How is lipstick materials combined and manufacture into its tube?

I need to know how lipstick is made so it is convenient to us and how the materials are combined to be hard.How is lipstick materials combined and manufacture into its tube?
Lipstick is mainly composed of wax. Of course, in the process of making lipstick, the wax needs to be melted first. Then the company adds in whatever ingredients it wishes that particular lipstick to contain - such as a certain pigment, a certain scent, and ingredients and materials that can decide the certain finish the company wants on their lipstick (shiny, matte, glossy...etc). All these ingredients are melted and mixed together and then gets poured into a mold probably a tube like container. They are then left to cool down and harden - wax hardens when its cooled. A machine from the manufacturing factory probably puts the lipstick into the pretty container (tube). Hope this helps!
