The home appliance industry is a major consumer of polymer materials, utilizing them to manufacture aesthetic parts, casings, internal components, and technical parts for various products. Key requirements in this industry include surface quality, color stability, heat resistance, strength, and durability. After being compounded with masterbatches and necessary additives, the polymer raw materials are shaped—primarily through injection molding and extrusion, and in some cases, blow molding. Once cooled and ejected from the mold, the parts undergo finishing processes and quality control.
