One of the most frequently asked questions in plastic injection moulding is, “What material should I use for my project?” The answer is not one-size-fits-all. Injection moulding offers a wide array of resins and material combinations, each with unique properties and characteristics. To assist you, we’ve compiled a list of the top 10 plastic injection moulding materials, along with their key features and typical applications.
