Injection molding is widely used for manufacturing parts with intricate figures. This process involves injecting molten elastomer into a mold cavity, which takes the shape of the desired part. While traditional injection molding methods properly produce simple geometries, achieving complex designs often necessitates unique challenges. Many techniques can be employed to overcome these challenges and enable the production of parts with complex geometries: * **Multi-Shot Molding:** This strategy involves using multiple injection units within a single mold, allowing for the creation of multi-material parts or intricate designs that would be difficult to achieve with a single shot. * **Insert Molding:** Inserts, such as metal components or electronic circuitry, can be placed within the mold cavity before injection. This approach allows for the seamless integration Injection Molding Process of functional elements into the molded part. * **Co-Injection Molding:** This process involves injecting two or more different materials simultaneously into the mold cavity. It permits the creation of parts with varying properties and visuals. By meticulously selecting and implementing these techniques, manufacturers can create complex geometry parts with high precision and quality.
