Have you ever wondered how some products feel soft in your hand yet remain strong and durable? Overmolding is the process that makes this possible. By combining rigid substrates with flexible materials like TPE, silicone, or rubber, overmolding creates parts with ergonomic grips, soft-touch surfaces, and improved resistance to wear and environmental conditions. As an […]
