Explanation:

Process manufacturing, a class of manufacturing which is associated with the formulas and the manufacturing of recipes. This type of manufacturing is different from discrete manufacturing as it deals with discrete units and assembly of the components.

This type of manufacturing is common in food, chemical, beverage,  nutraceutical, pharmaceutical, cannabis, and mostly biotechnology industries. In this manufacturing, the relevant factors are the ingredients and the bulk materials rather than the individual units.

Thus, formation of ice is an example of process manufacturing in which different ingredients are added and using recipe of freezing.
