Global environmental protection policies and circular economy regulations are profoundly promoting the material upgrading of the automotive injection molding industry in 2026. More regional regulatory frameworks require automotive suppliers to adopt recyclable, biodegradable and low-carbon polymer materials to reduce the carbon footprint of vehicle production. Bio-based plastics and recycled modified plastics are increasingly used in automotive interior parts, decorative accessories and non-load-bearing structural parts. At the same time, the industry has raised stricter standards for flame retardancy, high temperature resistance and dimensional stability of plastic parts, especially for electrical and battery system accessories of new energy vehicles. Factories are accelerating the upgrade of environmental-friendly molding processes and quality testing systems to meet global green procurement standards of international automobile brands, realizing coordinated development of product performance and environmental protection.
