Companies in the Household Home & Farm Refrig (Manufacturing) industry are involved in the production of refrigerators and freezers for household, home, and farm use. These appliances are designed to keep food and other perishable items at low temperatures to prevent spoilage. The industry includes the manufacturing of both standalone refrigerators and freezers, as well as combination units that include both functions in one appliance. The production process for these appliances involves a range of activities, including design, engineering, and assembly. Manufacturers must source a variety of materials, including metal, plastic, and insulation, to create the finished product. Quality control is an important aspect of the manufacturing process, as refrigerators and freezers must be able to maintain consistent temperatures over long periods of time.
