reliability to many industries.
It is made in factories, usually by injection moulding.
Sony makes fitted plastic/vinyl PS3 covers in many different colors.
They're made using plastic injection moulding.
Blow moulding is when plastic granules are injected into a mould after being melted, and then compressed air is blown into the mould to hollow it out. This can make shapes like bins and bowls.
Plastic cups can be made up of a number of materials, polypropylene, polyethylene, polycarbonate. Depending on the detail required there are also a few manufacturing process that would be appropriate. Injection moulding is good for high levels of detail but is expensive. Rotational moulding is not as precise but alot cheaper.
