Polymers injection moulding
WebJul 23, 2024 · Injection molding is a manufacturing process for producing parts in large volume – from thousands to millions. Melted resin is injected into a hollow mold until it is completely filled. The injection molding process uses high temperature and extreme pressure to sufficiently fill the interior with molten plastic resin or liquid polymers. WebCost. The cost difference between thermoset and thermoplastic injection molding is not black and white. While the thermoset process is typically slower—which equates to a higher cost—the material difference in …
