This article offers a comprehensive overview of common plastic materials and the diverse types of figures they produce, highlighting how material choice shapes form, function, and appeal. It explains that plastic figures—lightweight, durable, and colorful—are primarily made from ABS, PP, PVC, or resin, with each material serving distinct purposes: ABS for complex structures, PP for child-safe toys, PVC for finely painted collectibles, and resin for premium, limited‑edition anime or game figurines. Action figures, typically crafted from PVC or TPR via roto‑casting or injection molding, boast smooth or matte surfaces, impact resistance, and vivid surface treatments such as painting, electroplating, or UV printing, making them staples of trendy toys and IP derivatives. Injection molding enables low‑cost mass production, while roto‑casting yields hollow, flexible yet durable figures with a texture between soft rubber and hard plastic. Resin figures, made from epoxy or PU resin using casting methods, excel in reproducing intricate details like skin textures and fabric folds, often enhanced by meticulous hand‑painting techniques for rich, lasting colors; though heavier, costlier, and more brittle, they hold high artistic and collectible value, with some using eco‑friendly bio‑based resins. Compared to plush figures, roto‑cast figures are more impact‑resistant and design‑versatile, though they feel colder in winter. Overall, the article illustrates how material properties, production techniques, and finishing processes converge to create figures spanning affordable blind boxes to high‑end collectibles across art toys, anime IP derivatives, and themed collections.
